Koj puas tau xav tias yog vim li cas ob lub GH3030 (nickel{1}}raws li 75) cov kav hlau steel nrog cov ntaub ntawv qhia txog tshuaj muaj pes tsawg leeg tuaj yeem muaj kev ua neej sib txawv, ib qho kav ntev li 3000 teev thaum lwm qhov ua tsis tiav tom qab tsuas yog 500 teev?
Cov lus teb yog nyob rau hauv "pob ntseg" purity ntawm yaj. Rau cov ntawv thov tseem ceeb xws li siab - kub thiab siab - cov tshuab ua haujlwm siab, qhov kev sib tw loj tshaj plaws yog cov khoom siv sab hauv tsis zoo- cov khoom me me thiab cov pa roj ua haujlwm zoo li lub sijhawm tawg. Raws li ib tug neeg muab khoom ntawm high-zoo siab- kub alloys, Gnee Steel muab GH3030 steel kav refined siv VIM + ESR txheej txheem, tsim los xyuas kom meej xoom- tsis xws luag txawm nyob rau hauv lub ntiaj teb no xav tau kev pab ntau tshaj.

Qhov cuam tshuam ntawm VIM + ESR Refining ntawm GH3030 Steel Pipes ntawm Standard Melting
Piv rau cov txheej txheem melting txheem (xws li lub tshuab nqus tsev induction melting los yog cua induction melting ib leeg), refining GH3030 steel kav siv lub tshuab nqus tsev induction melting + electroslag remelting (VIM + ESR) txheej txheem ho txhim kho nws purity, uniformity, thiab siab -kub kev ua tau zoo. Qhov txheej txheem melting dual no txo qhov suav nrog, leej faj, thiab roj cov ntsiab lus, yog li muab cov khoom siv huv thiab zoo dua microstructure rau cov ntawv thov tseem ceeb.
Dab tsi yog electroslag remelting (ESR)?
Electroslag remelting (ESR) yog txheej txheem refining uas siv molten slag los yaj hlau thiab tshem tawm impurities, xws li oxygen, los ntawm cov hlau. Cov txheej txheem no feem ntau yog ua los ntawm kev tswj hwm huab cua los txhim kho deoxidation thiab txhim kho cov khoom zoo.
1.Qhov cuam tshuam ntawm VIM + ESR txheej txheem ntawm GH3030 steel:
Txhim kho purity thiab inclusion cov ntsiab lus: Cov txheej txheem ESR txo qhov loj tshaj plaws thiab tag nrho cov uas tsis yog-hlau inclusions, feem ntau tshem tawm inclusions loj dua 10-12 μm. Qhov no yog qhov zoo tshaj rau tus qauv induction melting, uas tuaj yeem ua rau ntau dua oxide / sulfide cov ntsiab lus.
Chemical composition tswj:Cov txheej txheem VIM tso cai rau kev tswj hwm cov ntsiab lus nquag (Al, Ti) hauv npib tsib xee-raws li alloys, thaum cov tshuaj tiv thaiv slag hauv cov txheej txheem ESR zoo txo cov ntsiab lus sulfur (feem ntau yog 5-75%).
Fineer microstructure:Cov txheej txheem ceev thiab tswj kev ruaj khov hauv ESR ua rau muaj qhov zoo dua, cov qauv zoo dua qub, txo kev sib cais thiab txhim kho cov yeeb nkab machinability.
Txhim kho siab -kev ua haujlwm kub:GH3030 steel kav uas tsim los siv VIM + ESR txheej txheem nthuav tawm ntau dua tawg lub zog, zoo siab -kub creep kev ua tau zoo, thiab superior oxidation tsis kam, ua tsaug rau lawv ntau dua microstructure uniformity.

2. Tus Txheej Txheem Duel: VIM+ESR vs. Standard Melting
Nkag siab txog cov txheej txheem melting yog qhov tseem ceeb rau kev ua kom paub meejAdvanced Manufacturingkev txiav txim yuav khoom.
Txheem Melting (EAF / AOD)
Kev lag luam feem ntau -qib GH3030 yog tsim los ntawm Electric Arc Rauv (EAF) lossis Argon Oxygen Decarburization (AOD).
Qhov teeb meem:Cov khoom no raug rau cov huab cua, ua rau cov qib siab dua ntawm cov pa oxygen (O₂), Nitrogen (N₂), thiab Hydrogen (H₂).
Qhov tshwm sim:Coarse grain qauv, non{0}}metallic inclusions (oxides/sulfides), thiab "kub shortness" thaum lub sij hawm vuam los yog fabrication.

3.Our VIM + ESR Dual Refining
Peb siv ob -theem siab- txheej txheem purity los xyuas kom meejHwm Zoo:
VIM (Nqus Induction Melting):Cov khoom nyoos yog yaj hauv lub tshuab nqus tsev sib sib zog nqus. Qhov no boils tawm volatile impurities thiab tiv thaiv ib tug gas pickup, kom ntseeg tau lub meej meej tshuaj muaj pes tsawg leeg.
ESR (Electroslag Remelting):Lub ingot yog remelted los ntawm ib tug tshuaj active slag. This acts as a "molecular filter," removing final inclusions and creating a dense, uniform grain structure with zero segregation.
