Cov cib chrome siab yog ua los ntawm magnesia (MgO) thiab chromium oxide (Cr2O3) ua cov khoom tseem ceeb, periclase thiab spinel ua cov khoom tseem ceeb ntawm cov khoom siv refractory. Cov cib no muaj kev kub siab, lub zog kub siab, tiv taus kev yaig ntawm cov slag yooj yim, ruaj khov zoo heev, thiab muaj qee qhov kev hloov pauv tau. Cov khoom siv tseem ceeb los tsim cov cib refractory siab chrome yog sintered magnesia thiab chromite. Cov khoom siv magnesia yuav tsum muaj purity siab li sai tau, cov tshuaj lom neeg ntawm chromite yuav tsum yog: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.
Cov cib chrome siab feem ntau yog ua los ntawm Cr2O3, monoclinic zirconia thiab alumina hmoov. Yog li ntawd, kev ua tau zoo ntawm cov cib chrome siab muaj feem cuam tshuam nrog kev ua tau zoo ntawm cov tshuaj no. Cov cib hluav taws kub chrome siab muaj chromium hemitrioxide 30%, thiab cov cib chrome siab muaj cov kua qaub thiab alkali tsis kam, thiab feem ntau yog siv rau hauv txheej cais, thiab cov cub tawg uas tsis yog ferrous, thiab lwm yam.
Cov cib refractory chrome siab yog ua los ntawm cov magnesite zoo thiab chrome ore fine charge sib xyaw. Raws li qhov xav tau sib txawv, kho cov ntsiab lus ntawm Cr2O3, qhov ruaj khov thermal ntawm cov khoom thiab kev ua haujlwm kub siab yog qhov txaus siab. Cov cib chrome siab yog siv dav hauv cov cement kiln thiab cov cub tawg metallurgical uas tsis yog ferrous thiab lwm yam.

Cov cib chrome siab tuaj yeem siv rau hauv kev lag luam hlau, kev lag luam khoom siv vaj tse, thiab lwm yam khoom siv hluav taws xob uas tsis yog ferrous, thiab kuj tuaj yeem siv rau kab ntawm thaj chaw sintering ntawm cov txheej txheem qhuav tshiab ntawm cov cement kilns thiab cov iav tank furnaces ua checkers thiab lwm yam khoom siv hluav taws xob.
RS Refractory Factory yog ib lub tuam txhab tsim khoom siv cib ua los ntawm cov chrome siab uas tau tsim tsa thaum ntxov xyoo 1990s ntawm lub xyoo pua nees nkaum. RS Refractory Factory tau tshwj xeeb hauv kev tsim cov cib ua los ntawm cov chrome siab rau ntau tshaj 20 xyoo. Cov txiaj ntsig ntawm RS Refractory Factory yog raws li nram no:
