Mag Carbon Cib

Magnesia carbon bricksyog tsis yog- hlawv cov pa roj carbon monoxide hluav taws kub ua los ntawm siab purity fused magnesite thiab flake graphite ua cov ntaub ntawv tseem ceeb, tiv thaiv - oxidant additives yog siv. Phenolic resin yog siv los ua tus neeg sawv cev.

Magnesia carbon bricksFeem ntau yog siv los ua cov kab ua haujlwm ntawm cov pa oxygen hloov pauv yooj yim, Hluav taws xob Arc Rauv, steel refining furnaces, ladle slag cheeb tsam thiab lwm yam.

Magnesia carbon cibyog cov cib sib xyaw, yog li qhov zoo slag tsis kam ntawm magnesite thiab thermal conductivity & tsawg nthuav tus nqi ntawm graphite tau zoo ua ke, ua kom tsis tshua muaj kev ua haujlwm ntawm magnesite.

Kev cuam tshuam rau cov khoom ntawm magnesia bricks los ntawm raw cov ntaub ntawv

Cov khoom siv tseem ceeb rau magnesia carbon bricks yog magnesite. Qhov zoo ntawm magnesite cuam tshuam cov khoom ntawm magnesia carbon bricks heev, nws's tseem ceeb rau xaiv cov magnesite kom zoo rau cib ntau lawm. Muaj cov tuag hlawv magnesite thiab fused magnesite nrog cov yam ntxwv sib txawv.

Fused magnesite: Loj siv lead ua granularity, tsis muaj impurities cov ntsiab lus, cov ntsiab lus silicate tsawg, cov siv lead ua feem ntau ncaj qha sib txuas rau cov khoom ntom ntom nrog cov khoom siv thermal.

Tuag burnt magnesia: Crystal granularity yog me me, impurities thiab silicate cov ntsiab lus yog siab dua thaum piv rau fused magnesia, ncaj qha - bonded℃ntawm crystal yog tsawg.

Hais txog magnesia raw khoom, nrog rau cov tshuaj muaj pes tsawg leeg, feem ntau ntau dua ntom thiab loj siv lead ua granularity nyob rau hauv cov qauv yog txaus siab rau. Ua li no, feem ntau thaum peb txiav txim siab qhov zoo ntawm magnesite, peb muab cov ntsiab lus hauv qab no: 1. MgO cov ntsiab lus (Purity degree) 2. cov ntsiab lus thiab hom impurities, piv ntawm CaO/SiO2, thiab cov ntsiab lus ntawm B2O3. 3. Tej qhov ntom ntom, qhov loj thiab cov duab ntawm qhov pores thiab lwm yam ntawm magnesite.

Purity qib ntawm magnesite muaj kev cuam tshuam loj rau slag kuj ntawm magnesia carbon cib. Cov ntsiab lus MgO ntau dua, cov khoom tsis zoo thiab cov khoom silicate tsawg dua. Raws li qhov tshwm sim ntawm qhov ncaj qha - kev sib koom ua ke ntawm periclase siv lead ua siab dua, yog li cov slag tsis kam, corrosion resistance, yaig kuj siab dua. Cov impurities ntawm magnesia carbon bricks muaj xws li CaO, SiO3, Fe2O3 thiab lwm yam. Thaum cov impurities cov ntsiab lus tshwj xeeb tshaj yog cov ntsiab lus B2O3 siab, thermal kuj thiab kub zog yuav ua phem rau.
