1Be configured to row.
Like Fig. 2 and shown in Figure 3, support roller 10,11 is installed on roller section apparatus 20.Roller section apparatus 20 has: the framework 21 of interior all sides, install a plurality of in the support roller 10 of all sides; With the framework 22 of outer circumferential side, the support roller 11 that a plurality of outer circumferential sides are installed.Between the framework 22 of the framework 21 of interior all sides and outer circumferential side, be provided with holding components 23, this holding components 23 is used for the framework 22 of the framework 21 of all sides in these and outer circumferential side is supported, and support roller 10, interval between 11 are adjusted.In holding components 23, be provided with hydraulic cylinder 24.In addition, for example use piston rod or cylinder as holding components 23.Under the situation of using cylinder, holding components 23 is preferably the formation of adjusting its length through the form of screwing togather.For example, can adopt clip screw part and be divided into 2 parts formation, or between the framework 22 of holding components 23 and outer circumferential side the formation etc. of configuration screw part.
In the support roller 10 of all sides at the width D of casting sheet H
2On be divided into a plurality of, for example 3 cut apart roller 30a, 30b, 30c.Respectively cutting apart roller 30 becomes the substantial cylindrical shape, and the heart is inserted and is connected with at casting sheet width D therein
2The last axle 31 that extends.Respectively cutting apart roller 30 and axle 31 can be for the structure of one, also can be structure independently.In addition, axle 31 also can be cut apart through intermediate bearing portion 33 in the axial direction.Through said formation, cutting apart roller 30 can be the center rotation with axle 31.Be provided with end bearing portion 32 at the both ends of axle 31.In addition, the axle of cutting apart between the roller 30 31 is provided with intermediate bearing portion 33 (with reference to Fig. 2).Under the divided in the axial direction situation, dispose 2 bearings through intermediate bearing portion 33 at axle 31 in intermediate bearing portion 33.These end bearing portions 32 and intermediate bearing portion 33 are supported by the framework 21 of interior all sides.
At this; In the overlooking of that kind shown in Figure 4; With respect between two adjacent support roller (being the adjacent support roller in casting direction downstream and the adjacent support roller of casting direction upstream side) of 1 support roller, above-mentioned casting direction apart from B (mm), be defined as the distance of the central portion of each roller.
The inventor is the conscientious result of research repeatedly, finds in order to suppress the center segregation of casting sheet fully, and be inadequate at interval only through the casting direction between the adjustment support roller.On the other hand; Except above-mentioned adjustment; Through interval corresponding to the casting direction between the support roller, will be on casting sheet width in a support roller adjacency cut apart the suitable scope that is intervally adjusted between the roller, the inhibition effect of center segregation significantly improves thus.That is, found that it is inadequate only cutting apart the roller configuration through the adjustment of one dimension ground as in the past, also needs adjust the support roller configuration two-dimentionally and cut apart roller to dispose for the bulging amount of the reason that suppresses to become center segregation fully.Therefore; In a support roller; The non-support sector of cutting apart the casting sheet between the roller with adjacency on casting sheet width is divided into the center, to two adjacent support roller of the casting direction of striding this support roller (adjacent support roller in rear of support roller that the place ahead of the casting direction of observing from an above-mentioned support roller is adjacent and the casting direction observed from an above-mentioned support roller; Below also simply be recited as two adjacent support roller) the distortion of two-dimensional flat plate (casting sheet) of scope resolve, and estimated the bulging amount.In addition, according to the relation between bulging amount and the center segregation, derived above-mentioned formula (1), as the condition that is used for suppressing fully center segregation.
In addition, found that even under the situation that satisfies above-mentioned formula (1), it is excessive that the bulging amount also becomes, and can not suppress center segregation fully when being spaced apart 680mm when above between two of a support roller adjacent support roller.Therefore, in above-mentioned formula (2), higher limit is made as 680mm.
In addition, in above-mentioned formula (2),, be that decision is the actual minimum interval that support roller can be set in continuous casting equipment as the 400mm of lower limit.
As stated, in continuous casting equipment of the present invention, dispose support roller (cutting apart roller) with the mode that satisfies above-mentioned formula (1) and formula (2).Therefore, can reduce to cast the bulging amount of sheet, and suppress the center segregation of this casting sheet fully.
In addition, so-called center solid rate can be defined as the central part of casting the sheet thickness direction and the solid rate of casting the puddle of sheet width.
In addition, the center solid rate can solidify to calculate through heat transfer to be obtained, and solidifies as heat transfer and calculates known Enthalpy method and method of specific heat of equal value etc., uses which kind of method can.In addition, briefly known following formula also can use this formula.
