摘要
本文通过对天津钢管公司圆坯连铸机生产数据的分析,讨论了二冷水嘴喷淋特性、浇注温度和钢水成份等因素同铸坯表面裂纹之间的关系,归纳了导致该铸机于1993年5～7月间在铸坯表面持续、大量地出现裂纹的主要原因,并提出了解决铸坯裂纹问题的若干措施。
By analysing the production data from the round billet CC at Tianjin Steel Tube Co. ,this article discussed the relation between the nozzle properties in spray zone, the temperatrue and composition of liquid steel for casting etc. and the surface crack of round billets and pointed out the main reason causing these surface cracks which happened largely and continuously during May to Jul 1993 and also proposed some measures to overcome them.
