Hauv kev lag luam uas qhov kub thiab txias siab, kev xeb ntawm cov tshuaj lom neeg, thiab kev hnav khaub ncaws tsis zam, kev xaiv cov khoom siv refractory zoo yog qhov tseem ceeb rau kev ua kom muaj kev ruaj khov ntawm kev ua haujlwm, txo cov nqi kho, thiab txhim kho kev ua haujlwm zoo. Ua ib qho kev daws teeb meem refractory uas tau sim sijhawm thiab pheej yig,cov cib av nplaum hluav tawstau dhau los ua thawj qhov kev xaiv rau ntau lub lag luam thoob ntiaj teb. Peb cov cib av nplaum hluav taws zoo tshaj plaws ua ke kev ua tau zoo heev, kev tswj hwm zoo nruj, thiab tus nqi sib tw, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau koj cov khoom siv kub siab.
Peb cov cib av nplaum hluav taws yog ua los ntawm cov av nplaum hluav taws uas muaj cov khoom huv si, kaolin, thiab cov khoom siv zoo xws li xuab zeb quartz thiab bauxite, uas muaj cov yam ntxwv zoo heev. Nrog rau cov alumina uas muaj li ntawm 30% txog 50%, lawv tuaj yeem tiv taus qhov kub thiab txias txog li 1550 ° C thiab tswj tau qhov ruaj khov txawm tias nyob rau hauv qhov chaw kub heev. Cov qauv ntom ntom ua kom muaj qhov porosity tsawg, ua kom muaj kev tiv thaiv rau acid slag thiab acidic gas corrosion - qhov zoo tshaj plaws rau kev lag luam uas siv cov khoom siv corrosive. Tsis tas li ntawd, cov khoom no ua rau muaj kev tiv thaiv thermal shock zoo heev, muaj peev xwm ua kom sov thiab txias sai yam tsis muaj kev tawg, yog li ua kom lub neej ua haujlwm ntawm cov cub tawg thiab lwm yam khoom siv ntev dua.
Qhov ua tau ntau yam yog lwm qhov tseem ceeb ntawm peb cov cib av nplaum hluav taws, uas siv dav hauv ntau qhov chaw ua haujlwm kub siab. Hauv kev lag luam hlau, lawv tuaj yeem siv rau cov ntaub thaiv ntawm cov cub tawg, cov qhov cub kub, thiab cov cub hluav taws xob, muab kev rwb thaiv tsev thiab kev tiv thaiv xeb. Hauv kev lag luam khoom siv hauv tsev, lawv ua haujlwm ua cov ntaub thaiv tseem ceeb rau cov cub tawg cement thiab cov cub tawg iav, ua kom ntseeg tau tias cov khoom siv ua haujlwm ruaj khov hauv qab qhov kub siab ntev. Cov lag luam petrochemical thiab lub zog kuj vam khom lawv rau cov ntaub thaiv cov khoom siv roj refining, boilers, thiab cov tshuaj reactors. Peb muab cov qhov ntau thiab tsawg thiab qib uas tau hloov kho, suav nrog cov qauv muaj zog thiab qis porosity, kom ua tau raws li cov kev xav tau tshwj xeeb ntawm cov khoom siv sib txawv thiab chaw ua haujlwm.
Nyob rau lub caij nyoog tam sim no ntawm kev tsim kho ntsuab thiab qis carbon, peb cov cib av nplaum hluav taws sawv tawm vim lawv cov txiaj ntsig zoo rau ib puag ncig. Kev siv cov thev naus laus zis sintering siab heev (kub sintering nyob ib puag ncig 1380 ° C), peb txhim kho kev ua haujlwm zoo thaum txo kev siv hluav taws xob. Hauv cov txheej txheem tsim khoom, peb suav nrog cov khoom siv pov tseg hauv kev lag luam xws li cov av nkos liab hloov kho thiab cov thee gangue, txo cov pa roj carbon thiab cov nqi khoom siv raw yam tsis muaj kev cuam tshuam zoo. Peb cov khoom ua raws li cov qauv ib puag ncig thoob ntiaj teb, pab koj ua tau raws li cov kev cai tsim khoom ntsuab thiab tau txais kev sib tw hauv kev lag luam thoob ntiaj teb.
Peb cog lus tias yuav muab kev txhawb nqa rau cov neeg siv khoom thoob ntiaj teb, txij li kev sab laj ua ntej muag thiab kev tsim khoom tshwj xeeb mus rau kev tshuaj xyuas zoo thaum lub sijhawm tsim khoom thiab kev pabcuam tom qab muag raws sijhawm, kom ntseeg tau tias muaj kev sib koom tes zoo thoob plaws. Peb cov cib av nplaum hluav taws tau raug xa tawm mus rau ntau lub tebchaws thiab thaj chaw, thiab cov neeg siv khoom hauv metallurgy, cement, iav, petrochemical thiab lwm yam kev lag luam ntseeg siab rau lawv cov khoom siv ruaj khov thiab pheej yig.
Tsis txhob cia cov khoom siv refractory tsis zoo cuam tshuam koj cov txheej txheem tsim khoom. Xaiv peb cov cib av nplaum hluav taws zoo kom txaus siab rau ntau qhov zoo ntawm kev ua haujlwm txhim khu kev qha, lub neej ntev thiab kev txuag nqi. Tiv tauj peb tam sim no kom paub ntau ntxiv txog cov lus qhia ntawm cov khoom, tau txais kev hais nqe dawb, thiab nrhiav kev daws teeb meem refractory zoo tshaj plaws rau koj cov kev xav tau kev lag luam.
