摘　　要：对舞钢板坯连铸机二冷区的铸坯表面温度进行了测定。分析了冷却水分布对板坯表面纵向和横向温度分布的影响和表面温度分布对铸坯表面横裂纹的影响。指出 16The slab surface temperature has been measured in second cooling zone of slab caster at Wuyang Iron and Steel Co., Ltd.. The effect of second cooling water distribution of surface temperature distribution has been analyzed. The effect of surface temperature on surface cross cracks has been analyzed in detail. It is pointed out that the important reason for cross crack formation is that 16Mn slab edge temperature falls into the third brittleness zone.
