Abstract：
The slag inclusion defects often occur in the process of silver alloy bimetal sealing ring casting production was studied. By controlling induction heating process, slag inclusion defect can be reduced. The castings with good microstructure and physical and chemical properties were prepared by induction coil heating and water-cooling process. The results show that the slag inclusion defect parts at least one of the best technological parameters for induction heating temperature is 815±5 ℃, the induced voltage is 350±10 V;The optimum position and method of manual stirring are obtained by using viscosity theory. Under the premise of ensuring the induction heating temperature, the induction frequency should be reduced to make the flux float more easily to achieve the goal of reducing slag inclusion defects.
