DETECTING MICROPOROSITY DEFECTS IN STEEL CASTINGS BY COMPUTER MODELING OF THE CASTING OPERATION IN ProCAST

摘要

The casting of a large steel globe-cock plug is examined to illustrate the use of computer modeling to find zones where macro- and micro-porosity are concentrated. The article discusses the key aspects of the problem's formulation in ProCAST software, presents modeling results, and compares the defects that are found by modeling with experimental data obtained in a foundry.
