Hauv kev lag luam steelmaking, steel ladle yog lub nkoj tseem ceeb uas nqa, tuav, thiab kho cov hlau molten ntawm cov txheej txheem ntau lawm. Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau qhov zoo ntawm cov hlau, kev tsim khoom, thiab cov nqi ua haujlwm. Txawm li cas los xij, cov hlau molten nce mus txog qhov kub siab txog 1,600 ° C lossis ntau dua, thiab nws kuj cuam tshuam nrog cov slags hnyav, kev yaig, thiab thermal shock - ua rau muaj teeb meem loj rau cov ntaub ntawv refractory hauv ob sab phlu steel ladle. Qhov no yog qhov twgmagnesium carbon cib(MgO-C bricks) sawv tawm raws li cov kev daws teeb meem kawg, xa cov khoom tsis sib haum xeeb thiab kev ntseeg siab rau kev ua haujlwm steel.
Vim li cas Magnesium Carbon Bricks yog qhov tseem ceeb rau Steel Ladles
Steel ladles xav tau cov ntaub ntawv refractory uas tuaj yeem tiv taus huab cua yam tsis muaj kev cuam tshuam kev ua haujlwm. Ib txwm siv cov cib refractory feem ntau ua tsis tau raws li qhov xav tau no, ua rau muaj kev hloov pauv ntau zaus, kev tsim khoom poob qis, thiab cov nqi nce ntxiv. Magnesium carbon bricks, txawm li cas los xij, ua ke lub zog ntawm high-purity magnesia (MgO) thiab graphite los daws txhua qhov kev sib tw tseem ceeb ntawm steel ladle hauv ob sab phlu:
1. Exceptional High-Temperature Resistance
Magnesia, cov ntsiab lus tseem ceeb ntawm MgO-C cib, muaj qhov kub siab tshaj plaws melting point ntawm kwv yees li 2,800 ° C - deb tshaj qhov kub siab tshaj ntawm cov hlau molten. Thaum ua ke nrog graphite (cov khoom siv nrog thermal stability zoo), magnesium carbon bricks tswj lawv cov qauv kev ncaj ncees txawm tias nyob rau lub sij hawm raug rau 1,600 + ° C molten steel. Qhov kev tiv thaiv no tiv thaiv cib softening, deformation, los yog melting, kom ntseeg tau tias steel ladle tseem muaj kev nyab xeeb thiab ua haujlwm rau lub sijhawm ntev.
2. Superior Slag Corrosion Resistance
Molten steel yog nrog los ntawm slags-byproducts nplua nuj nyob rau hauv oxides (xws li SiO₂, Al₂O₃, thiab FeO) uas yog heev corrosive rau refractories. Magnesia nyob rau hauv MgO-C bricks reacts minimally nrog cov slags, tsim ib tug ntom, impermeable txheej ntawm cib nto uas thaiv ntxiv slag nkag. Tsis zoo li alumina-silica cib, uas yooj yim eroded los ntawm acidic los yog yooj yim slags, magnesium carbon cib tuav lawv cov tuab, txo qhov kev pheej hmoo ntawm ladle to.
3. Zoo heev Thermal Shock Resistancecov
Hlau ladles tau rov ua cua sov (kom tuav cov hlau molten) thiab txias (thaum lub sijhawm tu lossis lub sijhawm tsis ua haujlwm) - txheej txheem uas ua rau thermal shock. Yog hais tias cov ntaub ntawv refractory tsis tuaj yeem tiv taus qhov kub thiab txias, lawv yuav tawg, ua rau ua tsis tiav ntxov. Graphite nyob rau hauv magnesium carbon bricks ua raws li "buffer," absorbing thermal stress thiab tiv thaiv kev tawg. Qhov no txhais tau tias MgO-C cib tuaj yeem tiv taus ntau pua cua sov-txias lub voj voog yam tsis poob kev ua haujlwm, txuas ntxiv kev pab cuam lub neej ntawm steel ladle hauv ob sab phlu.
