Kugwiritsa ntchito majeti a ferrosilicon: Pakali pano, ma camshaft a injini ya petulo ndi dizilo nthawi zambiri amapangidwa ndi chitsulo, chitsulo cha alloy cast, ndi ductile iron, ndipo amagwiritsa ntchito njira zozimitsira kapena kuzizira (njira ya chitsulo cha aloyi) kuti akwaniritse zofunikira zonse. Komabe, zitsulo zachitsulo ndi ma ductile iron shafts sizoyenera injini zothamanga kwambiri kuposa 4000 rpm, ndipo mphamvu yazitsulo zozizira zazitsulo zozizira sizili zoyenera pa mphamvu za injini zapakati.
Ntchito ya ferrosilicon inoculant ndi kuthana ndi zitsulo zamakono kapena ductile chitsulo zinthu si oyenera odana kuvala zofunika injini mkulu-liwiro ndi ozizira-mantha aloyi kuponyedwa chitsulo zinthu si oyenera mphamvu zakuthupi zofunika sing'anga. ndi injini zotsika, ndipo amapereka njira yoyenera mitundu yonse ya injini. A ozizira-manyowetsa aloyi ductile chitsulo ndi camshaft kuponyera njira amakwaniritsa zofunika injini kuvala kukana, zikande kukana, spalling kukana, kutopa mfundo kukhudzana makina mphamvu, etc. Kugwiritsa ntchito ferrosilicon inoculant zikugwirizana ndi mchitidwe wa injini chitukuko cha mowa otsika ndi kupulumutsa mphamvu. The ferrosilicon inoculant utenga mwachisawawa lalikulu mlingo inoculation njira, ndi okwana pakachitsulo zili 1.9% -3.7%. Kuyeza kwa ng'anjo kusanachitike kumasonyeza kaboni wofanana ndi chitsulo choyambirira chotentha, mpweya wofanana ndi nodularizing agent (kuwunika kwenikweni kwa kuchuluka kwa moto) ndi mpweya wofanana ndi ferrosilicon inoculant (Kuchuluka kwa mayamwidwe kuli pakati pa 4.3-4.55. ndi smelted mu mphamvu pafupipafupi kapena wapakatikati pafupipafupi ng'anjo, ndi kutentha ng'anjo ndi 1450 ° C Njira yoponyera camshaft yachitsulo chachitsulo chogwedeza ndi mchenga wobiriwira, kuponyera konyowa, ndi kutentha kwa mchenga ndi 1340-1360 ° C; chitsulo ndi 0.25-0.4 wa m'mimba mwake akunja pichesi cam, ndi m'lifupi mwa chitsulo kuzirala kunja M'lifupi mofanana kamera. pichesi. Utali wachitsulo chozizira chakunja ndi kukula kwa radial ya pichesi ya cam pambuyo pa kupatukana + 2 nthawi ya makulidwe achitsulo chozizira chamkati chachitsulo chozizira chakunja ndi kukula kwenikweni kwa mbali ya bokosi la pichesi + 2mm mbali imodzi Yozungulira imatha kukhala yowoneka bwino, yokhala ndi malo otsetsereka a 1-2 ° kuchokera pansi mpaka pamwamba.
