摘　　要：通过不同结晶器漏斗及窄边形状和不同的保护渣的对比试验,在平整工序逐卷检验热轧板卷纵裂缺陷,确定了控制低碳钢表面裂纹缺陷的最佳工艺技术路线。在此基础上,研究了薄板坯纵裂的发生机制和漏斗结晶器的连铸工艺特性,为控制薄板坯纵裂提供依据。According to the contrast test of different funnel mould, different mould narrow-face shape and different mould powder, and inspecting longitudinal cracks on hot-rolling coil, the best technological route for controlling surface crack defects of low carbon steel was determined. On this basis, the occurrence mechanism of longitudinal crack on thin slab and the process characteristics of funnel mould were analyzed, providing the basis of controlling longitudinal crack on thin slab.
