Definitions
- the invention relates to a production process and a plant for endless
- slabs with a thickness greater than 120 mm or thin slabs with thicknesses between 40 and 120 mm are used as the starting material.
- the rolling mills generally consist of a single or multi-stand roughing mill in which the slabs are divided into several
- Rolling passes can be reduced in reverse operation, as well as a multi-stand finishing train or a Steckel stand.
- the almost uniform temperature over the length of the hot strip is achieved either by means of a coil box between the roughing and finishing mill, by speed-up in the finishing mill or by coiling furnaces in front of and behind the Steckel stand. In these cases it is a discontinuous process, i.e.
- the roughing and finishing lines generally work decoupled and roll the individual slabs.
- the foot is welded using a heating and pressing device.
- the seam between the two pre-strips is then mechanically processed before the pre-strip enters the finishing train.
- Rolling is then carried out endlessly on the finishing train, while the roughing train operates discontinuously. Disadvantages are those with one Problems related to process stability and hot strip quality in the area of the rolled-out piece of the seam.
- a ferritic or mixed austenitic-ferritic rolling is only possible with the structural transformation in the finishing train with the disadvantages already mentioned.
- the former consist of a multi-stand finishing train with an outfeed roller table
- the plants for thin slabs> 65 mm consist of a single or multi-stand structure due to the larger deformation work required for the same final thickness
- an outfeed roller table with devices for cooling the hot strip to winding temperature and winding machines for winding up the hot strip.
- the rolling mills are generally designed and operated so that the forming in the individual passes is fully austenitic or mixed austenitic-ferritic.
- the rolling temperature in all passes is above the GOS line of the iron-carbon diagram, whereby the final rolling temperature in the last stands of the finishing train should be close to the GOS line in order to achieve a fine-grained structure.
- the rolling temperature in the last stands of the finishing train below the GOS line is in the range of approx. 810 to 890 ° C
- Roll-in collapse due to the lower deformation resistance of the material in the ferritic temperature range leads to disadvantage for the roll bending and roll adjustment systems to ensure the thickness, profile and contour as well as flatness of the hot strip, since these systems use the measured rolling force as an output signal
- Compensating section of a few meters after the cooling section to the next stand is necessary. This is disadvantageous for austenitic rolling with a final rolling temperature greater than 890 ° C, because an increase in the spacing between the stands increases the temperature losses of the hot strip
- EP 0 761 326 A1 proposes a production system consisting of a multi-stand rolling mill, an outfeed roller table with devices for cooling the hot strip and downstream winding machines, in which at least the first stand is designed as a reversing stand, at least one reel furnace upstream and one downstream of which , whereby a controllable cow device is provided between the upstream reel furnace and the following reversing stand.
- the hot strip is rolled in the austenitic temperature area, the hot strip is cooled into the ferritic temperature area by means of the controllable cow device and wound up in the reel furnace.
- the structure change takes place in the reel furnace Rolling mill downstream of the coiler in the ferritic temperature range.
- the austenitic rolling process does not cool.
- the hot strip can be heated between the rolling mills using a heating device. Different arrangements scaffolding and
- Coiler furnaces are proposed In any case, the reversing operation is characteristic, as a result of which the proposed production plant cannot continuously roll endlessly.
- the coiler furnace or the additionally required increase the technical outlay on the plant
- Production plants for rolling hot strip from thin slabs are also known, in which facilities for cooling and heating are arranged after a single or multi-stand roughing mill. These facilities are a multi-frame finishing train with a run-out roller conveyor, facilities for cooling and winding machines for winding up the hot strip are generally carried out in of the roughing mill at least two passes in the austenitic temperature range, either in multiple stands in continuous operation or in a single stand in reversing mode.
- the hot strip is used in the facilities Cooling between roughing and finishing mill cooled to the temperature of the respective temperature area and then finish-rolled ferritically or mixed austenitic-fer ⁇ tically in the finishing mill.With austenitic rolling, the hot strip is heated in facilities for heating between roughing and finishing mill or kept at the same temperature, including austenitic in the
- the known production plants require devices for descaling the starting material before the first stitch and before the finishing train.
- the need to descaling the starting material before the first stitch arises due to the scaling of the surface of the starting material during this
- the production process in the known or proposed production systems is discontinuous or, in the case of welding hot strip to the roughing train, only continuously in the finishing train
- Roll gap lubrication in the stands of the roughing and finishing lines of known production systems can only be used after tapping the starting material or the hot strip in the respective stand, otherwise the gripping condition is not guaranteed.
- the reduction in the friction between the rolling stock and the roll associated with the roll gap lubrication leads to one Reduction of the forming resistance and thereby the rolling force, the rolling moment as well as the required additional power.
- the surface quality of the hot strip is increased.
- these advantages do not arise for the tapping of the hot strip, which after rolling out makes up a considerable part of the length of the hot strip.
