TZM Alloy Production Tsari

Gabatarwa

TZM gami da hanyoyin samarwa galibi sune hanyar samar da ƙarfe na foda da hanyar narkewar iska. Masana'antu na iya zaɓar hanyoyin samarwa daban-daban bisa ga buƙatun samfur, tsarin samarwa da na'urori daban-daban. TZM gami da samar da tsarin su ne kamar haka: hadawa - latsa - pre-sintering - sintering - mirgina-annealing -TZM gami kayayyakin.

Hanyar narkewar Arc

Hanyar narkewar vacuum shine a yi amfani da baka don narke molybdenum mai tsafta sannan a ƙara wani adadin Ti, Zr da sauran abubuwan haɗakarwa a ciki. Bayan hadawa da kyau muna samun alloy na TZM ta hanyoyin simintin al'ada. Tsarin samar da injin arc smelting ya haɗa da shirye-shiryen lantarki, tasirin sanyaya ruwa, haɗaɗɗen arc barga da ƙarfin narkewa da sauransu. Wadannan hanyoyin samarwa suna da wani tasiri akan ingancin alloy na TZM. Don samar da kyakkyawan aiki TZM gami ya kamata a aiwatar da stringent buƙatu akan tsarin samarwa.

Abubuwan buƙatun Electrode: abubuwan da ke cikin lantarki yakamata su zama iri ɗaya kuma saman yakamata ya zama bushe, mai haske, babu iskar shaka kuma babu lanƙwasa, buƙatun biyan buƙatun madaidaiciya.

Tasirin sanyaya ruwa: a cikin tanderun da ake cinyewa, tasirin crystallizer yafi biyu: daya shine cire zafin da aka saki yayin narkewa, don tabbatar da cewa ba za a ƙone crystallization ba; da sauran shi ne ya shafi ciki kungiyar na TZM gami blanks. Crystallizer na iya wuce zafin dumama zuwa ƙasa mara tushe da kewaye, yin blanks don samar da tsarin ginshiƙan daidaitacce. TZM alloy yayin narkewa, sanyaya ikon sarrafa ruwa a cikin 2.0 ~ 3.0 kg / cm², kuma Layer na ruwa a kusan 10mm shine mafi kyau.

Haɗin arc mai ƙarfi: TZM gami yayin narkewa zai haɗa da nada wanda yayi daidai da crystallizer. Bayan kunna wuta, zai zama filin maganadisu. Tasirin wannan filin maganadisu shine galibi don ɗaure baka da kuma ƙarfafa tafkin narkakkar da ke ƙarƙashin motsawa, don haka tasirin daurin baka ana kiransa “stable arc.” Bugu da ƙari, tare da dacewa da ƙarfin filin maganadisu na iya rage rushewar crystallizer.

Ƙarfin narkewa: narkewar foda yana nufin narkewar wutar lantarki da ƙarfin lantarki, kuma yana da mahimmancin sigogi na tsari. Sigar da ba ta dace ba na iya haifar da gazawar TZM gami. Zaɓi ikon narkewar da ya dace ya fi dogara akan injin mota da girman girman rabo. The "L" yana nufin nisa tsakanin electrode da crystallizer bango, sa'an nan da ƙananan L darajar, mafi girma da ɗaukar hoto yanki na arc for weld pool, don haka a wannan foda, pool dumama jihar ne mafi alhẽri kuma mafi aiki. . Akasin haka, aikin yana da wahala.

Hanyar Karfe Foda

Hanyar ƙarfe ta foda ita ce haɗaɗɗen tsaftar molybdenum foda, TiH₂foda, ZrH₂foda da graphite foda, sa'an nan don aiwatar sanyi isostatic latsa. Bayan dannawa, sintering a kariyar gas mai kariya da zafin jiki mai girma sami TZM blanks. Blank don aiwatar da jujjuyawa mai zafi (ƙarfafa ƙirƙira), haɓakar zafin jiki mai ƙarfi, mirgina zafin jiki na matsakaici (matsakaicin ƙirƙira zafin jiki), matsananciyar zafin jiki na matsananciyar damuwa, jujjuyawar dumi (dumi ƙirƙira) don samun alloy na TZM (titanium zirconium molybdenum alloy). Tsarin jujjuyawar (ƙirƙira) da maganin zafi na gaba yana taka muhimmiyar rawa akan kaddarorin gami.

Babban hanyoyin samarwa sune kamar haka: hadawa → milling ball → sanyi isostatic latsa → ta hanyar hydrogen ko wasu iskar gas → rarrabuwa a yanayin zafi mai zafi → TZM blankshot → zafi mai zafi → zafi mai zafi → matsakaicin zafin jiki mirgina → matsakaicin zafin jiki na motsa jiki don taimakawa damuwa → dumin mirgina → TZM gami.