Center solid rate=(liquidus temperature-fusing department temperature)/(liquidus temperature-solidus temperature)
At this, so-called fusing department temperature means the central part of casting sheet thickness direction and the temperature of casting the puddle of sheet width, can solidify to calculate through heat transfer and obtain.In addition, liquidus temperature for example can calculate with reference to " iron and steel, Japanese iron and steel institute can will, Vol.55, No.3 (19690227) S85, civic organization Japan iron and steel institute ", in addition, solidus temperature for example can with reference to " in normal times, golden ball, gloomy; Shake 19 the committee, the 5th solidification phenomenon association data solidified for 46 (December nineteen sixty-eight) " calculate.
That kind as shown in Figure 4 is cut apart roller 30 and is configured to so-called staggered (ZIGZAG SITITCH shape).That is, cut apart between the roller the gap with along the casting direction misalignment be one row mode dispose circuitously.In addition, in continuous casting, be more than 0.2 and among the support roller 10a less than 1.0 position at the center solid rate that being in of roller group 6 is equivalent to cast sheet H, constitute the interval of cutting apart roller 30 of support roller 10a, promptly at casting sheet width D
2Last adjacency cut apart interval A (following be called sometimes " non-tenaculum width A ") and the casting direction D of this support roller 10a between roller 30a, the 30b
1Two adjacent support roller 10b, the distance between the 10c (at interval) B (following be called sometimes " non-tenaculum length B "), formula (1) and the formula (2) shown in being set to below satisfying.The detailed description of these formula (1) and formula (2) with after state.In addition, the minimum of a value of non-tenaculum width A be made as and actual the value of cutting apart roller 30 can be set, for example for about 100mm.
A≤0.001×B
2-1.5×B+735 …(1)
400≤B＜680 …(2)
Wherein, A be among the support roller 10a at casting sheet width D
2Last adjacency cut apart the interval (mm) between roller 30a, the 30b, B is the casting direction D of support roller 10a
1Two adjacent support roller 10b, the interval between the 10c (mm).
Like Fig. 2 and shown in Figure 3, the support roller 11 of outer circumferential side is also same with the support roller 10 of interior all sides, at the width D of casting sheet H
2On be split into a plurality of, for example 3 cut apart roller 40a, 40b, 40c.Respectively cut apart roller 40 and form the substantial cylindrical shape, the heart is inserted and is connected with at casting sheet width D therein
2The last axle 41 that extends.Respectively cut apart the situation that there is the situation of the structure that becomes one in roller 40 with axle 41 and becomes standalone configuration.In addition, axle 41 is cut apart through intermediate bearing portion 43 sometimes in the axial direction.Through said formation, cutting apart roller 40 can be the center rotation with axle 41.Be provided with end bearing portion 42 at the both ends of axle 41.In addition, the axle of cutting apart between the roller 40 41 is provided with intermediate bearing portion 43.Under the divided in the axial direction situation, in intermediate bearing portion 43, need 2 bearings through intermediate bearing portion 43 at axle 41.These end bearing portions 42 and intermediate bearing portion 43 are supported by the framework 22 of outer circumferential side.In addition, identical with the planar configuration of cutting apart roller 30 of interior all sides of in Fig. 4, having explained about cutting apart the planar configuration of roller 40, so omit explanation.That is, support roller 11 with cut apart roller 40 and be configured to satisfy above-mentioned formula (1) and formula (2).
Effect to the continuous casting equipment 1 of formation as above describes.At first, the molten steel that is stockpiled in the tundish 2 injects mold 3 via nozzle 4.In mold 3, begin to cool down and solidify from the periphery of molten steel, form casting sheet H.Casting sheet H is pulled out to casting sheet path 5 from mold 3, and in by 6,7 guiding of roller group along casting direction D
1Side shifting downstream.At this moment, the support roller 10 in the roller group 6,7, the distance between 11 are adjusted to through roller section apparatus 20 and make casting sheet H become specific thickness.In addition, casting sheet H further cooling in through the process of casting sheet path 5, and be solidified to inside.
Then, above-mentioned formula (1) and formula (2) are described.The result that the inventor conscientiously studies repeatedly, finding needs to adjust the interval between the support roller, and need in a support roller, adjust the interval between the roller of cutting apart of adjacency in order to suppress the center segregation of casting sheet fully.That is, found to need adjust the interval between the roller for the bulging amount of the reason that suppresses to become center segregation fully two-dimentionally.
