Magnesia carbon bricks yog ib yam ntawm unburned carbon composite refractory, uas yog tsim nrog magnesium oxide ntawm alkaline oxide nrog high-melting-point (2800 ℃), thiab carbon cov ntaub ntawv uas siab melting point uas yog ib qho nyuaj rau eroded los ntawm lub cub tawg slag raws li lub raw cov ntaub ntawv, thiab ntxiv txhua yam uas tsis yog-oxides additives thiab carbon binding tus neeg saib xyuas. Magnesia carbon cib muaj cov yam ntxwv ntawm qhov tsis tshua muaj porosity, slag yaig tsis kam, thermal shock tsis kam thiab siab kub siab zog. Raws li ib hom kev sib xyaw refractory, magnesia carbon hluav taws cib siv lub zog slag corrosion ntawm magnesia thiab siab thermal conductivity thiab qis expansibility ntawm carbon zoo, tuaj yeem ua rau qhov loj tshaj qhov tsis zoo ntawm qhov tsis zoo ntawm magnesia.
Magnesia carbon bricks cov ntsiab lus tseem ceeb yog magnesium oxide thiab carbon, ntawm cov ntsiab lus magnesium oxide yog 60 ~ 90% thiab cov ntsiab lus carbon yog 10 ~ 40%. Cov khoom zoo no yog ua los ntawm cov purity magnesia particle, carbon cov khoom, tar, suab los yog cob raws li raw cov ntaub ntawv los ntawm kub kub ci. Yog li magnesite carbon bricks muaj cov khoom ntawm slag corrosion kuj, thermal shock resistance, thermal conductivity thiab lwm yam.
Raws li kev sib xyaw ua ke txias nrog cov khoom sib txuas tar binding tus neeg sawv cev ua kom tawv thiab tau txais lub zog tsim nyog, yog li tsim cov isotropous vitric carbon. Magnesia carbon bricks yog tsim los ntawm pitch binding tus neeg sawv cev, uas muaj siab dua kub plasticity vim yog tsim anisotropic graphitization coke qauv nyob rau hauv lub suab carbonation txheej txheem. Cov pa roj carbon zoo li no tsis qhia cov thermoplasticity uas tuaj yeem tshem tawm cov kev ntxhov siab hauv cov txheej txheem ntawm kev tua hluav taws lossis kev ua haujlwm.

Magnesia carbon bricks yog tsuas yog siv rau hauv ob sab phlu converter, hluav taws xob-arc rauv thiab ncaj qha hluav taws xob arc rauv, slag kab ntawm steel ladle thiab lwm txoj hauj lwm. thiab tseem tuaj yeem siv rau cov pa taws yooj yim, cov kab slag ntawm ladle rauv thiab qhov chaw kub ntawm hluav taws xob arc rauv.
RS refractory Hoobkas raws li ib qho ntawm cov ua lag luam magnesite carbon bricks chaw tsim tshuaj paus, muaj peev xwm muab tau zoo magnesia carbon cib rau cov neeg muas zaub nrog cov kws txawj engineers, advanced ntau lawm technology thiab zoo ua ntej muag thiab tom qab-muag kev pab cuam. RS refractory Hoobkas tau tshwj xeeb hauv magnesite carbon hluav taws cib rau ntau tshaj 20 xyoo. Yog tias koj muaj qee qhov kev thov ntawm magnesia carbon cib, tiv tauj peb dawb, peb qhov muag yuav teb koj thawj zaug.
