Cov ntsiab lus ntawm kev suav nrog yog ze ze rau cov ntsiab lus oxygen hauv cov hlau. Qhov siab dua cov ntsiab lus ntawm cov pa oxygen, qhov ntau ntxiv thiab lub neej ua haujlwm luv dua.
Qhov loj dua qhov loj me me thiab tsis sib npaug ntawm kev suav nrog thiab carbides, lawv lub neej kev pabcuam yuav luv dua. Lawv qhov loj me thiab kev faib tawm yog ze rau cov txheej txheem smelting thiab smelting zoo siv. Cov txheej txheem tseem ceeb rau kev tsim cov kabmob steel yog nruam casting thiab hluav taws xob rauv smelting ntxiv rau electroslag remelting. Ib tug me me ntawm ob lub tshuab nqus tsev los yog ntau lub tshuab nqus tsev noj tus kheej yog siv los txhim kho qhov zoo ntawm cov kabmob steel.
Lub smelting zoo ntawm bearing steel yuav tsum tau siab heev, thiab cov ntsiab lus ntawm leej faj, phosphorus, hydrogen, thiab lwm yam, raws li zoo raws li kom muaj nuj nqis, loj thiab faib ntawm non-metallic inclusions thiab carbides yuav tsum tau nruj me ntsis tswj. Vim tias qhov ntau, qhov loj thiab kev faib tawm ntawm cov khoom tsis yog xim hlau thiab cov carbides muaj kev cuam tshuam zoo rau lub neej kev pabcuam ntawm cov kabmob steel, qhov tsis ua haujlwm ntawm cov kabmob feem ntau yog tshwm sim los ntawm kev nthuav tawm ntawm microcracks nyob ib ncig ntawm cov khoom loj lossis carbides.
