Corundum Mullite Castable piav qhia
Corundum mullite refractory castable yog ib yam ntawm lub zog siab tsis zoo li cov ntaub ntawv refractory muag hauv RS tuam txhab, uas tuaj yeem siv rau hauv cov cement kiln. Corundum mullite castables tuaj yeem ua tau cov khoom zoo xws li siab crushing lub zog, kub stability, thermal shock resistance, hnav thiab tshuaj yaig kuj nyob rau hauv ob sab phlu ntawm lub hwj chim chaw nres tsheb loj boiler thiab lwm yam high kub equipments. refractory corundum mullite castable yuav siv tau nyob rau hauv steel rauv, cement kiln, iav rauv, hlau ua rauv, ceramic tunnel kiln thiab hais txog.
Cov khoom ntawm Corundum Mullite Castable
- Siab zog,
- Muaj zog hnav tsis kam,
- Zoo erosion kuj,
- Zoo heev thermal shock stability,
- Kub kub kuj.
Kev tsim cov txheej txheem ntawm Corundum Mullite Castable
Cov ntaub ntawv tseem ceeb ntawm corundum mullite castable yog lub teeb yuag aluminium oxide aggregate, zoo siab ntshiab ntuj mullite ore, thiab calcium aluminate cement ua tus neeg sawv cev sib txuas. corundum mullite refractory castable yog tsim los ntawm kev kub kub kub los ntawm cov khoom siv hluav taws xob siab heev. corundum mullite flexural lub zog thiab compressive zog nce ua ntej thiab txo qis tom qab ntawd nrog qhov nce ntawm kev kho cua sov. Thiab thaum alumina micro zog cov ntsiab lus yog 5%, lub zog flexural mus txog rau sab saum toj.
Kev sib xyaw ntawm Corundum Mullite Castable
Cov ntsiab lus ntawm Al2O3 yog ntau tshaj 90%, thiab corundum mullite rwb thaiv tsev castable nrog corundum raws li lub ntsiab siv lead ua theem yog tov nrog tsim nyog dispersants, coagulants, stainless hlau fibers, uas yog compounded raws li nruj qauv. Refractory corundum mullite castable muaj ntau yam ntxwv, xws li kub siab zog, hnav-tiv taus thiab anti-scour, siab kub conduction, tshav kub tsis kam, corrosion kuj, zoo sealing thiab thaum ntxov condensation.

- Daim ntawv thov ntawm Corundum Mullite Castable
- Corundum mullite refractory castable muaj cov yam ntxwv ntawm kev nthuav dav, zoo heev thermal shock tsis kam, siab kub ntim stability, siab kub lub zog, siab refractoriness nyob rau hauv load, tsis tshua muaj kub creep tus nqi, siab crushing zog, tsis tshua muaj linear dimensional hloov tus nqi, siab hardness, zoo tsis kam mus rau tshuaj corrosion, spalling thiab hnav tsis kam. Vim yog cov cim zoo li no, thiab corundum mullite rwb thaiv tsev castable yog siv tau ntev thiab uas tau siv dav hauv cov khoom siv sib txawv, qhov cub kub kub thiab lwm qhov tseem ceeb ntawm qhov kub thiab txias, xws li:
- Boiler, moj tej tawg rauv, kub moj tej tawg qhov cub, cua sov rauv,
- Ceramic qhov kiln, cement kiln, thee burner,
- Rauv qhov rooj, pub qhib, steel furnaces, hlau ua rauv,
