摘要: 采用三维铸造软件Procast模拟了钢厂1.9 t扁D2钢锭(%:1.40~1.60C、11.00~13.00Cr、0.70~1.20Mo、≤1.10V)浇铸和凝固过程。模拟结果表明,1.9 t模具扁钢的本体凝固时间为64 min,完全凝固时间为83min,与经验公式的计算结果相吻合;钢锭柱状晶厚度为150 mm左右,等轴晶宽度为260 mm左右;1.9 t扁锭内部无缩孔产生、疏松轻微。

Abstract: The casting and solidification process of 1. 9 t slab ingot of steel D2 (% : 1.40 - 1. 60C, 11.00 ~ 13. 00Cr, 0. 70 〜1.20Mo, ≤1.10V) have been simulated by using three-dimension foundry software Procast. Results show that the solidification time of 1.9 t slab ingot body and whole ingot are respectively 64 min and 83 min, it corresponds with calculation results by experience formula; the columnar crystal thickness is about 150 mm and the width of equiaxed crystal zone is about 260 mm; and there is no shrinkage cavity in 1. 9 t slab ingot only with slight porosity.
