Mutu: Kufunika kwa Ma uvuni Opangira Vacuum mu Smelting Alloys

Poyenga zitsulo zosungunulira, njirayi imafuna kulondola ndi kuwongolera kuti zitsimikizire kuti zinthu zomwe mukufuna zakwaniritsidwa. Mbali yofunika kwambiri pa njirayi ndikugwiritsa ntchito ng'anjo yopangira vacuum. Zitofu zimenezi zimagwira ntchito yofunika kwambiri pakuyenga zitsulo zosiyanasiyana, chilichonse chili ndi zofunikira zake zapadera. Mu blog iyi, tifufuza mitundu yosiyanasiyana ya zitsulo zomwe zimafunika kusungunulira mung'anjo yopangira vacuumndi zifukwa zomwe zimawapangitsa kufunikira.

Chimodzi mwa zinthu zosungunuka zomwe zimagwiritsidwa ntchito kwambiri pogwiritsa ntchito uvuni wa vacuum induction ndi chitsulo chosapanga dzimbiri. Chitsulo chosapanga dzimbiri ndi chinthu chosungunuka chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana, kuyambira zida za kukhitchini mpaka makina a mafakitale. Njira yosungunula chitsulo chosapanga dzimbiri imafuna kuwongolera bwino kapangidwe ka alloy ndikuchotsa zonyansa monga kaboni ndi sulfure. Zitsulo zosungunuka za vacuum zimapereka malo abwino kwambiri osungunula chitsulo chosapanga dzimbiri chifukwa zimatha kuwongolera kutentha ndi mlengalenga panthawi yosungunula.

Chitsulo china chofunika chomwe chimasungunuka pogwiritsa ntchito ng'anjo yopangira vacuum ndi platinum-rhodium alloy. Chitsulo cha platinum-rhodium chimadziwika chifukwa cha mphamvu zake zazikulu ndi kulemera kwake komanso kukana dzimbiri, zomwe zimapangitsa kuti chikhale chinthu chamtengo wapatali m'mafakitale monga ndege ndi zida zamankhwala. Kusungunula chitsulo cha platinum-rhodium kumafuna kuyera kwambiri chifukwa ngakhale zinyalala zazing'ono zingakhudze kwambiri mawonekedwe ake. Zitsulo zopangira vacuum zimatha kupanga malo oyera kwambiri omwe amafunikira kuti asungunule chitsulo cha platinum-rhodium, zomwe zimapangitsa kuti zikhale zofunika kwambiri popanga chitsulo chamtengo wapatalichi.

Mu makampani opanga ndege, ma superalloy amafunidwa kwambiri chifukwa amatha kupirira kutentha kwambiri komanso kupsinjika kwa makina. Ma alloy amenewa amagwiritsidwa ntchito popanga masamba a turbine, zigawo za injini ndi zigawo zina zofunika kwambiri pa ndege ndi zombo zamlengalenga. Kusungunula ma alloy otentha kwambiri monga Inconel ndi Hastelloy kumafuna kuwongolera bwino njira zosungunula ndi kulimbitsa komanso kuchotsa zinyalala. Ma uvuni oyambitsa vacuum amapereka zofunikira pakusungunula ma alloy otentha kwambiri kuti apange zipangizo zapamwamba komanso zogwira ntchito bwino kwambiri zogwiritsira ntchito ndege.

Mu makampani opanga magalimoto, aluminiyamu imagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zake zopepuka komanso zosagwira dzimbiri. Kusungunula aluminiyamu kumafuna kuwongolera mosamala njira zosungunula ndi kuponyera kuti zitsimikizire kuti mphamvu zomwe makina amafunikira zakwaniritsidwa. Zitofu zotulutsira mpweya zimapereka mphamvu yowongolera kutentha ndi mpweya wofunikira kuti zisungunule aluminiyamu, zomwe ndizofunikira kwambiri popanga zipangizo zamagalimoto zapamwamba.

Mu makampani azachipatala, zinthu zosakanikirana ndi zinthu zachilengedwe monga titanium alloys ndi cobalt-chromium alloys zimagwiritsidwa ntchito popanga zinthu zoyikidwa m'mafakitale ndi zipangizo zachipatala. Kusungunula zinthuzi kumafuna kuyera kwambiri komanso kuwongolera kapangidwe kake kuti zitsimikizire kuti zikukwaniritsa zofunikira kwambiri pakugwirizana ndi zinthu zachilengedwe komanso mphamvu zamakina. Zofukizira zotsukira mpweya zimapereka zofunikira pakusungunula zinthu zosakanikirana ndi zinthu zachilengedwe, zomwe zimapangitsa kuti zikhale zofunika kwambiri popanga zipangizo zachipatala.

Mu makampani opanga zamagetsi, zitsulo zamkuwa zimagwiritsidwa ntchito chifukwa cha mphamvu zawo zamagetsi komanso kutentha. Kusungunula zitsulo zamkuwa kumafuna kuwongolera bwino kapangidwe kake ndi kuchotsa zinyalala kuti zitsimikizire kuti mphamvu zamagetsi ndi makina zikukwaniritsidwa. Zitofu zotulutsira mpweya wa vacuum zimapereka malo abwino osungunula zitsulo zamkuwa kuti apange zipangizo zapamwamba kwambiri zogwiritsira ntchito zamagetsi.

Mwachidule, ng'anjo zolowetsa mpweya m'malo osungira mpweya zimagwira ntchito yofunika kwambiri pakusungunula zitsulo zosiyanasiyana, chilichonse chili ndi zofunikira zake zapadera. Kuyambira chitsulo chosapanga dzimbiri mpaka titaniyamu, kuyambira zitsulo zotentha kwambiri mpaka zitsulo zotayidwa, kuyambira zitsulo zogwirizana ndi zinthu zachilengedwe mpaka zitsulo zotayidwa zamkuwa, ng'anjo zimenezi zimapereka zofunikira popanga zipangizo zapamwamba kwambiri m'mafakitale osiyanasiyana. Kuwongolera kutentha bwino, mlengalenga ndi chiyero chomwe chimapezeka kudzera mu kusungunula mpweya m'malo osungira mpweya ndizofunikira kwambiri pakukwaniritsa zofunikira zolimba za zitsulo zamakono. Pamene ukadaulo ukupitirira kupita patsogolo, ntchito ya ng'anjo zolowetsa mpweya m'malo osungira mpweya m'malo osungira mpweya idzakhala yofunika kwambiri pakukwaniritsa zosowa za mafakitale osiyanasiyana.
