Kev xaiv ntawm cov ntaub ntawv refractory rau cov ua hauj lwm hauv ob sab phlu nws txawv nyob ntawm seb hom steel siv nyob rau hauv ladle smelting. Thaum smelting low-carbon steel thiab txhuas tua hlau, aluminium spinel cib, aluminium spinel castables, los yog tsawg-carbon magnesia carbon cib yuav tsum tau siv los ua cov txheej txheem ua haujlwm. Thaum smelting steel qib nrog siab manganese thiab oxygen cov ntsiab lus, magnesia carbon cib thiab aluminium magnesia carbon cib yuav tsum tau siv los ua cov txheej txheem ua haujlwm. Cov khoom siv tshuaj tsuag los ntawm magnesium yuav tsum tau siv. Rau smelting tshwj xeeb steel qib nrog qis P thiab qis S, dolomite cib yuav tsum tau siv los ua cov txheej txheem ua haujlwm.
Cov ntaub ntawv refractory siv nyob rau hauv ladle slag kab cheeb tsam, ladle hauv qab, ladle phab ntsa thiab lwm cov txheej txheem ua hauj lwm yuav tsum muaj kev ua tau zoo ntawm kev kub siab, slag corrosion kuj, thermal shock resistance, thiab spalling kuj. Lub ladle ua haujlwm tsis tu ncua, thiab qhov kub thiab txias hloov ntau zaus los ntawm siab mus rau qis, los ntawm qis mus rau siab. Yog li ntawd, cov ntaub ntawv refractory siv rau hauv ob sab phlu yuav tsum muaj kev ua tau zoo ntawm kev ua kom txias sai thiab kub ua haujlwm.
