Tsawg Gas Ntsiab Cai Hlau Billet
Ultra-Oxygen Tsawg & Nitrogen|High Purity rau Nqus Melting & Precision Casting
Product Overview
Gas impurities (oxygen, nitrogen, hydrogen) yog cov yeeb ncuab tsis pom hauv cov hlau ua haujlwm siab thiab castings. Lawv ua rau:
Porosity & pinholes- ua rau tsis lees txais castings
Oxide suav nrog- txo qaug zog lub neej
Hydrogen embrittlement- kev pheej hmoo ntawm kev tawg
Pebtsawg roj cov ntsiab lus hlau billetyog engineered los kov yeej cov kev cov nyom no. Los ntawm kev tswj electrolytic refining ua raws linqus tsev degassingthiabinert cua kub dov, peb ua tiav qhov tshwj xeeb qis ntawm O, N, thiab H. Qhov tshwm sim yog qhov huv, ntom hlau hlau uas ua tau zoo hauv lub tshuab nqus tsev melting, precision casting, thiab tshwj xeeb alloy ntau lawm.
Raws li covtus tsim tawm tiag, peb muabHoobkas- tus nqi ncaj qhathiab tag nrho traceability, nrog rau cov ntawv pov thawj roj (O, N, H los ntawm inert gas fusion). Kev cai qhov ntau thiab tsawg thiab tshuaj muaj pes tsawg leeg muaj nyob rau ntawm kev thov.

Gas Control - Qhov txawv ntawm qhov zais
Cov khoom siv hlau feem ntau tsuas yog tsom rau cov chemistry (C, Si, Mn, P, S). Tab sis rau cov kev siv tseem ceeb,roj cov ntsiab lus tseem ceeb sib npaug. Peb cov qib roj gas:
| Gas Element | Yam khoom (ppm) | Guaranteed Max (ppm) |
|---|---|---|
| Cov pa oxygen (O) | 30 ppm | 50ppm (0.005%) |
| Nitrogen (N) | 20 ppm | 40 ppm (0.004%) |
| Hydrogen (H) | 1.5 ppm ib | 3 ppm (0.0003%) |
Cov qib roj tsawg no ncaj qha txhais rau qhov tsis lees paub tsawg dua, lub neej ntev dua, thiab cov txiaj ntsig siab dua hauv koj cov txheej txheem melting lossis casting.
Tsim los rau Nqus Melting & Precision Casting
Vacuum induction melting (VIM):Peb lub pob zeb muaj cov pa roj tsawg tsawg, txo cov pa tawm thiab txaws thaum VIM.
Kev nqis peev casting:Cov pa oxygen tsawg txhais tau tias tsawg dua cov yeeb yaj kiab oxide thiab suav nrog hauv cov phab ntsa nyias nyias.
Superalloy ntau lawm:Lub hauv paus hlau huv huv tiv thaiv qhov tsis xws luag hauv cov nickel-hlau superalloys.
Factory Direct - Zoo tiag tiag, Tus nqi tiag
Peb ua haujlwm peb tus kheej electrolytic hlau cog thiab lub tshuab nqus tsev degassing. Koj zam kev lag luam markups (txuag 15-25%) thiab tau txais:
Kev nkag ncaj qha rau peb cov ntaub ntawv tshuaj ntsuam roj rau txhua qhov cua sov
Lub sij hawm luv luv - 10-15 hnub rau cov qauv loj
Customized gas specifications muaj (piv txwv li, O Tsawg dua lossis sib npaug li 30 ppm thaum thov)
Daim ntawv thov
| Kev lag luam | Siv Case | Vim li cas Low Gas Matters |
|---|---|---|
| Aerospace superalloys | Base hlau rau Ni-Fe alloys (Invar, Kovar) | Tiv thaiv roj porosity thiab embrittlement |
| Precision peev casting | Ntxuav hlau qhov chaw rau nyias-wall castings | Txo oxide inclusions thiab defects nto |
| Vacuum induction melting (VIM) | Them cov khoom siv rau cov hlau tshwj xeeb | Minimizes outgassing thiab alloy muaj pes tsawg leeg drift |
| Cov khoom siv kho mob alloys | High-purity hlau rau implantable devices | Tshem tawm cov tshuaj lom thiab ua tsis tiav gas |
| Nuclear Cheebtsam | Tsawg-hydrogen hlau rau reactor qhov chaw | Hydrogen-induced cracking yog tsis tsim nyog |
Cov lus nug nquag
Q: Vim li cas cov pa roj tsawg tseem ceeb hauv cov hlau billet?
A: Oxygen tsim cov oxide suav nrog uas txo qis lub neej qaug zog. Nitrogen tuaj yeem ua rau nitride embrittlement. Hydrogen ua rau tawg (hydrogen embrittlement) thiab porosity. Rau lub tshuab nqus tsev melting lossis precision casting, cov ntsiab lus roj tsawg yog qhov tseem ceeb rau cov txiaj ntsig tsis raug.
Q: Koj kuaj cov ntsiab lus roj li cas?
A: Peb siv inert gas fusion (IGF) analyzers (LECO) ib ASTM E1019 rau O thiab N, thiab ASTM E1447 rau H. Txhua qhov cua sov yog kuaj los ntawm cov tub ntxhais billet tom qab kub dov. Cov txiaj ntsig tau suav nrog hauv peb Daim Ntawv Pov Thawj Kev Ntsuam Xyuas.
Q: Koj puas tuaj yeem ua tiav cov pa oxygen tsawg dua, piv txwv li, Tsawg dua lossis sib npaug li 30 ppm?
A: Yog. Rau cov ntawv thov uas xav tau cov pa oxygen tsawg dua lossis sib npaug li 30 ppm (0.003%), peb muab qib hwm. Thov hu rau peb nrog koj lub hom phiaj tshwj xeeb - kev ua haujlwm ntxiv tuaj yeem ncua sij hawm ua ntej 5-7 hnub.
Q: Puas yog lub tshuab nqus tsev no haum rau lub tshuab nqus tsev induction melting (VIM) yam tsis muaj pre-melting degassing?
A: Yog. Peb cov khoom siv roj tsawg yog tsim tshwj xeeb rau VIM pub. Koj tuaj yeem them ncaj qha yam tsis muaj degassing ua ntej, txo lub sijhawm voj voog thiab txhim kho yaj zoo.
Q: Qhov ntau thiab tsawg yog muaj?
A: Txheem square billets: 60 × 60 mm, 80 × 80 mm, 100 × 100 mm, 150 × 150 mm. Rectangular thiab round billets muaj. Ntev ntawm 500 mm mus rau 6 meters. Custom size txais tos.
Q: Koj tus MOQ yog dab tsi rau cov khoom siv roj tsawg?
A: MOQ yog 3 tons rau qhov ntau thiab tsawg. Kev txiav txim mus sib hais (500-1000 kg) muaj rau kev soj ntsuam - thov nug.
