Momwe mungawonetsere zofunikira pamtundu wa Induction Kutentha zida

1. Zigawo zomveka zokhululukirira mapangidwe ndi zofunikira za chithandizo cha kutentha chisanadze

Mapangidwe a gawolo ayenera kukhala oyenera kutengera kutentha kwa induction, ndipo mawonekedwe ake azikhala osavuta kupeza kutentha kofanana. Ziyenera kukwaniritsa zofunikira zaukadaulo pakuwongolera kutentha kwa induction, magawowo amafunikira kutenthedwa, ndipo magawo omwe amafunikira kukana kuvala bwino nthawi zambiri amakhala abwinobwino; mbali kapena mbali zopyapyala zomwe zimafuna mphamvu zambiri komanso kukana kuvala kwambiri nthawi zambiri zimazimitsidwa komanso kupsa mtima. .

2. Kusankhidwa koyenera kwa magawo ndi zida, dongosolo loyenera la njira zopangira

Ndikoyenera kugwiritsa ntchito chitsulo chosakanizidwa bwino ngati chinthu chopangira zida zotenthetsera kutentha. Zigawo zapadera zimafunanso kusankhidwa kwa carbon zomwe zili muzitsulo. Zitsulo zomwe zimagwiritsidwa ntchito nthawi zambiri ndi: 35, 40, 45, 50, ZG310-570, 40Cr, 45Cr35rMo, 42CrMo, 40MnB ndi 45MnB, etc.

Zitsulo zoponyedwa zomwe zimagwiritsidwa ntchito nthawi zambiri ndi monga: chitsulo choponyera ductile, chitsulo chosungunuka, chitsulo chosungunula imvi ndi chitsulo cha alloy cast.

Zomwe zili ndi pearlite (gawo la voliyumu) ​​la chitsulo cha nodular cast for induction heat treatment tikulimbikitsidwa kukhala 75% kapena kuposa. Ndizoyenera kwambiri kuti pearlite (gawo la voliyumu) ​​likhale lalikulu kuposa 85%, ndipo mawonekedwe a pearlite makamaka ndi flake; chitsulo chosungunuka chimafuna kufananitsa kwa graphite Kuwaza bwino ndikugawa mofanana.

3. Zofunikira pazigawo musanazimitse

(1) Zida za zigawozo zimakwaniritsa malamulo opangira.

(2) Pamwamba pa zigawozo ndi zoyera komanso zopanda mafuta ndi chitsulo.

(3) Palibe chilema monga mabampu, ming’alu, corrosion, ndi oxide scale pamwamba pa zigawozo.

(4) Kuthamanga kwaukali kwa gawo lozimitsidwa pamwamba pa gawolo kuyenera kukhala kofanana kapena kuposa Ra6.3μm, sikuyenera kukhala wosanjikiza decarburization, burrs, kuphwanya, etc. saloledwa.

(5) Ziwalozo zakhala zikuyenda bwino komanso kuzimitsa ndi kutentha pasadakhale malinga ndi ndondomeko ya ndondomeko, ndipo kuuma kumakwaniritsa zofunikira. Kukula kwa njere kwa kapangidwe ka metallographic kuyenera kukhala 5-8.

(6) Miyeso ya geometric ya zigawozo zimakwaniritsa zofunikira za ndondomekoyi, ndipo palibe njira zomwe zikusowa kapena zowonjezereka.
