摘要
依据湘钢现场条件，建立了连铸方坯凝固传热数学模型，分析了过热度、拉坯速度、二冷水量对高碳钢方坯凝固过程的影响，确立了二次冷却与高碳钢二次枝晶间距的关系式，提出了改善高碳钢方坯连铸中心缩孔的途径．
A mathematical model of solidification and heat transfer for continuous casting billets (150 mm×150 mm, 240 mm×240 mm) is established accroding to the conditions of industrial production. The effects of superheat, casting speed, secondary cooling on the billet solidification process are analyzed, and the relation of secondary cooling with secondary dendrit spacing is obtained. Proposals to reduce central cavity in high carbon steel billets are made.
