摘要
通过对天铁炼钢厂0#板坯连铸机现场数据的跟踪分析,对连铸板坯中间裂纹的形成原因和影响因素进行分析和探讨,认为铸机的设备状况是影响中间裂纹的首要和关键因素,钢中硫含量、钢水过热度和拉速也是中间裂纹产生和扩展的影响因素,并据此提出了减少中间裂纹的改进措施。
By tracking and analyzing the field data of Slab Caster 0, Steel -making Plant, TIANTIE, the author analyzes and discusses the causes and affecting factors of slab central crack formation and deems that the equipment condition of the caster is the prime and critical factor. Sulfur content, liquid steel superheat and casting speed are the affecting factors of central crack formation and propagation. On the basis of the above, the author proposes the improvement measures relieving central crack.
