Mphete yopangira iyi imaphatikizapo zopangira monga mphete yapakati, mphete ya fan, mphete yaying'ono yosindikizira, ndi mphete yamagetsi ya tanki yamadzi ya turbine jenereta yamagetsi, koma siyoyenera kupangira mphete zopanda maginito.
Njira yopanga:
1 Kusungunula
1.1. Chitsulo chomwe chimagwiritsidwa ntchito popanga zitsulo chiyenera kusungunuka mu ng'anjo yamagetsi ya alkaline. Ndi chilolezo cha wogula, njira zina zosungunulira monga electro-slag remelting (ESR) zingagwiritsidwenso ntchito.
1.2. Pazojambula za giredi 4 kapena kupitilira apo ndi zopangira za giredi 3 zokhala ndi khoma kupitirira 63.5mm, chitsulo chosungunula chogwiritsidwa ntchito chiyenera kutsukidwa kapena kuyengedwa ndi njira zina kuchotsa mpweya woipa, makamaka haidrojeni.
2 Kupanga
2.1. Ingot iliyonse yachitsulo iyenera kukhala ndi ndalama zokwanira zodulira kuti zitsimikizire kuti zili bwino.
2.2. Zopangira zitsulo ziyenera kupangidwa pa makina osindikizira, nyundo zopangira, kapena mphero zokhala ndi mphamvu zokwanira kuti zitsimikizidwe kuti zimapangidwira gawo lonse lachitsulo ndi kuonetsetsa kuti gawo lililonse lili ndi chiŵerengero chokwanira chopangira.
3 Chithandizo cha kutentha
3.1. Pambuyo forging anamaliza, forgings ayenera yomweyo pansi preheating mankhwala, amene angakhale annealing kapena normalizing.
3.2. The ntchito kutentha mankhwala kuzimitsa ndi kutentha (16Mn angagwiritse ntchito normalizing ndi kutentha). Kutentha komaliza kwa ma forgings sikuyenera kutsika kuposa 560 ℃.
4 Chemical kapangidwe
4.1. Kusanthula kapangidwe ka mankhwala kuyenera kuchitidwa pagulu lililonse lachitsulo chosungunuka, ndipo zotsatira zowunikira ziyenera kutsata miyezo yoyenera.
4.2. Kusanthula kwa mankhwala omalizidwa kumayenera kuchitidwa pakupanga kulikonse, ndipo zotsatira zake ziyenera kutsata miyezo yoyenera. 4.3. Pamene vacuum decarburizing, zomwe zili pa silicon siziyenera kupitirira 0.10%. 4.4. Pazopanga mphete za giredi 3 zokhala ndi makulidwe opitilira 63.5mm, zida zokhala ndi faifi tambala kuposa 0.85% ziyenera kusankhidwa.
5 Makina katundu
5.1. Ma tangential mechanical of the forgings ayenera kutsata miyezo yoyenera.
6 Kuyesa kosawononga
6.1. Zolembazo zisakhale ndi ming'alu, zipsera, zopindika, mabowo ochepera, kapena zolakwika zina zosaloledwa.
6.2. Pambuyo pakukonza molondola, malo onse ayenera kuyang'aniridwa ndi maginito. Kutalika kwa mzere wa maginito sikuyenera kupitirira 2mm.
6.3. Pambuyo ntchito kutentha mankhwala, forgings ayenera kuyesedwa akupanga kuyezetsa. Kukhudzika koyambirira kofananako kuyenera kukhala φ2 mm, ndipo cholakwika chimodzi sichiyenera kupitilira m'mimba mwake φ4mm. Pachilema chimodzi pakati pa ma diameter ofanana a φ2mm~¢ 4mm, payenera kukhala zolakwika zosaposa zisanu ndi ziwiri, koma mtunda wapakati pa zolakwika ziwiri zoyandikana uyenera kukhala wokulirapo kuwirikiza kasanu kuchuluka kwa chilemacho, ndipo kuchepetsedwa kwapang'onopang'ono chifukwa cha zolakwika sikuyenera kukhala. kuposa 6dB. Zolakwika zomwe zimaposa zomwe zili pamwambazi ziyenera kufotokozedwa kwa kasitomala, ndipo onse awiri ayenera kukambirana za momwe angagwiritsire ntchito.
