Pob zeb chrome corundum yog hais txog cov khoom siv corundum refractory uas muaj Cr2O3. Thaum kub siab, Cr2O3 thiab Al2O3 tsim cov khoom khov kho tas mus li, yog li qhov ua tau zoo ntawm cov khoom chrome corundum kub siab dua li cov khoom corundum ntshiab. Pob zeb hluav taws chrome corundum siv rau hauv petrochemical gasifier yuav tsum muaj silicon qis, hlau qis, alkali qis thiab purity siab, thiab yuav tsum muaj qhov ceev thiab lub zog siab. Cov ntsiab lus ntawm Cr2O3 yog nyob rau hauv qhov ntau ntawm 9% ~ 15%
Chrome Corundum Cib Nta
- Kev tiv thaiv hluav taws kub siab,
- Lub zog loj,
- Kev hnav tsis kam zoo,
- Kev tiv thaiv thermal zoo,
- Zoo tiv taus kua qaub thiab alkali,
- Kev ruaj khov tshuaj zoo.
Cov Txheej Txheem Tsim Khoom Siv Chrome Corundum
Cov cib chrome corundum yog ua tiav nrog post-al2o3, ntxiv ib qho nyiaj ntawm chromium oxide hmoov thiab hmoov zoo ntawm chrome corundum clinker, uas tau tsim thiab hlawv ntawm qhov kub siab. Cov ntsiab lus ntawm chromic oxide hauv cov cib sintered chrome feem ntau qis dua li ntawm fused cast chrome corundum cib. Chrome corundum block kuj siv cov av nkos casting txoj kev npaj, alpha Al2O3 hmoov thiab chrome oxide hmoov sib tov, ntxiv cov kua nplaum thiab cov organic adhesives ua los ntawm cov av nkos tuab, tib lub sijhawm ib feem ntawm chromium corundum clinker, los ntawm grouting rau hauv adobe, hlawv dua.

Siv Chrome Corundum Cib rau Qhov Cub
Cov cib chrome corundum feem ntau yog siv rau hauv cov cheeb tsam uas xav tau kev kub hnyiab thiab kub tsis kam, xws li cov cib gliding rail hauv cov hlau pusher metallurgical furnaces, lub tapping platform style walking beam furnaces, thiab tseem yog sab hauv rau cov destructors, Hauv cov linings ntawm carbon soot furnaces thiab tooj liab smeling furnaces tapping platform ntawm dov zeb furnaces, rov ua kom sov lub cub tawg skid rail.
