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 16 Mn钢板坯表面边部温度落入钢的第三脆性区是造成表面边部横裂纹的一个重要原因
The surface temperature of slab in secondary cooling zone of Wugang slab caster was measured. The influence of cooling water distribution on the longitudinal and transverse temperature distribution of slab surface and the influence of surface temperature distribution on transverse crack of slab surface were analyzed. It is pointed out that the temperature of the edge surface of the 16 Mn steel slab falls into the third brittle zone of the steel, which is an important reason for the lateral crack on the surface edge
