Application of the Dynamic Soft-Reduction Technology on the No.4 Slab Continuous Caster of Bayi Steel
The revamping & upgrading work has been done smoothly for the existing soft-reduction system of the No.4 slab continuous caster in Bayi steel, as a result, all the segments (include both arc segments and level segments) now have the dynamic soft-reduction function, which have been put into the industrial application successfully. Through the production practice, it can been seen that, after the revamping project, the dynamic soft-reduction function could be applied normally both in the arc segments and in the level segments for the No.4 slab caster, the whole soft-reduction process has been conducted steady and smoothly, the precision of roll gap control is good, the L2 model always makes a exact trace for the casting process and has the advanced algorithm, the L1 program has the reasonable control function and the reliable execution. When the soft-reduction action was executed in the unbending segment (Seg.7), there was no internal crack taking place for all the as-cast slab, and the internal quality of slab such as center segregation was improved obviously, which had shown the metallurgical effect of the dynamic soft-reduction technology fully.
