Yadda za a zabi induction dumama kayan aiki?

Induction dumama kayan aikin za a iya kusan kashi: Super mitar audio induction dumama kayan aiki, high mita shigar dumama kayan aiki, matsakaici mita shigar dumama kayan aiki, da dai sauransu bisa ga daban-daban fitarwa mitoci. Hanyoyin dumama daban-daban suna buƙatar mitoci daban-daban. Idan zaɓin mitar da ba daidai ba ba zai iya biyan buƙatun dumama ba, kamar jinkirin lokacin dumama, ƙarancin aikin aiki, dumama mara daidaituwa, da gazawar zazzabi don biyan buƙatun, yana da sauƙi don haifar da lalacewa ga kayan aikin.

Don zaɓar mitar daidai, da farko, dole ne mu fahimci buƙatun tsarin dumama na samfur. Gabaɗaya, akwai yanayi da yawa:

Workpieces ne diathermy, kamar fasteners, daidaitattun sassa, auto sassa, hardware kayan aikin, zafi upsetting da zafi mirgina drills, da dai sauransu Ya fi girma diamita na aikin yanki, da ƙananan mita ya zama. Dace da matsananci high mita (100-500KHZ) kasa φ4mm, φ4-16mm dace da high mita (50-100KHZ) φ16-40mm dace da super audio (10-50KHZ) sama φ40mm dace da matsakaici mita (0.5-10KHZ)

Maganin zafi, ramuka, gears, quenching da annealing na bakin karfe, da dai sauransu, dauki quenching a matsayin misali. The workpiece na bukatar shallower da quenching Layer, da mafi girma da mita ya zama, da kuma zurfin quenching Layer, da ƙananan mita ya kamata. Layer quenching shine: 0.2-0.8mm, dace da 100-250KHZ UHF 0-1.5mm, dace da 40-50KHZ babban mitar, super audio 1.5-2mm, dace da 20-25KHZ super audio 2.0-3.0mm, dace da 8 -20KHZ super audio, matsakaicin mitar 3.0 -5.0mm ya dace da 4-8KHZ matsakaicin mitar 5.0-8.0mm ya dace da mitar 2.5-4KHZ
