摘　　要：采用铸造模拟软件对生产过程中易出现缩孔、疏松的15 t钢锭进行了凝固模拟分析,预测了缩孔、疏松的位置及大小,模拟结果与实际解剖结果一致。在凝固模拟的基础上,设计了一系列新的钢锭模,根据模拟结果较好的钢锭模进行了模具制作,在生产中,新钢锭模取得了良好的效果。A 15 t steel ingot, in which shrinkage and porosity were often found during production, was analyzed by using of casting simulation sottware. Position and size of the shrinkage and porosity were predicted, which agreed with the actual dissection experiment very well. On the basis of simulation results, a series of mold schemes were designed and new mold was fabricated based on the better simulation result. The new mold performed well in production.
