通过对邯钢三炼钢厂板坯连铸生产高强度船板用等铌微合金钢,铸坯发生表面横裂纹的机理分析,讨论了铸坯表面横裂纹产生的影响因素,并提出了连铸解决含铌钢表面横裂纹的有效措施。
Through the analysis of the mechanism of surface transverse cracks on the surface of niobium microalloyed steel and slab produced by slab continuous casting in the third steelmaking plant of Handan Iron and Steel Co., Ltd., the influencing factors of the transverse cracks on slab surface are discussed. Casting to solve the surface of niobium steel transverse cracks in the effective measures.
