Nqus Arc Remelting (VAR), raws li cov txheej txheem tseem ceeb hauv kev tsim cov titanium thiab titanium alloy ingots, muaj txoj haujlwm tsis tuaj yeem hloov pauv hauv kev lag luam siab - kawg. Cov thev naus laus zis no ua rau qhov kawg ntawm tus kheej- siv cov electrode hauv zos los ntawm cov cua sov hauv lub tshuab nqus tsev lossis cov roj tsis muaj zog tiv thaiv ib puag ncig, thiab cov molten droplets nkag mus rau hauv cov crystallizer los ua lub pas dej ua ke, thiab tom qab ntawd ua kom cov khoom sib txuas ua ke los tsim cov khoom siv hauv tsev, muab cov khoom siv zoo tshaj - lub hauv paus rau aerospace, biomedical thiab lwm yam. Hauv kev tsim khoom tiag tiag, titanium ingots feem ntau yuav tsum tau yaj ntau zaus kom ntseeg tau tias qhov sib xws ntawm cov tshuaj muaj pes tsawg leeg thiab kev ncaj ncees ntawm cov qauv, txheej txheem feem ntau 2-3 zaug. Thawj melting converts lub pressed electrode rau hauv thawj ingot, thiab ces siv lub ingot raws li ib tug self-consuming electrode rau theem nrab los yog txawm tertiary melting, uas zoo txhawb lub uniform faib ntawm cov ntsiab lus thiab tshem tawm cov metallurgical tsis xws luag los ntawm cov txheej txheem ntawm rov qab melting.
Nyob rau hauv xyoo tas los no, nrog kev nce qib ntawm kev siv tshuab, VAR thev naus laus zis tau txuas ntxiv txhim kho thiab txhim kho. Lub tshuab nqus tsev tawm tawm tus kheej-siv arc melting thiab nruam casting khoom integrates lub tshuab nqus tsev chamber, pub chamber thiab tso chamber los tsim ib tug tiav lawm system. Lub tshuab nqus tsev vacuum muab qhov tsim nyog lub tshuab nqus tsev ua haujlwm ib puag ncig rau lub tshuab melting, thiab qhov tsim nyog txheej txheej melting ntaus ntawv thiab nruam casting ntaus ntawv hauv nws paub qhov tsis siv neeg nruam zus tau tej cov titanium alloy nqus nws tus kheej-siv arc melting thiab nruam casting txheej txheem. Qhov kev tsim tshiab no tsis tsuas yog ua kom luv luv lub voj voog ntau lawm thiab txhim kho kev tsim khoom, tab sis tseem ceeb tshaj, ua kom muaj kev ruaj ntseg ntawm cov khoom siv hlau zoo ntawm cov khoom siv los ntawm kev tsim khoom.
Qhov kev thov loj zuj zus rau titanium alloys hauv siab -kawg daim ntawv thov thiab cov kev xav tau ntau ntxiv rau cov khoom siv zoo txuas ntxiv mus rau kev txhim kho VAR kev tswj hwm kev sib cais. Tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov tseem ceeb scenarios xws li aerospace cav rotating Cheebtsam thiab kev kho mob implants, tsis tshua muaj siab yuav tsum tau muab tso rau pem hauv ntej rau lub qaug zog kev kawm thiab kev cia siab ntawm titanium alloy cov ntaub ntawv, thiab cov kev tso cai segregation defect loj thiab ntau cov qauv yog tas li nruj, uas tau dhau los ua lub hauv paus tsav tsheb quab yuam ntawm technological innovation.
Nws yog tsim nyog hais tias nyob rau hauv lub tshav pob ntawm vanadium -titanium- raws li cov ntaub ntawv tshawb fawb, tseem muaj kev vam meej nyob rau hauv cov technologies. Los ntawm kev txhim kho lub tshuab nqus tsev induction suspension melting thev naus laus zis, cov kws tshawb fawb tsis yog tsuas yog kov yeej cov teeb meem ib txwm muaj xws li alloy burnout hnyav thiab crucible corrosion, tab sis kuj paub txog alloy purification muaj nuj nqi, zoo inhibiting macroscopic tivthaiv segregation. Nyob rau hauv txoj kev no, cov ntaub ntawv raw uas muaj cov ntsiab lus melting siab yog muab tso rau hauv dej -coj tooj liab crucible, thiab cov ntaub ntawv uas tsis tshua muaj melting point yog ntxiv los ntawm feeder, thiab ces sib tov thiab melted tom qab lub siab melting point cov ntaub ntawv yog tag melted, kom lub uniformity ntawm cov muaj pes tsawg leeg los ntawm rov qab melting.
Nrog rau kev nkag siab tob zuj zus ntawm kev nkag siab ntawm VAR txheej txheem thiab kev nce qib ntawm kev tswj hwm thev naus laus zis, cov khoom siv hlau zoo ntawm titanium alloy ingots tau txhim kho tsis tu ncua. Kev sib koom ua ke ntawm kev sib koom ua ke ntawm ntau- nplai simulation, kev tswj hwm ntse, VAR thev naus laus zis tshiab thiab kev soj ntsuam online yog txhawb nqa titanium alloy VAR melting thev naus laus zis mus rau qib siab dua. Kev sib koom ua ke thiab kev tsim kho tshiab ntawm cov thev naus laus zis no yuav ua tau zoo dua qhov kev xav tau ntawm titanium alloy cov ntaub ntawv hauv high -kawg teb xws li aerospace thiab biomedicine, thiab muab cov khoom muaj zog txhawb kev tsim kho dua tshiab. Los ntawm kev txhim kho thev naus laus zis thiab kev tsim kho tshiab tas li, lub tshuab nqus tsev tus kheej-siv cov thev naus laus zis yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev lag luam siab - kawg kev lag luam yav tom ntej, txhaj tshuaj tshiab tseem ceeb rau hauv kev nce qib ntawm Tuam Tshoj cov khoom lag luam tshiab.
