Chromium corundum, vim nws qhov kev ua tau zoo heev, yog dav siv nyob rau hauv high-temperature teb nrog hnyav ib puag ncig, nrog rau cov uas tsis yog-ferrous metallurgical kilns, iav melting kilns, carbon dub tshuaj tiv thaiv furnaces, khib nyiab incinerators, thiab lwm yam. Thaum pib ntawm nws txoj kev loj hlob, chromium corundum yog dav siv nyob rau hauv cov hlau cement. Txawm li cas los xij, vim muaj kev txhawb zog ntawm tib neeg kev paub txog ib puag ncig, kev hu rau kev lag luam chromium dawb-kub tau nce siab. Ntau lub teb tau tsim lwm cov khoom lag luam, tab sis chromium corundum tseem muaj nyob hauv qee qhov chaw uas muaj kev pabcuam hnyav.
Chromium muaj cov khoom siv refractory, vim lawv cov khoom tshwj xeeb, tau siv tau zoo hauv cov khoom siv hlau tsis muaj hlau tsis zoo. Txawm hais tias tam sim no muaj ntau tus kws tshawb fawb tab tom kawm txog kev hloov pauv ntawm chromium dawb ntawm cov ntaub ntawv refractory siv nyob rau hauv thaj chaw ntawm cov hlau tsis muaj hlau, kev siv cov chromium uas muaj cov ntaub ntawv refractory li smelting furnace lining nyob rau hauv lub tshav pob ntawm non-ferrous metallurgy tseem yog lub ntsiab rau tam sim no. Piv txwv li, cov ntaub ntawv refractory siv nyob rau hauv Ausmet tooj liab smelting rauv tsis tsuas yog yuav tsum tau tiv thaiv yaig ntawm cov yaj (SiO2 / FeO slag, tooj liab kua, tooj liab matte) thiab roj theem yaig, tab sis kuj yuav kov yeej kub hloov pauv los ntawm kev hloov ntawm cov tshuaj tsuag. Kev pabcuam ib puag ncig hnyav, thiab tam sim no tsis muaj cov khoom siv nrog kev ua tau zoo dua los hloov tshwj tsis yog chromium uas muaj cov khoom siv refractory. Tsis tas li ntawd, zinc volatilization kiln, tooj liab converter, Coal gasification rauv thiab carbon dub reactor kuj ntsib tib yam teeb meem.
