Mkulu pafupipafupi kutentha mankhwala ndondomeko zosapanga dzimbiri zitsulo mipeni kukhitchini kuzimitsidwa ndi zida zotseketsa kwambiri

Zida za mpeni wa khitchini wosapanga dzimbiri ndi 3Cr13 kapena 4Cr13, ndipo mawonekedwe akunja ndi 180mmX80mmX2.5mm. Pambuyo pogaya movutikira mpaka 0.8-0.9mm, m’mphepete mwake mumayikidwa kuti muzitha kuzimitsa kutentha mung’anjo yozimitsa kwambiri. Pambuyo pozimitsa, imakwaniritsa zofunikira izi: kuuma 50-56HRC, malo olimba ≥25mm, kugawa kwa yunifolomu, ndi kusinthika ≤2mm.

1) Magawo amagetsi a chipangizocho. Mphamvu yolowera ndi 380V, voteji ya anode ndi 7.5kV, anode pano ndi 2.5A, voteji ya thanki ndi 5kV, grid pano ndi 0.6A, ndipo ma frequency ndi 250kHz.

2) Kuzimitsa Kutentha ndondomeko. Mng’anjo yozimitsa kwambiri imagwiritsidwa ntchito kuzimitsa. Inductor yapadera iyenera kupangidwa. Mpeni wakukhitchini uyenera kuyikidwa pamalo abwino mu inductor. Kuthamanga kwa kutentha kwa induction nthawi zambiri kumakhala 200-400 ℃ / s. Austenitization imatsirizidwa nthawi yomweyo, ndipo palibe kuteteza kutentha kumafunika. . Kutentha kozimitsa ndi 1050-1100 ℃, ndipo choziziritsa ndi mafuta. Kutentha kwa 200-220 ℃.

M’kati mwa 180mm X25mm m’dera lowumitsidwa, kuuma pambuyo pozimitsa ndi kutentha ndi> 50HRC, ndipo kuuma kwake kumakhala kofanana. Zizindikiro zonse zimatha kukwaniritsa zofunikira zaukadaulo.
