Txheej Txheem Cej Luam Txog Khoom - Kev Sib Tw EAF Slag Pot

An Lub lauj kaub EAF slag(los yoghluav taws xob arc cub tawg slag ladle) tsis yog tsuas yog ib qho me me ntawm lub lauj kaub BOF converter xwb. Nws ua haujlwm nyob rau hauv ib pawg sib txawv kiag li ntawm cov kev ntxhov siab uas ua rau nws yog ib qho ntawm cov castings uas xav tau tshaj plaws hauv lub tshuab hlau.

Cov cub hluav taws xob arc tsim cov slag hauv cov khoom ua ke txhua45–90 feeb– feem ntau yog 12 txog 20 zaug cua sov ib hnub. Txhua lub voj voog muaj xws li:

1. Kev saunrog cov slag molten ntawm 1,600–1,700 ° C (suav nrog cov dej metallic)

2. Tuavthaum lub lauj kaub raug thauj mus hla cov plag tsev tsis sib luag

3. Kev Pov Tsegntawm crane tilt, qee zaum nrog kev cuam tshuam rau ntug qhov slag

4. Cua txiaskom qis dua 300°C ua ntej kev sau tom ntej - tsim kev kub ntxhov heevkev poob siab kub

5. Tsis zoo li cov lauj kaub BOF slag uas feem ntau tau txais ib qho slag ib zaug ua haujlwm, cov lauj kaub EAF tuaj yeem raug rauua kom sov thiab txias sai txog li 20 zaug hauv ib hnubQhov kev hloov pauv kub ntau zaus no ua raukev tawg ntawm kev qaug zog thaum tshav kub- hom kev ua tsis tiav #1 rau EAF slag pots.

Tsis tas li ntawd xwb, cov tshuaj lom neeg ntawm EAF slag sib txawv ntau nyob ntawm qhov zoo ntawm cov khoom seem, kev ntxiv cov hlau sib xyaw, thiab kev xyaum ua kom zoo. Slag tuaj yeem yog ** yooj yim heev ** (CaO siab, nplaum) lossiskua qaub(SiO₂ siab, kua). Txhua tus xav tau cov qauv sab hauv thiab cov khoom teb sib txawv.

Womic Steel tau tsimCov lauj kaub slag uas tau kho kom zoo dua los ntawm EAFuas hais txog peb qhov teeb meem tshwj xeeb:

●Kev tawg ntawm kev qaug zog ntawm lub cev- daws tau los ntawm cov hlau zoo-grain + tswj kev kho cua sov txias

●Slag khov-on- daws tau los ntawm patented ob chav-slope sab hauv contour thiab anti-stick txheej

●Kev puas tsuaj ntawm kev pov tseg- daws tau los ntawm lub npoo uas muaj zog thiab cov duab uas nqus tau qhov cuam tshuam

EAF Slag Pot Hluav Taws Xob Arc Rauv Slag Tshwj Xeeb Rau Kev Ua Hlau Muaj Zog Siab - Womic Steel

Vim li cas ho xaiv Womic Steel rau koj lub lauj kaub EAF Slag?

Feature Qhov Zoo Tshaj Plaws ntawm EAF
Nb-V Microalloyed Hlau Muaj cov niobium thiab vanadium me me uas ua rau cov hlau tawg qeeb zuj zus. Ua pov thawj tias nws ua rau cov hlau tsis ua haujlwm ntau dua 70% piv rau cov hlau cam khwb cia.
Ua kom nrawm dua + Tempered Tom qab austenitizing, cua yuam (tsis yog cua tseem) tsim cov qauv pearlite + bainite zoo dua - tiv taus kev poob siab thermal ntau dua.
Lub tais sab hauv ob chav Nce toj sab saud 12°, nqes hav sab qis 8°, nrog rau thaj chaw tiaj tiaj 150mm ntawm qhov chaw cuam tshuam. Lub sijhawm tso tawm slag txo qis 40% hauv kev sim teb.

Kev Tswj Xyuas Zoo ntawm EAF Slag Pot - Kev Txheeb Xyuas Kev Siv Thermal Cycling

Dhau li ntawm tus qauv NDT, peb uakev sim tshuaj xyuas lub voj voog kub puas tsuajntawm cov qauv thawj zaug. Daim coupon kuaj me dua (kev kho cua sov tib yam) raug rau cov voj voog cua sov sai dua hauv peb lub cub tawg hauv chav kuaj. Cov kab nrib pleb raug ntsuas los ntawm cov xim nkag mus txhua 500 voj voog. Qhov kev xeem raug xaus thaum qhov ntev ntawm qhov tawg tshaj 3 hli. Tus lej ntawm cov voj voog ua tiav tau sau tseg thiab lav kom ua tau raws li koj qhov yuav tsum tau ua tsawg kawg nkaus (feem ntau 2,500 voj voog).

Cov kev kuaj xyuas ntxiv rau EAF:

Kev kos duab ultrasonic tuab ntawm phab ntsa- peb tsim ib daim ntawv qhia tuab uas muaj xim sib txawv ntawm tag nrho lub lauj kaub, qhia txog txhua qhov chaw uas tsis tshua muaj npe.

Kev tshuaj xyuas lub vojvoog ntawm cov hauv paus Trunnion– siv lub ntsuas qhov sib txawv, peb xyuas kom meej tias lub vojvoog = 50mm min.

Qhov ncaj ntawm lub log- tom qab kev kho cua sov, peb ntsuas qhov tiaj tiaj ntawm lub npoo; qhov sib txawv ≤5mm ua kom ntseeg tau tias haum nrog lub qhov rooj slag.

Cov Lus Nug Feem Ntau (FAQ) - EAF Tshwj Xeeb

Q: Kuv yuav paub li cas yog tias kuv lub EAF xav tau lub lauj kaub slag tshwj xeeb?
A: Yog tias koj khiav ntau tshaj 10 qhov kub hauv ib hnub lossis ntsib kev tawg hauv 12 lub hlis ntawm cov lauj kaub txheem, koj xav tau EAF-optimized tsim. Tsis tas li ntawd, yog tias koj pom slag lo ntau dhau lossis xav tau kev tsoo tes, peb cov ntaub ntawv tiv thaiv kev lo yuav pab tau.

Q: Kuv puas siv tau tib lub lauj kaub slag rau BOF thiab EAF?
A: Tsis pom zoo - cov lauj kaub EAF yog tsim los rau kev caij tsheb kauj vab sai dua, phab ntsa nyias dua, thiab cov yam ntxwv sib txawv ntawm kev sib txuas slag. Kev siv cov lauj kaub BOF hauv EAF ua rau tawg ua ntej lub sijhawm; kev siv cov lauj kaub EAF hauv BOF yuav ua rau lawv kub dhau. Ib txwm siv cov lauj kaub tshwj xeeb.

Q: Koj puas muaj kev pab nyiaj txiag lossis kev pauv pauv lauj kaub?
A: Yog - peb muaj lub lauj kaub slag ua tus qauv kev pabcuam: koj them rau ib tuj ntawm cov hlau tsim tawm, thiab peb muaj thiab tswj hwm cov lauj kaub. Kev cog lus tsawg kawg yog 5 xyoos. Nug kom paub meej ntxiv.

Q: Lub neej ua haujlwm ntawm cov txheej txheem tiv thaiv lo yog dab tsi?
A: Raws li kev ua haujlwm EAF ib txwm muaj (cov slag yooj yim, 15 lub voj voog/hnub), lub txheej txheej kav ntev li 9-12 lub hlis. Kev rov txheej txheej tuaj yeem ua tiav hauv koj lub Hoobkas los ntawm peb cov kws tshaj lij (lossis peb muab cov khoom siv txheej txheej). Tus nqi hloov txheej txheej yog ~ 15% ntawm tus nqi lauj kaub tshiab.

Q: Koj yuav ua li cas thiaj hloov tau qhov chaw thaum muaj xwm txheej ceev yog tias lub lauj kaub tsis ua haujlwm tam sim ntawd?
A: Peb khaws cov khoom me me (2-4 lub lauj kaub) ntawm cov EAF loj hauv peb lub tsev rau khoom. Rau cov neeg siv khoom uas muaj daim ntawv cog lus pabcuam, peb xa khoom los ntawm huab cua hauv 72 teev.

Q: Koj puas tuaj yeem ntxiv cov sensors kub rau hauv lub lauj kaub?
A: Yog - peb tuaj yeem teeb tsa cov hnab tshos thermocouple (txog li 4 qhov chaw) nrog Inconel sheathing. Cov sensors tuaj yeem txuas nrog lub monitor portable lossis koom ua ke nrog koj lub Hoobkas DCS.

Q: Qhov yuav tsum tau ua kom tiav qhov chaw rau EAF slag adhesion yog dab tsi?
A: Lub tais sab hauv yuav tsum tau ua kom Ra ≤ 6.3 μm. Cov nplaim As-cast txhawb kev nplaum. Peb qhov kev tsim ob chav-slope ua ke nrog kev ua haujlwm zoo txo ​​​​​​kev nplaum ntau heev.
