High hardness refractory Brown Fused Alumina
Product Description
Brown fused alumina bauxite li raw khoom, thee, hlau, kub siab tshaj 2000 degrees hitches nyob rau hauv arc smelting, lub zeb sib tsoo yas, sib nqus sib cais rau hlau, tshuaj ntsuam yog muab faib ua ntau yam particle loj, ntom ntom ntom, siab hardness, particle tsim globular, siab consolidation yog tsim rau ua ceramic, resin abrasive thiab sib tsoo, polishing, sandblasting, casting, thiab lwm yam., kuj yuav siv tau rau manufacturing advanced refractories.
Brown corundum nws lub luag haujlwm tseem ceeb:
1.Vim nws lub zog siab thiab lwm yam khoom, nws yog siv los cam khwb cia hlau zawv zawg nozzle, smelting tsis tshua muaj hlau, tshwj xeeb alloys, ceramics, blast furnace hauv ob sab phlu (phab ntsa thiab yeeb nkab);Lub cev thiab cov khoom siv tshuaj, lub txim hluav taws xob, cua sov - oxidation - resistant txheej.
2.Vim yog cov yam ntxwv ntawm hardness, zoo poj niam txiv neej, siab zog, nyob rau hauv cov tshuaj, siv raws li ib tug ntau yam ntawm cov tshuaj tiv thaiv hlab ntsha thiab cov kav dej, tshuaj twj tso kua mis qhov chaw;Ua txhua yam khoom, txhua yam pwm, xws li hlau kos pwm, nyem cwj mem core pwm lub qhov ncauj, thiab lwm yam.;Ua cov cuab yeej, pwm abrasives, cov ntaub ntawv mos txwv, tib neeg cov pob qij txha, sealing nplhaib thiab lwm yam.
3.Corundum rwb thaiv tsev cov ntaub ntawv, xws li corundum lub teeb ci ci, corundum hollow pob thiab fiber ntau cov khoom, siv nyob rau hauv ntau yam kub kub rauv phab ntsa thiab sab saum toj, ob qho tib si kev txuag hluav taws xob.Emery particle loj xuab zeb yog tsim los ntawm dag emery thaiv, siv cov menyuam, pob sib tsoo, barmark thiab lwm yam khoom siv, particle loj los ntawm F8-F325.Feem ntau yog siv rau polishing, sib tsoo, muaj kev sib tsoo, thiab lwm yam, kuj tuaj yeem ntxuav raws li cov neeg siv khoom xav tau, pickling thiab lwm yam kev ua, kom tau raws li qhov sib txawv ntawm cov neeg siv khoom.
Tsawg carbon xim av corundum tom qab lub cub tawg thiab cov txheej txheem tshwj xeeb ntawm reprocessing, txo cov ntsiab lus ntawm residual carbon nyob rau hauv xim av corundum, kom cov khoom siv tsis pulverized, tsis tawg, toughness yog abrasives kev lag luam, refractory kev lag luam raw cov ntaub ntawv.Feem ntau yog siv rau ceramic abrades, abrades, organic abrades, siv tawv, coated abrades, thiab lwm yam., raws li cov residual carbon cov ntsiab lus muab faib ua: calcined xim av corundum C ≤0.05%, tsawg carbon xim av corundum C ≤0.10%, zoo tib yam xim av corundum C. ≤0.15%.
