Raws li titanium alloys siv nyob rau hauv ntau yam kev siv, kev saib xyuas kuj tau them rau lawv qhov zoo thiab kav ntev. Ib txoj kev zoo melting undoubtedly muaj ib qho tseem ceeb ntawm kev siv titanium alloys. Tsib txoj kev npaj rau smelting titanium thiab titanium alloys yuav qhia hauv qab no.
1.Vacuum Consumable Arc Rauv Melting Method
Txoj kev smelting no feem ntau hu ua VAR txoj kev, thiab cov txheej txheem kev npaj electrode feem ntau siv. Nws cov txiaj ntsig tseem ceeb yog kev siv hluav taws xob tsawg, siab melting ceev thiab zoo rov ua dua tshiab, thiab cov smelted ingot kuj muaj cov qauv crystalline zoo thiab cov tshuaj muaj pes tsawg leeg. Tsis tas li ntawd, ib qho hluav taws xob arc rauv tuaj yeem tsim ntau hom ingot thiab nce qhov loj ntawm lub ingot, uas tuaj yeem txhim kho cov khoom tsim tau zoo.
2.Non-consumable Vacuum Arc Rauv Melting Method
Txoj kev no yog hu ua NC txoj kev, thiab feem ntau yog npaj los ntawm kev siv dej-txias tooj liab electrode. Qhov kom zoo dua yog tias cov txheej txheem ntawm nias electrodes thiab vuam electrodes tuaj yeem raug tshem tawm, cov nqi tsim khoom tuaj yeem raug txo, thiab kev rov ua dua ntawm titanium tuaj yeem ua tiav.
3.Cold Herth Melting Method
Txhawm rau ua kom cov titanium alloys zoo dua siv hauv thaj chaw aerospace, peb yuav tsum siv txoj hauv kev tshiab los daws qhov tsis xws luag los ntawm cov khoom siv raw khoom sib kis lossis cov txheej txheem tsim khoom txawv txav hauv cov txheej txheem smelting. Lub sijhawm no, CHM txoj kev tshwm sim. Raws li cov khoom siv hluav taws xob sib txawv, nws tuaj yeem muab faib ua electron beam smelting method thiab plasma smelting method. Qhov loj tshaj feature yog kev sib cais ntawm melting, refining thiab solidification txheej txheem, uas tuaj yeem zam kev sib kis ntawm impurities.
4.Cold Crucible Melting Method
Cov txheej txheem yog hu ua CCM txoj kev, thiab cov txheej txheem smelting yog ua nyob rau hauv ib tug hlau crucible uas muaj xws li dej-txias arc-shaped blocks los yog tooj liab raj uas tsis yog-conductive rau ib leeg. Qhov zoo yog tias tus nqi ntawm cov cuab yeej npaj tau qis thiab kev ua haujlwm yooj yim, tab sis nws tseem siv dav.
5.Electroslag Smelting Method
Txoj kev ESR yog kev siv kev sib tsoo ntawm cov khoom siv hluav taws xob thaum tam sim no dhau los ntawm cov hluav taws xob hluav taws xob ua hluav taws xob ua hluav taws xob rau smelting. Qhov zoo yog siab repeatability rau kev pom ingots, uniform crystalline qauv, siab precision khoom thiab yooj yim ua hauj lwm. Qhov tsis zoo yog tias qhov sib kis ntawm cov ingot los ntawm slag tsis tuaj yeem txiav tawm.
