Brown corundum yog cov khoom siv kub kub refractory uas ua los ntawm cov khoom siv hluav taws xob los ntawm cov khoom siv bauxite li raw khoom, uas yog refined thiab refined los ntawm high-temperature smelting nyob rau hauv ib tug hluav taws xob arc rauv. Vim nws cov hardness siab, purity, thiab muaj zog sib tsoo muaj peev xwm, nws tau dhau los ua ib qho ntawm cov kev sib tsoo yooj yim tshaj plaws thiab polishing consumables. Lub caij no, ntxiv rau kev siv los ua ib qho abrasive, xim av corundum kuj muaj kev tiv thaiv corrosion thiab kub kub, thiab yog siv dav hauv kev tsim khoom thiab ua cov khoom siv ruaj khov.
Txawm li cas los xij, nyob rau hauv xyoo tas los no, nrog kev nce ntawm cov tuam txhab tsim cov xim av corundum, qhov zoo ntawm bauxite tau poob qis, thiab cov nqi hluav taws xob tau nce ntxiv, cov nqi tsim cov xim av corundum tau ntsib kev nyuaj siab. Tsis tas li ntawd, kev sib tw ua lag luam yog qhov hnyav, cov txiaj ntsig tau maj mam txo qis, thiab cov khoom lag luam zoo kuj maj mam poob. Qhov zoo yog tsis ruaj tsis khov, thiab phenomena xws li hmoov thiab cracking feem ntau tshwm sim, uas tau dhau los ua ib qho teeb meem ntawm cov xim av corundum thiab qhov tseeb tias cov khoom siv refractory manufacturers nrhiav nyuaj rau txais.
Cov yam ntxwv ntawm cov xim av corundum yog tias nws muaj ntau impurities, yog xim av xim, muaj zog hardness thiab zoo toughness, muaj peev xwm tiv taus loj sib tsoo quab yuam, thiab yog haum rau sib tsoo cov ntaub ntawv xws li carbon steel, alloy steel, stainless hlau, nyuaj. bronze, thiab lwm yam. Nws kuj yog pheej yig thiab dav siv. Cov ntsiab lus tseem ceeb ntawm xim av corundum yog 15% -25%, thiab qhov txawv ntawm ob yog dab tsi? 15% xim av corundum sib tsoo pob zeb muaj xim tsaus nti thiab xim av corundum cov ntsiab lus tsawg dua. Yog li ntawd, thaum lub sij hawm rov sib tsoo txheej txheem, txawm hais tias lub txiav quab yuam yog txaus, nws yog heev hnav-resistant. Cov khoom hauv av muaj ntau cov dej stains, uas cuam tshuam rau qhov chaw tsim khoom thiab ua rau nws nyuaj rau kev xeem ib puag ncig; Cov xim av corundum sib tsoo pob zeb nrog 25% cov ntsiab lus muaj cov xim sib dua, cov ntsiab lus ntau dua ntawm cov xim av corundum xuab zeb, muaj zog sib tsoo, thiab dej tsawg dua thiab cov av nkos tom qab sib tsoo, uas tuaj yeem saib xyuas los ntawm kev tiv thaiv ib puag ncig.
Brown corundum sib tsoo pob zeb tau muab faib ua oblique cylindrical, oblique daim duab peb sab, daim duab peb sab, thiab cov duab kheej kheej, nrog cov khoom sib txawv thiab qhov ntau thiab tsawg. Kev xaiv ntawm cov duab thiab cov lus qhia tshwj xeeb yog nyob ntawm tus neeg siv khoom tus kheej cov khoom siv thiab cov kev xav tau kom tau raws li
