Cov khoom siv refractoryyog cov khoom tseem ceeb ntawm ntau cov txheej txheem kev lag luam, muab kev kub siab ua haujlwm, durability, thiab thermal rwb thaiv tsev. Cov ntaub ntawv no tuaj yeem txhais tau tias yog cov khoom uas tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj degrading lossis melting.
Muaj ntau ntau hom khoom siv refractory, txhua tus muaj cov khoom sib txawv thiab kev siv. Qee cov khoom siv refractory muaj xws li firebricks, ceramics fibers, castables, thiab refractory hlau. Txhua yam ntawm cov ntaub ntawv no muaj qhov zoo thiab qhov tsis zoo, nyob ntawm cov txheej txheem tshwj xeeb uas lawv tau siv.
Piv txwv li, firebricks yog ua los ntawm cov ntaub ntawv xws li av nplaum thiab alumina, thiab yog siv los ua ib qho yooj yim-rau-manipulate duab nyob rau hauv high-temperature daim ntaub ntawv xws li furnaces thiab kilns. Ceramic fibers yog ua los ntawm iav los yog ceramic cov ntaub ntawv, thiab yog siv los ua rwb thaiv tsev nyob rau hauv high-temperature ib puag ncig uas qhov chaw yog ib tug txwv. Castables yog tsim los ntawm refractory aggregates thiab binders, thiab yog siv thaum muaj kev cai zoo li yuav tsum tau nyob rau hauv high-temperature daim ntaub ntawv. Cov hlau refractory, xws li tungsten, molybdenum, thiab niobium, yog siv rau hauv cov ntawv thov uas kub kub lub zog thiab tiv thaiv corrosion yog qhov tseem ceeb.
Cov ntaub ntawv refractory yog qhov tseem ceeb hauv ntau cov txheej txheem kev lag luam, thiab lawv cov khoom tuaj yeem ua raws li cov kev xav tau tshwj xeeb. Lawv tau siv ntau hauv kev lag luam, suav nrog steelmaking, glassmaking, ceramics, cement, thiab petrochemicals. Nrog rau lawv cov khoom tshwj xeeb thiab kub ua haujlwm siab, cov ntaub ntawv refractory ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov kev lag luam los ntawm kev ua kom sov siab dua, ua kom muaj txiaj ntsig zoo, thiab txo kev cuam tshuam ib puag ncig.
Zuag qhia tag nrho, cov ntaub ntawv refractory yog ib feem tseem ceeb ntawm ntau cov txheej txheem kev lag luam, thiab kev nce qib hauv lawv txoj kev loj hlob thiab kev siv tau txuas ntxiv txhim kho ntau yam kev lag luam. Vim li no, cov ntaub ntawv refractory tseem yuav yog qhov tseem ceeb hauv kev nce qib ntawm kev lag luam rau xyoo tom ntej.
