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.
