Quenching txheej txheem kev txawj ntawm kev kub ceev quenching tshuab

1. Ntxiv ntsev rau hauv dej tuaj yeem ua kom txias dua ob npaug: qhov txias ntawm cov dej ntsev quenching yog ceev, thiab tsis muaj qhov tshwm sim ntawm quenching tawg thiab tsis sib xws. Nws tuaj yeem hu ua qhov zoo tshaj plaws coolant rau quenching. Qhov feem ntawm ntsev ntxiv yog nyiam dua 10% los ntawm qhov hnyav.

2. Cov impurities nyob rau hauv cov dej yog tsim nyog raws li quenching kua tshaj li cov dej ntshiab: ntxiv cov khoom hais rau cov dej yuav pab tau ntxuav lub nto ntawm lub workpiece, rhuav tshem cov nyhuv ntawm vapor zaj duab xis, ua rau kom tus nqi cua txias, thiab tiv thaiv qhov tshwm sim ntawm lub workpiece. quenching chaw. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau siv cov cuab yeej quenching ntawm cov dej sib xyaw es tsis txhob siv cov dej ntshiab rau kev kho quenching.

3. Cov polymer tuaj yeem tov nrog dej los tsim cov dej-soluble quenching kua: cov polymer quenching kua tuaj yeem npaj tau raws li qib dej ntxiv rau cov kua quenching nrog cov cua txias ntawm dej mus rau roj, uas yooj yim heev, thiab tsis muaj hluav taws kub, muaj kuab paug thiab lwm yam.
