Abstract:Based on the solidification & heat-transfer mathematical model of slab continuous casting coupled with the multi-alloy microseg- regation model and the tracking method with slice elements in constant interval, the CISDI dynamic secondary cooling software platform has been developed, which comprises oftwo control modes, via., the effective casting speed ofsecondary cooling zones, and the targeted surface temperature curve of slab, as for them, the former one takes full considerations about the cooling history of slab, and the latter one takes emphasis on the reasonable control of slab surface temperature along casting direction, both can be chosen to apply in actual casting process conveniently and flexibly. This technology has abundant control function, all-around safety mechanism, stable running system, friendly operating interface, and good industrial adaptability, which has been put into use successfully on the No. 1 slab caster of Chongqing Steel Plant, and has obtained good metallurgical effects for control of slab surface/internal quality. So, it has great industrial practical value, and can be put into practice widely.
Keywords:slab continuous casting  heat-transfer & solidification  dynamic secondary cooling  industrial application
