The objective of this project is to fix bugs that were found on the surface of the work piece bearing shirts in experiments to study the casting process used to make the current bearing shirt. Study of the characteristics of the defect found. Measuring work piece to simulate 3D and simulation of casting of shirts bearing with ProCAST from project to study the effect of volumetric shrinkage (Shrinkage cavity) on the surface of metal solidification of water analysis and water-filled metal work pieces, shirts bearing temperature, pouring the casting suite.1357 .° c Hot metal can fulfill work effectively. Without the bug on a shirt bearing the shape of a cone-shaped riser, using a 30 degree angle, height 156 mm riser straight cylinder of the factory is to increase the height of the riser could not reduce the volumetric shrinkage on the surface of the workpiece.
