Description
Technical field
The utility model relates to continuous casting fields, and it is fan-shaped to specifically refer to a kind of slighter compress for the artificial bulge of slab
Section.
Background technique
In continuous casting, slab centre, often the segregated zone of formation element enrichment, is that the common one kind of slab is macro
Defect center segregation is seen, center segregation is often with center porosity and centre burst.The center segregation of slab once being formed, can not
It is completely eliminated in subsequent handling (such as roll, be heat-treated), and center segregation can severely impact Inner Quality of Billet.
In order to mitigate center segregation, soft reduction technique is applied generating center segregation section (casting blank solidification latter end), that is, is existed
Soon at complete solidification, slab is slightly depressed, mitigates center segregation.When slab enters slighter compress region, due to
Corner has solidified, and resistance of deformation is big compared with centre, causes thickness reduction deformation in width direction uneven.
Existing intentional bulge soft reduction technique be the roll gap on casting direction is arranged to by artificially it is front wide and rear narrow, therefore
Meaning makes casting blank bulging；When slab enters slighter compress region, centre thickness is bigger than border region, and slighter compress roller does not just connect
The corner part solidified completely is touched, thus in the uniform slighter compress of width direction；Though the intentional bulge soft reduction technique is conducive to subtract
Light center segregation, but drafts fixation can not on-line tuning influence Inner Quality of Billet, need to change in continuous casting technique ginseng
When number, depressing position need to be manually adjusted, and flexibility is low.
