Hauv kev lag luam steel, xaiv cov khoom siv raw khoom zoo tshaj yog qhov kev txiav txim siab tshaj plaws xwb -nws yog ib qho teeb meem ntawm kev ua haujlwm ntawm tus nqi, lub neej hauv lub cub tawg, thiab kev ntseeg tau ntawm kev ua haujlwm. Ob ntawm cov khoom siv dav siv siab tshaj -purity magnesium oxide (MgO) yogTuag hlawv Magnesia(DBM) thiab Fused Magnesia (FM). Ob qho khoom siv muaj cov khoom zoo heev refractory, tab sis lawv txawv ntawm txoj kev tsim khoom, qib purity, thiab cov yam ntxwv ua haujlwm. Tab sis qhov twg yog qhov zoo dua rov qab los ntawm kev nqis peev (ROI) rau cov neeg tsim khoom steel?
Tuag Burned Magnesia (DBM) yog dab tsi?
Tuag Burned Magnesia yog tsim los ntawm calcining ntuj magnesite ntawm 1,800-2,000 degree. Cov txheej txheem yields ib tug ntom, crystalline khoom nrog siab refractoriness, muaj zog bulk ntom, thiab zoo heev tsis kam mus rau hauv paus slags.
Cov yam ntxwv tseem ceeb: Kev ruaj ntseg siab, kev tiv thaiv corrosion, tus nqi - ua haujlwm tau zoo.
Daim Ntawv Thov: Basic Oxygen Furnaces (BOF), Hluav Taws Xob Arc Rauv (EAF), steel ladles, thiab cement kilns.
Fused Magnesia (FM) yog dab tsi?
Fused Magnesia, ntawm qhov tod tes, yog tsim nyob rau hauv hluav taws xob arc rauv ntawm 2,800℃lossis siab dua, tsim cov pob zeb periclase loj nrog qhov ntom ntom thiab purity.
Main nta: Superior tshuaj stability, porosity tsawg heev, zoo heev corrosion kuj.
Cov ntawv thov: Cov khoom lag luam siab tshaj plaws, cov rooj vag swb, nozzles, thiab kev lag luam uas xav tau qhov siab tshaj plaws tiv thaiv cov slags hnyav.
Qhov txawv ntawm DBM thiab FM
Kev tsim khoom
Kev tsim khoom ntawm DBM suav nrog calcining ntuj magnesite nyob rau hauv teb kilns los yog ncej kilns ntawm 1600-2000 degree. FM ntau lawm suav nrog hluav taws xob arc melting ntawm magnesite ntawm 2800-3000 degree, ua raws li kev tswj kom txias. Ob qho txheej txheem yuav tsum tau tswj xyuas nruj kom ntseeg tau tias kev ua haujlwm zoo ib yam thiab ua haujlwm zoo.
Qhov kev xaiv twg muab ROI zoo dua?
DBM muab tus nqi zoo dua - qhov ua tau zoo. Rau cov txheej txheem steelmaking thiab cov txheej txheem refractory cib, DBM muab kev ruaj khov txaus ntawm tus nqi qis dua.
FM muab kev pabcuam ntev dua nyob rau hauv siab - thaj chaw cuam tshuam xws li lub rooj vag swb thiab lub taub hau. Txawm hais tias nws tus nqi siab dua, FM txo qis zaus hloov pauv thiab lub sijhawm poob qis, uas tuaj yeem ua pov thawj rau kev nqis peev hauv cov chaw tshwj xeeb.
Rau feem ntau cov nroj tsuag steel, lub tswv yim zoo tshaj plaws yog los ua ke ob qho khoom siv -siv DBM rau bulk refractory linings thiab FM rau siab - hnav qhov tseem ceeb. Qhov kev sib xyaw ua ke no ua kom muaj kev txuag nyiaj thiab kev nyab xeeb ntawm kev ua haujlwm.
Cov neeg yuav khoom thoob ntiaj teb tab tom nrhiav ntau dua rau cov neeg xa khoom uas tuaj yeem muab cov khoom lag luam ruaj khov, tus nqi sib tw, thiab ntawm - sijhawm xa khoom ntawm DBM thiab FM. Nrog kev tswj hwm nruj thiab kev muaj peev xwm logistics thoob ntiaj teb, kev nrhiav los ntawm tus neeg muag khoom ntseeg siab kom ntseeg tau:
Raws li MgO cov ntsiab lus thiab ntom
Tsawg tus nqi ntawm cov tswv cuab
Ua raws li cov qauv kev lag luam steel
Ntiaj teb no muab saw hlau kev ntseeg tau
Ob Qhov Tuag Burned Magnesia thiab Fused Magnesia yog qhov tseem ceeb rau kev lag luam steel. DBM tseem yog tus nqi nyiam tshaj -kev daws teeb meem zoo rau cov cib refractory dav dav, thaum FM yog qhov zoo tagnrho rau cov cheeb tsam tseem ceeb uas yuav tsum tau ua kom ntev tshaj plaws. Xaiv qhov sib xyaw kom raug tsis yog tsuas yog txhim kho qhov ua tau zoo ntawm lub tshuab hluav taws xob tab sis kuj tseem muab ROI zoo dua rau cov neeg tsim khoom thoob ntiaj teb.
