Batchency sib xws piav qhia los ntawm cov khoom nyoos los ua tiav cov khoom lag luam
Tso lus
C103 niobium hafnium alloy(feem ntau raug xa mus rau raws li nb - 10hf {{4 4}} 1ti) yog pob zeb hluav taws xob "nyob rau hauv lub pob zeb hluav taws xob" nyob rau hauv lub pob zeb hluav taws xob "nyob rau hauv cov pob zeb hluav taws xob" hauv pob zeb lub cav ntoo siab thawb cov tsev thiab cov khoom siv. Nws qhov zoo tshaj plaws siab kub, creep tsis kam, thiab weldability yog zoo nyob ntawm precise tshuaj muaj pes tsawg leeg thiab ruaj khov Micrtructure. Yog li ntawd, kom ntseeg tau tias cov tshuaj lom neeg muaj pes tsawg leeg thiab cov neeg kho tshuab ntawm txhua pob Qab qhov no yog ib txoj kev tswj hwm zoo heev uas sau los ntawm tag nrho cov txheej txheem ntawm tag nrho cov txheej txheem ntawm melting, kev kho, kho cua sov, thiab kuaj cua sov, thiab kuaj cua sov, thiab kuaj cua sov, thiab kuaj cua sov, thiab kuaj cua sov, thiab kev soj ntsuam.
Cov kev coj dawb huv thiab kev sib txawv ntawm cov khoom siv raw yog thawj qhov ua ntej rau batch muaj peev xwm, thiab ib qho "kev tswj peb npaug" yuav tsum tau siv:
1. Qauv ntawm Raw cov ntaub ntawv xaiv: Cov ntaub ntawv raw yog ntau dua lossis sib npaug ntawm ntau dua lossis muaj sib npaug ntawm 99.9%, thiab cov ntawv elalolytic. Cov roj tsis txaus ntseeg (C tsawg dua lossis muaj sib npaug rau 0.03%, o tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug nrog 0.005%) yog txwv nruj me ntsis. Ua tag nrho cov khoom siv tau pom ntawm txhua lub batch ntawm cov khoom siv raw los ntawm icp {} ms spectroscopic tsom xam, thiab tsuas yog coj cov khoom nyoos uas tau raws li Ams 7912 tus qauv.
2. Kev ua kom zoo ntawm cov txheej txheem Batching: Siv "Intermediate Alloy Prefabrication), thiab ib co niobium ua ntej los ntawm kev sib xyaw ua ntej tshaj plaws (HFT Nws sib xyaw. Tswj lub nrawm ntawm 30r / min rau 4 teev, thiab siv lub tshuab ziab khaub ncaws kom qhuav (12h) kom tshem tawm adsorbed noo noo.
3. Tus neeg xa khoom sib koom ua ke tswj hwm: Ua rau Ext9100 system cov ntawv ceeb toom (MTC) thiab cov txheej txheem muaj peev xwm muab cov ntaub ntawv khoom siv (CPK ntau dua lossis sib npaug ntawm cov khoom siv raw. Tsim kom muaj tus xa khoom ua tiav kev ua tiav cov qhab nia uas txuas txuas ntxiv Batch cov nqi tsim nyog los txiav txim.
Melting yog kauj ruam tseem ceeb hauv kev tswj hwm kev sib xws ntawm cov Cheebtsam, siv lub sijhawm "lub sijhawm ua haujlwm me me tau melting + parameter kaw {} lub vojv tswj" thev naus laus zis:
1. Khoom siv thiab ib puag ncig tswj: ib qho hluav taws xob tswj: Ib puag ncig kev txaj me me melting rauv (Ebchr) tau xaiv, thiab peb lub tshuab nqus tsev sib hloov argon hloov ua ntej melting. Lub nqus tsev nqus zaum kawg yog tsawg dua lossis sib npaug rau 5 ⁻⁴ 10 ⁻⁴ 10 ⁻⁴ 10 ⁻⁴ ⁻⁴, thiab sib npaug nrog 99.999% (dew point tsawg dua lossis sib npaug} 70}). Crucible yog ua los ntawm high-ceev graphite cov khoom siv thiab undergoes decarburization kev kho mob thaum 1950℃ua ntej siv kom tsis txhob muaj kuab paug carburizing.
2. Kev tswj hwm ntawm melting me me: tau txais qhov "peb- barron Pib lub zog ntawm 30kW, preheating rau 20 feeb); ② Melting theem (hluav taws xob 80-100kw, ruaj khov txiv ntseej pas dej kub ntawm 2200 ± 50 degree); ③ Rov ua theem (lub zog txo mus rau 50kw, rwb thaiv tsev rau 15 feeb los txhawb kev sib txawv). Ua 3 txoj kev sib law liag melting txheej txheem, thiab tom qab txhua tus txheej txheem, qauv thiab sim cov kev sib txawv ntawm hafnium thiab titanium ntsiab yog tsawg dua lossis sib npaug rau ± 0.2%.
