Mene ne bambanci tsakanin high mita quenching da matsakaicin mitar quenching?

Ka’idar aiki na babban mitar quenching da matsakaici-mita quenching iri ɗaya ne da na dumama dumama: wato, aikin aikin ana sanya shi a cikin inductor, kuma inductor gabaɗaya fataccen bututun jan ƙarfe ne mai shigar da matsakaicin mitar ko babban mitar canjin halin yanzu. (1000-300000Hz ko mafi girma). Madadin filin maganadisu yana haifar da halin yanzu na mitar guda ɗaya a cikin kayan aikin. Rarraba wannan induced halin yanzu a cikin workpiece ne m, yana da karfi a kan surface, amma sosai rauni a ciki, kuma yana kusa da 0 a tsakiyar. Ana amfani da wannan tasirin fata. , surface na workpiece za a iya mai tsanani da sauri, da surface zafin jiki yakan zuwa 800-1000 ℃ a cikin ‘yan seconds, da kuma yawan zafin jiki na core part ne kadan.

Duk da haka, a lokacin aikin dumama, rarraba abubuwan da aka haifar a cikin aikin aiki ba daidai ba ne, kuma tasirin dumama da aka samar ta hanyoyi daban-daban na yanzu ya bambanta. Sa’an nan, bambanci tsakanin babban mitar quenching da matsakaici-mita quenching ya zo:

1. Yawan kashewa

Mitar yanzu tsakanin 100 da 500 kHz

Layer mai taurin kai (1.5 ~ 2mm)

Abũbuwan amfãni bayan high mita quenching: high taurin, da workpiece ba sauki da za a oxidized, da nakasawa ne kananan, da quenching quality ne mai kyau, da kuma samar da yadda ya dace ne high.

Matsakaicin yawan mitoci ya dace da sassan da ke aiki a ƙarƙashin yanayi na jujjuyawar, kamar gabaɗaya ƙananan gears da shafts (kayan da ake amfani da su sune 45 # karfe, 40Cr)

2. Mutuwar tsaka -tsaki

Mitar na yanzu shine 500 ~ 10000 Hz

Layer mai tauri yana da zurfi (3 ~ 5mm)

Matsakaicin mitar quenching ya dace da sassan da ke jujjuyawa da nauyin matsa lamba, irin su crankshafts, manyan gears, dunƙulen injin niƙa, da sauransu (kayan da aka yi amfani da su sune 45 # karfe, 40Cr, 9Mn2V da ductile graphite.

A taƙaice, ɗayan bambance-bambancen da ke tsakanin babban mitar quenching da matsakaici-mita quenching shine bambancin kauri mai dumama. Matsakaicin maɗaukakiyar ƙima na iya taurare saman cikin ɗan gajeren lokaci, tsarin lu’ulu’u yana da kyau sosai, kuma ƙayyadaddun tsarin yana ƙarami. Ka kasance ƙarami.
