Izindaba

Sekungamakhulu eminyaka igolide lithakazelisa isintu, hhayi nje ngenxa yokubaluleka kwalo okungaphakathi, kodwa nangenxa yokucwebezela kwalo okumangalisayo nokucwebezela kwalo. Noma ngabe ubucwebe, izinhlamvu zemali noma ukusetshenziswa kwezimboni, ubuhlakani begolide bufakazela izici zalo ezihlukile. Nokho, ukuthola ukukhanya okuphelele kudinga okungaphezu kokupholisha; Ngokuvamile kuhilela izinqubo ezithuthukisiwe ze-metallurgical.I-Induction Melting Furnace(VIM) ingenye yenqubo enjalo edlala indima ebalulekile ekucwengeni igolide, ithuthukise izimfanelo zayo zobuhle nokusebenza kwayo. Kulesi sihloko, sizobheka indlela yokwenza igolide licwebezele, kanye nendima ebalulekileI-Induction Melting Furnaceidlala kunqubo.

Funda ngegolide nezakhiwo zalo

Igolide liyinsimbi eyigugu eyaziwa ngokumelana nokugqwala nokubola. Ukwakheka kwayo kwe-athomu kuyivumela ukuba ibonise ukukhanya kahle, inikeze ukubenyezela kwayo okuyisici. Nokho, ubumsulwa begolide bungahlukahluka, futhi ukungcola kungenza buthaka ukucwebezela kwalo. Igolide elimsulwa (okungukuthi 24 karat gold) lithambile futhi liyathandeka, okulenza lingalungeli ukusetshenziswa kwansuku zonke ubucwebe. Ngakho-ke, igolide livame ukuxutshwa nezinye izinsimbi ezifana nethusi, isiliva, noma i-palladium ukuze lithuthukise ukuqina kwalo kuyilapho ligcina ukucwebezela kwalo.

Ukubaluleka Kokuhlanzeka Kwegolide

Ukucwebezela kwegolide kuhlobene ngokuqondile nobumsulwa balo. Ukungcola akuthinti kuphela umbala nokucwebezela kwegolide, kodwa futhi nekhwalithi yayo yonke. Ngokwesibonelo, ukuba khona kwethusi kungenza igolide libe nombala obomvu, kuyilapho isiliva lingenza libe nombala omhlophe. Ukuze bathole umbala ofunekayo nokucwebezela, abakhandi begolide ngokuvamile bafuna ukucwenga igolide libe msulwa ngezinga eliphakeme. Lapha kulaphoI-Induction Melting Furnacekungene ukudlala.

YiniI-Induction Melting Furnace?

I-Induction Melting Furnace(VIM) inqubo ye-metallurgical eyinkimbinkimbi esetshenziselwa ukuncibilikisa kanye nokucwenga izinsimbi endaweni elawulwayo. Inqubo ihlanganisa ukubeka insimbi ku-crucible nokuyishisisa kusetshenziswa ikhoyili yokungeniswa. Wonke umsebenzi wenziwa ku-vacuum chamber, evimbela ukungcoliswa komoya futhi inciphise ukugcwala kwe-oxidation. Le ndlela inenzuzo ngokukhethekile ezinsimbini eziyigugu njengegolide, njengoba ivumela ukulawulwa okunembile kwenqubo yokuncibilika kanye nokwakheka komkhiqizo wokugcina.

I-Induction Melting Furnaceinqubo

Ukulungiselela: Isinyathelo sokuqala ku-VIM ukulungisa igolide nanoma yiziphi izinsimbi ze-alloy. Izinto ezisetshenziswayo zikalwa ngokucophelela futhi zihlanzwe ukuze kukhishwe noma yikuphi ukungcola okungaphezulu.

Iyancibilika: Faka insimbi elungisiwe ku-crucible bese uyibeka ngaphakathi kwekhoyili yokungeniswa. Ukushisa kokungeniswa kwakha inkambu ye-electromagnetic encibilikisa insimbi ngokushesha nangokulinganayo.

Vacuum Environment: Amakamelo e-vacuum adalwe ukuze asuse umoya namanye amagesi angase asabele ngensimbi encibilikisiwe. Le ndawo ibalulekile ekugcineni ukuhlanzeka kwegolide nokuvimbela i-oxidation.

Ingxubevange: Uma igolide lizohlanganiswa nezinye izinsimbi, lokhu kwenziwa ngesikhathi sokuncibilika. Ukulawulwa okunembile kwezimo zokushisa nezimo ze-vacuum kuvumela ukuxutshwa okunembile kwezinsimbi, okuholela ku-alloy e-homogeneous.

Iyasakaza: Uma igolide selincibilikile futhi lifinyelela ekubunjweni okufunayo, lithelwa esikhunjeni ukuze lenze izingothi zegolide noma ezinye izimo. Inqubo yokupholisa nayo iyalawulwa ukuze kuqinisekiswe ubuqotho bomkhiqizo wokugcina.

Ukuqeda: Ngemva kokulingisa, igolide lingase lenze izinqubo ezengeziwe njengokuthungathwa, ukupholishwa, kanye ne-electroplating ukuze lithuthukise ukucwebezela kwalo futhi lilungiselele ubucwebe noma ezinye izinto ezisetshenziswayo.