4. Txo tus nqi hnav thiab tu
Cov neeg siv khoom siv los ntawm cov hlau molten stirring, ladle txav, thiab slag scraping yog lwm qhov teeb meem loj rau steel ladle refractories. Magnesium carbon bricks muaj lub zog txhua yam thiab hardness, ua tsaug rau kev sib txuas ntawm cov hlau nplaum thiab graphite. Qhov no durability txo cib coj, cia lub ladle ua hauj lwm rau ntev ntawm relinings. Rau cov nroj tsuag steel, qhov no txhais tau tias tsis muaj sijhawm poob qis, cov nqi zog qis dua rau kev hloov cov khoom siv refractory, thiab ntau lub sijhawm ntau lawm.
Cov ntawv thov tseem ceeb ntawm Magnesium Carbon Cib hauv Steel Ladles
Magnesium carbon bricks tsis yog ib qho loj-haum-tag nrho cov kev daws teeb meem-lawv tau ua kom haum rau qhov sib txawv ntawm cov hlau ladle raws li cov theem kev ntxhov siab tshwj xeeb:
Ladle hauv qab thiab phab ntsa:Hauv qab thiab sab phab ntsa ntawm lub ladle yog nyob rau hauv ncaj qha, mus sij hawm ntev kev sib cuag nrog molten hlau thiab slags. Ntawm no, high-density magnesium carbon bricks (nrog 10-20% graphite cov ntsiab lus) yog siv los tiv thaiv corrosion thiab hnav.
Ladle Slag Line:Cov kab slag yog qhov chaw muaj kev phom sij tshaj plaws, vim nws ntsib kev cuam tshuam tsis tu ncua ntawm cov slags thiab thermal shock. Hwm magnesium carbon bricks (nrog cov ntsiab lus graphite siab dua thiab ntxiv cov tshuaj tiv thaiv antioxidants zoo li Al lossis Si) tau muab tso rau ntawm no los ua kom muaj kev pabcuam zoo tshaj plaws.
Ladle Nozzle thiab Kais Qhov:Cov cheeb tsam no yuav tsum tau cib nrog cov thermal conductivity thiab yaig tsis kam los xyuas kom meej molten steel ntws. Tshwj xeeb MgO-C bricks nrog nplua-grained magnesia yog siv los tiv thaiv clogging thiab txuas lub neej nozzle.
Cov txiaj ntsig rau cov nroj tsuag steel: Tshaj li Durability
Xaiv magnesium carbon bricks rau steel ladle linings muab cov txiaj ntsig kev lag luam rau cov tuam txhab steel:
Txhim kho Steel Zoo:Los ntawm kev tiv thaiv refractory yaig, MgO-C cib txo qhov kev pheej hmoo ntawm refractory hais kis kab mob molten steel - kom ntseeg tau cov tshuaj muaj pes tsawg leeg thiab tsawg tsis xws luag nyob rau hauv cov khoom steel tiav.
Kev txuag hluav taws xob:Lub siab thermal conductivity ntawm graphite hauv MgO-C cib pab khaws cov cua sov hauv lub ladle, txo qhov xav tau rov ua cua sov molten hlau. Qhov no txo qis roj noj thiab carbon emissions ..
Ntev Ntev Kev Pabcuam Lub Neej: Qhov nruab nrab, magnesium carbon cib hauv ob sab phlu kav ntev li 2-3 zaug ntev dua li cov ntaub ntawv refractory. Rau ib tug raug steel ladle, qhov no txhais tau tias relining ib zaug ib zaug txhua 6-12 lub hlis, piv rau 2-3 zaug ib xyoos nrog rau lwm yam ntaub ntawv.
Xaiv High-Quality Magnesium Carbon Cib rau Koj Cov Hlau Ladles
Tsis yog tag nrho magnesium carbon bricks yog tsim sib npaug. Txhawm rau kom ua tau zoo tshaj plaws, nrhiav cov khoom siv nrog:
