1 Khoom Description
Vim nws cov corrosion kuj zoo heev, titanium yog dav siv los ua cov khoom siv rau ntau yam tshuaj lom neeg cov hlab ntsha thiab cov khoom siv hluav taws xob, tab sis qhov tsis zoo yog tias tus nqi siab, thiab kev siv cov titanium composite daim hlau tuaj yeem daws qhov teeb meem no. Titanium clad phaj yog ib hom tshiab ntawm bimetallic high-efficient zog-txuag khoom, uas yog ua los ntawm titanium raws li cov cladding, carbon steel los yog tsis tshua muaj hlau alloy steel raws li lub hauv paus txheej, los ntawm explosive bonding los yog dov thiab crimping. Lub titanium clad steel phaj rau siab muaj lub zog siab thiab corrosion kuj ntawm coated titanium hlau tsis tau tsuas yog txuag tau ntau cov ntaub ntawv titanium, tab sis kuj muaj cov khoom uas ib leeg tsis muaj. Yog li ntawd, piv nrog cov ntshiab titanium, cov khoom siv chim, raj phaj thiab lub taub hau ua los ntawm titanium clad steel phaj rau siab tsis tau tsuas yog xyuas kom meej qhov kev ua tau zoo, tab sis kuj ho txo qhov project nqi.
2 Kev soj ntsuam nyuaj ntawm titanium composite phaj
Qhov nyuaj ntawm titanium clad phaj vuam yog kev kho cov txheej txheem hloov ntawm titanium thiab hlau. Yog tias fusion vuam tau txais ncaj qha, nkig intermetallic tebchaw xws li FeTi thiab Fe2Ti yuav raug tsim nyob rau hauv fusion zone. Cov sib xyaw ua ke ntawm intermetallic thiab eutectic nrog qis melting point yuav ua kom lub zog ntawm cov khoom, txo cov plasticity ntawm cov khoom, thiab cuam tshuam ncaj qha rau cov khoom siv ntawm cov khoom sib txuas. Tsis tas li ntawd, vim qhov sib txawv loj ntawm cov khoom siv thermophysical ntawm titanium thiab hlau, qhov shrinkage ntawm cov vuam tsis sib xws thaum lub sij hawm txias, ua rau cov vuam loj hauv kev ntxhov siab, thiab tseem ua rau cov vuam tawg hauv qhov xwm txheej loj. Yog li ntawd, nws yuav luag tsis yooj yim sua kom tsim ib qho txuas txuas txuas ntxiv ntawm titanium thiab hlau ncaj qha los ntawm fusion vuam.
3Kev cuam tshuam ntawm cov roj ntws thiab lub taub hau loj ntawm kev tiv thaiv
Thaum vuam titanium txheej, phau ntawv TIG vuam yuav tsum tau. Piv nrog stainless hlau, titanium txheej muaj cov thermal conductivity tsis zoo thiab loj weld pas dej ua ke txoj kab uas hla. Yog li ntawd, siv tib lub nozzle li vuam stainless hlau tsis tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws. Vim li no, nozzles nrog ntau qhov sib txawv ntawm 5 #, 7 #, 9 # thiab 15 # tau siv raws li. Raws li tib yam li lwm yam kev mob, sim seb puas hloov cov roj tiv thaiv ntau yam cuam tshuam rau qhov vuam zoo.
4 Vuam txoj kev thiab cov cuab yeej siv
Vim tias lub hauv paus txheej yog carbon steel los yog cov hlau tsis tshua muaj hlau, nws cov txheej txheem vuam yog cov paub tab hauv Suav teb. Cov txheej txheem vuam feem ntau yog electrode arc vuam thiab CO2 roj shielded vuam. Cov electrode arc vuam siv nyob rau hauv qhov kev xeem no. Rau cov titanium txheej, vim nws cov tshuaj lom neeg muaj zog, vuam txoj kev xws li electrode arc vuam thiab CO2 roj shielded vuam tsis tuaj yeem siv rau vuam. Tam sim no, feem ntau siv vuam txoj kev yog argon tungsten arc vuam, submerged arc vuam thiab nqus electron beam vuam. Xav txog qhov ua tau zoo, vuam nqi thiab qhov chaw tsim kho ib puag ncig, feem ntau siv argon tungsten arc vuam txoj kev raug xaiv thaum kawg.
5 Base hlau Base hlau khoom
Cov txheej txheej yog GR3 titanium phaj, thiab lub hauv paus txheej yog Q345R steel phaj.
Base hlau thickness: 2 hli rau txheej txheej thiab 16 hli rau txheej txheej. Lub titanium muab tub lim phaj thiab titanium npog phaj yog ua los ntawm GR3 nrog lub thickness ntawm 2 hli.
6 Cov khoom siv vuam
(1) Cov khoom siv hauv paus yog carbon hlau lossis hlau tsis tshua muaj hlau. Vim muaj kev ntxhov siab, kev sib cais, cov ntsiab lus alloying thiab lwm yam laj thawj, qhov kev nyiam ntawm kev tawg yuav nce ntxiv. Txhawm rau ua kom cov vuam zoo, cov pa roj carbon steel electrode yooj yim nrog cov qauv ntawm E5015 raug xaiv los ua cov khoom siv vuam. Txhawm rau hloov mus rau qhov zawj me me thiab ua kom cov vuam ua haujlwm tau zoo, siv ob hom vuam rods nrog diameters ntawm d3.2mm thiab d4.0m.
(2) titanium txheej siv cov ntshiab titanium vuam hlau GR3ELI nrog ib txoj kab uas hla ntawm 2.0mm.
7 Groove processing thiab weld hlaws dai
Daim ntawv zawj siv hauv vuam yog qhia hauv daim duab 6. Feem ntau, cov txheej txheem txias machining tuaj yeem siv rau kev ua groove, thiab plasma arc txiav txoj kev kuj tseem siv tau. Thaum lub sij hawm groove ua, yuav tsum tau them nyiaj mloog mus rau kev tiv thaiv ntawm titanium txheej nto. Tom qab ua tiav qhov zawj, ob sab ntawm qhov zawj thiab qhov chaw ntawm titanium txheej yuav tsum raug tshuaj xyuas. Yog tias khawb lossis puas tau pom nyob rau saum npoo ntawm titanium txheej, nws yuav tsum tau kho raws sijhawm. Lub titanium clad phaj yuav tsum tau welded nrog carbon steel puag weld ua ntej, thiab titanium clad weld yuav tsum tau welded tom qab dhau qhov kev tshuaj ntsuam. Siv lub titanium composite phaj nrog lub thickness ntawm lub hauv paus steel phaj ntawm 16 hli thiab titanium clad phaj ntawm 2 hli ua piv txwv, thiab weld hlaws dai yog qhia nyob rau hauv daim duab 6.
Daim duab 6 Weld hlaws kev npaj ntawm titanium composite phaj.