Izinzuzo zokuncibilika kwegolide kwe-Vacuum Induction

1. Thuthukisa ubumsulwa

Enye yezinzuzo eziyinhloko ze-VIM yikhono layo lokukhiqiza igolide elihlanzekile. Indawo ye-vacuum inciphisa ubungozi bokungcola, iqinisekise ukuthi umkhiqizo wokugcina awunazo izinto ezingafuneki. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho ubumsulwa bubaluleke kakhulu, njengezinto zikagesi noma izisetshenziswa zezokwelapha.

2. Thuthukisa izakhiwo zemishini

Inqubo elawulwayo yokuncibilika nokupholisa ku-VIM ithuthukisa izakhiwo zegolide. Ngokuphatha ngokucophelela inqubo ye-alloying, abakhiqizi bangakha ama-alloys egolide anezici ezithile, njengamandla akhulayo noma i-ductility ethuthukisiwe, ngaphandle kokudela i-luster.

3. Izinga elizinzile

I-VIM inika amandla ukulawula okunembayo kwezinqubo zokuncibilika kanye ne-alloying, okuholela kukhwalithi engaguquki ukusuka kunqwaba kuye kwinqwaba. Lokhu kubalulekile kubakhiqizi abadinga ukungaguquguquki komkhiqizo, noma ngabe ubucwebe noma ukusetshenziswa kwezimboni.

4. Yehlisa i-oxidation

Imvelo ye-vacuum ye-VIM inciphisa kakhulu ingozi ye-oxidation phakathi nenqubo yokuncibilika. Lokhu kubaluleke kakhulu ngegolide, njengoba i-oxidation ingabangela ukushintsha kombala nokulahlekelwa ukucwebezela. Ngokunciphisa ukuthintana komoyampilo, i-VIM isiza ukugcina izimfanelo zobuhle zegolide.

5. Ukuguquguquka

I-VIM ayigcini nje ngegolide; ingasetshenziswa ukuncibilikisa kanye nokucwenga izinhlobonhlobo zezinsimbi. Lokhu kuguquguquka kwenza kube inketho ekhangayo kubakhiqizi abasebenza ngezinto ezihlukahlukene futhi badinga inqubo ethembekile yokuncibilika.

Indlela yokwenza igolide licwebezele

NgenkathiI-Induction Melting Furnaceidlala indima ebalulekile ekucwengeni igolide, izindlela ezihlukahlukene zokuqeda ziyadingeka ukuze kuzuzwe ukukhanya okuphelele. Nazi ezinye izindlela zokwenza igolide licwebezele:

1. Ukupholisha

Ukupholisha kungenye yezindlela ezivame kakhulu zokuthuthukisa ukukhanya kwegolide. Inqubo ihilela ukusebenzisa izinto ezilimazayo ukuze kususwe ukungapheleli kwendawo futhi kudale indawo ebushelelezi, ekhanyayo. Abenzi bobucwebe bavame ukusebenzisa amakhompiyutha okupholisha kanye namasondo aqhumayo ukuze bathole ukukhanya okuphezulu.

2. Ukuhlanza

Ngaphambi kokupholishwa, igolide kufanele lihlanzwe ukuze kukhishwe ukungcola, uwoyela noma ukonakala. Ungasebenzisa isisombululo esithambile samanzi afudumele nensipho ethambile, bese uhlanza futhi womise ngendwangu ethambile.

3.I-Electroplating

Kwezinye izinhlelo zokusebenza, ukufakwa kwegolide kungathuthukisa ukucwebezela nokubukeka kwezinto zegolide. Le nqubo ihilela ukumboza isisekelo sensimbi ngongqimba oluncane lwegolide, okunikeza isiphetho esicwebezelayo kuyilapho kunciphisa izindleko.

4. I-Rhodium Plating

I-Rhodium Plating iyindlela ethandwayo esetshenziselwa ukuthuthukisa ukucwebezela kwegolide elimhlophe. I-Rhodium iyinsimbi ecwebezelayo enikeza isiphetho esikhanyayo, njengesibuko. Le nqubo ayigcini nje ngokuthuthukisa ukukhanya kodwa futhi yengeza ungqimba lwesivikelo ngokumelene nokuklwebheka nokushintsha umbala.

5. Ukugcinwa njalo

Ukuze kugcinwe igolide licwebezela, ukunakekelwa njalo kubalulekile. Lokhu kuhlanganisa ukuhlanza nokupholisha njengoba kudingeka, kanye nokugcinwa okufanele kwezinto zegolide ukuvimbela imihuzuko nokulimala.

Ekuphetheni

Ukukhanga kwegolide akuxhomekile nje kuphela enanini lalo kodwa nasekubengezeni kwalo okumangalisayo. Ukufeza i-gloss ephelele kudinga inhlanganisela yokuhlanzeka okuphezulu kanye namasu okuqeda asebenzayo.I-Induction Melting Furnaceidlala indima ebalulekile ekucwengisweni kwegolide, iqinisekisa ukuthi ifinyelela ubumsulwa obudingekayo kanye namazinga ekhwalithi. Ngokuqonda ukubaluleka kwe-VIM nokusebenzisa amasu okunakekelwa okufanele, noma ubani angajabulela ukucwazimula kwegolide iminyaka ezayo. Kungakhathaliseki ukuthi kubucwebe, izinto zikagesi noma ezinye izinhlelo zokusebenza, ukucwebezela kwegolide bekulokhu kuwuphawu lobuhle nobuhle, obuzuzwa ngezinqubo ezithuthukisiwe zensimbi.
