方坯亚包晶钢漏钢原因分析与控制

摘要

Combining the production practice, it analyzed the causes of the breakout of small billets hypo-peritectic steel, formulates the corresponding measures.Through the process parameters optimization such as tundish temperature, casting speed, mould taper, inlet-water temperature and so on, and the leakage frequency has been effectively controlled from 3.2 to 0.25 per thousand tons steel and achieved good effect.%结合生产实践,分析了安钢小方坯亚包晶钢漏钢的原因,制定了相应的措施.通过对亚包晶钢成分、中包温度、拉速、结晶器锥度以及进水温度等工艺参数的优化,实现了小方坯亚包晶钢漏钢次数由之前的3.2次/千吨钢降低到0.25次/千吨钢,取得良好的效果.
