liab fused alumina, raws li cov khoom siv zoo hnav-tiv taus, muaj ntau yam kev siv hauv kev lag luam. Niaj hnub no, peb yuav tham txog cov yam ntxwv, daim ntawv thov teb thiab kev txhim kho yav tom ntej ntawm chromium-corundum, thiab coj koj mus rau qhov paub tsis meej ntawm cov khoom siv yees siv no.
Dab tsi yog qhovliab fused alumina?
liab fused alumina, tseem hu ua chromium aluminium corundum lossis chromium corundum abrasive, yog cov khoom siv hluavtaws ua los ntawm alumina thiab chromite smelting ntawm qhov kub thiab txias. Nws muaj cov yam ntxwv ntawm siab hardness, siab hnav tsis kam, siab zog thiab zoo tshuaj stability, yog li nws tau dav siv nyob rau hauv ntau lub teb.
Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov ntawm paj yeeb fused alumina?
Cov ntawv thov tseem ceeb ntawm chrome corundum suav nrog abrasives, refractories, ceramic kev lag luam thiab kev lag luam casting. Nyob rau hauv abrasive abrades, chrome corundum yog dav siv nyob rau hauv hlau ua, zeb ua thiab lwm yam lag luam vim nws siab hardness thiab hnav tsis kam. Nyob rau hauv lub tshav pob ntawm cov ntaub ntawv refractory, qhov kub thiab txias stability thiab tshuaj stability ntawm chrome corundum ua rau nws yog ib qho zoo tagnrho xaiv rau kev tsim cov refractory bricks, castables thiab lwm yam khoom. Tsis tas li ntawd, hauv kev lag luam ceramic, chromium corundum yog siv los ua cov khoom siv ceramic los txhim kho cov hnav tsis kam thiab hardness ntawm cov khoom siv ceramic. Hauv kev lag luam casting, chrome corundum tuaj yeem siv los ua cov xuab zeb casting los txhim kho qhov zoo ntawm qhov chaw thiab qhov tseeb ntawm cov castings.
Dab tsi yog qhov zoo of liab fused aluminapiv nrog rau lwm yam hnav-resistant khoom?
Chromium-corundum muaj zog dua thiab hnav tsis kam dua li lwm cov ntaub ntawv hnav-tiv taus, feem ntau yog vim nws cov qauv siv lead ua tshwj xeeb thiab tshuaj lom neeg muaj pes tsawg leeg. Nyob rau tib lub sijhawm, chromium corundum kuj muaj cov tshuaj tiv thaiv corrosion zoo thiab tuaj yeem tswj kev ua haujlwm ruaj khov hauv qhov chaw hnyav xws li kua qaub thiab alkali. Tsis tas li ntawd, chromium corundum kuj muaj thermal stability thiab mechanical zog, yog li nws muaj peev xwm tswj tau qhov kev ua tau zoo nyob rau hauv huab cua txias xws li kub thiab siab.
Nrog nws zoo heev hnav tsis kam, siab hardness thiab zoo tshuaj stability, liab fused alumina tau qhia muaj zog daim ntawv thov muaj peev xwm nyob rau hauv ntau yam teb. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm kev lag luam, peb muaj laj thawj ntseeg tias chrome corundum yuav ua lub luag haujlwm tseem ceeb dua yav tom ntej thiab ua kom muaj txiaj ntsig ntau dua rau kev nce qib thiab kev loj hlob ntawm kev lag luam.
