Casting Process Design and Numerical Simulation of Cast Iron Tile Body of Bearing
The traditional casting process of tile body was designed,then the process was simulated by Viewcast software.The simulation results show that the first solidification regions are in both sides of tile body and the thin part of the ring region,the upper and lower of cavity and the tendons finally solidify,so the final solidification regions have shrinkage,porosity and other defects;in order to remove the defects,two pressure risers and one side riser are set up at the corresponding position of the title body,but there are still shrinkages and other defects in the casting,then cold chillers are placed in the corresponding position of the casting.In the end,the eligible castings are gained.
