摘　　要：对生产数据进行分析,认为钢水成分、拉速和结晶器液面波动等是造成连铸坯表面纵裂的主要原因。为此,根据结晶器专家系统进行可视化的生产指导,从钢种成分控制、生产操作等方面提出了改进措施,减少了连铸板坯表面纵裂的产生。The composition of molten steel, east speed and mould level changing are thought to be main reasons of causing surface longitudinal cracks by analyzing producing data. Then according to the mould expert, tile visible production instruction is carried on, and some performance measures are put forwarded from controlling composition of molten steel and production operating, etc., so the surface longitudinal cracks are reduced.
