Abstract
The utility model belongs to the measurer that the deformation of steel mill billet caster rigid dummy bar or abrasion are identified, detect, particularly a kind of square billet rigid dummy bar outer arc accuracy detection model, including billet caster rigid dummy bar, its inner arc working face to arc model of strip arc line shaped is engaged with the extrados of rigid dummy bar, radius to arc model inner arc working face is 9 meters, length to arc model is 1 2m, and thickness is 30 40mm, and width is 100 200mm.The utility model is rational in infrastructure, can carry out effective detection according to the working condition of dummy bar, deformation tendency, can solve precision and be forbidden the dummy ingot for causing to can't get into crystallizer or the favorite outer disengagement of strand distraction procedure, the problem of boot failure.
Description
Technical field
The utility model belongs to the amount that the deformation of steel mill billet caster rigid dummy bar or abrasion are identified, detect
Tool, particularly a kind of square billet rigid dummy bar outer arc accuracy detection model.
Background technology
Steel mill billet caster rigid dummy bar is that modern billet continuous casting produces wide variety of part, and Main Function is just
It is the initial stage traction that strand is completed when casting machine is started shooting, subsequent production is carried out continuously.Set according to casting machine technique and structure
Meter feature, dummy bar can have various different arc radius, and the bigger dummy ingot shaft of radius is more long.（Thus cause rod-type design,
The setting of sedan-chair machine pressure is drawn all to affect the change of design parameter.Deformation, tractive force dummy bar, this requires dummy bar accurate
Crystallizer really is penetrated, while can be smoothed after casting machine startup strand is drawn to follow-up throwing and flood dragon to equipment in feeding and throwing
During can be along outer arc direction）, dummy bar is regular in actual production there is following two aspects problem：
Firstth, dummy ingot can't get into mouth under crystallizer copper pipe, and arc deviation is big；
Secondth, dummy bar head is easily disengaged with strand in start process of billet withdrawal, causes throwing to fail.
Analysis reason, the installation accuracy of the cold support dress roller of casting machine two can be corrected by bank model, but rigidity is drawn
Spindle blade is especially for the larger dummy bar of arc radius because of internal and external cambered surface generation after itself " rigidity " feature and long-term use
" crimping " phenomenon, make its arc precision state more difficult in line justification.This is accomplished by periodically to enter rigid dummy bar
Row " arc " accuracy detection, with the working condition of this determination dummy bar.
Utility model content
The purpose of this utility model is to provide a kind of square billet rigid dummy bar outer arc accuracy detection model, and its structure is closed
Reason, can carry out effective detection according to the working condition of dummy bar, deformation tendency, can solve precision and be forbidden the dummy ingot for causing to send
Crystallizer or the favorite outer disengagement of strand distraction procedure, the problem of boot failure are not entered.
What the purpose of this utility model was realized in：A kind of square billet rigid dummy bar outer arc accuracy detection model, including
Billet caster rigid dummy bar, the extrados to its inner arc working face of arc model and rigid dummy bar of strip arc line shaped matches
Close, the radius to arc model inner arc working face is 9 meters, and the length to arc model is 1-2m, and thickness is 30-40mm, and width is
100-200mm。
The characteristics of being difficult to on-line checking for the change of dummy bar arc, makes special measuring tool.Made according to arc radius
Length be 1m-2m duralumin, hard alumin ium alloys to arc model, its working face is in model inner arc side.Offline dummy bar to be checked is placed in a detection
Plane is at free state, manually continuously or intermittently detects the data of diverse location in its extrados with model, reaches and draws
The purpose of spindle blade arc accuracy detection, is that dummy bar reparation or replacing provide foundation.
The utility model is rational in infrastructure, can carry out effective detection according to the working condition of dummy bar, deformation tendency, solves
Precision is forbidden the dummy ingot for causing to can't get into crystallizer or the favorite outer disengagement of strand distraction procedure, the problem of boot failure.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model front view structure
Figure.
Specific embodiment
A kind of square billet rigid dummy bar outer arc accuracy detection model, as shown in figure 1, including billet caster rigid dummy bar
1, its inner arc working face to arc model 2 of strip arc line shaped is engaged with the extrados of rigid dummy bar 1, to the inner arc of arc model 2
The radius of working face is 9 meters, and the length to arc model 2 is 1-2m, and thickness is 30-40mm, and width is 100-200mm.To arc
Fabrication hole 3 is uniformly arranged in the plate face of model 2.Arc model 2 is made up of aluminium alloy.
Claims (3)
