Yiziphi izinzuzo zokusebenzisa isithando somlilo esincibilikisa ivacuum kuma-alloys ensimbi ayigugu?

Isihloko: Izinzuzo zokusebenzisa isithando somlilo esincibilikisa ivacuum ukuze kuncibilike ingxubevange yensimbi eyigugu

Ziningi izinzuzo zokusebenzisa iziko lokuncibilika kwe-vacuum induction melting (VIM) lapho ukhiqiza ama-alloys ensimbi ayigugu. Lobu buchwepheshe obuthuthukisiwe buhlinzeka ngendawo elawulwayo yokuncibilika nokucwengisiswa kwezinsimbi eziyigugu, ukukhiqiza ama-alloys e-premium anezici ezithuthukisiwe. Kule bhulogi, sizohlola izinzuzo zokusebenzisa isithando somlilo esincibilikisa i-vacuum ukuze sikhiqize ama-alloys ensimbi ayigugu nokuthi singasiza kanjani ukukhiqiza izinto ezisebenza kahle kakhulu.

Enye yezinzuzo eziyinhloko zokusebenzisa ukuncibilika kwe-vacuum induction of alloys ensimbi eyigugu yikhono lokufeza ubumsulwa obuphezulu. Imvelo ye-vacuum ivimbela ukungcoliswa kwamagesi nokungcola, okuholela ekuhlanzekeni kwamakhemikhali okuhle kakhulu kwe-alloy. Lokhu kuhlanzeka kubalulekile ekusetshenzisweni kwezimboni ezifana ne-aerospace, yezokwelapha kanye nobucwebe, lapho ikhwalithi nobuqotho be-alloys yensimbi eyigugu ibalulekile. Ukwengeza, isimo esilawulwayo sesithando somlilo se-VIM sivumela ukwakheka kwe-alloy okunembayo, okuqinisekisa ukuvumelana komkhiqizo wokugcina nokuthembeka.

Ngaphezu kwalokho, ukusetshenziswa kwe-vacuum induction melting furnaces kuvumela ukukhiqizwa kwama-alloys afanayo kanye nama-alloys ahlakazeke kahle. Ukusatshalaliswa okufanayo kwezakhi zokuxuba kuyo yonke insimbi encibilikisiwe kubalulekile ukuze kuzuzwe izakhiwo ezifiselekayo zemishini namakhemikhali zomkhiqizo wokugcina. Inqubo ye-VIM yenza kube lula ukuxubana okuphelele kwezingxenye ze-alloy, okuholela ku-microstructure engenakho ukuhlukaniswa kanye nokukhubazeka. Lokhu kulawulwa kokwakheka kwe-alloy kanye ne-microstructure kusiza ukukhiqiza amandla aphezulu, ukumelana nokugqwala kanye nama-alloys ensimbi ayigugu aqinile.

Ngaphezu kwekhwalithi ephakeme yama-alloys akhiqizwayo, ukusebenzisa isithando somlilo esincibilikisa i-vacuum induction kwenza inqubo yokukhiqiza isebenze kahle futhi ingabizi. Ukulawula okunembayo kwezimo zokuncibilika nokucwengisiswa kunciphisa ukumosheka kwezinto kanye nokusetshenziswa kwamandla. Ubuchwepheshe be-VIM buphinde bunike amandla amazinga okuncibilika okusheshayo nawokuqiniswa, okwandisa ukukhiqiza futhi kunciphise isikhathi sokucubungula. Ngenxa yalokho, abakhiqizi bangakwazi ukuthuthukisa izinqubo zabo zokukhiqiza futhi banciphise izindleko zokusebenza ngenkathi beletha ama-alloys ensimbi ayigugu asebenza kahle ukuze ahlangabezane nezidingo zezimboni ezihlukahlukene.

Enye inzuzo yokusebenzisa ukuncibilika kwe-vacuum induction yama-alloys ensimbi eyigugu yikhono lokuhlanganisa ukwakheka okubanzi kwe-alloy kanye namazinga okushisa ancibilikayo. Kungakhathaliseki ukuthi igolide, isiliva, iplatinamu noma ezinye izinsimbi eziyigugu, ubuchwepheshe be-VIM bungaphatha izakhi ezihlukahlukene ze-alloying futhi bufinyelele iphuzu lokuncibilika elidingekayo. Lokhu kuvumelana nezimo kuvumela ukukhiqizwa kwama-alloys angokwezifiso enzelwe izinhlelo zokusebenza ezithile, okuhlinzeka abakhiqizi ngokuhlukahluka ukuze bahlangabezane nezidingo zemakethe ezahlukene. Kungakhathaliseki ukuthi izimila zezokwelapha, izingxenye ze-elekthronikhi noma ubucwebe bokunethezeka, i-VIM Furnaces inganikeza ama-alloys anezakhiwo ezenziwe ngokwezifiso ukuhlangabezana nezidingo eziqinile zezimboni ezahlukene.

Ukwengeza, ukusetshenziswa kweziko lokuncibilika kwe-vacuum induction kunomthelela ekusimameni kwemvelo ngokunciphisa ukukhishwa kwezinto ezikhishwayo kanye nokuphehla imfucuza. Isistimu yobuchwepheshe be-VIM evala iluphu ivimbela amagesi ayingozi kanye nezinhlayiya ukuthi zingakhishelwa emkhathini ngesikhathi sokuncibilika nokucwengisiswa. Ukwengeza, ukusetshenziswa kahle kwamandla nezinto zokusetshenziswa ezithandweni ze-VIM kuhambisana nezindlela zokukhiqiza ezisimeme futhi kunciphisa indawo ezungezile yokukhiqizwa kwensimbi eyigugu. Njengoba ukugxila komhlaba wonke ekuzinzeni nasekukhiqizeni okunomthwalo wemfanelo kuqhubeka kukhula, ubuchwepheshe be-VIM bunikeza isisombululo esisebenzayo esihlangabezana nezidingo zemboni ngenkathi kunciphisa umthelela wemvelo.

Kafushane, izinzuzo zokusebenzisa isithando somlilo esincibilikisa i-vacuum induction ukuncibilikisa ingxubevange yensimbi eyigugu ayinakuphikwa. Kusukela ekuzuzeni ubumsulwa nokufana okuphezulu kuya ekuthuthukiseni ukusebenza kahle nokusimama, ubuchwepheshe be-VIM budlala indima ebalulekile ekukhiqizeni ama-alloys asebenza kahle kakhulu ezinhlobonhlobo zezinhlelo zokusebenza. Njengoba izimboni ziqhubeka nokufuna ikhwalithi ephakeme kanye nezakhiwo ezenziwe ngokwezifiso kuma-alloys ensimbi ayigugu, izithando ze-VIM ziyisixazululo esinokwethenjelwa nesithuthukisiwe sokuhlangabezana nalezi zidingo. Ubuchwepheshe be-VIM buhlala buyisisekelo sokuqanjwa kabusha ekukhiqizeni ingxubevange yensimbi eyigugu ngenxa yekhono layo lokuletha ama-alloys asezingeni eliphezulu ngokungaguquki ngenkathi kunciphisa umthelela wemvelo.