Therefore, as shown in Figure 4, in support roller 10a, to cast sheet width D
2The non-support sector of cutting apart the casting sheet H between roller 30a, the 30b of last adjacency is divided into the center, uses limited factors method, to expanding to the casting direction D of support roller 10a
1The deflection (below be recited as " bulging amount ") of casting sheet thickness direction of two adjacent support roller 10b, the two-dimensional flat plate till the 10c (non-tenaculum S) resolve, and estimated the bulging amount., the center solid rate of casting sheet H carries out the evaluation of bulging amount in being equivalent to the roller group 6 of 0.8 position.This center solid rate is more than 0.2 and in less than 1.0 scope.Because the center solid rate at casting sheet H is 0.2 or more and in less than 1.0 scope, confirmed in addition to take place to cast the bulging of sheet H and the situation that produces center segregation, so this center solid rate is set at its typical value.In addition, in non-tenaculum S, make in the scope of non-tenaculum width A below 400mm to change, non-tenaculum length B is changed with 450mm, 560mm, 600mm, 640mm, 680mm, and carried out the evaluation of bulging amount.
Fig. 5 representes the evaluation result of said bulging amount.The transverse axis of Fig. 5 is represented non-tenaculum width A.In addition, the longitudinal axis of Fig. 5 representes that with non-tenaculum width A be the ratio that 0mm and the non-tenaculum length B bulging amount when being 560mm is made as the bulging amount under 1 the situation, and it is defined as the bulging index.In addition, so-called non-tenaculum width A is that 0mm means the undivided situation of support roller.Though non-tenaculum length B becomes 280mm, in order to compare,, also non-tenaculum length B to be recorded and narrated for ease and be 560mm even be under the situation of 0mm at non-tenaculum width A with the undivided situation of support roller.
In addition, be under 0mm, the undivided situation of support roller at non-tenaculum width A, in fact as above-mentioned, exist owing to the support roller bending produces this problem of bulging.But at this, when the research of the situation that non-tenaculum width A and non-tenaculum length B are changed, in order to be the benchmark of the situation of 0mm as the minimum situation of bulging amount with non-tenaculum width A, being assumed to support roller can be not crooked and can operate.
At this, being 0mm and the non-tenaculum length B bulging amount when being 560mm with non-tenaculum width A as the basis of benchmark does, under the situation of using undivided support roller (A=0mm), and the casting direction D that sets usually
1Support roller be spaced apart about 280mm.Therefore, the inventor investigates discovery, when the bulging index is 2.8 when following, can suppress to cast the center segregation of sheet H fully.That is, found that the scope below the thick dashed line among Fig. 5 is to suppress the scope of center segregation.
Therefore, obtained that to satisfy the bulging index be such non-tenaculum width A of condition below 2.8 and the relation between the non-tenaculum length B.That is, under the situation that makes non-tenaculum length B change, obtaining the bulging index respectively becomes the non-tenaculum width A below 2.8.The non-tenaculum width A and the non-tenaculum length B that kind as shown in Figure 6 of this scope are illustrated.Then, the diagram among Fig. 6 is carried out polynomial approximation, derived the relational expression of above-mentioned formula (1).
In addition, as shown in Figure 5, can know that at non-tenaculum length B be under the situation more than the 680mm, even reduce non-tenaculum width A, non-tenaculum length B is also excessive, so center segregation integrally worsens.In addition, also can know when non-tenaculum width A is 0mm (promptly, use the situation of undivided support roller), be more than 2.0 when (scope on the fine dotted line among Fig. 5) at the bulging index, can not suppress center segregation fully.Therefore, in above-mentioned formula (2), the higher limit of non-tenaculum length B is made as 680mm.In addition, the 400mm as lower limit decides according to following situation in above-mentioned formula (2): in continuous casting equipment 1, at casting direction D
1The minimum interval that in fact support roller 10,11 of last adjacency can be provided with is 200mm.
According to above embodiment, the center solid rate that utilizes casting sheet H is that 0.8 situation is illustrated, but being equivalent to have carried out same result of experiment more than 0.2 and on less than a plurality of positions of 1.0, has all obtained result same as described above.
Such as previously discussed; According to the present invention; At the center solid rate that is equivalent to cast sheet H is more than 0.2 and in the roller group 6,7 less than 1.0 position; Support roller 10,11 (cutting apart roller 30,40) is configured to satisfy above-mentioned formula (1) and formula (2), therefore can reduce the bulging amount through the casting sheet H in the process of casting sheet path 5.Therefore, the center segregation of sheet H can be suppressed to cast fully, high-quality casting sheet can be made.
In addition; The device of a mode of the present invention can also be recited as as follows: a kind of continuous casting equipment; Possess and clip casting sheet path and a plurality of support roller of arranged opposite; It is characterized in that above-mentioned support roller is split into a plurality of rollers of cutting apart on the width of casting sheet, is more than 0.2 and in the support roller less than 1.0 position in continuous casting, at the center solid rate that is equivalent to cast sheet; In this support roller on casting sheet width adjacency cut apart interval A and the interval B between two adjacent support roller cutting apart the casting direction between the roller of adjacency on the above-mentioned casting sheet width between the roller, satisfy above-mentioned formula (1) and above-mentioned formula (2).
