TZM Alloy Production Process

Taw qhia

TZM alloy feem ntau cov txheej txheem yog hmoov metallurgy txoj kev thiab lub tshuab nqus tsev arc melting. Cov chaw tsim khoom tuaj yeem xaiv ntau txoj kev tsim khoom raws li cov khoom xav tau, txheej txheem tsim khoom thiab cov khoom siv sib txawv. TZM alloy ntau lawm txheej txheem yog raws li nram no: sib tov - nias - pre-sintering - sintering - dov-annealing -TZM alloy khoom.

Vacuum Arc Melting Method

Nqus arc melting txoj kev yog siv lub arc kom yaj ntshiab molybdenum thiab ces ntxiv ib tug npaum li cas ntawm Ti, Zr thiab lwm yam alloying ntsiab rau hauv nws. Tom qab sib tov zoo peb tau txais TZM alloy los ntawm cov txheej txheem casting. Cov txheej txheem ntawm lub tshuab nqus tsev arc smelting muaj xws li kev npaj electrode, dej txias los, ruaj khov arc sib tov thiab melting zog thiab lwm yam. Cov txheej txheem tsim khoom no muaj qee yam cuam tshuam rau TZM alloy zoo. Txhawm rau tsim cov kev ua tau zoo TZM alloy yuav tsum ua raws li cov cai nruj ntawm cov txheej txheem ntau lawm.

Electrode yuav tsum tau: cov khoom xyaw ntawm electrode yuav tsum sib xws thiab nto yuav tsum qhuav, ci, tsis muaj oxidation thiab tsis muaj dabtsi yog khoov, straightness ua raws cai.

Dej txias nyhuv: nyob rau hauv lub tshuab nqus tsev consumable smelting cub, crystallizer nyhuv feem ntau yog ob: ib tug yog tshem tawm cov cua sov tawm thaum melting, kom paub tseeb tias crystallization yuav tsis raug hlawv; lwm qhov yog cuam tshuam rau sab hauv lub koom haum ntawm TZM alloy blanks. Lub crystallizer tuaj yeem hla cov cua kub hnyav rau hauv daim ntawv dawb paug hauv qab thiab ib puag ncig, ua qhov khoob los tsim cov qauv ntawm cov kab ke. TZM alloy thaum melting, txias dej siab tswj nyob rau hauv 2.0 ~ 3.0 kg / cm², thiab txheej dej ntawm li 10mm yog qhov zoo tshaj plaws.

Ruaj khov arc sib xyaw: TZM alloy thaum lub sij hawm melting yuav ntxiv rau lub kauj uas yog sib npaug nrog crystallizer. Tom qab fais fab tuag, nws yuav dhau los ua magnetic teb. Cov txiaj ntsig ntawm qhov chaw sib nqus no feem ntau yog khi arc thiab ua kom lub pas dej molten nyob rau hauv nplawm, yog li cov nyhuv arc khi yog hu ua "ruaj khov arc." Tsis tas li ntawd, nrog kev sib nqus sib nqus siv tau tuaj yeem txo cov crystallizer tawg.

Melting zog: melting hmoov txhais tau tias melting fais fab tam sim no thiab voltage, thiab nws yog ib qho tseem ceeb ntawm cov txheej txheem tsis. Qhov tsis tsim nyog tuaj yeem ua rau TZM alloy smelting tsis ua haujlwm. Xaiv qhov tsim nyog melting zog yog loj raws li lub cev muaj zog thiab crystallizer loj piv. Qhov "L" yog hais txog qhov kev ncua deb ntawm cov electrode thiab cov phab ntsa crystallizer, tom qab ntawd tus nqi qis dua L, qhov ntau dua qhov kev pab them nqi ntawm lub arc rau lub pas dej ua ke, yog li ntawm tib cov hmoov, lub pas dej kub hauv lub xeev zoo dua thiab muaj zog dua. . Ntawm qhov tsis sib xws, kev ua haujlwm nyuaj.

Hmoov Metallurgy Method

Hmoov metallurgy txoj kev yog kom zoo sib tov siab purity molybdenum hmoov, TiH₂hmoov, ZrH₂hmoov thiab graphite hmoov, tom qab ntawd ua cov txheej txheem txias isostatic nias. Tom qab nias, sintering ntawm kev tiv thaiv roj tiv thaiv thiab kub kub tau txais TZM blanks. Lub Blank rau txheej txheem kub dov (kub forging), high-temperature annealing, nruab nrab kub dov (intermediate kub forging), nruab nrab kub annealing rau nyem nyem, sov dov (sov forging) kom tau TZM alloy (titanium zirconium molybdenum alloy). Cov txheej txheem dov (forging) thiab kev kho cua sov tom ntej plays lub luag haujlwm tseem ceeb ntawm cov khoom ntawm alloy.

Cov txheej txheem tseem ceeb yog raws li hauv qab no: sib tov → pob milling → txias isostatic nias → los ntawm hydrogen los yog lwm yam roj → sintering ntawm kub kub → TZM blanks → kub dov → high-temperature annealing → nruab nrab kub dov → nruab nrab kub annealing rau nyem qhov Kev ntxhov siab → sov dov → TZM alloy.
