摘要
本文从二炼钢厂4#（板坯）连铸机控制内裂的实践，对板坯连铸机出现内裂的原因和控制措施进行探讨，影响板坯内裂的主要因素为铸机设备控制精度、拉速控制、钢水成分和浇铸温度等，提出了降低板坯内裂的措施。
This article from No2 steelmaking plant of 4# （slab） practice of continuous casting machine control internal crack, analyze the causes and control measures of internal crack of slab continuous casting machine, the main influence factors of internal cracks in slab casting machine for control precision, tension equipment of speed control, the composition of molten steel and casting temperature etc, put forward to reduce the internal cracks in slab measures.
