GH4169 Bar Txheem Txheej Txheem: Dual Melting ntawm VIM thiab VAR
Theem 1: Nqus Induction Melting (VIM)
Txheej txheem Flow:Cov khoom siv raw yog yaj hauv qhov siab - nqus tsev vacuum.
Lub hom phiaj:Txhawm rau tshem tawm cov pa oxygen, nitrogen, thiab hydrogen. Qhov no tso cai rau qhov sib ntxiv ntawm cov khoom nquag xws li niobium thiab titanium yam tsis muaj kev qhia txog huab cua phem.
Theem 2: Nqus Arc Remelting (VAR)
Txheej txheem Flow:VIM- melted ingot yog siv los ua ib qho electrode rau remelting hauv qab lub tshuab nqus tsev arc.
Lub hom phiaj:Qhov no yog ib kauj ruam tseem ceeb hauv kev daws qhov teeb meem "spotting". Cov txheej txheem tswj kev ua kom muaj zog tshem tawm kev sib cais macroscopic thiab tshem tawm tag nrho cov seem uas tsis yog-hlau inclusions, uas ua rau muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.

FAQ
Q1: Vim li cas VIM + VAR yuav tsum tau ua kom tig turbine qhov chaw?
A: Kev ntxhov siab centrifugal yog qhov hnyav heev. Standard alloys tej zaum yuav muaj microscopic inclusions uas ua rau ib tug rotating ncej los yog disc tawg ntawm siab RPM.VIM+VARyog tus txheej txheem nkaus xwb uas muab kev huv huv metallurgical yuav tsum tau ua kom muaj kev nyab xeeb ntawm kev ya davhlau.
Q2: Puas yog GH4169 hloov pauv nrog Inconel 718 hauv koj cov txheej txheem?
A: Yog lawm.GH4169 yog technische sib npaug rauUNS N07718. Peb txoj kev tsim khoom ua tau raws li txhua qhov kev xav tau thoob ntiaj teb rauAMS 5662, AMS 5596, thiab ASTM B637.
Q3: Koj ua li cas tiv thaiv "Centerline Porosity" nyob rau hauv txoj kab uas hla loj?
A: Peb tswj qhov no los ntawm kev sib xyaw ua ke ntawm kev tswj hwm VAR kev ruaj ntseg thiab kev txo qis qis dua. Los ntawm kev ua kom muaj qhov tsawg kawg nkaus 4: 1 deformation, peb "kho" cov voids sab hauv, kom ntseeg tau 100% cov tub ntxhais ntom ntom.
Q4: Koj puas txhawb nqa thib peb - tog neeg pov thawj thaum lub sijhawm tsim khoom?
A: Yog lawm. Peb zoo siab tos txais kev tshuaj xyuas los ntawmSGS, TUV, los yog BVlos xyuas peb cov txheej txheem melting thiab kuaj ua ntej xa.
