Brown fused alumina, tseem hu ua xim av aluminium oxide lossis emery, yog cov khoom siv hluavtaws uas ua los ntawm fusing bauxite, cov ntaub ntawv carbon, thiab hlau filings nyob rau hauv hluav taws xob arc rauv. Cov khoom siv tau muaj cov yam ntxwv xim av thiab cov khoom sib tsoo zoo heev.
Nws cov tshuaj tiv thaiv tseem ceeb yog aluminium oxide (Al₂O₃), feem ntau suav txog 95.00% - 97.00% ntawm nws cov muaj pes tsawg leeg, nrog me me ntawm hlau, silicon, titanium, thiab lwm yam. Raws li ib qho ntawm feem ntau siv cov pa abrasives, xim av aluminium oxide muaj nuj nqis rau nws cov kev sib tsoo zoo, ntau yam kev siv, thiab tus nqi -kev ua tau zoo.
Cov yam ntxwv ntawm Brown Fused Alumina
Ua los ntawm qib siab - zoo abrasive- qib bauxite thiab xaiv cov khoom siv pabcuam, xim av corundum yog ua kom zoo rau hauv lub qhov cub hluav taws xob ntawm qhov kub siab tshaj 2,250℃. Tom qab kev kho dua tshiab, siab - sib nqus sib nqus tshem tawm cov impurities. Nws refractoriness tshaj 1,850 degree.
Peb cov xim av aluminium oxide nta siab purity, zoo -tsim crystals, zoo flowability, tsis tshua muaj coefficient ntawm linear thermal expansion, thiab zoo heev corrosion kuj.
Thaum lub sij hawm siv, nws tswj cov txheej txheem zoo stability thiab tiv thaiv bursting, ntau tawg, thiab tawg. Cov khoom no ua rau nws haum rau ntau yam kev siv hauv kev lag luam abrasive thiab refractory.

Brown aluminium oxide yog dav siv los tsim kev sib tsoo log, abrasive siv, sandpaper, abrasive daim ntaub, txiav discs, coated abrasives, thiab bonded abrasives. Nws kuj yog siv rau hauv sandblasting, nto sib tsoo, hnav- tiv taus flooring, thiab waterjet txiav.
2. Cov khoom siv refractory
Hauv kev lag luam refractory, xim av corundum yog siv nyob rau hauv castables, refractory cib, ramming mixes, zawv zawg rooj vag daim hlau, nozzles, ladle linings, thiab rauv hauv ob sab phlu. Nws kuj tseem tsim nyog rau kev nqis peev casting thiab lwm yam siab -kub siv kev lag luam.
Hom Brown Fused Alumina
1. Brown Fused Alumina Lumps
Brown corundum lumps muaj siab -kub tsis kam, corrosion kuj, thiab siab mechanical zog. Lawv yog siv nyob rau hauv refractory daim ntaub ntawv xws li zawv zawg rooj vag nozzles rau steel casting, raws li zoo raws li linings rau blast furnaces thiab khoom siv nyob rau hauv lub smelting ntawm tsawg hlau thiab tshwj xeeb alloys. Lwm daim ntawv thov suav nrog cov khoom siv hluav taws xob, cov hluav taws xob, hluav taws xob- cov txheej txheem tiv thaiv, thiab oxidation- cov khoom tiv thaiv.
Ua tsaug rau lawv cov tawv tawv thiab hnav tsis kam, cov pob no kuj tseem siv los tsim cov khoom siv reactor, cov kav dej, tshuaj twj tso kua mis, cov khoom siv tshuab, hlau - kos duab tuag, xaum - txhuas extrusion tuag, cov cuab yeej txiav, thiab pwm- ua abrasives. Cov ntawv thov ntxiv muaj xws li cov khoom siv tiv thaiv ballistic, cov khoom sib koom ua ke, thiab cov nplhaib sib khi.
2. Brown Fused Alumina rau Roller Sanding Applications
Rau cov ntaub ntawv sanding, ob qho tib si grain thiab particle loj yog qhov tseem ceeb hauv kev xaiv cov khoom. Qhov zoo ntawm cov xim av aluminium oxide feem ntau nyob ntawm cov yam ntxwv ntawm nws cov ntaub ntawv raw khoom thiab cov txheej txheem tom ntej.
Nyob ntawm daim ntawv thov, cov nplej uas tsim nyog yuav muaj qhov sib txawv me me, sib npaug los yog ze rau -cov duab kheej kheej, kev cuam tshuam zoo, thiab qhov chaw huv. Cov yam ntxwv no pab ua kom muaj kev ua haujlwm zoo sib xws.
3. Brown Fused Alumina Peev Casting Sand
Kev nqis peev casting xuab zeb yog tsim los ntawm xim av corundum siv cov txheej txheem tshwj xeeb tsim los ntawm cov neeg ua haujlwm paub txog. Cov txheej txheem tsim khoom tswj tau pab xa cov yam ntxwv ntawm cov nplej uas xav tau rau kev ua kom zoo.
Cov khoom siv no tsim nyog rau cov ntawv thov uas qhov kev ua tau zoo refractory, qhov ruaj khov, thiab tsis kam mus rau qhov kub thiab txias yog qhov tseem ceeb.
4. Brown Fused Alumina Barmac Xuab zeb
Brown aluminium oxide Barmac xuab zeb yog ua tiav siv Barmac- hom kab ntau lawm kom ua tiav cov yam ntxwv uas yuav tsum tau ua.
Thaum siv cov cuab yeej sib tsoo, nws muaj kev txiav txim siab, tsis tshua muaj cua sov, qhov sib tsoo siab, thiab txo qhov adhesion thaum siv.
Sintered abrasive cov cuab yeej ua nrog cov khoom siv no tuaj yeem tsim cov xim xiav sib sib zog nqus tom qab tua hluav taws thiab ua kom pom kev zoo nkauj, nrog mesh tsawg dua -xws li tawg thiab xeb stains. Ntxuav cov khoom kuj yuav pab txo cov plua plav seem.
5. Brown Fused Alumina P-Qib Abrasive
Brown corundum P-qib abrasive yog calcined ntawm qhov kub ntawm 1,000℃mus rau 1,300℃. Cov txiaj ntsig angular nplej muaj peev xwm txiav tau zoo thiab tus kheej zoo -sharpening kev ua tau zoo. Kev kho cua sov ntxiv txhim kho lawv cov tawv nqaij, ua rau lawv haum rau siab -kev ua tau zoo coated abrasives.
Cov ntawv thov muaj xws li cov ntawv xuab zeb zoo thiab cov siv tawv abrasive, qhov kev ua haujlwm zoo sib xws thiab kev ua haujlwm ntev yog qhov tseem ceeb.
6. Brown Fused Alumina Segment Abrasive
Brown aluminium oxide ntu abrasive yog tsim los ntawm siab - zoo bauxite, anthracite, thiab hlau filings siv niaj hnub, tshwj xeeb ntau lawm cov tswv yim.
Nws muaj nuj nqis rau nws lub sijhawm sib tsoo luv luv, kev ua haujlwm siab, kev ua haujlwm ruaj khov, thiab tus nqi sib tw. Cov yam ntxwv no ua rau nws muaj kev xaiv zoo rau kev sib tsoo thiab lwm yam kev siv abrasive qhov twg cov khoom tsim tau thiab kev tswj hwm tus nqi yog qhov tseem ceeb rau kev txiav txim siab.
