Abstract
The invention discloses a large-rolling reduction cast flow guide device of a continuous casting machine. The large-rolling reduction cast flow guide device of the continuous casting machine is characterized in that an upper framework and a lower framework are fastened by a clamping hydraulic cylinder, and a lead rail is arranged at the inner side of each of the upper framework and lower framework. An upper working roll is arranged below an upper lifting beam, the upper lifting beam is hinged to the upper framework through a reduction hydraulic cylinder, there is a sliding fit clearance between the upper lifting beam and the upper lead rail, and a position sensor is arranged in the reduction hydraulic cylinder. A lower working roll is arranged above a lower lifting beam, the lower lifting beam is hinged to the lower framework through a pressurization hydraulic cylinder, there is a sliding fit clearance between the lower lifting beam and the lower lead rail, and a position sensor is arranged in the pressurization hydraulic cylinder. A transmission device is connected with the upper working roll and lower working roll. The large-rolling reduction cast flow guide device of the continuous casting machine organically combines a cast flow guide section of the prior art with a rolling mill into a single unit, the structure is compact, the heart of a cast blank is loosened and compacted, and therefore, a normal casting machine can produce a super-thick steel plate with excellent quality, the thick steel plate production technology process is changed, the medium plate rolling pass is reduced, and the medium plate production cost is lowered.
Description
Technical field the invention belongs to conticaster technical field, particularly medium slab caster group.
Background technology current steel mill medium slab caster produce casting blank inner organization shrinkage cavity, the defect such as loose, affect the quality of strand, must at jobbing sheet-rolling mill heavy reduction, through multi-pass rolling, defects such as organizing shrinkage cavity, loosen could be eliminated, produce high-quality sheet material, but this can make steel plate thickness specification quantity reduce.If through the continuous casting billet of excessive pressure casting stream device rolling, be rolled in casting blank solidification end strand core mushy zone, then can seam strand core, such strand carries out few passes just can produce qualified middle plate, the quantity of steel plate thickness specification increases, and saves the energy.
Summary of the invention is in order to overcome the defect existed in the common casting machine of prior art, grasp the mechanical performance improving continuous casting billet, improve Plate Rolled quality, plate thickness specification in increase, reduce the object of rolling pass economize energy, the present invention proposes following technical scheme: a kind of conticaster large pressure casting flow guide device, is characterized in that: it is fastening that the upper frame be arranged symmetrically with up and down and underframe are clamped hydraulic cylinder, be provided with upper rail inside upper frame, inside underframe, be provided with lower guideway.Top working roll is arranged on below lift beam, and upper lift beam is hinged on upper frame by hydraulic cylinder for reduction system, is the gap that is slidably matched, is provided with position sensor in hydraulic cylinder for reduction system between upper lift beam and upper rail.Bottom working roll is arranged on above lower lift beam, and lower lift beam is hinged on underframe by pressing hydraulic cylinder, lower lift beam (and be also the gap that is slidably matched between lower guideway, press in hydraulic cylinder and be also provided with position sensor.Transmission device is connected with top working roll and bottom working roll respectively.In the below of upper lift beam, top backing up roll is installed, in lower lift beam, also lower support roll is installed.
Adopt the present invention of technique scheme casting stream guide section of the prior art and rolling function to be combined as a whole, both achieved continuous casting flow guider and there is interchangeability, there is again milling train function.One time drafts is 10% of slab thickness, and the internal rarefaction of strand is organized compacting, makes conventional casting machine can produce the excellent super-thick steel plate of internal soundness.This casting flow guide device is reasonable in design, compact conformation, and improve the mechanical performance of continuous casting billet, the continuous casting billet of extrusion can meet the strength character requirement of steel plate, thus changes the steel plate technological process of production, reduces the production cost of steel plate.
Accompanying drawing illustrates that the invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is conticaster of the present invention large pressure casting flow guide device front view;
Fig. 2 is the cross-sectional schematic along A-A line in Fig. 1;
Fig. 3 be prior art common casting machine casting before and casting after working roll and strand view;
Fig. 4 is working roll and strand view before conticaster of the present invention large pressure casting flow guide device rolls and after casting.
In figure: 1, upper frame, 2, underframe, 3, top working roll, 4, bottom working roll, 5, compression hydraulic cylinder, 6, transmission device, 7, hydraulic cylinder for reduction system, 8, press hydraulic cylinder, 9, upper lift beam, 10, lower lift beam, 11, top backing up roll, 12, lower support roll, 13, strand, 14, upper rail, 15, lower guideway (not shown in FIG., it is corresponding up and down with upper rail position).
Specific embodiments of the invention shown in detailed description of the invention accompanying drawing.Its underframe 2 can be installed on basis, former continuous casting workshop fan-shaped section horizontal segment district, can realize and factory's original equipment rapid interchangeable.
Upper frame 1 and underframe 2 that it is arranged symmetrically with up and down are clamped hydraulic cylinder 5 and are tightened to one.Be provided with upper rail 14 inside upper frame 1, inside underframe 2, be provided with lower guideway 15.Top working roll 3 is arranged on below lift beam 9, and upper lift beam 9 is hinged on upper frame 1 by hydraulic cylinder for reduction system 7, is the gap that is slidably matched between upper lift beam 9 and upper rail 14.Position sensor is provided with in hydraulic cylinder for reduction system 7.Bottom working roll 4 is arranged on above lower lift beam 10, and lower lift beam 10 is hinged on underframe 2 by pressing hydraulic cylinder 8, is also the gap that is slidably matched between lower lift beam 10 and lower guideway 15.Press in hydraulic cylinder 8 and be also provided with position sensor.In the below of upper lift beam 9, top backing up roll 11 is installed, in described lower lift beam 10, lower support roll 12 is also installed.The top working roll 3 be installed in upper frame 1 moves up and down and is installed on bottom working roll 4 in underframe 2 and moves up and down, and can press to the strand 13 entirely do not solidified by casting flow guide device simultaneously.Top backing up roll 11, the quantity of lower support roll 12 is the multiple of mounted in pairs.Hydraulic cylinder for reduction system 7 is all equipped with sensor and carries out position control with pressing in hydraulic cylinder 8, when the strand 13 being in solidification end is positioned at large pressure casting stream guide range, top working roll 3 and bottom working roll 4 carry out heavy reduction pressure to strand 13 simultaneously, and press drafts feeding, transmission device 6 respectively transmission top working roll 3 and bottom working roll 4 carries out casting, overall reduction is about 10% of slab thickness, the core open texture compacting of strand.In Fig. 3, Fig. 4 of accompanying drawing, M represents casting flow path direction, and P represents the pressing direction of upper and lower working roll.The present invention, with casting stream guide function and milling train function, can make conventional casting machine produce the excellent super-thick steel plate of internal soundness, changes the steel plate technological process of production, reduces costs raising quality.
