摘　　要：黏结问题是通钢FTSC薄板坯连铸生产的主要难题之一,其产生的主要机制是铸坯与结晶器铜板之间的摩擦力增大引起的坯壳断裂。针对通钢现有生产条件,通过对钢水成分、保护渣性能、工艺参数、钢水过热度等进行优化调整,使黏结率得到了有效的控制。The problem of sticking is one of the main challenges of FTSC thin slab continues caster of Tonghua steel, which is caused by the breaking of the slab shell due to the increasing of friction between strand and copper of the mold. On the bases of the processing conditions of Tonghua steel, the composition of molten steel, the performence of fluxes, the parameters of process and the superheat of molten steel were modified. The problem of sticking has been controlled effectively.