3. Cov thev naus laus zis rau deoxidation thiab Decarbonancy: los ntawm kev kho cov De / C) thiab cov carbides yeem tuaj yeem ua tiav ntawm Sinining Kub ntawm 1950 ± 50 degree. Tom qab melting, lub ingting yog txias nyob rau hauv lub cub hluav taws (txias tus nqi 5℃/ min) kom zam dhau lub teeb segregation los ntawm kev txias sai.
Los ntawm kev ua qauv txheej txheem tsis sib xws thiab kev soj ntsuam online, xyuas kom meej cov khoom siv neeg kho tshuab:
1. Cov txheej txheem kub ua hluav taws xob: kev tshuaj ntsuam xyuas kom nruj ntawm xyoo 750-875, kom ntseeg tau tias muaj ntau dua lossis sib npaug ntawm cov qoob loo loj (nruab nrab qoob loo loj (nruab nrab qoob loo loj me me ntawm 5-7 qib). Thaum lub sijhawm ua, tus pas ntsuas kub infrared siv los saib xyuas qhov kub ntawm lub billet hauv lub sijhawm tiag tiag. Yog tias qhov sib txawv tshaj plaws ± 20 degree, lub tshuab yuav nres tam sim ntawd rau kev hloov kho.
2. Kev tswj kev kub kub: Siv cov qauv ua kom muaj kev kho cua sov raws li cov khoom siv HBS35-45 thiab elongation ntau dua lossis sib npaug rau 35%; ② Lub xeev nyuaj (y State): Los ntawm kev txias rolling deformation thiab tsawg kev kub siab, lub hardness hbsealing, lub hardness lub zog ntau dua los yog sib npaug zos rau 650mpa tswj hwm. Kev kho cua sov yog nqa tawm hauv lub tshuab nqus dej kom tsis txhob muaj qhov sib dhos saum npoo oxidation cuam tshuam rau qhov tseeb ntawm kev sim tshuaj ntsuam.
3. Cov Txheej Txheem Saib Xyuas Kev Tswj Xyuas: Siv Spc cov txheej txheem tswj cov txheej txheem xws li kev kub ntxhov, thiab ua kom muaj kev kho cua sov, thiab ua kom cov lus ceeb toom ua cua sov, thiab ua kom cov lus ceeb toom thaum tshav kub kub<1.33.
Tsim kom muaj "kev soj ntsuam tag nrho
1. Cov khoom siv txuas ntxiv rau qhov ncauj lus:
- Kev Kuaj Xyuas Kev Kuaj: Peb qhov qauv los ntawm ntau qhov chaw ntawm txhua pob yog noj thiab sim siv cov tshuaj tua kab kom ntseeg tau tias yog cov tshuaj lom neeg ua tau raws li ASTM B393 cov qauv;
- Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Chav Kawm Kub / Kub (1000 degrees)
- Kev sim sab hauv: Ultrasonic kev sim (UT) thiab TradorGraphic Xeem (RT) yog siv, thiab tsis muaj qhov hws nrog ntau dua lossis sib npaug nrog 0.5 hli.
2. Cov digital traceazebility cov lis dej num: Muab cov ntaub ntawv tshwj xeeb uas muaj cov ntaub ntawv raw, tso tawm 18 plicing (cov ntaub ntawv ua haujlwm, thiab cov ntaub ntawv ntsuas. Los ntawm cov mes system, tag nrho cov saw ntawm "cov khoom siv rawing ua cov khoom tiav" tuaj yeem raug nyob hauv 4 teev nyob rau hauv cov ntaub ntawv ntawm ib qho txawv txav.
Kev lav
1. Kev tswj hwm kev tswj hwm zoo: Ua haujlwm ntawm ISO 9001 thiab AS9100 ob lub systems, qhia meej cov qauv kev ua haujlwm thiab cov neeg muaj lub luag haujlwm rau txhua qhov txuas. Tsis tu ncua coj mus kuaj hauv sab hauv thiab cov txheej txheem tshuaj xyuas (VDA 6.3 tus qauv) los txheeb xyuas qhov tsis muaj zog.
2. Nraj txhim kho mechanism: Customation Peb lub hlis twg txheeb xyuas cov ntaub ntawv thiab ua 8D hauv paus kev tsom xam rau cov kab ke nrog kev ua tau zoo dua 5%. Piv txwv li, los ntawm kev ua kom zoo melting thiab rwb thaiv tsev sijhawm ntawm Hafnium Bas tuaj yeem raug txo los ntawm ± 0.3% rau ± 0.15%.
Lub Batch sib txig lav ntawm C103 Alloy yog ib qho kev tsim tawm ntawm "cov khoom siv raw, kev tswj xyuas cov txheej txheem zoo, thiab kho kom zoo nkauj". Los ntawm prefabrication ntawm NB HF Intermediate alloy rau qhov ntsuas hluav taws xob melting, los ntawm kev tswj hwm kub ntawm lub hauv paus nruab nrab hauv qhov siab- kawg teb. Qhov kev tswj hwm no tseem muab cov kev siv ua haujlwm vemadigm rau kev ua kom muaj kev sib xws hauv lwm qhov siab - kub alloys.
