厚板坯连铸二冷凝固传热模型的研究与应用

Study and Application of Solidification and Heat Transfer Models for Heavy Slab in Continuous Casting Second Cooling Zone

以鞍钢厚板坯连铸机为目标机型,按照传热学理论建立连铸二冷凝固传热数学模型。应用此模型对X65管线钢和船板钢的连铸过程进行仿真模拟,模拟结果同实测值基本吻合,验证了模型的可靠性。

Taking Angang heavy slab continuous caster as the target machine, solidification and heat transfer mathematic models for continuous casting second cooling zone are established according to heat transfer theory. The courses of continuous casting X65 pipeline steel and ship plate steel are simulated by the models. The results are nearly accordant with the measured ones and the models are proved reliable.
