Abstract：
ProCAST software was used to simulate the mold filling and solidification of large cast steel support, and the
influence of the number and position of riser and chiller on the distribution of shrinkage cavity and porosity was analyzed.
Through the simulation results, the bottom injection casting process is optimized to gradually transfer the shrinkage cavity
and porosity defects from the casting to the riser, and finally the shrinkage cavity rate is reduced to the minimum, so as to
ensure the compactness of the casting metal and obtain high-quality casting.
