Hauv kev lag luam steelmaking, qhov yooj yim oxygen rauv taws (BOF) ua lub luag haujlwm tseem ceeb hauv kev hloov cov ntaub ntawv raw rau hauv siab - steel zoo. Ib qho tseem ceeb tshaj plaws uas txiav txim siab qhov kev ua tau zoo, tus nqi ua haujlwm, thiab kev ua neej nyob ntawm BOF yog nws cov ntaub ntawv refractory. Xaiv txoj caioxygen rauv refractory brickstsis yog ib qho teeb meem ntawm durability; nws ncaj qha cuam tshuam rau steel zoo, kev siv hluav taws xob, thiab tag nrho cov nqi tsim khoom.
Vim li cas Refractory Lining tseem ceeb hauv lub cub tawg yooj yim?
Lub hauv paus refractory nyob rau hauv ib qho yooj yim oxygen rauv yog txheej tiv thaiv uas tiv thaiv lub plhaub hlau los ntawm huab cua kub thiab tshuaj lom neeg thaum lub sij hawm refining txheej txheem. Yog tias tsis muaj lub hauv paus txhim khu kev qha, lub cub tawg yuav raug kev puas tsuaj ntau zaus, kev kaw tsis tau npaj tseg, thiab cov nqi kho mob siab. High- zoo refractory hauv ob sab phlu ua kom ruaj khov kev ua haujlwm, txo cov slag nkag mus, thiab ua kom lub neej ntev ntawm kev sib tw, uas yog qhov tseem ceeb rau cov neeg tsim khoom steel nrhiav cov khoom tsim tawm thiab txo tus nqi ib tuj.
Hom Oxygen Rauv Cib Feem Ntau Siv?
Cov qib sib txawv ntawm cov pa hluav taws xob refractory cib yog tsim los ua kom tau raws li kev ua haujlwm hnyav ntawm BOF. Cov kev xaiv ib txwm muaj xws li:
Magnesia carbon bricks: Paub txog kev ua haujlwm siab thermal thiab muaj zog slag corrosion kuj.
Magnesia dolomite cib: Muab kev sib raug zoo nrog steelmaking slags thiab txuas rau lub qhov cub hauv ob sab phlu.
Direct-bonded magnesia bricks: Muab siab refractoriness thiab muaj zog structural stability nyob rau hauv load.
Txhua hom cib raug xaiv raws li cov nroj tsuag steel kev ua haujlwm, slag chemistry, thiab tus nqi -kev ua tau zoo.
Dab tsi yog cov txiaj ntsig ntawm kev siv cov pa oxygen rauv cib?
Txhim kho lub neej kev sib tw rau lub cub tawg: Lub sijhawm ntev ntawm cov txheej txheem yuav txo tau cov zaus relining.
Kev ua haujlwm ruaj khov thermal: Ua kom muaj cua sov hloov pauv zoo ib yam, txhim kho metallurgical tswj.
Txo downtime: Tsawg shutdowns nce steel cog productivity.
Cov nqi khiav lag luam qis dua: Kev siv cov refractory optimized txo qis tag nrho cov nqi tsim khoom steel.
Daim ntawv thov ntawm Refractory Solutions hauv Steelmaking
Nyob rau hauv BOF steelmaking, refractory hauv ob sab phlu yog siv nyob rau hauv ob peb cheeb tsam, nrog rau lub cub tawg hauv qab, sidewalls, thiab converter lub qhov ncauj. Txhua cheeb tsam ntsib kev ntxhov siab sib txawv, yuav tsum tau ua tib zoo tsim cov pa oxygen rauv refractory cib. Piv txwv li, magnesia carbon bricks yog nyiam nyob rau hauv slag kab cheeb tsam rau lawv zoo heev corrosion kuj, thaum magnesia dolomite bricks feem ntau siv los mus cuag tag nrho cov qhov cub.
Kev tsim khoom thiab kev tswj kom zoo ntawm Oxygen Rauv Cib
Kev ntseeg siab ntawm cov khoom siv refractory ua kom muaj kev tswj xyuas nruj hauv kev xaiv cov khoom siv raw, nias, tua, thiab tshuaj xyuas zaum kawg. Kev siv siab -purity magnesite, fused nplej, thiab cov khoom sib txuas ua ke tau lees paub zoo ib yam. Automated shaping thiab firing technologies kuj xyuas kom meej qhov ntom ntom thiab kev ua tau zoo, uas yog qhov tseem ceeb rau BOF efficiency.
Ntim thiab xa khoom
Txhawm rau kom tau raws li cov neeg tsim khoom thoob ntiaj teb cov kev xav tau, cov pa oxygen rauv refractory bricks tau ntim rau hauv cov ntoo pallets muaj zog nrog kev tiv thaiv qhwv kom tsis txhob ya raws thiab tawg. Customized packing kuj muaj rau kev xa khoom mus txawv teb chaws, ua kom muaj kev nyab xeeb thiab yooj yim ntawm kev tuav ntawm cov neeg siv khoom.
