Induction dumama saman hardening kayan aiki ne mafi yawa amfani ga zurfin dumama, ja punching, ƙirƙira, annealing, tempering, quenching da tempering, surface quenching, dumama da waldi na matsakaici diamita bututu, zafi taro, pinion quenching, da dai sauransu na kananan workpieces.

2) Hanyar dumama shigar mitar mitar mita

Mitar tana da ɗan girman mafi girma, kewayon mitar: sama da 200KHZ, har zuwa da dama na MHZ. Zurfin dumama da kauri sune mafi ƙanƙanta, kusan 0.1-1mm. An fi amfani da shi don quenching da waldi na gida ƙananan sassa ko sanduna na bakin ciki sosai, da kuma quenching na ƙananan kayan aiki.

A lokaci guda, waɗannan nau’ikan na’urorin dumama na’ura guda biyar suna da wasu fa’idodi. Duk suna amfani da IGBT induction dumama kayan wuta. Su ne mafi kyawun tanadin makamashi da kayan aikin dumama mahalli a cikin karni na 21st.

3) Hanyar dumama mitar sauti mai ƙarfi

Kewayon mitar: talakawa 20KHZ zuwa 40KHZ (saboda mitar sauti tana 20HZ zuwa 20KHZ, don haka ana kiranta super audio). Zurfin dumama da kauri suna kusan 2-3mm. Ana amfani dashi mafi yawa don dumama mai zurfi, annealing, tempering, quenching da tempering na workpieces tare da matsakaici diamita, dumama, waldi, thermal taro na bakin ciki-banga bututu da ya fi girma diamita, da kuma matsakaici gear quenching.

4) Hanyar dumama ƙarancin mitar induction

Matsakaicin mitar mafi ƙanƙanta, kewayon mitar: mitar wuta (50HZ) zuwa kusan 1KHZ, mitar da aka saba amfani da ita galibi mitar wuta ce. Zurfin dumama dangi shine mafi zurfi, kuma kauri mai dumama shine mafi girma, game da 10-20mm;. Yafi amfani da gaba ɗaya dumama, annealing, tempering da surface quenching na manyan workpieces. High mita waldi kayan aiki

5) Matsakaicin matsakaicin hanyar shigar da wutar lantarki: 1KHZ na yau da kullun zuwa 20KHZ, ƙimar dabi’a ta kusan 8KHZ. Zurfin dumama da kauri suna kusan 3-10mm. An fi amfani da shi don dumama, annealing, tempering, tempering da surface quenching na fi girma workpieces, manyan diamita shafts, manyan diamita lokacin farin ciki bango bututu, manyan modules gears, da ja naushi da kuma ƙirƙira na karami diamita sanduna.

Sabbin ƙarni na kayan aikin kashe mitoci masu ƙarfi suna haɓaka haɓakar samarwa sosai. Abubuwan da ake amfani da su sun fi bayyana a cikin abubuwa masu zuwa:

①Main fasali: ƙananan size, babban iko, sauri dumama, m core, low ikon amfani.

② Halayen kewayawa: Babban na’urar tana ɗaukar IGBT module, da’irar ba ta sarrafa cikakken gyaran gada, tacewa capacitor, inverter gada, jerin resonance fitarwa. Ya sha bamban da gaske da mitar ta zamani ta amfani da sautin layi daya na thyristor.

③ Halin ceton wutar lantarki: Idan aka kwatanta da tsohuwar zamani ta thyristor matsakaicin mitar, thyristor matsakaicin mitar dumama yana amfani da kusan digiri 470 a kowace ton na kayan aiki.

④ Ƙa’idar ceton wutar lantarki: Gyarawar da ba za a iya sarrafawa ba, kuma da’irar gyarawa tana da cikakkiyar gudanarwa. Babban fa’idar wutar lantarki, nau’in nau’in irin ƙarfin lantarki, da dai sauransu, ƙayyade ƙarfin ceton wannan kayan aikin.
