Titanium ingot smelting technology
Kev txhim kho ntawm titanium ingot smelting technology yog ib qho teeb meem tseem ceeb hauv kev lag luam metallurgical. Titanium yog dav siv hauv aerospace, kev kho mob, tshuaj thiab lwm yam kev lag luam vim nws lub zog siab, tsis tshua muaj siab thiab zoo heev corrosion kuj. Txawm li cas los xij, titanium yog qhov nyuaj rau smelt vim nws qhov siab melting point, muaj zog tshuaj lom neeg ua haujlwm, thiab siab affinity nrog oxygen thiab nitrogen. Yog li ntawd, txoj kev loj hlob ntawm titanium ingot smelting tshuab yog ib qho tseem ceeb kom tau raws li qhov kev thov loj hlob ntawm titanium cov ntaub ntawv. Kev tsim cov titanium alloys feem ntau yog nyob ntawm titanium ingot smelting technology, uas yog txheej txheem tseem ceeb hauv kev tsim cov khoom titanium.
Muaj ntau txoj hauv kev rau melting titanium ingots, nrog rau lub tshuab nqus tsev arc melting (VAR), plasma arc melting (PAM), thiab electron beam melting (EBM). VAR yog ib txoj hauv kev siv dav hauv kev tsim cov purity titanium ingots. Thaum cov txheej txheem no, cov khoom siv titanium electrode yog yaj hauv lub tshuab nqus tsev, thiab cov titanium molten solidifies los ntawm kev txias. PAM thiab EBM yog cov txheej txheem smelting siab heev uas tuaj yeem tsim cov titanium ingots nrog cov purity siab dua thiab cov qauv zoo dua. Hauv PAM, lub plasma arc yog siv los yaj cov titanium, thaum nyob rau hauv EBM, ib tug electron beam yog siv.
Txoj kev loj hlob ntawm titanium ingot smelting tshuab suav nrog kev ua kom zoo ntawm cov khoom siv smelting, kev txhim kho cov khoom siv thiab cov txheej txheem tswj, thiab txo cov nqi tsim khoom. Optimization ntawm melting tsis muaj xws li kev hloov kho ntawm melting kub, siab thiab melting tus nqi kom ua tau raws li qhov xav tau ingot purity, qauv thiab uniformity. Kev txhim kho hauv cov cuab yeej siv thiab cov txheej txheem tswj hwm suav nrog kev tsim cov tshuab ua kom muaj kev ua tau zoo, kev txhim kho cov tshuab hluav taws xob tswj hluav taws xob, thiab kev sib koom ua ke ntawm kev saib xyuas online thiab tswj cov tshuab. Kev txo cov nqi tsim khoom suav nrog kev txo qis hauv kev siv hluav taws xob, kev siv cov khoom siv raw thiab cov nqi zog.
Smelting technology
1. Thawj kauj ruam hauv titanium alloy ingot smelting tshuab yog xaiv cov khoom siv raw. Cov ntaub ntawv nyoos yuav tsum ua kom tau raws li qhov yuav tsum tau ua kom zoo, suav nrog tshuaj lom neeg muaj pes tsawg leeg, cov ntsiab lus impurity, thiab particle loj tis. Tom qab ntawd cov ntaub ntawv raw yog thauj mus rau hauv lub qhov cub hluav taws xob.
2. Lub tshuab hluav taws xob siv rau smelting titanium ingots feem ntau yog lub tshuab nqus tsev vacuum arc rauv lossis lub qhov cub txias crucible induction. Lub tshuab nqus tsev hluav taws xob arc rauv tshuab tau dav siv thoob ntiaj teb vim nws cov kev ua haujlwm siab melting, kev ua haujlwm yooj yim thiab kev saib xyuas yooj yim. Cold crucible induction furnaces kuj yog lwm txoj hauv kev rau lub tshuab nqus tsev vacuum.
3. Thaum lub sij hawm melting txheej txheem, qhov cub kub kub nce mus rau 1500 degree -1800 degree kom yaj cov ntaub ntawv raw. Lub tshuab nqus tsev ib puag ncig yog siv los tshem tawm cov pa roj lossis impurities seem hauv cov ntaub ntawv raw thiab tiv thaiv titanium alloy los ntawm oxidizing.
Thaum cov khoom yog melted, nws yog refined siv ntau txoj kev xws li argon tshuab, nqus refining los yog slag refining. Cov txheej txheem refining no tuaj yeem txo cov pa oxygen, nitrogen thiab hydrogen cov ntsiab lus hauv titanium alloy yaj thiab txhim kho qhov zoo ntawm titanium alloy ingots.
4. Tom qab ntawd ncuav lub molten titanium alloy rau hauv preheated pwm. Txheem pwm rau titanium alloy ingots muaj xws li cylindrical thiab polygonal pwm. Cov txheej txheem casting yog nruj me ntsis tswj kom tswj tau qhov kub thiab txias ntawm lub ingot kom ntseeg tau tias cov uniformity thiab txhua yam khoom ntawm titanium alloy ingot qauv.
Ntxiv nrog rau kev tsim cov thev naus laus zis thev naus laus zis, kev rov ua dua ntawm titanium pov tseg thiab cov khoom seem kuj tseem ceeb rau kev txhim kho cov khoom siv titanium kom ruaj khov. Recycling ntawm titanium seem thiab seem tsis tsuas yog txo cov nqi tsim khoom tab sis kuj txo qhov cuam tshuam ib puag ncig ntawm titanium smelting. Kev rov ua dua ntawm titanium seem thiab cov ntaub ntawv pov tseg suav nrog kev sau, txheeb xyuas, ntxuav thiab ua cov titanium seem thiab cov khoom seem, thiab tom qab ntawd smelting thiab casting rau hauv cov khoom.
Titanium ingot smelting thev naus laus zis yog ib kauj ruam tseem ceeb hauv kev tsim cov titanium alloy. Kev xaiv zoo ntawm cov khoom siv raw, cov txheej txheem smelting, txheej txheem refining, thiab cov txheej txheem casting feem cuam tshuam rau qhov zoo ntawm titanium alloy ingots. Nrog rau kev tsim cov thev naus laus zis siab heev, cov txheej txheem smelting ntawm titanium alloy ingots tau ua haujlwm zoo dua, meej, thiab ib puag ncig tus phooj ywg, txhawb kev txhim kho thiab siv cov titanium alloys hauv ntau yam lag luam.
Vim muaj cov khoom tshwj xeeb ntawm titanium, kev txhim kho ntawm titanium ingot smelting technology yog ib txoj haujlwm nyuaj. Txawm li cas los xij, raws li kev siv thev naus laus zis thiab kev thov rau cov khoom siv titanium txuas ntxiv mus ntxiv, kev txhim kho ntawm titanium ingot smelting technology yog qhov tseem ceeb rau kev loj hlob ntawm kev lag luam titanium. Kev ua kom zoo ntawm cov khoom siv smelting, txhim kho cov cuab yeej thiab cov txheej txheem tswj, thiab rov ua dua ntawm titanium seem thiab seem yog qhov tseem ceeb hauv kev txhim kho titanium ingot smelting technology.
