Cov ntaub ntawv refractory xa mus rau cov ntaub ntawv uas tuaj yeem tswj kev ruaj ntseg thiab corrosion kuj ntawm qhov kub thiab txias. Lawv feem ntau siv hauv metallurgy, tshuaj lom neeg kev lag luam, cov khoom siv hauv tsev thiab lwm yam kev lag luam, thiab yog ib qho ntawm cov ntaub ntawv tseem ceeb hauv kev tsim khoom.
Cov ntaub ntawv refractory yog dav siv nyob rau hauv ntau yam, ntawm cov ceramic fiber, silicate fiber, alumina, silica cib, thiab lwm yam. tau dhau los ua cov neeg sawv cev tseem ceeb. Ceramic fibers yog dav siv nyob rau hauv cov teb xws li hlau melting thiab high-temperature tshuaj tiv thaiv vim lawv zoo heev zog xws li tsawg ntom thiab thermal kuj. Silicate fiber yog haum rau siv nyob rau hauv hnyav ib puag ncig xws li kub thiab kub siab, thiab muaj zoo corrosion kuj thiab thermal stability. Alumina refractory khoom, raws li qib high-qib ceramic khoom, yog dav siv nyob rau hauv industrial high-kub kilns, pleev xim rau thiab lwm yam teb, thiab tau tsim sai heev. Raws li ib qho ntawm cov neeg sawv cev ntawm cov ntaub ntawv refractory, silica bricks yog dav siv nyob rau hauv zus tau tej cov ceramics, cement, steel, thiab lwm yam, thiab muaj zoo kub kub, corrosion, thiab hnav tsis kam.
Nyob rau hauv cov txheej txheem ntawm cov khoom siv refractory, muaj ntau yam ntsiab lus uas yuav tsum tau them sai sai rau. Thawj qhov nthuav dav yog kev tswj xyuas cov khoom zoo. Thaum lub sij hawm tsim cov txheej txheem, cov khoom siv raw yuav tsum tau kuaj xyuas kom zoo thiab kuaj xyuas kom ntseeg tau tias cov khoom zoo raws li qhov yuav tsum tau ua. Qhov thib ob nthuav dav yog ua pwm. Cov khoom siv refractory pwm ua yuav tsum muaj kev tswj xyuas kom paub meej tias cov duab thiab qhov loj ntawm cov pwm ua tau raws li qhov yuav tsum tau ua. Qhov thib peb nthuav dav yog kev tswj cov txheej txheem ntau lawm. Thaum lub sij hawm tsim cov txheej txheem, cov txheej txheem kev khiav hauj lwm cov cuab yeej thiab cov txheej txheem kev ruaj ntseg yuav tsum tau ua raws li nruj me ntsis raws li qhov ntsuas kub thiab siab thaum lub sij hawm tsim cov txheej txheem yuav tsum tau tswj kom muaj kev ruaj ntseg thiab kev ruaj ntseg ntawm cov txheej txheem ntau lawm.
Cov ntaub ntawv refractory yog cov ntaub ntawv tseem ceeb hauv kev tsim khoom, thiab lawv qhov zoo thiab kev siv ntau yam ua lub luag haujlwm tseem ceeb hauv kev tsim khoom. Peb yuav tsum ntxiv dag zog rau kev tshawb fawb thiab kev nkag siab ntawm daim teb no thiab pab txhawb kev tsim kho kev lag luam.
