Cov Khoom Siv Refractory Zoo Dawb Fused Alumina Grits nrog Cov Qauv Dawb
Dawb fused alumina / Dawb CorundumPob zebyog cov khoom siv refractory qib siab, uas ua los ntawm cov hmoov alumina zoo los ntawm kev yaj saum toj no 2000 ℃ hauv lub cub hluav taws xob arc thiab txias, muab faib ua ntau qhov loj me ntawm cov noob. Cov alumina dawb fused yog cov khoom siv tseem ceeb rau kev tsim cov khoom siv refractory tsis zoo thiab cov duab.
Alumina dawb fused yog ua los ntawm cov hmoov alumina uas muaj cov sodium tsawg thiab muaj cov khoom qab zib ntau los ntawm kev yaj ntawm qhov kub siab, txias cov khoom siv crystallization, thiab tom qab ntawd zom. Cov xuab zeb alumina dawb fused raug tswj hwm nruj kom khaws cov noob sib faib thiab cov tsos zoo ib yam.
Feem ntau siv rau hauv ladle castables, cov ntaub ntawv khiav hlau, cov ntaub ntawv sib xyaw ua ke refractory gunning thiab lwm yam khoom monolithic refractory; Rau cov ntaub ntawv refractory zoo li tus, nws yog siv rau hauv cov khoom siv raw zoo ntawm corundum cib, corundum mullite, refining steel porous plug cib, phom txau, steelmaking thiab kev lag luam casting tas mus li.
Nws kuj tseem siv tau ua cov ntaub ntawv rau polishing, precision casting, txau thiab txheej, tshwj xeeb ceramics
