Cov kev ceev faj:
Thaum lub sij hawm kev thauj mus los, thauj khoom, tshem tawm thiab siv, kev puas tsuaj rau saum npoo ntawm cov yeeb nkab steel yuav tsum raug zam kom tsis txhob cuam tshuam rau kev siv.
Ua ntej siv, kev tshuaj xyuas yuav tsum tau ua kom paub tseeb tias tsis muaj cov kab nrib pleb, dents, nti thiab lwm yam tsis xws luag ntawm cov yeeb nkab steel.
Thaum siv, kev saib xyuas yuav tsum tau them nyiaj rau kev tswj xyuas qhov huv ntawm cov yeeb nkab steel kom tsis txhob muaj roj, plua plav thiab lwm yam impurities nkag mus rau sab hauv ntawm cov yeeb nkab steel thiab cuam tshuam rau kev siv.
