Properties thiab Classification ntawm Corundum
Brown corundumBrown corundum yog tsim los ntawm bauxite, anthracite thiab hlau filings los ntawm smelting ntawm kub kub nyob rau hauv hluav taws xob arc rauv. Hauv cov txheej txheem smelting, cov pa roj carbon monoxide hauv anthracite bauxite hauv silicon oxide, hlau oxide thiab titanium oxide impurities txo rau hlau, rau qee cov hlau ...
Brown corundum xim av corundumyog tsim los ntawm bauxite, anthracite thiab hlau filings los ntawm smelting ntawm kub kub nyob rau hauv hluav taws xob arc rauv. Nyob rau hauv cov txheej txheem smelting, cov pa roj carbon nyob rau hauv anthracite bauxite nyob rau hauv silicon oxide, hlau oxide thiab titanium oxide impurities txo rau hlau, rau ib co hlau ua ke ua ferroalloy, vim nws feem ntau yog corundum molten kua thiab nyob rau hauv qab ntawm lub cub tawg thiab corundum molten kua sib cais. Tsuas yog ib qho me me ntawm impurities suav nrog hauv corundum yaj.Lub ntsiab ntxhia ntawm cov xim av corundum yog lub cev corundum, trigonal siv lead ua kab ke, ib qho me me ntawm cov pob zeb hauv av impurities yog: calcium silicate, calcium plagioclase, aluminium-nplua nuj andalusite (tseem hu ua mullite. ) titanium, vitreous lub cev thiab ib qho me me ntawm cov hlau alloy.Brown corundum muaj zog crushing tsis kam, oxidation kuj thiab corrosion kuj, thiab muaj tshuaj zoo stability. Nws yog ib qho siv dav siv abrasive. Nws yog tsim rau kev sib tsoo cov ntaub ntawv hlau nrog lub zog tensile siab, xws li cov pa roj carbon zoo tib yam, tawv bronze, alloy steel zoo sib tsoo thiab zoo sib tsoo, sib tsoo xov thiab lub zog, thiab lwm yam. Dawb corundum kuj siv tau rau precision casting thiab qib high-refractory. cov ntaub ntawv.
Chrome corundum (PA) Cov txheej txheem smelting ntawm chrome corundum yog tib yam li cov dawb corundum, tshwj tsis yog tias muaj qee yam ntawm chromium oxide ntxiv rau hauv cov txheej txheem smelting, uas yog lub teeb liab lossis xim liab.Chromium corundum vim yog kev taw qhia ntawm Cr3+ txhawm rau txhim kho cov tawv tawv ntawm cov tawv nqaij tawv yog siab dua li ntawm cov dawb corundum, thiab cov tawv tawv zoo ib yam li cov dawb corundum. Thaum nws yog siv rau kev uacov ntaub ntawvnrog ntau dua toughness, nws cov kev ua tau zoo yog siab dua li ntawm dawb corundum, thiab nto tiav ntawm lub workpiece kuj zoo dua. Chromium corundum yog qhov tsim nyog rau kev ua cov khoom ua haujlwm nrog lub siab tawv, xws li cov hlau tawv tawv, hlau alloy, cov cuab yeej ntsuas ntsuas thiab ntsuas qhov ntsuas. Microcrystalline corundum (MA)
Cov ntaub ntawv raw thiab smelting txoj kev ntawm microcrystalline corundum yeej ib txwm zoo ib yam li cov xim av corundum, thiab cov molten kua yog poured rau hauv ceg pwm sai txias (feem ntau nyob rau hauv 30 feeb) tam sim ntawd tom qab lub cub tawg lawm. Qhov kev txo qis ntawm impurities tsis zoo, cov ntsiab lus ntawm A1203 yog 94 ~ 96%, cov siv lead ua loj yog feem ntau 80 ~ 300 microns, cov siv lead ua nyiaj rau 57 ~ 85%, thiab qhov siab tshaj plaws siv lead ua tsis tshaj 400 ~ 600 microns. Nws muaj cov yam ntxwv ntawm siab zog thiab ntau dua toughness. Haum rau kev sib tsoo hnyav, tuaj yeem sib tsoo stainless hlau, carbon steel, bearing steel thiab tshwj xeeb ductile hlau thiab lwm yam ntaub ntawv, vim hais tias cov abrasive hais nyob rau hauv cov txheej txheem sib tsoo yog micro-ntug tawg lub xeev, kuj yog siv rau precision sib tsoo thiab txawm daim iav sib tsoo.
