Math Simulation on Casting and Solidifying Process of 1.9 t Slab Ingot of Cold Working Die Steel D2 and Internal Defect Prediction

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 respectiv...

Description
Summary: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.
