Magnesia-raws li refractory cib yog qhov zoo rau kev tsim cov hlau vim muaj ntau yam tseem ceeb thiab cov khoom uas haum rau qhov xav tau ntawm cov txheej txheem steelmaking. Nov yog vim li cas lawv thiaj suav tias yog qhov zoo tshaj plaws rau kev lag luam no:
Siab Refractoriness: Magnesia bricks nthuav tawm cov refractoriness zoo heev, muaj peev xwm tiv taus qhov kub siab heev uas feem ntau pom hauv kev ua haujlwm steel, suav nrog hauv cov hlau ladle, cov pa hluav taws xob yooj yim (BOF), thiab hluav taws xob arc rauv (EAF).
High Melting Point:Magnesia muaj qhov siab melting point, tso cai rau cov cib no khaws lawv lub zog thiab cov qauv txawm tias nyob rau hauv cov cua sov uas tsim los thaum lub sij hawm tsim cov hlau.
Zoo heev thermal conductivity: Magnesia-raws li refractory bricks muaj kuj thermal conductivity. Hauv steelmaking, qhov kev tswj xyuas qhov kub thiab txias yog qhov tseem ceeb, cov cib no pab txhawb kev hloov pauv ntawm cov cua sov hauv cov cub tawg thiab lwm yam khoom siv.
Basicity thiab Alkalinity:Magnesia bricks nthuav tawm qhov yooj yim refractoriness thiab muaj kev tiv thaiv zoo rau alkaline slags thiab yooj yim steelmaking ib puag ncig, xws li cov pom hauv BOFs. Lawv tiv thaiv cov tshuaj tiv thaiv nrog cov ntsiab lus yooj yim, ua kom lub neej ntev thiab ruaj khov hauv cov xwm txheej zoo li no.
Resistance rau Thermal Spalling:Cov cib no tsis tshua muaj thermal spalling lossis cracking thaum raug hloov kub ceev, uas yog ib qho tshwm sim hauv cov txheej txheem steelmaking.
Cov ntsiab lus hlau tsawg: Magnesia bricks feem ntau muaj cov ntsiab lus hlau tsawg, txo qhov kev pheej hmoo ntawm cov hlau tuaj tos hauv cov hlau yaj. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas muaj cov kab mob hlau muaj kev txhawj xeeb.
Flexibility thiab Ductility: Magnesia-raws li cib tuaj yeem nthuav tawm qee qhov kev hloov pauv nyob rau hauv qhov kub thiab txias, muab kev tiv thaiv rau cov neeg kho tshuab kev ntxhov siab thiab pab kom haum rau kev nthuav dav thiab kev cog lus nyob rau hauv qhov cub thiab cov khoom siv refractory.
Ntau yam: Lawv tuaj nyob rau hauv ntau yam compositions thiab cov ntaub ntawv, tso cai rau tailored kev daws teeb meem rau ntau qhov chaw ntawm steelmaking txheej txheem, xws li converters, ladles, thiab nruam casting daim ntaub ntawv.
Vim yog cov yam ntxwv no, magnesia-based refractory bricks ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau, ua rau kev ua tau zoo, kev ntseeg tau, thiab ua haujlwm ntev ntawm cov ntaub ntawv refractory hauv steelmaking cov cuab yeej thiab cov chaw. Lawv muaj peev xwm tiv taus qhov kub thiab txias, tiv thaiv cov tshuaj lom neeg, thiab tswj kev ua haujlwm zoo ua rau lawv xaiv qhov tseem ceeb rau ntau yam kev siv hauv kev lag luam steel.
