Isihloko: Ukuqonda Ukubaluleka Kokuncibilikisa Izinsimbi Zensimbi Ku-Isithando Sokuncibilikisa Ukufakwa Kwe-Vacuum

Inqubo yokuncibilikisa idlala indima ebalulekile lapho kukhiqizwa ama-alloy ensimbi asezingeni eliphezulu. Ukuncibilikisa kuhilela ukukhipha izinsimbi kuma-ore nokudala ama-alloy ngokuhlanganisa izakhi ezahlukene zensimbi. Enye yezindlela ezithuthuke kakhulu zokuncibilikisa ama-alloy ensimbi ukusebenzisa ama-vacuum induction melting (VIM) furnaces. Lobu buchwepheshe obusha bunikeza izinzuzo eziningi, okwenza kube ithuluzi elibalulekile ekukhiqizweni kwama-alloy ensimbi ahlukahlukene.

Ngakho-ke, yiziphi izinhlobo zezinsimbi zensimbi ezidinga ukuncibilikiswa ku-isithando sokuncibilikisa i-vacuum inductionUkuze uphendule lo mbuzo, kubalulekile ukuqonda izici ezihlukile zesithando se-VIM kanye nezidingo ezithile zezinsimbi ezahlukene zensimbi.

Okokuqala, kubalulekile ukuqaphela ukubaluleka kokusebenza endaweni engenamoya lapho kuncibilikiswa izinsimbi ezithile zensimbi. Ukugcina igumbi le-vacuum lingenamoya kanye nokunye ukungcola kubalulekile ukuvimbela i-oxidation kanye nokungcola ngesikhathi senqubo yokuncibilikisa. Lokhu kubaluleke kakhulu kuma-alloy asabela kakhulu noma athambekele ekwakhekeni kwe-oxide lapho evezwa emoyeni.

Uhlobo olulodwa lwe-alloy yensimbi oluzuza ngokuncibilikiswa esithandweni sokuncibilikisa i-vacuum induction yi-alloy esezingeni eliphezulu. Lezi zinto ezithuthukisiwe zaziwa ngamandla azo akhethekile, ukumelana nokugqwala kanye nokusebenza kahle kwezinga lokushisa eliphezulu, okwenza zibe yinto ebalulekile ezimbonini ezifana nezindiza, ukukhiqizwa kwamandla kanye nokucubungula amakhemikhali. I-alloy esezingeni eliphezulu ivame ukuqukatha inhlanganisela ye-nickel, i-cobalt, insimbi nezinye izinto, futhi ukukhiqizwa kwazo kudinga ukulawulwa okunembile kwenqubo yokuncibilikisa ukuqinisekisa ukuthi izakhiwo zezinto ezifiselekayo ziyafezwa. Ngokusebenzisa isithando se-VIM, abakhiqizi bangasusa ukungcola ngempumelelo futhi balondoloze ubuqotho be-alloy, okuholela ezimpahleni ezinhle kakhulu zemishini nezokushisa.

Ngaphezu kwama-alloy okushisa okuphezulu, ezinye izinsimbi ezikhethekile zidinga ukusetshenziswa kwezitofu zokuncibilikisa i-vacuum induction ukuze zincibilike. Isibonelo, insimbi engagqwali yaziwa ngokumelana kwayo nokugqwala kanye nokufaka umbala, okwenza kube ukukhetha okuthandwayo kokusetshenziswa ezimbonini zokudla neziphuzo, zemithi kanye nezamakhemikhali. Ukuncibilikisa insimbi engagqwali endaweni evalekile kusiza ukunciphisa ukuba khona kokungcola okuyingozi njengesulfure ne-phosphorus, okungalimaza ukumelana nokugqwala kwezinto. Ngenxa yalokho, insimbi engagqwali eqediwe inobumsulwa obuphezulu kanye nokusebenza, ihlangabezana nezidingo eziqinile zezicelo ezahlukahlukene zezimboni.

Ngaphezu kwalokho, imikhakha yezindiza kanye nezokuvikela ithembele ekukhiqizweni kwama-alloy e-titanium, anikeza isilinganiso esihle kakhulu samandla nesisindo kanye nokumelana nokugqwala okuvelele. Ukuncibilikisa ama-alloy e-titanium ezithandweni zokuncibilikisa ze-vacuum induction kubalulekile ekufinyeleleni ubumsulwa obuphezulu kanye nokufana okudingekayo ezingxenyeni zezindiza njengezinjini zezindiza kanye nezinto zokwakha. Amandla okulawula ukwakheka kanye nesakhiwo esincane sama-alloy e-titanium ngokusebenzisa ubuchwepheshe be-VIM kuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezindinganiso zokusebenza eziqinile kanye nokuthembeka ezindaweni zezindiza ezidingakalayo.

Ngaphezu kwalezi zibonelo ezithile, ezinye izinhlobo eziningi zensimbi, okuhlanganisa izinsimbi zamathuluzi, izinsimbi ezisheshayo, kanye nezinsimbi ezisebenza ngogesi, zingazuza ekuqondeni nasekuhlanzekeni okunikezwa ukuncibilika kwesithando somlilo esincibilikiswa yi-vacuum induction. Amandla okulungisa inqubo yokuncibilikisa ukuze ivumelane nezidingo ezihlukile zengxube ngayinye avumela abakhiqizi ukuthi bakhiqize izinto ezinezici ezidingekayo zemishini, ezishisayo nezamakhemikhali ukuze kuhlangatshezwane nezidingo ezahlukahlukene zezimboni ezahlukene.

Ngamafuphi, ukuncibilikisa izinsimbi ezihlanganisiwe ezitsheni zokuncibilikisa i-vacuum induction kubalulekile ekufinyeleleni amazinga aphezulu okuhlanzeka, ukufana kanye nokulawula okudingekayo ezintweni ezithuthukisiwe. Kungakhathaliseki ukuthi kuyi-superalloys yezicelo zokushisa okukhulu, insimbi engagqwali yezingxenye ezingagqwali, noma i-titanium alloys yezindiza nezinhlelo zokuzivikela, amakhono obuchwepheshe be-VIM adlala indima ebalulekile ekuhlangabezaneni nezidingo eziqinile zemboni yanamuhla. Ngokuqonda ukubaluleka kokuncibilikisa endaweni engenamanzi kanye nezidingo ezithile zezinsimbi ezahlukene zensimbi, abakhiqizi bangasebenzisa ngokugcwele amandla ezitofu ze-VIM ukukhiqiza izinto ezisezingeni eliphezulu eziqhuba ukusungula izinto ezintsha kanye nentuthuko emikhakheni ehlukahlukene.
