High chrome cib yog tsim los ntawm magnesia (MgO) thiab chromium oxide (Cr2O3) ua cov khoom tseem ceeb, periclase thiab spinel raws li cov pob zeb tseem ceeb ntawm cov khoom siv refractory. Xws li cib siab refractoriness, kub siab zog, tsis kam mus rau yooj yim slag yaig kuj, zoo thermal stability, acidic slag kuj muaj ib co adaptability. Lub ntsiab raw khoom los tsim cov chrome refractory cib yog sintered magnesia thiab chromite. Purity magnesia raw khoom kom siab li ntau tau, cov kev cai ntawm cov tshuaj muaj pes tsawg leeg ntawm chromite yog: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.
High chrome cib feem ntau muaj xws li Cr2O3, monoclinic zirconia thiab alumina hmoov. Yog li ntawd, kev ua tau zoo ntawm high chromebricks yog ze ze rau kev ua haujlwm ntawm cov tshuaj no. High chrome hluav taws cib muaj chromium hemitrioxide 30%, thiab siab chrome cib yog tshwj xeeb nrog cov kua qaub thiab alkali slags tsis kam, thiab feem ntau yog siv nyob rau hauv cov txheej txheem cais, thiab nonferrous smelting furnaces, thiab lwm yam.
High chrome refractory cib yog tsim los ntawm cov khoom zoo magnesite thiab chrome ore nplua nqi sib tov. Raws li kev xav tau sib txawv, kho cov ntsiab lus ntawm Cr2O3, cov khoom siv thermal stability thiab kev ua haujlwm kub siab yog qhov txaus siab. High chrome bricks yog dav siv nyob rau hauv cov cement kiln thiab nonferrous metallurgical rauv thiab lwm yam.

High chrome bricks yuav siv tau nyob rau hauv metallurgical kev lag luam, architectural khoom kev lag luam, thiab lwm yam uas tsis yog-ferrous smelting rauv, thiab lwm yam thiab kuj yuav siv tau rau kab lub sintering cheeb tsam ntawm qhuav tshiab ua cement kilns thiab iav tank furnaces li checkers thiab cov lwm lub tshuab cua sov.
RS refractory Hoobkas yog tus kws tshaj lij chrome refractory cib xa khoom uas tau tsim nyob rau hauv thaum ntxov 90s ntawm nees nkaum caug xyoo. RS refractory Hoobkas tau tshwj xeeb hauv siab chrome thaiv rau ntau tshaj 20 xyoo. Qhov zoo ntawm RS Refractory Factory yog raws li hauv qab no:
