Txheej Txheem Cej Luam Khoom - Cov Kev Xav Tau Tshwj Xeeb ntawm LF / VD Slag Pots

A LF slag lauj kaub(lub thawv ntim cov slag ntawm lub cub tawg) los yogVD slag lauj kaub(lub thoob nqus tsev degassing slag) cov tes tuavcov khoom siv hluavtaws- tsis yog cov slag kub heev los ntawm EAF lossis BOF, tab sis yog cov khoom sib xyaw ua ke ntawm cov txiv qaub ntsuab, fluorspar, thiab cov hlau sib xyaw uas tsim los ua kom cov hlau yaj zoo.

Dab tsi ua rau cov lauj kaub LF / VD sib txawv?

1. Qhov kub ntawm cov slag qis dua (~ 1,500 ° C piv rau 1,650 ° C rau EAF), tab sis lub sijhawm tuav ntev dua– qee zaum 60–90 feeb ib zaug cua sov. Lub lauj kaub yuav tsum tiv tauskev hloov pauv ntawm cov kab mob creepntawm qhov kub thiab txias tas mus li.

2. Cov slag hluavtaws yog cov kua heev thaum yaj tab sis nws nplaum heev thaum nws txias.Cov cheeb tsam tuag lossis cov ces kaum sab hauv ntse ua rau muaj slag uas txo qis lub peev xwm dhau sijhawm.

3. Lub tshuab nqus tsev degassing (VD) ua rau muaj qhov yuav tsum tau tshwj xeeb: lub lauj kaub slag yuav raug muab tso rau hauv lub tshuab nqus tsev (0.5–1 torr) rau lub sijhawm luv luv. Txhua qhov microporosity hauv qhov casting tuaj yeem tawm cov pa, ua raukev tsim cov npuas hauv cov hlaulos yog - phem dua -kev tawg ntawm lub lauj kaubyog tias muaj qhov loj loj.

4. Cov lauj kaub LF/VD feem ntau raug tswj los ntawm tib lub ladle turret uas tsa lub ladle hlau.Qhov no txhais tau tias lub lauj kaub yuav tsum sib dua thiab me dua li cov lauj kaub EAF/BOF kom haum rau hauv qhov sib nrug ntawm caj npab turret thiab qhov geometry ntawm tus nuv crane.

5. Cov tshuaj lom neeg ntawm cov slag yog qhov yooj yim (siab CaO / Al₂O₃), uas tawm tsam cov ciam teb ntawm silicon thiab txhuas.Kev saib xyuas tshwj xeeb rau cov khoom uas tsis yog hlau yog qhov tsim nyog.

Womic Steel lub LF/VD slag pots tau tsim los nrogcov ntsiab lus hydrogen tsawg heev, cov duab sab hauv du, thiabprecision compact qhov ntev- raws nraim li qhov metallurgy theem nrab xav tau.

Cov Lus Nug Feem Ntau (FAQ) - Tshwj Xeeb Rau LF/VD

Q: Vim li cas cov ntsiab lus hydrogen thiaj li tseem ceeb rau cov lauj kaub slag?
A: Thaum lub sijhawm nqus tsev degassing, cov hydrogen uas yaj hauv cov hlau casting tuaj yeem diffuse thiab recombine rau hauv molecular hydrogen ntawm cov khoom tsis yog hlau. Qhov no tsim kev siab sab hauv, ua rau blistering lossis tawg - qee zaum hu ua "hydrogen flaking." LF/VD pots yog qhov yooj yim vim tias lawv raug tuav hauv qab nqus tsev rau lub sijhawm ntev.

Q: Koj puas tuaj yeem lees paub cov ntsiab lus hydrogen kom tsawg dua 1.0 ppm?
A: Yog, tab sis yuav tsum tau muaj kev xyaum tshwj xeeb rau kev yaj (kev yaj los ntawm lub tshuab nqus tsev lossis kev yaj electroslag) thiab kim dua. Rau feem ntau ntawm cov ntawv thov, 1.5 ppm txaus.

Q: Koj puas muab kev kuaj xyuas qhov xau ntawm lub tshuab nqus tsev?
A: Yog, peb ua qhov kev sim helium xau raws li qhov kev thov thiab muab daim ntawv pov thawj raws li ISO 20485. Peb lav qhov xau <1 × 10⁻⁶ mbar·l/s.

Q: Yuav tsum hloov cov lauj kaub LF slag ntau npaum li cas?
A: Feem ntau txhua 3-5 xyoos, nyob ntawm seb lub voj voog hloov pauv li cas. Kev hloov pauv ntawm lub cev yog qhov tseem ceeb uas ua rau lub neej tsis muaj zog. Kev tshuaj xyuas UT txhua xyoo tuaj yeem pom cov qhov khoob thaum ntxov.

Q: Koj puas tuaj yeem muab cov lauj kaub slag nrog lub tsho cua txias?
A: Rau cov ntawv thov LF uas xav tau kev txias sai ua ntej siv tom ntej, peb tuaj yeem tsim lub tsho tiv cua (lub plhaub sab nraud hlau nrog cov channel cua). Qhov no txo ​​lub sijhawm txias los ntawm 90 feeb mus rau 20 feeb.

Q: Koj cov LF slag pots puas sib xws nrog cov tshuab nrhiav qib slag tsis siv neeg?
A: Yog. Peb muab ib lub mounting pad tiaj tiaj rau ntawm lub rim rau lub radar lossis laser sensor. Xwb, peb tuaj yeem embed thermocouples rau slag txheej nrhiav.

Q: Koj puas muaj kev cob qhia rau kev tshuaj xyuas lub lauj kaub LF?
A: Yog, peb muab kev cob qhia ib hnub rau koj pab neeg saib xyuas: UT ntawm trunnions, cov qauv tshuaj xyuas pom, thiab cov txheej txheem kho qhov tawg.

Q: Lub warranty ib txwm rau lub lauj kaub LF / VD slag yog dab tsi?
A: 24 lub hlis lossis 10,000 lub voj voog - qhov twg los ua ntej. Rau kev pabcuam nqus tsev (nrog kev kuaj xyuas qhov xau), kev lees paub raug ncua mus txog 36 lub hlis tiv thaiv kev tawg hydrogen.
