Njira Yochizira Kutentha kwa WCB Castings

WCB, chinthu choponyera chitsulo cha kaboni chofanana ndi ASTM A216 Gulu la WCB, imachita njira yochizira kutentha kuti ikwaniritse zofunikira zamakina, kukhazikika kwa mawonekedwe, komanso kukana kupsinjika kwamafuta. Pansipa pali kufotokozera mwatsatanetsatane za kayendedwe ka kutentha kwa WCBYD7A1X-16 Gulugufe Valvezojambula:

pa1. Kutenthetsapa

• paCholinga: Kuchepetsa kutentha kwa kutentha komanso kupewa ming'alu panthawi ya chithandizo cha kutentha kwambiri.
• paNjira: Ma castings amatenthedwa pang'onopang'ono mu ng'anjo yoyendetsedwa mpaka kutentha kosiyanasiyana300–400°C (572–752°F).
• paZofunika Kwambiri: Kutentha kwa kutentha kumasungidwa pa50–100°C/ola (90–180°F/ola)kuonetsetsa kugawidwa kwa kutentha kofanana.

pa2. Austenitizing (Normalizing)pa

• paCholinga: Kupanga homogenize microstructure, kuyenga kukula kwa tirigu, ndikusungunula ma carbides.
• paNjira:
• Ma castings amatenthedwa mpaka kutentha kwa austenitizing890–940°C (1634–1724°F).
• Kusungidwa pa kutentha uku kwaMaola 1-2 pa 25 mm (1 inchi) ya makulidwe a gawokuwonetsetsa kusintha kwathunthu.
• Utakhazikika mu mpweya wokhazikika (normalizing) mpaka kutentha.

pa3. Kutenthapa

• paCholinga: Kuchepetsa kupsinjika kotsalira, kukonza kulimba, komanso kukhazikika kwa microstructure.
• paNjira:
• Pambuyo pa normalizing, ma castings amatenthedwanso ku kutentha kwa kutentha kwa590–720°C (1094–1328°F).
• Anyowetsedwa ndi kutentha uku kwaMaola 1-2 pa 25 mm (1 inchi) ya makulidwe.
• Uziziritsidwa mu mpweya kapena ng'anjo-utakhazikika pamlingo wolamuliridwa kuti mupewe kupsinjika kwatsopano.

pa4. Kuyendera Pambuyo pa Chithandizopa

• paCholinga: Kutsimikizira kuti zikutsatira miyezo ya ASTM A216.
• paNjira:
• Kuyesa kwamakina (mwachitsanzo, kulimba kwamphamvu, kulimba kwa zokolola, kuuma).
• Kusanthula kwa Microstructural kuti muwonetsetse kufanana komanso kusapezeka kwa zolakwika.
• Dimensional cheke kuti atsimikizire kukhazikika kwamankhwala pambuyo pa kutentha.

paNjira Zosasankha (Zokhudza Nkhani)pa

• paKuchepetsa Kupsinjika: Kwa ma geometri ovuta, njira yowonjezera yochepetsera kupsinjika imatha kuchitika pa600–650°C (1112–1202°F)kuthetsa kupsinjika kotsalira kuchokera ku makina kapena kuwotcherera.
• paKuzizira Koyendetsedwa: Pazigawo zokhuthala, kuziziritsa pang'onopang'ono (monga kuziziritsa m'ng'anjo) kungagwiritsidwe ntchito panthawi yotentha kuti kukhale kosavuta.

paMfundo zazikuluzikulupa

• paFurnace Atmosphere: Kusalowerera ndale kapena pang'ono oxidizing mpweya kuteteza decarburization.
• paKutentha Uniformity: ± 10 ° C kulolerana kuti muwonetsetse zotsatira zofananira.
• paZolemba: Kutsatiridwa kwathunthu kwa magawo ochizira kutentha (nthawi, kutentha, mitengo yozizirira) kuti mutsimikizire mtundu.
