Optimization of pouring process for Wheel Castings

It can be seen from the analysis that there is no liquid metal feeding at the center of the wheel due to the early solidification around the wheel, resulting in shrinkage porosity and shrinkage defects. In order to solve the problem that molten metal cannot be fed in time,...
