Titanium thiab Titanium Alloy Melting Technology
Titanium thiab titanium alloys tau dhau los ua qhov tseem ceeb "cov ntaub ntawv super" hauv aerospace, kev kho mob, tshuaj thiab lwm yam kev lag luam nrog lawv cov khoom tshwj xeeb - lub teeb yuag, siab zog thiab corrosion kuj. Thiab tag nrho cov kev ua tiav ci ntsa iab no tsis tuaj yeem sib cais los ntawm cov thev naus laus zis tseem ceeb - titanium thiab titanium alloy smelting technology. Kev siv thev naus laus zis ntawm titanium thiab titanium alloys yog ib kauj ruam tseem ceeb hauv kev txiav txim siab cov khoom sib xyaw thiab cov qauv, thiab tseem ceeb heev rau kev txhim kho kev ua haujlwm ntawm titanium alloys.
1. Vacuum consumable arc melting (VAR)
Qhov no yog ib tug smelting tshuab nqa tawm nyob rau hauv lub nqus tsev vacuum, uas melts cov hlau los ntawm lub zog ntawm lub arc. VAR thev naus laus zis feem ntau yog siv los yaj cov hlau ua haujlwm thiab cov hlau refractory, xws li titanium, zirconium, molybdenum, thiab lwm yam, thiab tseem tsim nyog rau cov cua sov-resistant steel, stainless hlau, thiab lwm yam. VAR furnaces tuaj yeem tsim qhov loj thiab loj-tonnage. hlau ingots, thiab cov hlau tsis muaj paug thaum lub sij hawm smelting txheej txheem, nrog cov qauv zoo, tsis shrinkage thiab ntom. Vim tias cov khoom sib xyaw ntab tuaj thaum lub sij hawm smelting, qee qhov kev suav nrog tej zaum yuav muaj zog thaum kawg ntawm qhov ingot. VAR thev naus laus zis tau siv los tshem tawm cov hlau kub kub thaum ntxov xyoo 1950, uas qhia tau zoo tshaj plaws thiab dhau los ua ib qho tseem ceeb ntawm kev tshem tawm cov kub kub thiab cov hlau tshwj xeeb.
2. Electron beam txias hearth melting (EBM)
EBM thev naus laus zis siv cov kab hluav taws xob hluav taws xob ntws hauv qab lub tshuab nqus tsev siab ua qhov cua sov rau cov hlau yaj. Cov cuab yeej no tuaj yeem muab cov hlau purity siab thiab tshwj xeeb tshaj yog tsim rau cov hlau refractory thiab cov hlau purity siab. Thaum lub sij hawm EBM txheej txheem, lub melting thiab solidification ntawm cov hlau yog nqa tawm nyob rau hauv ib tug dej-txias tooj liab crucible, uas yuav ua tau zoo tiv thaiv cov hlau molten los ntawm kis los ntawm cov ntaub ntawv refractory, yog li tau txais ib tug uniform, shrinkage-dawb thiab ntom ingot. EBM Technology muaj cov txiaj ntsig tshwj xeeb hauv kev tshem tawm siab thiab qis tsis muaj txiaj ntsig, yog li nws tau siv dav hauv lub suab nkauj ntawm titanium thiab titanium alloys.
3. Plasma beam txias hearth melting (PAM)
PAM thev naus laus zis siv plasma arc ua qhov cua sov kom yaj, ua kom zoo dua qub thiab rov ua cov hlau. Piv nrog EBM, PAM siv cov cua inert nyob ze rau atmospheric siab, uas tuaj yeem tiv thaiv cov volatilization ntawm cov ntsiab lus volatile heev thiab yog tsim rau melting heev alloyed thiab complex alloyed titanium alloys. PAM thev naus laus zis muaj cov yam ntxwv ntawm lub zog muaj zog thiab cov kab sib luag arc, uas tuaj yeem muab kev sib xyaw zoo dua thaum lub sij hawm melting thiab pab kom homogenize cov alloy muaj pes tsawg leeg. PAM thev naus laus zis tuaj yeem tshem tawm ntau yam kev suav nrog hauv titanium alloy smelting thiab txhim kho cov purity ntawm cov hlau.
4. Dej-txias crucible induction melting (CCIM)
Cov tshuab no siv cov cua sov induction kom yaj hauv cov dej-txias tooj liab crucible. CCIM tuaj yeem yaj thiab ua cov ntaub ntawv nyob rau hauv ib puag ncig yam tsis muaj cov khoom siv crucible muaj kuab paug, vim tias cov yaj thiab cov phab ntsa crucible nyob rau hauv lub xeev tsis sib cuag, thiab cov phab ntsa crucible kub yog nyob rau hauv lub txias txias, tsis txhob muaj kev sib cuam tshuam ntawm yaj thiab crucible phab ntsa. . Cov tshuab no yog tsim rau smelting ntawm cov hlau nquag thiab tuaj yeem muab cov ntaub ntawv ntshiab heev.
5. Electroslag remelting (ESR)
ESR yog cov txheej txheem refining uas siv slag kuj tshav kub rau theem nrab remelting. Cov cuab yeej no tuaj yeem tsim cov hlau ingots nrog siab purity, ntom qauv thiab cov khoom sib xws. Thaum lub sij hawm ESR txheej txheem, cov tee hlau hla dhau lub pas dej slag mus rau hauv lub pas dej hlau molten. Vim yog cov nyhuv txias ntawm cov dej-txias crystallizer, cov kua hlau ua kom sai sai los ua ib qho ingot. Cov khoom siv electroslag remelting ntau yam yog dav thiab daim ntawv thov ntau yog dav, haum rau ntau hom hlau alloy steels, high-temperature alloys, thiab lwm yam.
6. Xaiv Laser Melting (SLM)
SLM thev naus laus zis yog kev tsim khoom siv ntxiv tsim nyog rau kev tsim khoom ncaj qha ntawm titanium thiab titanium alloys. SLM siv laser ua lub zog los luam theej duab cov hlau hmoov txheej txheej txheej raws li 3D CAD qauv, kom cov hmoov hlau yog melted, solidified thiab metallurgically bonded thaum kawg tsim cov hlau tsim. Kev thev naus laus zis tuaj yeem tsim cov hlau sib xyaw nrog cov duab hlau, thiab cov seem muaj ze li cov qauv tuab thiab cov kws kho zoo.
Txhua lub tshuab melting muaj nws qhov tshwj xeeb zoo thiab daim ntawv thov scenarios. Xaiv txoj kev siv tshuab melting yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm ntawm titanium alloys. Titanium thiab titanium alloy melting tshuab yog crystallization ntawm science thiab technology thiab innovation, thiab tus choj ntawm kev npau suav thiab kev muaj tiag. Nrog nws qhov tshwj xeeb ntxim nyiam thiab qhov ua tau tsis kawg, nws ua rau peb mus rau yav tom ntej zoo dua.
