Cov khoom siv txheej hmoov txheej nyob rau hauv kev tsim khoom tau los cuam tshuam nrog av nkos thiab dej txhua hnub. Ib qho ntxiv, cov khoom xyaw ntawm qee cov khoom xyaw yog cov xeb zoo, uas tuaj yeem ua rau yooj yim ua rau muaj cov khoom siv. Hauv qab no peb yuav qhia ntau yam anti - xeb txoj kev.
1. Tso cov sulfides rau hauv cov ntsev tsis zoo, cov ntsev, tshuaj ntsuab hauv qab no yog qhov sib piv hauv qab no 600 ° ntawm cov khoom siv xim. cov ntaub ntawv txheej, uas txhim kho cov coj tsis kam ntawm ib feem.
2. Qhov no yog ib txoj kev quenching thiab hardening tsuas yog cov txheej txheem ntawm cov tawv nqaij siab tam sim no los ntawm cov txheej txheej ua tiav hauv cov khoom siv siab (ntau zaus tuaj yeem siv los ua kom muaj kev puas tsuaj Kuj.
3. Use an oxygen-acetylene flame to quickly heat the surface layer of the coating equipment to the quenching temperature, and then quench, and the surface will transform and harden.
