Abstract：On the basis of analyzing primary process and structure of gray iron braking plate, hydrodynamic software Flow3D was used to simulate the distribution of defect and temperature field in different improved casting systems. According to the simulated results, the merits and faults of all programmers were investigated and the feasible casting system was determined. The results showed that steady flow of molten metal, less spatter and uniform temperature distribution could be achieved and impurity defect mainly distributed in gate riser or nonworking surface when adopting the casting system with unidirectional ingate, which gave the braking plate better quality.
