| Abstract: | In the paper,the shrinkage and porosity of the WEIR Pump steel casting was studied by CAD/CAE,then a optimizing foundry technology was proposed.By 3D modeling software,the body of the casting was divided into some parts,and each modulus of the parts was calculated by the 3D software.Then according to the modulus distribution in the casting,the compensation regions were divided and every riser's size was calculated by perimeter quotient in order to increase their yield.The new technology was verified by the simulation software FT-STAR.The computed result shows that the improving technology which removes a large parts of shrinkage and the porosity in key location of the casting is reasonable. |
