GCr15 yotentha yozungulira zitsulo zozungulira

GCr15 ndi chitsulo wamba chomwe chimagwiritsidwa ntchito kupanga mipira ndi mphete zonyamulira. Zogulitsazo zimakhala ndi mawonekedwe a yunifolomu-mankhwala, kuchuluka kochepa kwa zinthu zovulaza, kuyera kwakukulu, carbide yogawidwa bwino, yabwino pamwamba. Ilinso ndi mawonekedwe a kukula kwakukulu kwa pulasitiki, mtundu wokhazikika wamankhwala otenthetsera, yunifolomu, ndi kuuma kwakukulu, kukana kwamphamvu kwambiri, kutopa kwakukulu. Ili ndi makina abwino kwambiri pambuyo pa spheroidize annealing. GB GCr15 yokhala ndi zitsulo ndi GB yokhazikika Aloyi Yonyamula zitsulo, Ndi yamtundu wapamwamba kwambiri wa carbon, aloyi chromium, chitsulo cha manganese. GB GCr15 katundu ndi chromium, manganese aloyi chitsulo specifications. GCr15 ndi yofanana ndi AISI 52100, DIN 100Cr6. Mapulogalamu ambiri amatha kusinthana.

Mechanical Properties

Makina amakina a zitsulo zokhala ndi GB GCr15 (zofanana ndi zitsulo) zafotokozedwa patebulo ili pansipa:

Kutentha mankhwala Zogwirizana

• Kuwonjezera chitsulo cha GCr15 Alloy

Pang'onopang'ono kutentha kwa 790-810 ℃ ndikulola nthawi zokwanira, lolani chitsulo chizitenthedwa bwino, Kenako kuziziritsa pang'onopang'ono mu ng'anjo. Njira zosiyanasiyana zomangirira zidzapeza kuuma kosiyana.Chitsulo chokhala ndi GCr15 chidzapeza Kulimba MAX 248 HB (kuuma kwa Brinell).

• Kuzimitsa ndi kutentha kwa GCr15 Aloyi yokhala ndi chitsulo

Kutenthetsa pang'onopang'ono mpaka 860 ° C, Kenako kuzimitsa ndi mafuta kupeza 62 mpaka 66 HRc kuuma. Kutentha kwakukulu kwa kutentha: 650-700 ℃, ozizira mumlengalenga, kupeza kuuma 22 mpaka 30HRC. Kutentha kutsika: 150-170 ℃, Kozizira  mu ari, pezani kulimba kwa 61-66HRC.

• Ntchito yotentha komanso yozizira ya GCr15 Alloy yokhala ndi chitsulo

Chitsulo cha GB GCr15 chikhoza kutentha kugwira ntchito pa 205 mpaka 538°C, GCr15 Bearing steel ikhoza kuzizira ntchito pogwiritsa ntchito njira wamba m'mikhalidwe yokhazikika kapena yokhazikika.

Mapulogalamu

Chitsulo cha GB GCr15 chimagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito pamakina ozungulira. Ntchito zofananira monga matupi a valve, mapampu ndi zolumikizira, kuchuluka kwa magudumu, mabawuti, mabawuti amitu iwiri, magiya, injini yoyaka mkati. Ma locomotives amagetsi, zida zamakina, mathirakitala, zida zogubuduza zitsulo, makina otopetsa, galimoto yanjanji, ndi shaft yotumizira makina amigodi pa mpira wachitsulo, wodzigudubuza ndi manja a shaft, etc.
