Cov Cib Magnesia Carbon Ua Haujlwm Zoo Rau Kev Siv Hauv Kev Lag Luam Kub Hnyav

Rau cov lag luam ua hlau thiab cov hlau tsis yog ferrous uas tab tom nrhiav cov kev daws teeb meem refractory ruaj khov, pheej yig, zooCov cib magnesia carbon (MgO-C)sawv tawm ua qhov kev xaiv txhim khu kev qha tshaj plaws. Tsim los ntawm cov khoom siv zoo magnesia clinker, flake graphite, cov tshuaj antioxidants tshwj xeeb thiab cov resin binders muaj zog, peb cov magnesia carbon cib ua rau muaj kev ua tau zoo tshaj plaws hauv qhov kub thiab txias heev thiab cov chaw muaj tshuaj lom neeg hnyav, ua cov khoom siv tseem ceeb rau cov cub tawg niaj hnub.

Qhov zoo tshaj plaws ntawm peb cov cib magnesia carbon yog lawv cov khoom siv refractory zoo heev. Lawv khav txog kev refractoriness siab heev, ruaj khov rau qhov kub ua haujlwm tas mus li saum 1700 ° C yam tsis muaj kev puas tsuaj lossis kev puas tsuaj ntawm cov qauv. Txawv ntawm cov cib refractory ib txwm muaj, kev sib xyaw ua ke ntawm magnesia thiab graphite coj kev tiv thaiv corrosion slag zoo heev thiab muaj peev xwm tiv thaiv kev nkag mus. Cov khoom graphite tsim ib qho chaw tsis ntub tiv thaiv cov hlau molten thiab ntau yam slags, zoo thaiv kev puas tsuaj ntawm alkaline thiab hlau nplua nuj slags, uas txo qhov hnav ntawm lub qhov cub hauv lub sijhawm ntev.

Kev tiv taus cua sov zoo heev yog lwm yam tseem ceeb ntawm peb cov khoom. Cov cub tawg hauv kev lag luam feem ntau ntsib kev kub thiab txias sai sai, uas yooj yim ua rau cib tawg thiab tawg. Peb cov cib magnesia carbon muaj cov coefficient nthuav dav thermal qis thiab cov thermal conductivity siab, uas tuaj yeem txo qhov kev ntxhov siab sab hauv, zam kev tev thiab tawg, thiab tswj kev ruaj khov ntawm cov qauv thaum muaj kev hloov pauv kub hnyav. Lub caij no, kev ntxiv cov tshuaj antioxidants ua haujlwm siab ua rau muaj kev tiv thaiv oxidation ntawm cov khoom carbon, ua rau lub neej ua haujlwm ntev dua ntawm cov cib hauv qhov chaw kub siab.

Siv tau dav hauv ntau yam kev lag luam, peb cov cib magnesia carbon yog qhov zoo tagnrho rau cov khoom tseem ceeb ntawm cov cua sov oxygen yooj yim (BOF), cov cua sov hluav taws xob arc (EAF), cov tais hlau thiab cov tundish casting tas mus li. Lawv kuj zoo meej rau kev sib xyaw cov cua sov smelting rau tooj liab, nickel thiab lwm yam hlau uas tsis yog ferrous, nrog rau cov khoom siv kub siab hauv kev tsim cement thiab lime. Kev txheeb xyuas kev lag luam qhia tau tias peb cov cib tuaj yeem txo lub sijhawm kho khoom siv los ntawm ze li ntawm 40% piv rau cov ntaub ntawv refractory ib txwm muaj, txhim kho kev ua haujlwm zoo heev thiab txo cov nqi ua haujlwm tag nrho.

Peb ua raws li cov qauv kev tswj xyuas zoo ntawm kev tsim khoom, muab cov cib magnesia carbon uas tsim tshwj xeeb rau ntau qib kom ua tau raws li ntau yam kev xav tau ntawm kev ua haujlwm. Txawm yog rau kev tsim cov hlau hnyav lossis cov chaw tsim khoom tshwj xeeb uas tsis yog hlau, peb cov khoom muaj kev ua haujlwm ruaj khov, ruaj khov thiab tus nqi tsim nyog. Xaiv peb cov cib magnesia carbon zoo tshaj plaws los txhim kho koj lub tshuab cua sov thiab ua kom koj cov txiaj ntsig ntau tshaj plaws ntawm kev tsim khoom hauv kev lag luam.
