Mutu: Kufunika Kwa Mavuni Opangira Vuto mu Zosakaniza Zosungunulira

Mukasungunula ma alloys, njirayi imafunikira kulondola komanso kuwongolera kuti zitsimikizire kuti zomwe mukufuna zikwaniritsidwa.Mbali yofunika kwambiri ya njirayi ndikugwiritsa ntchito ng'anjo ya vacuum induction.Ng'anjozi zimagwira ntchito yofunika kwambiri posungunula ma aloyi osiyanasiyana, chilichonse chimakhala ndi zofunikira zake.Mu blog iyi, tiwona mitundu yosiyanasiyana ya ma alloys omwe amafunikira kusungunuka mu ang'anjo ya vacuum inductionndi zifukwa zomwe zimawapangitsa kukhala ofunikira.

Chimodzi mwazitsulo zodziwika bwino zosungunulidwa pogwiritsa ntchito ng'anjo ya vacuum induction ndi chitsulo chosapanga dzimbiri.Chitsulo chosapanga dzimbiri ndi aloyi yosunthika yomwe imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuchokera ku zida zakukhitchini kupita kumakina ogulitsa.Njira yosungunulira zitsulo zosapanga dzimbiri zimafuna kuwongolera bwino kapangidwe ka aloyi ndi kuchotsa zonyansa monga kaboni ndi sulfure.Miyendo yosungunula vacuum imapereka malo abwino osungunulira zitsulo zosapanga dzimbiri chifukwa amatha kuwongolera bwino kutentha ndi mpweya panthawi yosungunulira.

Chigawo china chofunikira chomwe chimasungunuka pogwiritsa ntchito ng'anjo ya vacuum ndi platinamu-rhodium alloy.Platinamu-rhodium alloy imadziwika chifukwa cha kuchuluka kwa mphamvu ndi kulemera kwake komanso kukana kwa dzimbiri, zomwe zimapangitsa kuti ikhale yofunika kwambiri m'mafakitale monga zakuthambo ndi zida zamankhwala.Kusungunula platinamu-rhodium alloy kumafuna kuyeretsedwa kwakukulu chifukwa ngakhale zonyansa zazing'ono zimatha kukhudza kwambiri katundu wake.Zida zopangira vacuum zimatha kupanga malo oyera kwambiri omwe amafunikira kuti asungunuke aloyi ya platinamu-rhodium, zomwe zimawapangitsa kukhala ofunika kwambiri popanga aloyi wofunikira.

M'makampani azamlengalenga, ma superalloys amafunikira kwambiri kuti athe kupirira kutentha kwambiri komanso kupsinjika kwamakina.Ma aloyiwa amagwiritsidwa ntchito popanga masamba a turbine, zida za injini ndi zida zina zofunika kwambiri pa ndege ndi zakuthambo.Kusungunula ma alloys otentha kwambiri monga Inconel ndi Hastelloy kumafuna kuwongolera kolondola kwa njira zosungunulira ndi zolimba komanso kuchotsa zonyansa.Ma ng'anjo a vacuum induction ng'anjo amapereka zofunikira zosungunula ma alloys otentha kwambiri kuti apange zida zapamwamba kwambiri zogwirira ntchito zamlengalenga.

M'makampani amagalimoto, ma aluminiyamu aloyi amagwiritsidwa ntchito kwambiri chifukwa chopepuka komanso chosagwira dzimbiri.Kusungunula ma aluminiyamu aloyi kumafuna kuwongolera mosamalitsa njira zosungunulira ndi zoponyera kuti zitsimikizire kuti zomwe mukufuna zimakwaniritsidwa.Ma ng'anjo a vacuum amawongolera kutentha ndi mpweya wofunikira kuti asungunuke zotayira za aluminiyamu, zomwe ndizofunikira kwambiri popanga zida zamagalimoto apamwamba kwambiri.

M'makampani azachipatala, ma alloys a biocompatible monga ma aloyi a titaniyamu ndi aloyi a cobalt-chromium amagwiritsidwa ntchito popanga ma implants ndi zida zamankhwala.Kusungunula ma aloyiwa kumafuna chiyero chapamwamba komanso kuwongolera kapangidwe kake kuti zitsimikizire kuti zikukwaniritsa zofunikira za biocompatibility ndi makina amakina.Ma ng'anjo opangira vacuum amapereka mikhalidwe yofunikira kuti asungunuke ma alloys a biocompatible, kuwapangitsa kukhala ofunikira popanga zida zamankhwala.

M'makampani amagetsi, ma alloys amkuwa amagwiritsidwa ntchito popanga magetsi komanso matenthedwe.Kusungunula ma aloyi amkuwa kumafuna kuwongolera bwino kwa kapangidwe kake ndikuchotsa zonyansa kuti zitsimikizire kuti zinthu zomwe zimafunikira zamagetsi ndi zamakina zimakwaniritsidwa.Mavuni opangira ng'anjo amapereka malo abwino osungunula ma alloys amkuwa kuti apange zida zapamwamba kwambiri pamagetsi.

Mwachidule, ng'anjo za vacuum induction zimagwira ntchito yofunika kwambiri pakusungunula ma alloys osiyanasiyana, iliyonse ili ndi zofunikira zake.Kuchokera ku zitsulo zosapanga dzimbiri kupita ku titaniyamu, kuchokera kuzitsulo zotentha kwambiri mpaka kuzitsulo za aluminiyamu, kuchokera kuzitsulo zosakanikirana ndi biocompatible kupita kuzitsulo zamkuwa, ng'anjozi zimapereka zofunikira zopangira zipangizo zamakono zamafakitale osiyanasiyana.Kuwongolera kutentha, mlengalenga ndi chiyero zomwe zimatheka chifukwa cha kusungunula kwa vacuum ndizofunikira kwambiri kuti zikwaniritse zofunikira zazitsulo zamakono.Pamene ukadaulo ukupitilirabe patsogolo, ntchito ya ng'anjo za vacuum mu smelting ya alloy ikhala yofunika kwambiri pakukwaniritsa zosowa zamafakitale osiyanasiyana.
