Ubwino wozimitsa ndi chiyani zida zotseketsa pafupipafupi lokha?

1. Pamwamba pa workpiece si kophweka kuti oxidized. Chifukwa cha kutentha, workpiece imakhudzidwa mosavuta ndi okosijeni, ndipo pamwamba pake ndi oxidized, zomwe zidzakhudza kutentha kwa workpiece. M’malo mwake, kuzimitsa kwafupipafupi sikungoyambitsa makutidwe ndi okosijeni ochulukirapo, komanso kuthamanga kwa kutentha kwa workpiece kumakhala kofulumira, komwe kumapangitsa kuti ntchitoyo ikhale yabwino, ndipo chogwirira ntchitocho sichimapunduka kawirikawiri.

2. Muyezo wa pamwamba oumitsa wosanjikiza wa mkulu-pafupipafupi kuzimitsidwa workpiece ndi mkati 1-1.5mm, amene ndi osiyana ndi wapakatikati pafupipafupi quenching. Kuzama kwa wosanjikiza wowumitsidwa wapakati pafupipafupi kuzimitsa kumatha kufikira mkati mwa 1-5mm, chifukwa chake kuzimitsa kwapakatikati kumagwiritsidwa ntchito ngati kuzimitsa kwanthawi yayitali sikungakwaniritse zofunikira. Zachidziwikire, ngati ndi zida zina zolimba zolimba, timagwiritsa ntchito njira yozimitsa ma frequency amphamvu.

3. Njira yowotchera ya zida ndi yotentha yosalumikizana, yomwe imatha kutenthetsa ntchitoyo mwachangu ndi deformation yachiwiri.

4. Njira yozimitsira ya workpiece ikhoza kuyendetsedwa yokha, ndipo ikhoza kugwirizanitsidwa ndi zida zamakina zozimitsa kuti zikwaniritse kuzimitsidwa kosalekeza, kuzimitsa gawo ndi kusanthula. Njira imeneyi ndi yabwino kwambiri kwa ma workpieces omwe ali ndi zofunika kwambiri.

5. Njira yopangira kutentha kwa zipangizo zozimitsira kutentha kwambiri ndizosavuta komanso zotsika mtengo.
