Abstract

The presented paper deals with a numerical simulation of casting and solidification of a 65-ton ingot made of 25CrMo4 low-alloy chrome-molybdenum steel. The aim was to focus on the assessment of steel melt flow, the risk of formation of microporosity and segregation according to Niyama or Suzuki criteria respectively, solidification. The numerical simulation was done for parametric analysis of solidification process in casting based on boundary conditions. Correctly set values of casting parameters like casting speed, casting temperature of steel, H/D ingot ratio are the essential precondition to minimize the defects of steel ingots.

Keywords: Numerical simulation, THERCAST software, steel ingot, casting, solidification
