Abstract
The utility model belongs to the improvement, especially a modified continuous casting slab tail base capping device of steel mill continuous slab casting slab tail base capping device structure, including being located the continuous casting tail base that the crystallizer top has rectangle tail base shell, the structure that continuous casting tail base binds the ware is horizontal board constitution T shape backup pad at the tip rigid coupling of vertical board, wherein the both ends of horizontal board and the one end of vertical board are setting up perpendicular decurrent roof respectively, set up the hangers that has the jack on the centrobaric vertical board top surface of T shape backup pad, the roof at the horizontal board both ends of T shape backup pad cooperates with the symmetrical wide facial features of continuous casting tail base shell respectively, the roof of vertical board tip cooperatees with the leptoprosopy of continuous casting billet base shell. The utility model discloses rational in infrastructure, facilitate the use, can reduce the deflection of the narrow dough shell of tail base, can prevent the casting blank in the molten steel extruded, the safety of staff and equipment, the job stabilization nature and the operation rate of improvement conticaster are guaranteed to the reduction accident.
Description
Technical field
The utility model belongs to the bind continuous casting steel billet tail base of improvement, particularly a kind of improvement of apparatus structure of steel mill sheet billet continuous casting slab tail base and to bind device.
Background technology
Continuous casting tundish has certain service time, and therefore, conticaster needs timing to change tundish.During replacing tundish, conticaster must be shut down; because continuous casting billet afterbody does not have the pressure of molten steel during shutdown; base shell is subject to crystallizer cooling after-contraction; the molten steel that inside still can not solidified is extruded; the molten steel extruded flows in continuous casting machine fan-shaped segment; easily cause continuous casting billet and the adhesion of fan-shaped section roller and draw motionless, and easily damaging fan-shaped section roller, adverse effect is caused to continuous casting machine precision.Therefore need to place at tail base the device that binds after conticaster is shut down, effect is supported by base shell when tail base, makes both sides casting blank shell keep original shape, and the inner molten steel of strand can not be extruded, thus pulls out strand smoothly.Originally the device that binds of use uses Plate Welding, tail base two wide faces can only be supported, but cannot prevent the contraction of crystallizer leptoprosopy base shell during use.
During slab CC tundish quick change, tail base stops the longer time in crystallizer, in fan-shaped section, molten steel can shrink because solidifying, tail base part because of without molten steel static pressure and lack molten steel supplement reason shrink, base shell becomes peel away copper coin state from being close to crystallizer copper board status, further indent occurs.
Occur to carry out tundish quick change processing ease in such cases and following accident occur:
1, tundish quick change process generation bleed-out.
2, join position and ooze steel, occur the cold steel burr of reversal of the natural order of things, in strand downdraw process, hang bad sufficient roller.
3, the bonding cold steel of the section of leading roll surface that steel causes is oozed.
Above accident is pernicious production accident, loses huge, converter, conticaster off-time more than 12 hours, and fan-shaped section consumption is large, and during accident settlement, the working environment of workers is severe.
Utility model content
The purpose of this utility model is to provide a kind of continuous casting steel billet tail base of improvement to bind device, it is rational in infrastructure, easy to use, the deflection of tail base leptoprosopy base shell can be reduced, molten steel in strand can be prevented to be extruded, minimizing accident, ensures the safety of staff and equipment, improves job stability and the operating rate of conticaster.
The purpose of this utility model is achieved in that a kind of continuous casting steel billet tail base of improvement binds device, comprise and be positioned at the continuous casting tail billet that crystallizer inner top has rectangle tail base base shell, the bind structure of device of continuous casting tail billet is that affixed transverse plate forms T-shaped gripper shoe in the end of longitudinal plate, wherein the two ends of transverse plate and one end of longitudinal plate arrange top board vertically downward respectively, longitudinal plate top surface of T-shaped gripper shoe center of gravity arranges the hangers with jack, the top board at T-shaped gripper shoe transverse plate two ends matches with the wide face of continuous casting tail billet base shell symmetry respectively, longitudinal top board of plate end matches with the leptoprosopy of solidification shell.
Main improvement content is as follows:
1, on original device architecture basics that binds, increase the supporting structure of leptoprosopy, use Plate Welding, during use, the part newly increased is withstood on the base shell of crystallizer leptoprosopy, put into crystallizer, thus the base shell of wide for crystallizer and leptoprosopy can be supported, prevent deflection excessive, ensure production safety.Both can meet the requirement of tundish quick change, the amount of contraction that tail base is less can have been ensured again.
The utility model is rational in infrastructure, easy to use, decreases the deflection of tail base leptoprosopy base shell, prevents molten steel in strand to be extruded, decrease accident, ensure that the safety of staff and equipment, improve job stability and the operating rate of conticaster.
Accompanying drawing explanation
Be further described the utility model below in conjunction with accompanying drawing, Fig. 1 is perspective view of the present utility model, and Fig. 2 is the utility model using state schematic diagram.
Detailed description of the invention
A kind of continuous casting steel billet tail base of improvement binds device, as Fig. 1, shown in Fig. 2, comprise and be positioned at the continuous casting tail billet that crystallizer inner top has rectangle tail base base shell, the bind structure of device of continuous casting tail billet is that affixed transverse plate 2 forms T-shaped gripper shoe in the end of longitudinal plate 1, wherein the two ends of transverse plate 2 and one end of longitudinal plate 1 arrange top board 3 vertically downward respectively, longitudinal plate 1 end face of T-shaped gripper shoe center of gravity arranges the hangers 4 with jack, the top board 3 at T-shaped gripper shoe transverse plate 2 two ends matches with the wide face of continuous casting tail billet base shell symmetry respectively, the top board 3 of longitudinal plate 1 end matches with the leptoprosopy of solidification shell.L shape hand matches the bind jack of device hangers 4 of the bending bar of 5 lower ends and continuous casting tail billet.
Claims (2)
1. the continuous casting steel billet tail base improved binds device, comprise and be positioned at the continuous casting tail billet that crystallizer inner top has rectangle tail base base shell, it is characterized in that: the bind structure of device of continuous casting tail billet is that affixed transverse plate (2) forms T-shaped gripper shoe in the end of longitudinal plate (1), wherein the two ends of transverse plate (2) and one end of longitudinal plate (1) arrange top board vertically downward (3) respectively, longitudinal plate (1) end face of T-shaped gripper shoe center of gravity arranges the hangers (4) with jack, the top board (3) at T-shaped gripper shoe transverse plate (2) two ends matches with the wide face of continuous casting tail billet base shell symmetry respectively, the top board (3) of longitudinal plate (1) end matches with the leptoprosopy of solidification shell.
