Sand-Yokhazikika Kulanda Mphero Yanji
QT450-10
QT 450-10 ikuwonetsa kulimba kwa ma 450msa ndi 10% elongition. Beite imapangidwa ndi Ferrite ndi Carburization, yomwe ndi yopanga alumetete mankhwala. Kuti mupeze kuuma kwa ngale tokha, iyenera kuyerekezedwa kuchokera ku chisalowezi cha co-sitekisis (0.77%) chitsulo. Kuumitsa kwamphamvu kumatha kuyerekezera kuchokera pa chitsulo ndi ma carbon omwe amapezeka ochepera 0,0218%.
Muyezo: GB / T1348-2009 (m'malo mwa GB / T 1348-1988)
● Makhalidwe ndi kuchuluka kwa ntchito:
Ferrite mtundu duckile amaponya chitsulo, kulimba kwambiri komanso chipilala. Kutentha kochepa, kulimba mtima kumasintha kukhala bwinja, koma kutentha kochepa kumakhala kokwera, ndipo pamakhala kukana kwina kusintha kwamphamvu ndikukana kutupa. Imagwiritsidwa ntchito kwambiri lopukutira, mzere wolima, nyumba yosiyanitsa ndi thupi laulimi, ya valavu yochepa komanso yotsika kwambiri m'malo mwa makina ophatikizika.

● Kuyesa kutentha kwa kutentha ndi kutchuka kwachitsulo:
Kusintha kwa kutentha kwa kutentha: kuponyedwa kapena kuyika
Mitundu ya Allegraphic: Kuponyedwa: Graphite + Ferrite (matrix minofu) + ya Pearlite
Moyaka Chabwino: Mikanda Yambiri + ya Ferringe, imatha kupeza katundu wokwera kwambiri, makamaka mapiko a pikito ndi kulimbitsa thupi.
Qt600-3
Dzina la Zinthu: Chitsulo
● Makhalidwe ndi kuchuluka kwa ntchito:
Bead kuwala thupi lizidzana ndi ductoni chitsulo, ndi mphamvu yayikulu komanso yolimba, yovuta kwambiri komanso pulasitiki, yabwino kwambiri pokana komanso kugwedezeka kwabwino. Imatha kusintha momwe amagwirira ntchito mankhwala osiyanasiyana kutentha. Makamaka kugwiritsidwa ntchito kwa mitundu yonse ya magetsi amphamvu, Camshaft, kulumikiza shaft, kulumikiza ndodo, magiya, gluulic clinder block ndi zina
