Thaum smelting titanium thiab titanium alloy ingots siv lub tshuab nqus tsev consumable arc rauv, yog tias qee yam tsis tau tswj kom zoo, qhov tsis xws luag xws li txias kaw, suav nrog, thiab porosities tuaj yeem tsim rau saum npoo ntawm cov khoom siv. Txhawm rau tiv thaiv cov teeb meem no thiab txhim kho qhov zoo ntawm metallurgical zoo ntawm titanium thiab titanium alloy ingots, tshwj xeeb yuav tsum tau them rau plaub yam hauv qab no hauv kev tsim khoom:
Plaub yam ntawm Titanium thiab Titanium Alloy Ingots nyob rau hauv ntau lawm
Ua kom muaj cov tshuaj sib xyaw ua ke uas cov ntsiab lus ntawm ntau yam alloying ntsiab lus tsis tsuas yog ua tau raws li cov qauv kev cai, tab sis kuj tseem tswj tau zoo nyob rau qib siab.
Tswj cov ntsiab lus ntawm cov impurities loj xws li Fe, O, thiab lwm yam, nyob rau hauv qhov tsim nyog, thaum xyuas kom meej tias lwm yam impurities ua raws li tus qauv yuav tsum tau ua.
Xyuas kom tsis muaj impurities, cais, roj porosity, tawg, shrinkage, thiab looseness nyob rau hauv lub ingots.
Ua kom lub ntsej muag du rau cov ingots yam tsis muaj qhov txias txias, wrinkles, lossis lwm yam tsis xws luag. Txo tus nqi ntawm lub taub hau shrinkage thiab ua tiav cov txiaj ntsig siab ntawm cov khoom tiav tiav.
Txhawm rau kom muaj kev tswj xyuas zoo ntawm txhua tus txheej txheem tsim khoom rau plaub yam saum toj no, nws yog ib qho tseem ceeb uas yuav tsum tau tsom mus rau kev tswj xyuas zoo ntawm txhua theem ntawm kev tsim khoom.
1
Kev xaiv raw khoom
Cov ntaub ntawv tseem ceeb rau titanium alloy ingot casting yog titanium daim txhuam cev thiab cov hlau nruab nrab. Nyob rau hauv ntau lawm, sieving txoj kev yog ua hauj lwm los tshem tawm ntau heev loj thiab me me titanium daim txhuam cev hais, kom ntseeg tau ib tug ntau uniform particle loj tis.
2
Sib tov
Ua ntej, cov tshuaj muaj pes tsawg leeg ntawm ingot yuav tsum tau txiav txim siab. Cov ntsiab lus tseem ceeb yuav tsum coj mus rau hauv tus account ob sab sauv thiab qis qis, sib zog ua kom ze rau qhov txiaj ntsig ntawm lub hom phiaj kom ze li sai tau. Cov ntsiab lus impurity yuav tsum tau khaws cia kom tsawg li tsawg tau thiab yuav tsum tsis txhob tshaj cov nqi teev tseg.
3
Mixing thiab Compression
Txhawm rau kom ntseeg tau tias cov tshuaj muaj pes tsawg leeg tsis sib xws hauv tib lub ingot mus rau qhov loj tshaj plaws, nws yog ib qho tsim nyog los homogenize cov ntaub ntawv raw los ntawm kev sib tov. Cov khoom sib xyaw sib xyaw ua ke yog tom qab ntawd compressed rau hauv electrode blocks siv lub tshuab roj nias.
4
Kev npaj electrode
Cov electrode blocks, tom qab sib dhos thiab vuam, ua rau cov khoom siv hluav taws xob rau thawj txheej txheem melting. Vuam txoj kev feem ntau koom nrog hydrogen arc vuam los yog plasma vuam. Thaum lub sij hawm vuam, kev tiv thaiv tsim nyog yuav tsum tau siv, zoo dua nyob rau hauv qhov chaw tsis muaj roj cua lossis hauv lub vuam chamber, txhawm rau tiv thaiv kev tsim cov oxides refractory thiab nitrides.
5
Txheej txheem melting
Cov txheej txheem melting sawv ua ib theem tseem ceeb hauv tag nrho cov khoom ntawm titanium thiab titanium alloy ingots. Cov txheej txheem tseem ceeb cuam tshuam rau qhov zoo ntawm cov khoom siv thaum lub sij hawm melting xws li tam sim no, voltage, ruaj khov arc tam sim no magnitude, thiab lub sij hawm ntawm ruaj khov arc stirring.
