摘要
针对研究现场3号连铸机出现的结晶器钢水液面波动的问题,通过统计分析方法,研究了钢种、碳含量以及二冷制度与结晶器液面波动现象发生的关系。得到如下结果：易发生波动的钢种为S275J0（HB）、WL590、X52（PJ）、ASTM65、B（H1）和X52（BG）;易发生波动的钢水[C]质量分数的危险区为0.075%～0.095%;较优的二冷制度为包晶和中碳。
According to the mold level fluctuation phenomenon appeared on the No.3 continuous caster at the steelmaking plant research field, the effects of factors such as steel grades, carbon content and secondary cooling system on the mold level fluctuation were investigated through statistical analysis method. The results show that the steel grades those are easy to fluctuation are S275J0（HB）, WL590, X52（PJ）, ASTM65, B（H1） and X52（BG）. In addition, the danger interval of carbon content is 0.075%-0.095%, the superior secondary cooling systems are Peri and Med C.
