nta ntawm Lub teeb yuag siab alumina cib

Lub teeb yuag high-alumina cib feem ntau hu ua thermal rwb thaiv tsev refractory cib, tseem hu ua thermal rwb thaiv tsev refractory cib. Nws lub hom phiaj tseem ceeb yog rwb thaiv tsev kub thiab kev txuag hluav taws xob. Nyob rau hauv ib txwm siv, nws tsis yog nyob rau hauv kev sib cuag nrog qhov kub thiab txias ntawm lub cub tawg, thiab nws yog ib hom refractory cib khoom uas nyob ze rau ntawm lub cub tawg phab ntsa thiab muaj cua sov rwb thaiv tsev thiab kub preservation cuam tshuam.

Lub teeb yuag high-alumina cib yog ib qho zoo tshaj plaws tshav kub rwb thaiv tsev cov ntaub ntawv tam sim no. Nws muaj cov yam ntxwv ntawm siab compressive zog, tsis tshua muaj thermal conductivity, zoo rwb thaiv tsev kev ua tau zoo, thiab tus nqi qis. Nws tau dav siv nyob rau hauv ceramic tunnel kilns, cov menyuam kilns, thiab shuttle kilns. Hom kilns, phab ntsa kilns, kuj yog siv nyob rau hauv ntau yam cua sov rauv, coking furnaces thiab lwm yam thermal khoom, kho cua sov hauv ob sab phlu cov ntaub ntawv nyob rau hauv hlau thiab steel kev lag luam.

Lightweight high-alumina bricks kuj hu ua high-alumina rwb thaiv tsev cib. Cov khoom siv refractory hnav nrog alumina cov ntsiab lus siab dua 48%, feem ntau yog tsim los ntawm mullite thiab iav theem lossis corundum. Qhov ceev yog 0.4 ~ 1.35g / cm3. Lub porosity yog 66% ~ 73%, thiab lub zog compressive yog 1 ~ 8MPa. Thermal shock kuj zoo dua. Feem ntau, siab alumina bauxite clinker yog ntxiv nrog me me ntawm av nplaum, tom qab ua kom zoo, nws yog poured thiab zoo li tus nyob rau hauv daim ntawv ntawm av nkos los ntawm cov roj tiam txoj kev los yog ua npuas ncauj txoj kev, thiab tua ntawm 1300-1500 ° C. Qee zaum muaj alumina tuaj yeem siv los hloov ib feem ntawm bauxite clinker. Nws yog siv rau hauv ob sab phlu thiab tshav kub rwb thaiv tsev txheej ntawm masonry kilns, raws li zoo raws li qhov chaw uas tsis corroded thiab scoured los ntawm muaj zog high-temperature molten cov ntaub ntawv. Thaum nyob rau hauv kev sib cuag nrog cov nplaim taws, qhov kub ntawm qhov chaw yuav tsum tsis txhob siab tshaj 1350 ° C.
