Abstract：
According to the structural characteristics of crawler plate casting,the casting process design and optimization were carried out.NX software parts shall be used to conduct solid molding of the strap plate,and the filling and solidification process of the casting shall be simulated by Yunfeng CAE software.The results show that the filling mode of metal liquid in the initial single spout and single riser scheme is easy to cause the air entrapment and slag inclusion defects at both ends of the track plate.At the same time,due to the insufficient shrinkage of single riser,the defect of the strap plate is easily gathered in the inner part.By increasing the number of inner runner and improving feeding measures,the filling process is more uniform and stable,the solidification process is more orderly,and the casting defect is effectively controlled.The optimized casting process is used to produce crawler plate,which reduced the porosity and slag inclusion defects of crawler plate casting,and verified the correctness of the simulation results.
