Green shell is set to be cohered with copper coin.
There is scholar to propose to use convex crystallizer, convex crystallizer is 96 ° in top angle, and it is more steady mutually to pass through face, to changing
Kind corner meniscus performance is favourable, and this kind of crystallizer cooling is uniform, can reduce air gap, can prevent bleed-out and face crack.Someone
Propose to adjust method reduction casting blank off-square, bleed-out that crystallizer water is stitched according to continuous casting different phase.By the both sides that section is led in branch
Special bleed-out guard assembly is installed, the splash face for spilling molten steel, protection lower section fan are reduced by the protective effect of these components
Oil pipe, oil grease tube, the water pipe of shape section and both sides etc. be not contaminated, reduces the loss of equipment, improves the processing speed of accident.This
A little measures can to a certain extent reduce the generation of bleed-out, but bleed-out is also subject to superheat of liquid steel, carbon content in steel, sulfur content, leaching
Enter formula mouth of a river type, misoperation, the influence of the pulling rate change factor such as greatly still has the danger of bleed-out generation, using breakout prediction
System can make early warning, therefore the process units that exploitation is combined with steel leakage prediction system to bleed-out, once there is bleed-out
Can in time prevent and be very important.
The content of the invention
To overcome the deficiencies in the prior art, the purpose of this utility model to be to provide a kind of production of efficient control continuous casting bleed-out
Device, coordinates with forecast system, and continuous casting bleed-out is controlled using direct current and magnetic field force, and equipment is simple, reduces the incidence of bleed-out,
