Magnesia carbon cib yog cov khoom siv kub-kub refractory, feem ntau yog siv hauv cov chaw ua haujlwm kub xws li metallurgy thiab furnaces. Nws cov txheej txheem tsim khoom feem ntau suav nrog kev xaiv khoom, sib tov, nias, ziab thiab tua.
1. Xaiv cov khoom siv
Cov ntaub ntawv tseem ceeb ntawm magnesia carbon bricks yog cov pob zeb zoo magnesia, graphite, thiab lwm yam. Thaum lub sij hawm xaiv cov khoom, yuav tsum tau them nyiaj rau qhov zoo ntawm cov ntaub ntawv raw los xyuas kom meej qhov zoo ntawm cov khoom tiav. Nyob rau tib lub sijhawm, qee cov tshuaj ntxiv yuav tsum tau ntxiv raws li qhov xav tau tiag tiag los txhim kho kev ua haujlwm ntawm cov khoom.
2. Sib tov
Cov khoom siv raw uas tau xaiv yuav tsum sib tov. Lub hom phiaj ntawm kev sib xyaw yog kom tso cai rau ntau yam khoom siv raw khoom kom muaj kev sib xyaw ua ke thiab sib npaug sib npaug. Cov txheej txheem sib xyaw tshwj xeeb yog feem ntau muab ntau yam khoom siv raw rau hauv lub tov khoom raws li ib qho kev faib ua feem, thiab tom qab ntawd do cov khoom siv raw ntawm qhov kub ceev kom ua tiav lub xeev sib xyaw.
3. txo
Tom qab kev sib xyaw ua tiav, cov khoom siv raw tau txais hauv cov hmoov hmoov, uas yuav tsum tau nias. Lub hom phiaj ntawm kev nias yog tsim cov ntaub ntawv raw rau hauv cov duab blanks los muab cov xwm txheej rau cov txheej txheem tom ntej firing. Txoj kev nias feem ntau siv txhaj tshuaj molding, qhuav molding, ntub molding thiab lwm yam txheej txheem. Nyob ntawm daim ntawv nias, lub fineness ntawm molded dawb paug ntawm cov khoom kuj yuav txawv.
4. Qhuav
Tom qab nias thiab molding, lub resulting molded dawb paug muaj noo noo ntau dhau. Yog tias nws raug rho tawm haujlwm ncaj qha, cov xwm txheej txaus ntshai xws li tawg tuaj yeem tshwm sim tau yooj yim. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau qhuav cov molded dawb paug kom maj mam evaporate cov dej, kom cov molded dawb paug yog qhuav thiab ruaj, thiab ua tiav ib tug zoo firing nyhuv.
5. Kev tua
Cov txheej txheem tua hluav taws ntawm cov qhuav molded dawb paug yog ib kauj ruam tseem ceeb hauv tag nrho cov txheej txheem. Cov kauj ruam no muaj qhov cuam tshuam tseem ceeb ntawm cov khoom ntawm cov khoom tsim tawm magnesia carbon cib. Qhov kub ntawm qhov hluav taws kub feem ntau yog siab tshaj 1350 degree thiab siv sij hawm ob peb teev kom ua tiav cov txheej txheem tsim khoom zoo tshaj plaws ntawm magnesia carbon cib. Tom qab cov kauj ruam no tiav, cov magnesia carbon cib tuaj yeem muab tso rau hauv kev ua lag luam.
Nyob rau hauv luv luv, zus tau tej cov magnesia carbon bricks yuav tsum tau ceev faj tswj ntawm txhua qhov txuas, los ntawm kev xaiv cov khoom, sib tov, nias, ziab kom qhuav. Txhua kauj ruam yuav tsum tau ua tib zoo tsim thiab ua siab ntev ua haujlwm kom tau txais cov khoom zoo siab magnesia carbon cib. Tsuas yog los ntawm kev tso siab rau kev siv tshuab zoo tshaj plaws tuaj yeem tsim tau ntau dua rau kev siv cov khoom zoo.
