冒口高度对钢锭内部品质影响的模拟分析
摘要
采用铸造模拟分析软件对不同冒口高度的12t钢锭进行了计算机模拟分析
并预测了钢锭缩孔缺陷的分布。计算结果发现原来生产过程中冒口高度下的缩孔深度较大
将模拟结果与试验结果进行了对比
两者相符。在此基础上
用计算机模拟优化了冒口高度并进行试验验证。模拟与试验结果表明
优化后的冒口高度可以消除缩孔缺陷
提高了钢锭品质和利用率。
Abstract
Filling process of 12tsteel ingots with different riser height was simulated by a software to predict the distribution of shrinkage cavity.The results show that shrinkage cavity in the precedent ingots is much deeper
which is well agreement with validation experiments.Therefore
the riser height was optimized by solidification simulation and validated by experiments.The results indicate that the optimized riser height can eliminate the shrinkage cavity
and enhance the steel ingots′quality and utilization.
