用于镁还原罐的新型耐热合金及制作工艺

New Heat-resistant Alloy and Production Process Used for Mg Reduction Pot

以ZG30Cr24Ni7废钢为基本原料,合理加入氮化铬铁(26%～28%铬,0.20%～0.40%碳,6%～8%镍,1.0%～2.0%硅,0.20%～0.35%氮,0.20%～1.6%锰,0.2%～0.35%稀土),熔炼过程采用超声波处理,制得一种新型耐热合金。以此合金所制作的炼镁还原罐,采用新型结构,对筒体和球形端底表面进行热浸渗铝,其使用寿命达到4个月以上,具有良好的经济效益。

Taking ZG30Cr24Ni7 scrap steel as basic raw material, then nitrogen ferrochrome （26%-28%chrome; 0.20% - 0.40% carbon; 6% - 8% nickel; 1.0% - 2.0% silicon; 0.20% - 0.35% nitrogen; 0.20% - 1.6% manganese; 0.2%-0.35% tombarthite） were added. A new type of heat resistant alloy can be obtained by ultrasonic treatment technique alloying in melting process. The refined magnesium reduction pot is made by the alloy, taking a new type of structure, using hot dipping aluminizing for the cylinder body and spherical bottom surface. The service life of the pot is up to more than four months, which has good economic efficiency.
