目前,我国机械厂热处理用渗氮箱(罐)一直采用1Cr18Ni9Ti不锈钢板焊接而成。这种渗氮箱易发生老化现象,箱体使用寿命短,工艺不稳定,而且费用较高。近几年来,我校研制成功了搪瓷渗氮箱,这种渗氮箱设计合理,密封性好,改善了劳动条件,特别是搪瓷内壁对氨分解不起催化作用,从而可稳定渗氮工艺,减少氨的消耗量,延长箱体使 At present, China’s machinery plant nitriding tank (tank) has been used 1Cr18Ni9Ti stainless steel welded together. This nitriding box prone to aging phenomenon, the box life is short, the process is not stable, but the higher costs. In recent years, our school successfully developed enamel nitriding box, this nitriding box design is reasonable, good sealing, improved working conditions, especially the enamel wall catalytic decomposition of ammonia can not afford to stabilize the nitriding process, Reduce ammonia consumption, extend the box to make