- the production systems for the Load condition can be designed without roll gap lubrication
- the object of the inventions is then to create a production plant for the austenitic, the mixed austenitic-fer ⁇ tician and the ferritic rolling of thin hot strip in an endless fully continuous process with which the aforementioned disadvantages and problems are eliminated and on of which all three technologies mentioned above can be realized
- the task is solved with a production plant of the type mentioned at the outset according to the invention in that the strip cast in a thickness of 5 - 18 mm is cooled in a controlled manner under a protective gas atmosphere and the pre-rolled hot strip is optionally cooled in a control device downstream of the rough road, is heated or kept at temperature and the edges of the hot strip are rewarmed
- the production process is specially designed for the rolling of thin casting strip using all three possible technologies, ie austenitic, austenitic-ferritic and ferritic rolling. be produced with a total decrease of at least 65% based on the overall system
- the rolling temperature in the austenite area in the rugged forecourt is controlled by variable cooling of the casting belt in front of the
- carbon steels, low-alloy steels, low-carbon steels and micro-alloyed steels due to a material-dependent decrease of 45 to 70% in the rusty roughing mill in connection with the variably adjustable rolling temperature in the austenitic range and the process itself
- Reshaping subsequent cooling, heating or maintaining the temperature until it enters the multi-grooved finishing line and the initial size of the casting belt is greatly reduced with only one stitch, but at least halved
- the rolling temperature upstream of the multi-stand finishing train through the device arranged behind the roughing street for controllable cooling, heating or holding the The temperature of the hot strip can be selectively adjusted either in the austenitic or ferrite area or in the transition area from austenite to ferrite
- the rolling temperature in the hot strip produces a fine-grain structure of grain size classes 6-10 according to DIN 50601
- the rolling temperature which can be variably adjusted by means of cooling, the material-dependent high decrease of 45 - 70% in the coarse foreroom and the variably controllable cooling, heating or maintaining the temperature of the hot strip, the hot strip is reinstalled before it enters the finishing train and the starting size of the casting belt is strong reduced
- the ferrite endless and the mixed austenitic-ferrite endless fully continuously rolled hot strip will be wound into the bundle in warm-insulated winding machines immediately after emerging from the last stand of the multi-stand finishing train and subjected to slow cooling homogeneous across the bundle width
- the thin casting belt is provided with a start-up piece, it is proposed that the start-up piece pass undeformed in the rolling direction through the open scaffolding of the fore-pass and the multi-stand finishing train and be separated from the rest of the casting line with scissors
- the rolls are set in motion while the open stands are being closed Lubricate the roughing mill and the multi-stand finishing mill on the gaps provided for rolling the required final thickness
- the roll gap lubrication takes place during the entire rolling time, the wear on the work rolls decreases, which improves the thickness and profile over the entire hot strip length and increases the service life of the rolls
- the invention provides that the degree of scaling on the
- the surface of the starting material and the chemical composition of the scale is adjusted by the controllable cooling of the casting belt under a protective gas atmosphere until the first rolling pass
- the invention results in an overall system concept with which a fully continuous endless rolling process can be implemented in an optimal manner, which permits all three possible rolling technologies for the production of hot strip, that is, the austenitic, the mixed austenitic-fer ⁇ tician and the ferritic rolling
- Strip material with small thicknesses, both austenitic and ferritic and mixed austenitic-fer ⁇ tic, with a total decrease of at least 65% based on the overall system, can be produced is shown in the single drawing figure and is described below. It consists of a thin slab caster 12, a first device 2 for cooling the casting belt under protective gas, a coarse Vorstrasse 3, a multi-stand finishing train 5, a second device 4 for cooling, heating or maintaining the temperature of the hot strip between the roughing and finishing train, a pair of scissors 6 for separating the hot strip from bundle to bundle, one Outfeed roller table with facilities 8 for cooling the rolled hot strip and one of the finishing train
- the course of the rolling process begins with the targeted cooling of the solidified casting belt with a thickness of 5 to 18 mm under a controllable protective gas atmosphere, whereby the technologically required parameters, temperature, austenite starting grain size, the
- Degree of scaling and the chemical composition of the scale can be set before the first roll pass
- the starting piece of the thin casting belt passes undeformed through the open scaffolding of the coarse Vorstrasse 3 and the multi-stand finishing train 5 in the rolling direction 1 1 and is separated from the rest of the casting belt with one or more cuts using the scissors 6 arranged after the finishing train.
- the open scaffolding of the coarse Vorstrasse 3 and the multi-stand finishing train 5 is moved to the roll gaps provided for rolling the required final thickness and the piece of hot strip rolled during the closing process is chopped with scissors 6 or coiled with winding machines 7 or 10
- Roll gap lubrication can already be used during the closing of the stands to the roll gaps provided for rolling the required final thickness, since the gripping condition is guaranteed as a result of the steadily increasing decrease up to the end position
- the starting material is rolled endlessly in the rusty Vorstrasse 3 with a material-dependent decrease of 45 to 70% for carbon steels, low-alloy steels, low-carbon and micro-alloyed steels in a horizontal pass in the austenitic temperature range
- the edges of the casting belt are slightly deformed by means of a special compression caliber in a vertical framework flanged in front of the rusty Vor No 3, whereby the casting belt simultaneously runs into the center of the rusty Vorstrasse
