Ts'ebetso ea Tlhahiso ea Alloy ea TZM

Selelekela

TZM alloy hangata mekhoa ea tlhahiso ke mokhoa oa metallurgy oa phofo le mokhoa oa ho qhibiliha oa vacuum arc. Baetsi ba ka khetha mekhoa e fapaneng ea tlhahiso ho latela litlhoko tsa sehlahisoa, ts'ebetso ea tlhahiso le lisebelisoa tse fapaneng. Mekhoa ea tlhahiso ea motsoako oa TZM e tjena: ho kopanya – ho hatella – pre-sintering – sintering – rolling-annealing -TZM alloy products.

Mokhoa oa ho qhibiliha oa Vacuum Arc

Mokhoa oa ho qhibilihisa arc ea vacuum ke ho sebelisa arc ho qhibilihisa molybdenum e hloekileng ebe o eketsa palo e itseng ea Ti, Zr le likarolo tse ling tsa motsoako ho eona. Ka mor'a ho kopanya hantle re fumana motsoako oa TZM ka mekhoa e tloaelehileng ea ho lahla. Ts'ebetso ea tlhahiso ea vacuum arc smelting e kenyelletsa ho lokisoa ha li-electrode, liphello tsa ho pholisa metsi, ho kopanya li-arc tse tsitsitseng le matla a ho qhibiliha joalo-joalo. Mekhoa ena ea tlhahiso e na le phello e itseng ho boleng ba alloy ea TZM. Bakeng sa ho hlahisa ts'ebetso e ntle, motsoako oa TZM o lokela ho phethahatsa litlhoko tse thata ts'ebetsong ea tlhahiso.

Litlhoko tsa electrode: metsoako ea electrode e lokela ho tšoana le bokaholimo e lokela ho ba o omileng, o khanyang, o se na oxidation le ho se kobehe, litlhoko tsa ho otloloha tsa ho latela.

Phello ea ho pholisa metsi: ka vacuum consumable smelting sebōpi, phello ea crystallizer haholo-holo tse peli: e 'ngoe ke ho tlosa mocheso o lokollotsoeng nakong ea ho qhibiliha, ho etsa bonnete ba hore crystallization e ke ke ea chesoa; e 'ngoe ke ho ama mokhatlo o ka hare oa likheo tsa motsoako oa TZM. Crystallizer e ka fetisa mocheso o matla ho ea boemong bo se nang letho ka tlase le ho pota-pota, e etsa likheo ho hlahisa sebopeho sa columnar. TZM alloy nakong ea ho qhibiliha, ho laola khatello ea metsi a pholileng ka 2.0 ~ 3.0 kg / cm², 'me lera la metsi le ka bang 10mm ke lona le molemo ka ho fetisisa.

Motsoako o tsitsitseng oa arc: Alloy ea TZM nakong ea ho qhibiliha e tla kopanngoa le khoele e bapileng le kristallizer. Kamora ho sebetsa, e tla fetoha sebaka sa makenete. Phello ea matla ana a khoheli haholo-holo ke ho tlama arc le ho tiisa letamo le qhibilihisitsoeng tlas'a ho sisinyeha, kahoo phello e tlamang ea arc e bitsoa "stable arc." Ho feta moo, ka matla a matla a khoheli a loketseng a ka fokotsa ho senyeha ha crystallizer.

Matla a ho qhibiliha: phofo e qhibilihang e bolela matla a qhibilihang hona joale le motlakase, 'me ke mekhoa ea bohlokoa ea ts'ebetso. Mekhatlo e sa nepahalang e ka baka ho hloleha ho qhibilihisa alloy ea TZM. Khetha matla a nepahetseng a ho qhibiliha a ipapisitse le tekanyo ea boholo ba motlakase le kristale. "L" e bolela sebaka se pakeng tsa electrode le lerako la crystallizer, ebe boleng bo tlaase ba L, sebaka se seholo sa tšireletso ea arc bakeng sa letamo la weld, kahoo ka phofo e tšoanang, boemo ba ho futhumatsa letamo bo molemo ebile bo sebetsa haholoanyane. . Ho fapana le hoo, ho buuoa ho thata.

Mokhoa oa Metallurgy oa Powder

Mokhoa oa metallurgy oa phofo ke ho kopanya hantle phofo e phahameng ea molybdenum, TiH₂phofo, ZrH₂phofo le phofo ea graphite, ebe o sebetsana le khatello e batang ea isostatic. Kamora ho hatella, sintering ka tšireletso ea khase e sirelletsang le mocheso o phahameng o fumana likheo tsa TZM. The Blank ho sebetsana le hot-rolling (hot forging), annealing high-themperature, the medium of the intermediary (intermediate forging forging), the intermediate the internealing annealing to relief stress, warm rolling (mofuthu forging) ho fumana TZM alloy (titanium zirconium molybdenum alloy). Ts'ebetso ea ho roala (ho forging) le kalafo e latelang ea mocheso e phetha karolo ea bohlokoa ho thepa ea alloy.

Mehato ea mantlha ea tlhahiso ke e latelang: ho kopanya→ ho sila libolo → ho hatella ho batang ka isostatic→ka hydrogen kapa khase e' ngoe e sireletsang → ho sintering ka mocheso o phahameng → likheo tsa TZM → ho chesa ho chesang → mocheso o phahameng oa mocheso → mocheso o bohareng → mocheso o bohareng oa ho imolla khatello ea kelello→ ho bilika ho futhumetseng → motsoako oa TZM.
