Inqubo Yokukhiqiza Ingxubevange ye-TZM

Isingeniso

Ingxubevange ye-TZM ngokuvamile izindlela zokukhiqiza yindlela ye-powder metallurgy kanye nendlela yokuncibilikisa i-vacuum arc. Abakhiqizi bangakhetha izindlela ezihlukene zokukhiqiza ngokuya ngezidingo zomkhiqizo, inqubo yokukhiqiza kanye namadivayisi ahlukene. Izinqubo zokukhiqiza ingxubevange ye-TZM zimi kanje: ukuxuba – ukucindezela – pre-sintering – sintering – rolling-annealing -TZM imikhiqizo yengxubevange.

Indlela yokuncibilika kwe-Vacuum Arc

Indlela yokuncibilikisa i-vacuum arc ukusebenzisa i-arc ukuncibilikisa i-molybdenum ehlanzekile bese wengeza inani elithile le-Ti, i-Zr nezinye izakhi ze-alloying kuyo. Ngemva kokuxuba kahle sithola ingxubevange ye-TZM ngezindlela ezivamile zokulingisa. Inqubo yokukhiqiza ye-vacuum arc smelting ihlanganisa ukulungiswa kwe-electrode, imiphumela yokupholisa amanzi, ukuxuba kwe-arc okuzinzile namandla okuncibilika nokunye. Lezi zinqubo zokukhiqiza zinomthelela othize kukhwalithi ye-alloy ye-TZM. Ukuze kukhiqizwe ukusebenza kahle ingxubevange ye-TZM kufanele yenze izidingo eziqinile enqubweni yokukhiqiza.

Izidingo ze-Electrode: izithako ze-electrode kufanele zifane kanye nendawo engaphezulu kufanele yome, ikhanye, ingabi ne-oxidation futhi ingagobi, izidingo zokuthobela ubuqotho.

Umphumela wokupholisa amanzi: ku-vacuum consumable smelting esithandweni, umphumela we-crystallizer ikakhulukazi ezimbili: eyodwa iwukususa ukushisa okukhishwe ngesikhathi sokuncibilika, ukuze kuqinisekiswe ukuthi i-crystallization ngeke ishiswe; enye iwukuthinta inhlangano yangaphakathi ye-TZM alloy blanks. I-crystallizer ingakwazi ukudlulisa ukushisa okunamandla endaweni engenalutho ngaphansi nangaphansi, okwenza izikhala ukuze kukhiqizwe isakhiwo sekholomu. Ingxubevange ye-TZM ngesikhathi sokuncibilika, izilawuli zokupholisa ingcindezi yamanzi ku-2.0 ~ 3.0 kg / cm², futhi ungqimba lwamanzi cishe ngo-10mm lungcono kakhulu.

Ukuxuba i-arc okuzinzile: Ingxubevange ye-TZM ngesikhathi sokuncibilika izohlanganisa ikhoyili ehambisana necrystallizer. Ngemva kokukhanyisa, izoba inkambu kazibuthe. Umthelela wale nkundla kazibuthe ngokuyinhloko uwukubopha i-arc kanye nokuqinisa ichibi elincibilikisiwe ngaphansi kokunyakaziswa, ngakho umphumela wokubopha i-arc ubizwa ngokuthi “i-arc ezinzile.” Ngaphezu kwalokho, ngokuqina kwenkundla kazibuthe efanelekile kunganciphisa ukuwohloka kwe-crystallizer.

Amandla ancibilikisayo: impushana encibilikayo isho amandla ancibilikayo wamanje kanye ne-voltage, futhi kuyinqubo ebalulekile nemingcele. Amapharamitha angalungile angabangela ukwehluleka ukuncibilikisa ingxubevange ye-TZM. Khetha amandla afanele okuncibilika asekelwe kakhulu esilinganisweni sikasayizi wemoto nekristali. I-"L" ibhekisela ebangeni eliphakathi kwe-electrode nodonga lwe-crystallizer, khona-ke inani eliphansi le-L, indawo enkulu yokumboza i-arc ye-weld pool, ngakho-ke kumpushana ofanayo, isimo sokushisa ichibi singcono futhi sisebenza kakhulu. . Kunalokho, ukuhlinzwa kunzima.

Indlela ye-Powder Metallurgy

Indlela ye-powder metallurgy iwukuxuba kahle ubumsulwa obuphezulu be-molybdenum powder, i-TiH₂powder, ZrH₂powder kanye ne-graphite powder, bese ukucubungula ukucindezela okubandayo kwe-isostatic. Ngemuva kokucindezela, i-sintering ekuvikelweni kwegesi evikelayo kanye nokushisa okuphezulu kuthola izikhala ze-TZM. Okungenalutho ukucubungula i-hot-rolling (i-hot forging), ukudonsa izinga lokushisa eliphezulu, ukuginqika kwamazinga okushisa aphakathi nendawo (izinga lokushisa eliphakathi nendawo), ukushisa okuphakathi nendawo ekucindezelekeni kokukhululeka, ukugoqa okufudumele (ukubumba okufudumele) ukuze kutholwe ingxubevange ye-TZM (titanium zirconium molybdenum alloy). Inqubo yokugoqa (yokwenza) kanye nokwelashwa kokushisa okulandelayo kudlala indima ebalulekile ezakhiweni zengxubevange.

Izinqubo zokukhiqiza eziyinhloko zimi kanje: ukuxuba→ ukugaya ibhola →ukucindezela okubandayo kwe-isostatic→nge-hydrogen noma enye igesi evikelayo→ukucwilisa emazingeni okushisa aphezulu→izikhala ze-TZM→ukugingqika okushisayo→izinga lokushisa eliphezulu→izinga lokushisa eliphakathi nendawo→izinga lokushisa eliphakathi nendawo ukukhulula ukucindezeleka→ukugoqa okufudumele →ingxubevange ye-TZM.
