板坯连铸二冷区凝固传热过程与控制

Solidification Heat Transfer Process and Control for Secondary Cooling Zone of Slab Casting

摘要: 依据安钢板坯连铸机的具体条件,建立了连铸板坯凝固传热数学模型,实现了随铸坯钢种、断面尺寸及拉速变化对各回路水量连续实时控制.经现场应用表明,利用配水模型所制定的二冷配水制度是合理的,效果良好.

Abstract: A mathematical model of solidification and heat transfer for Continuous Casting slab is established on the basis of slab caster of Anyang iron & Steel Company. According to the steel grades,the slab section sizes and the casting speed,the control model can adjust secondary spray cooling zone water flow rates.The production application has verified that the water flow for secondary cooling is suitable and the quality of casting slab is good.
