Njira yopewera mapindikidwe a ng’anjo yamagetsi yoyesera kutentha mankhwala ndi kuzimitsa

1. Kuwongolera mosamalitsa ubwino wa zipangizo zopangira, ndikuwongolera mosamalitsa zolakwika monga kulekanitsa kotayirira muzitsulo, ngati band-like, net-like and carbide liquefaction, ndi inclusions.

2. Sinthani kukula ndi kugawa kwa ma carbides mu kapangidwe ka annealed.

3. Pre-shaping ndi kupsinjika maganizo annealing pamaso kuzimitsa. Kupindika kotsalira kwa kutembenuka ndi kupsinjika kotsalira kwa kutembenuka kumakhala ndi chikoka chachikulu pakusintha kozimitsa. Pazinthu zolondola komanso zokhala ndi mipanda yopyapyala, zooneka movutikira, ziyenera kukonzedwanso pasadakhale ndikuyika kupsinjika kwa 450-670 ℃.

4. Pewani kutentha kwambiri. Pankhani yopeza dongosolo loyenera ndi kuuma, siziyenera kutsindika kwambiri kuti muwonjezere ndende ya alloying ndikuwonjezera kutentha kozimitsa. Pazinthu zoyambira bwino (monga zokhazikika kapena kuzimitsidwa kwachiwiri), kutentha kozimitsa kuyenera kuchepetsedwa momwe kuli koyenera.

5. Kutentha kozimitsa kuyenera kukhala kocheperako komanso kofanana. Pachifukwa ichi, zigawozo ziyenera kuyikidwa mofanana mu malo a isothermal mu ng’anjo, osati pafupi kwambiri ndi kutentha kwa thupi. Warping ndi extrusion ayenera kupewa; ngati n’koyenera, akhoza preheated pa 400℃ 500 ℃ pamaso Kutentha kupewa kutenthedwa ndi kutentha mosiyanasiyana.

6. Pewani kuzizira kwambiri. Pachifukwa ichi, malo ozizirirapo ayenera kusankhidwa moyenera ndipo kutentha kwa chipangizo chowongolera kuyenera kuyendetsedwa bwino. Ngati sikutsika kuposa kuzizira koopsa, yesetsani kuchepetsa kuzizira, makamaka pamene kuli pansi pa 450 ° C, kuyenera kuziziritsidwa pang’onopang’ono. Pakuti mosavuta deformable mbali, monga woonda-mipanda ferrules ndi diameters lalikulu. Atha kusankha kugwiritsa ntchito graded mafuta quenching kapena nitrate austempering.

7. Yesetsani kuziziritsa yunifolomu. Pamene kuzimitsa ndi kuzirala, m`pofunika kuganizira yunifolomu kuzirala mbali zonse za gawo. Gwiritsani ntchito mpweya woponderezedwa kapena makina osonkhezera ndi njira zina zoziziritsira. Posankha makina owumitsa makina ozungulira, kuthamanga kosiyanasiyana kuyenera kugwiritsidwa ntchito molingana ndi kukula kwa ferrule.

8. Pewani kugunda kwamakina kwa magawo. Pewani kugundana panthawi ya mayendedwe, kuyika ng’anjo, kutentha, ndi kuzizira, makamaka pakatentha kwambiri. Monga: Kuwotcha mu ng’anjo yamagetsi yoyesera, samalani ndi mapindikidwe a zigawozo mukamagwiritsa ntchito chipangizocho.
