Chromic corundum

Chrome corundum:
Lub ntsiab ntxhia muaj pes tsawg leeg yog α-Al2O3-Cr2O3 cov kuab tshuaj.
Cov ntxhia hauv nruab nrab yog ib qho me me ntawm cov sib xyaw spinel (lossis tsis muaj spinel), thiab cov ntsiab lus ntawm chromium oxide yog 1% ~ 30%.
Muaj ob hom fused chrome corundum cib thiab sintered chrome corundum cib.
Feem ntau, chrome corundum cib hais txog sintered chrome corundum cib.Siv α-Al2O3 raws li cov khoom siv raw, ntxiv qhov tsim nyog ntawm chromic oxide hmoov thiab chromic corundum clinker hmoov, sib sau, hlawv ntawm qhov kub thiab txias.Cov ntsiab lus chromium oxide ntawm sintered chrome rigid cib feem ntau qis dua li ntawm fused cam khwb cia chrome corundum cib.Nws tseem tuaj yeem npaj los ntawm cov av nkos casting.Cov α-Al2O3 hmoov thiab chromium oxide hmoov yog sib tov sib xyaw, thiab tus neeg sawv cev degumming thiab organic binder tau ntxiv los ua cov av nkos tuab.Nyob rau tib lub sijhawm, qee qhov chromium corundum clinker ntxiv, thiab lub cib billet yog tsim los ntawm txoj kev grouting thiab tom qab ntawd raug rho tawm haujlwm.Nws tuaj yeem siv los ua lub hauv ob sab ntawm iav kiln, npog cib ntawm kos iav ntws qhov thiab thim rov qab ntawm cov hlau kub pretreatment ntaus ntawv, khib nyiab incinerator, thee dej slurry siab gasifier, thiab lwm yam.
