Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

The utility model provides one kind and precisely aligns stopper device, referring to Fig.1, including stopper 4, the stopper 4 is hollow, 4 bottom of stopper is equipped with the stopper head 2 for sealing nozzle brick 1 in ladle, adjusts core bar 5 by interspersed at the top of stopper and is fixed on plug In stick.Adjusting core bar can be fixed by its external screw thread and the internal screw thread in 4 screw top hole of stopper, by rotating stopper, be adjusted whole A stopper protrudes into the depth in ladle.The top for adjusting core bar 5 is fixed with 6 one end of crossbeam, and the other end of crossbeam 6 passes through angle tune Section bolt 7 is fixed on cross-brace plate 8, and the bottom of support plate 8 adjusts lifting with by elevating mechanism by guide-localization bar 9 Sliding core pole 11 connects, and referring to Fig. 2, support plate 8 is equipped with 3 mounting holes, is from left to right orderly used to installation and adjustment core bar 5, angle Degree adjusts bolt 7 and guide-localization bar 9, wherein the mounting hole for installing guide-localization bar 9 can installed using slot When 8 position of flexible modulation support plate, the angle of crossbeam 6 is adjusted in conjunction with angle adjustable bolt 7, to realize the accurate of stopper 4 Alignment.Guide-localization bar 9 and sliding core pole equal 11 are interspersed in for being fixed on 10 in the outer tube on the outside of tundish containment wall, described The upper inside wall shape of outer tube 10 is chimeric with guide-localization bar outer wall shape, and four directions design as shown in Figure 1 can be used.

The middle part of the outer tube 10 is equipped with external screw thread, and lift adjustment wire ring 12 is connected to outer tube 10 by its inner screw sheath Middle part is equipped with the shelves 13 for being fixed on the outside of tundish containment wall below lift adjustment wire ring 12.One side shelves 13 and liter On the other hand falling tone section wire ring 12 adjusts wire ring by rotation and lifting and adjusts outer tube for 10 position of outer tube to be fixed Height.

Fig. 1 show using plate stem the case where as lifting device.The bottom end of the plate stem 17 is in a manner of pin shaft and fixation The first fixing piece 20 connection outside containment wall, the rotation fulcrum 16 of plate stem 17 are connected by one end of pin shaft mode and strut, should The other end 15 of strut is connect in a manner of pin shaft with the second fixing piece 14 being fixed on outside containment wall.It, can when pulling spanner downwards Sliding core pole 11 is jacked up, until the external screw thread area of guide-localization bar 9 is detached from the internal threaded regions of outer tube 10, will can entirely be slided Core bar 11 removes outer tube 10, the work such as is replaced, debugged.

The bottom of the bottom of sliding core pole 11 can be arranged damping spring 18, and the upper end of damping spring is connect with sliding core pole, The lower end of damping spring is held on the first fixing piece 20, when stopper decline, reduces stopper head 2 and the mouth of a river by damping spring Shock when brick 1 contacts.Spring-compressed adjusting nut 19, spring can be also set between damping spring 18 and the first fixing piece 20 The external screw thread of compression adjustment nut 19 is matched with the through-hole internal screw thread of the first fixing piece 20, passes through adjustment spring compression adjustment nut The compression degree of damping spring is adjusted on 19 along height.

The case where Fig. 3 show using hollow type hydraulic cylinder as lifting device and installs damping spring.Hollow type is hydraulic Cylinder 21 is located at the lower part of outer tube, is threaded onto outer tube lower end by cylinder body, by the piston rod band for being socketed on sliding core pole 11 Dynamic sliding core pole moves up and down.When the piston rod of hydraulic cylinder retraction, sliding core pole is driven to move upwards, while stopper moves up, Plug hole is opened, the molten steel 3 in tundish, which flows down, to be poured；When hydraulic cylinder stretches out, damping spring 18 is compressed, reduces stopper head and water Shock when mouth brick contact, prevents stopper head from so that sprue gate is not closed completely because of deformation.Hydraulic cylinder moves stopper movement Location control, displacement stroke is accurate, pour steel uniform flow is reasonable, and control adjustment stopper opening degree stablizes liquid level with this, It prevents liquid level fluctuation of molten steel range excessive, causes slag inclusion, so that deoxidation products and non-metallic inclusion is floated, to reach stable Flow control effect.

One kind provided by the utility model precisely aligns stopper device, carries out on the basis of existing stopper lifting device It improves, adjusts stopper center position using angle adjustable bolt, using the length for adjusting core bar adjusting stopper, utilization and outer tube The center of the fixed sliding core pole of chimeric locating rod, realizes precise alignment, is not susceptible to displacement after having the advantages that centering, It is applicable to the tundish of various models, installation and debugging are simple.
