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.
