摘要
采用ＺＧ３５Ｃｒ２４Ｎｉ７ＳｉＮ耐热不锈钢铸造的炼镁还原罐能保持高温（１１８０℃～１２００℃）工作环境下的机械强度．炼镁还原罐由离心铸造的罐身与砂型铸造的罐帽焊接而成．在罐身离心铸造工艺中，应注意防止裂纹、冷隔、铁豆、凸凹不平、罐身内表面有夹渣和气孔等问题的产生．

magnesium\|smelting reducing pot that is casted with ZG35Cr24Ni7SiN heat\|resisting stainless
steel can keep the mechanical hardness in the high temperature(11801200).The
magnesium\|smelting reducing pot consists of the centrifugal cast pot body welding with sand cast
pot's cap.In the centrifugal casting process,the worker must avoid of some flaws,such as
crackle,cold partition,unmelting particle,unplainface,dregs and gas hole and so
on.
