TZM Alloy Kugadzira Maitiro
Nhanganyaya
TZM alloy kazhinji nzira dzekugadzira iupfu metallurgy nzira uye vacuum arc yekunyungudutsa nzira.Vagadziri vanogona kusarudza nzira dzakasiyana dzekugadzira zvinoenderana nezvinodiwa zvechigadzirwa, maitiro ekugadzira uye akasiyana michina.TZM alloy kugadzira maitiro ndeaya anotevera: kusanganisa - kudzvanya - pre-sintering - sintering - rolling-annealing -TZM alloy zvigadzirwa.
Vacuum Arc Melting Method
Vacuum arc kunyunguduka nzira ndeye kushandisa arc kunyungudutsa yakachena molybdenum uyezve kuwedzera imwe huwandu hweTi, Zr uye zvimwe alloying zvinhu mairi.Mushure mekusanganisa zvakanaka tinowana TZM alloy neyakajairwa nzira dzekukanda.Iyo yekugadzira nzira yevacuum arc kunyungudutsa inosanganisira electrode kugadzirira, kutonhora kwemvura mhedzisiro, yakagadzikana arc kusanganisa uye kunyungudika simba uye zvichingodaro.Aya maitiro ekugadzira ane imwe mhedzisiro paTZM alloy mhando.Kuti ibudise kuita kwakanaka TZM alloy inofanirwa kuita zvakaomesesa zvinodiwa pakugadzira maitiro.
Electrode zvinodiwa: izvo zvinongedzo zve electrode zvinofanirwa kuita yunifomu uye kumusoro kunofanirwa kunge kwakaoma, kupenya, pasina oxidation uye pasina kubhenda, kutwasanuka kwekutevedzera zvinodiwa.
Mvura inotonhorera mhedzisiro: muvacuum consumable smelting furnace, crystallizer mhedzisiro inonyanya maviri: imwe ndeyekubvisa kupisa kunoburitswa panguva yekunyunguduka, kuve nechokwadi chekuti crystallization haizopiswa;imwe yacho ndeye kukanganisa mukati mesangano reTZM alloy blanks.Iyo crystallizer inogona kupfuudza kupisa kwakanyanya kune isina chinhu fomu pasi nekutenderedza, ichiita mablanks kuburitsa yakamisikidzwa columnar chimiro.TZM alloy panguva yekunyunguduka, kutonhora kwemvura inodzvinyirira inodzora mu2.0 ~ 3.0 kg / cm2, uye mvura yemvura inenge 10mm ndiyo yakanakisisa.
Yakagadzikana arc musanganiswa: TZM alloy panguva yekunyunguduka ichawedzera coil inofambirana necrystallizer.Mushure mesimba, rinova remagineti.Mhedzisiro yeiyi magineti inonyanya kusunga arc uye kuomesa dziva rakanyungudutswa pasi pekubvongodza, saka iyo arc inosunga mhedzisiro inonzi "yakagadzikana arc."Uyezve, neakakodzera magineti kusimba kunogona kuderedza crystallizer kuparara.
Kunyunguduka simba: kunyunguduka poda zvinoreva kunyunguduka simba ikozvino uye voltage, uye yakakosha maitiro paramita.Maparamita asina kufanira anogona kukonzera TZM alloy kunyungudutsa kutadza.Sarudza iyo yakakodzera simba rekunyungudika rinonyanya kuenderana nemota uye crystallizer saizi reshiyo.I "L" inoreva kureba pakati pe electrode uye crystallizer wall, ipapo iyo yakaderera L kukosha, iyo yakakura yekuvhara nzvimbo yearc ye weld pool, saka panguva imwechete yehupfu, dziva rekupisa mamiriro ari nani uye rinonyanya kushanda. .Mukupesana, kuvhiya kwakaoma.
Powder Metallurgy Method
Powder metallurgy nzira ndeyekusanganisa yakakwira kuchena molybdenum poda, TiH2hupfu, ZrH2poda uye graphite poda, wozogadzira inotonhora isostatic kudzvanya.Mushure mekudzvanya, kunyura pakudzivirira gasi rekudzivirira uye tembiricha yakanyanya kuwana TZM blanks.The Blank kugadzirisa kupisa-kukungurutsira (kupisa kupisa), kukwirisa-tembiricha, kutenderedza tembiricha (yepakati tembiricha forging), yepakati tembiricha inokonzeresa kushushikana kwekunetseka, kudziya kutenderedza (inodziya forging) kuwana TZM alloy (titanium zirconium molybdenum alloy).Iyo rolling (forging) process uye inotevera kupisa kurapwa inoita basa rakakosha pazvinhu zvealloy.
Maitiro makuru ekugadzira ndeaya anotevera: kusanganisa→ kugaya bhora →kutonhora isostatic kudzvanya→kuburikidza nehydrogen kana imwe gasi rinodzivirira→kunyura patembiricha yakakwira→ZM blanks→kuyungura kunopisa→kunyunguduka kwepamusoro-tembirichakukunguruka→tembiricha yepakati-pakati inonyungudika kushushikana → inodziya kukunguruka → TZM alloy.
