Magnesia Castable: Qhov Kev daws teeb meem zoo tshaj plaws rau kev lag luam kub siab

Hauv lub ntiaj teb ntawm cov txheej txheem kev lag luam kub siab, qhov kev xav tau cov khoom siv refractory txhim khu kev qha, ruaj khov yog qhov tsis sib tham. Txij li kev ua hlau mus rau kev tsim cement, kev tsim iav mus rau cov hlau tsis yog ferrous, cov khoom siv ua haujlwm hauv qab qhov kub heev, xeb, thiab kev ntxhov siab ntawm lub tshuab xav tau cov ntaub ntawv uas tuaj yeem tiv taus cov xwm txheej hnyav thaum tswj hwm kev ruaj khov ntawm cov qauv. Qhov no yog qhov uasmagnesia castabletshwm sim los ua ib qho kev daws teeb meem uas hloov pauv qhov kev ua si - tsim los muab kev ua tau zoo tshaj plaws hauv qhov chaw nyuaj tshaj plaws.

Magnesia castable, ib hom monolithic refractory uas muaj cov magnesia (MgO) aggregates, binders, thiab additives, sawv tawm rau nws cov khoom sib xyaw ua ke uas daws tau cov kev xav tau tseem ceeb ntawm cov lag luam kub siab. Tsis zoo li cov cib refractories ib txwm muaj, magnesia castable muaj kev ywj pheej zoo dua hauv kev teeb tsa, kev hloov pauv mus rau cov duab nyuaj, thiab kev tiv thaiv thermal shock zoo dua, ua rau nws yog qhov kev xaiv zoo rau kev ua haujlwm niaj hnub uas nrhiav kev ua haujlwm zoo, lub neej ntev, thiab kev siv nyiaj tsawg.

Cov Kev Siv Tseem Ceeb Hauv Cov Lag Luam Tseem Ceeb

Qhov ua tau ntau yam ntawm magnesia castable ua rau nws tseem ceeb heev rau ntau yam kev lag luam, txhua tus tau txais txiaj ntsig los ntawm nws cov kev ua tau zoo:
Kev Lag Luam Hlau:Raws li lub hauv paus ntawm kev tsim cov hlau, magnesia castable yog siv dav hauv cov ladles, tundishes, hluav taws xob arc furnaces (EAF), thiab converter linings. Nws qhov siab refractoriness (melting point saum 2800 ° C) thiab zoo heev tiv taus cov hlau molten, slag, thiab flux corrosion ua kom lub neej ua haujlwm ntev, txo lub sijhawm tsis ua haujlwm rau kev txij nkawm thiab hloov pauv. Hauv cov txheej txheem casting tas mus li, magnesia castable's thermal stability tiv thaiv kev tawg thiab kev yaig, tiv thaiv qhov zoo ntawm cov hlau molten thiab txhim kho kev ua haujlwm ntau lawm.

Kev Tsim Khoom Siv Cement:Cov chaw ua cement ua haujlwm nyob rau hauv qhov kub thiab txias heev (txog li 1600 ° C) thiab cov xwm txheej abrasive los ntawm cov khoom siv raw thiab clinker. Magnesia castable yog siv rau hauv cov ntaub thaiv qhov cub, phab ntsa txias dua, thiab cov kav dej cua tertiary, qhov twg nws txoj kev tiv thaiv thermal cycling thiab alkali tawm tsam (ib qho teeb meem feem ntau hauv kev tsim cement) txo qhov hnav thiab ntev lub neej ua haujlwm ntawm qhov cub. Qhov no txhais tau tias cov nqi kho qis dua thiab cov cement zoo sib xws.

Cov hlau tsis yog hlau:Rau cov lag luam ua cov txhuas, tooj liab, thiab lwm yam hlau uas tsis yog ferrous, magnesia castable yog qhov zoo tagnrho rau crucibles, smelting furnaces, thiab launders. Nws qhov xwm txheej inert tiv thaiv kev ua qias tuaj ntawm cov hlau molten, thaum nws qhov siab ceev thiab porosity qis tiv thaiv kev nkag mus los ntawm cov molten slags thiab hlau, ua kom ntseeg tau tias muaj kev ua tau zoo hauv kev ua ntau thiab cov txheej txheem tsim khoom tas mus li.

Kev Tsim Khob Iav & Khoom Siv Ua Los Ntawm Av nplaum:Cov cub tawg iav thiab cov cub tawg ua los ntawm cov av nplaum xav tau cov khoom siv hluav taws xob uas tuaj yeem tiv taus qhov kub thiab txias ntev (1500–1800 ° C) thiab kev tawm tsam tshuaj lom neeg los ntawm cov iav yaj lossis cov iav ceramic. Magnesia castable qhov kev tiv thaiv thermal zoo heev thiab kev tiv taus cov chaw muaj silica ua rau nws tsim nyog rau cov yas hauv qhov cub, cov phab ntsa sab, thiab cov chav tsim hluav taws xob, txo qhov poob hluav taws xob thiab ua kom lub neej ntawm qhov cub ntev dua.
