摘　　要：提高连铸坯热装炉温度可以显著降低成本,创造良好的经济效益,限制热装炉温度的主要因素为析出的氮化铝在加热过程中造成的连铸坯表面裂纹。通过分析氮化铝在连铸坯冷却过程中析出行为和钛元素的影响,确定了连铸坯的装炉温度原则。Increasing the temperature of the hot charging Reheating furnaces can significantly reduce the cost and create a good economic benefit. The main factors that limit the hot charging temperature of Al-killed steel are the surface cracks caused by the precipitation of Al N in the heating process. According to the analysis of the precipitation behavior of Al N in continuous casting slabs and discussing the influence of Ti,determined the principle of the charging temperature.
