Isihloko: Ukubaluleka kweeFunu zokungeniswa kweFuna kwii-Smelting Alloys

Xa i-smelting alloys, inkqubo idinga ukuchaneka kunye nokulawula ukuqinisekisa ukuba iipropati ezifunwayo ziyafezekiswa. Inkalo ephambili yale nkqubo kukusetyenziswa kwesithando somlilo se-vacuum induction. Ezi ziko zidlala indima ebalulekileyo ekunyibilikiseni ingxubevange eyahlukeneyo, nganye ineemfuno zayo ezizodwa. Kule bhlog, siza kuphonononga iintlobo ezahlukeneyo ze-alloys ezifuna ukunyibilikiswa kwi-ai-vacuum induction ezikokunye nezizathu ezibangela imfuneko yabo.

Enye yezona zinto zixhaphakileyo zinyibilikiswa kusetyenziswa i-vacuum induction furnace yintsimbi engenasici. Insimbi engenasici i-alloy eguquguqukayo esetyenziselwa uluhlu olubanzi lwezicelo, ukusuka kwizixhobo zasekhitshini ukuya kumatshini woshishino. Inkqubo ye-smelting yensimbi engenasici idinga ulawulo oluchanekileyo lokubunjwa kwe-alloy kunye nokususwa kwezinto ezingcolileyo ezifana nekhabhoni kunye nesulfure. Iziko lokufunxa i-vacuum libonelela ngendawo efanelekileyo yokunyibilikisa isinyithi esingenasici kuba zinokulawula ngokuchanekileyo ubushushu kunye nomoya ngexesha lenkqubo yokunyibilikisa.

Enye i-alloy ebalulekileyo enyibilikisiweyo usebenzisa i-vacuum induction furnace yi-platinum-rhodium alloy. I-Platinam-rhodium alloy iyaziwa ngokuba namandla aphezulu-kubunzima bomlinganiselo kunye nokumelana nokubola, okwenza kube yinto ebalulekileyo kumashishini afana ne-aerospace kunye nezixhobo zonyango. Ukunyibilikisa i-platinum-rhodium alloy kufuna ukucoceka okuphezulu kuba ukungcola okuncinci kunokuchaphazela kakhulu iipropati zayo. I-vacuum induction furnaces iyakwazi ukudala imeko-bume ecocekileyo efunekayo ukunyibilikisa i-platinum-rhodium alloy, okwenza ukuba kubaluleke kakhulu ukuvelisa le ngxube exabisekileyo.

Kwishishini le-aerospace, ii-superalloys zikwimfuno ephezulu yokukwazi ukumelana nobushushu obugqithisileyo kunye noxinzelelo lomatshini. Ezi ngxubevange zisetyenziswa ekuveliseni iincakuba zeinjini yomoya, amacandelo eenjini kunye namanye amacandelo abalulekileyo kwinqwelo-moya nakwiziphekepheke. I-smelting high-temperature alloys ezifana ne-Inconel kunye ne-Hastelloy idinga ukulawulwa ngokuchanekileyo kweenkqubo zokunyibilika kunye nokuqina kunye nokususwa kokungcola. I-vacuum induction furnaces ibonelela ngeemeko eziyimfuneko zokunyibilikisa i-alloys yobushushu obuphezulu ukuvelisa izinto ezikumgangatho ophezulu, eziphezulu zokusebenza kwizicelo ze-aerospace.

Kwimizi-mveliso yeemoto, ii-alloys ze-aluminiyam zisetyenziswa ngokubanzi ngenxa yobunzima bazo kunye neempawu ezimelana ne-corrosion. Ukunyibilika kwe-aluminium alloys kufuna ukulawulwa ngokucokisekileyo kweenkqubo zokunyibilika kunye nokuphosa ukuze kuqinisekiswe ukuba izinto ezifunwayo zoomatshini ziyafezekiswa. Iziko lokungeniswa kwe-vacuum zibonelela ngolawulo oluchanekileyo lobushushu kunye nomoya ofunekayo ukunyibilikisa i-alloys ye-aluminium, ebaluleke kakhulu ekuveliseni izixhobo zemoto ezikumgangatho ophezulu.

Kwishishini lezonyango, ii-alloys ze-biocompatible ezifana ne-titanium alloys kunye ne-cobalt-chromium alloys zisetyenziselwa ukuveliswa kwezixhobo kunye nezixhobo zonyango. Ukunyibilika kwezi ngxubevange kufuna inqanaba eliphezulu lokucoceka kunye nolawulo lokubunjwa ukuze kuqinisekiswe ukuba ziyahlangabezana neemfuno ezingqongqo ze-biocompatibility kunye neempawu zoomatshini. I-vacuum induction furnaces ibonelela ngeemeko eziyimfuneko zokunyibilikisa i-alloys biocompatible, ezenza zibaluleke kakhulu kwimveliso yezixhobo zonyango.

Kwishishini le-elektroniki, ii-alloys zethusi zisetyenziselwa ukuhanjiswa kombane kunye neempawu ze-thermal. Ukunyibilikisa i-alloys zethusi kufuna ulawulo oluchanekileyo lokubunjwa kunye nokususwa kokungcola ukuqinisekisa ukuba izinto ezifunwayo zombane kunye nezomatshini ziyafezekiswa. Izixhobo zokwenziwa kwevacuum zibonelela ngendawo efanelekileyo yokunyibilikisa iialloyi zobhedu ukuvelisa izinto ezikumgangatho ophezulu wosetyenziso lwe-elektroniki.

Isishwankathelo, i-vacuum induction furnaces idlala indima ebalulekileyo ekunyibilikeni kwee-alloys ezahlukeneyo, nganye ineemfuno zayo ezizodwa. Ukusuka kwinsimbi engenasici ukuya kwi-titanium, ukusuka kwi-alloys ephezulu yokushisa ukuya kwi-alloys ye-aluminium, ukusuka kwi-alloys ye-biocompatible ukuya kwii-alloys zobhedu, ezi ziko zibonelela ngeemeko eziyimfuneko zokuveliswa kwezinto eziphezulu kumashishini ahlukeneyo. Ulawulo oluchanekileyo lobushushu, umoya kunye nobunyulu obuphunyezwe ngokunyibilika kwevacuum induction kubalulekile ukuhlangabezana neemfuno ezingqongqo zeealloys zale mihla. Njengoko itekhnoloji iqhubeka nokuhambela phambili, indima ye-vacuum induction furnaces kwi-alloy smelting iya kuba baluleke ngakumbi ekufezekiseni iimfuno zamashishini ahlukeneyo.
