Kev lag luam steel sawv ua tus caj qaum ntawm lub ntiaj teb kev tsim kho vaj tse, tsis tau nws ua haujlwm nyob rau hauv ib qho ntawm cov huab cua kub hnyav tshaj plaws hauv ntiaj teb. Los ntawm kev kub siab ntawm cov hlau smelting mus rau qhov tseeb ntawm cov hlau casting, cov cuab yeej tseem ceeb xws li hloov pauv, hluav taws xob arc rauv, thiab lub tshuab hluav taws xob tawg ntsib kev ntxhov siab tsis tu ncua: lawv yuav tsum ua siab ntev rau qhov kub thiab txias uas feem ntau tshaj 1,600 ° C, ua ke nrog aggressive yaig los ntawm molten slag thiab scalding hlau. Qhov kev mob hnyav no tso qhov kev xav tau tsis sib xws ntawm cov khoom siv hluav taws xob - cov txheej txheem tiv thaiv uas tiv thaiv cov cuab yeej los ntawm kev puas tsuaj - thiab ntawm txhua qhov kev xaiv,magnesium-chromium cibtawm los ua qhov kawg, txhim khu kev qha daws.
Magnesium-chromium bricks tshuav lawv txoj haujlwm tsis muaj kev sib tw hauv kev lag luam steel rau peb lub hauv paus, cov khoom tsis zoo uas hais txog txhua qhov kev mob loj ntawm cov hlau kub kub ntau lawm. Ua ntej, lawv qhov tshwj xeeb tiv thaiv hluav taws yog qhov hloov pauv rau kev nyab xeeb thiab kev ua haujlwm: nrog rau qhov ntsuas qhov ntsuas kub zoo tshaj 1,700 ° C, cov cib no tuav lawv txoj kev ncaj ncees txawm tias nyob rau hauv qhov kub tshaj plaws ntawm steelmaking furnaces. Tsis zoo li cov ntaub ntawv refractory tsis zoo uas yuav muag los yog yaj thaum tshav kub kub, magnesium-chromium cib tshem tawm qhov kev pheej hmoo ntawm cov khoom siv tsis ua hauj lwm tam sim ntawd, uas tuaj yeem nres cov kab ntau lawm thiab ua rau cov nqi qeeb. Thib ob, lawv cov slag superior tiv thaiv ncaj qha tackles ib qho ntawm cov kev lag luam steel qhov kev sib tw loj tshaj plaws. Ua los ntawm high-purity magnesium oxide thiab chromium oxide, cov cib tsim ib qhov ntom ntom, impermeable barrier uas repels ob alkaline thiab acidic slags - feem ntau byproducts ntawm steel ntau lawm uas noj tam sim ntawd nyob rau hauv cov pa hauv ob sab phlu. Qhov kev tiv thaiv no tau txuas ntxiv rau lub tshuab hluav taws xob hauv lub neej los ntawm 30% lossis ntau dua piv rau cov qauv refractories, txo cov nqi hloov pauv ntau zaus thiab txo qis qis qis. Thib peb, lawv cov thermal shock stability zoo ua kom zoo sib xws thaum lub sijhawm ua haujlwm tseem ceeb. Thaum lub cub tawg pib los yog kaw, qhov kub thiab txias tuaj yeem hloov los ntawm ntau pua degrees hauv lub sijhawm luv luv - qhov kev ntxhov siab uas ua rau feem ntau cov cib tawg lossis tawg. Magnesium-chromium bricks, txawm li cas los xij, nqus cov kev hloov pauv no tsis muaj zog, ua kom cov ntaub ntawv tsis zoo thiab kev tsim khoom ua haujlwm zoo yam tsis muaj kev cuam tshuam.
Cov khoom muaj txiaj ntsig zoo no ua rau magnesium-chromium bricks indispensable nyob rau hauv txhua txhua theem tseem ceeb ntawm steelmaking, los ntawm raw cov ntaub ntawv mus rau zaum kawg casting. Nyob rau hauv converters thiab hluav taws xob arc rauv, qhov twg hlau yog melted thiab refined, cov cib kab nyob rau hauv lub puab phab ntsa, enduring ncaj scouring los ntawm churning molten steel thiab corrosive slag. Qhov kev tiv thaiv no tso cai rau cov cub tawg ua haujlwm ntawm qhov ua tau zoo tshaj plaws rau kev ncua ntev, txhawb nqa cov khoom siv hlau niaj hnub. Nyob rau hauv ladles - cov hlab ntsha loj uas thauj cov hlau molten los ntawm lub cub tawg mus rau lub tshuab casting - magnesium-chromium bricks ua raws li cov ntaub ntawv muaj zog. Lawv tiv thaiv kom tsis txhob muaj cua sov uas yuav cuam tshuam cov hlau zoo thiab thaiv qhov muaj peev xwm to, kom ntseeg tau tias cov hlau molten ncav cuag nws cov theem tom ntej hauv qhov zoo tshaj plaws rau kev ua haujlwm qis xws li dov lossis forging. Txawm hais tias nyob rau hauv qhov cub tawg, lub plawv ntawm cov hlau tsim, cov cib no tiv thaiv cov cheeb tsam sab saud thiab sab qis los ntawm kev sib xyaw ua ke ntawm cov roj kub kub (txog 2,000 ° C) thiab molten slag, txhawb nqa mus ntev, ruaj khov ua haujlwm uas tseem ceeb heev rau cov khoom siv hlau zoo ib yam.
Rau cov tuam txhab steel siv zog los txhawb kev tsim khoom, txiav cov nqi ua haujlwm, thiab tswj kev sib tw, xaiv cov khoom zoo magnesium-chromium bricks tsis yog ib qho kev xaiv - nws yog qhov tsim nyog. Peb cov magnesium-chromium bricks yog engineered nrog nruj zoo tswj, siv hwm raw cov ntaub ntawv uas tau mus soj ntsuam nruj raws li thoob ntiaj teb cov qauv kev lag luam. Kev ntseeg siab los ntawm cov thawj coj steel nroj tsuag thoob plaws Asia, Europe, thiab North America, peb cov khoom muaj cov ntaub ntawv pov thawj ntawm kev xa cov kev ua tau zoo, txawm tias nyob rau hauv qhov chaw tsim khoom xav tau tshaj plaws. Koom tes nrog peb niaj hnub no, thiab cia peb cov kev lag luam-ua hluav taws-tiv thaiv kev daws teeb meem ntxiv dag zog rau koj cov txheej txheem steelmaking, txo qis qis qis, thiab pab koj ua kom muaj kev vam meej, mus ntev.
