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 imapereka 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. imasungunuka mu mphamvu yafupipafupi kapena ng'anjo yapakati, ndipo kutentha kwa ng'anjo ndi 1450 ° C. Njira yopangira camshaft ya chitsulo chozizira cha alloy ductile chitsulo ndi kuumba kwa mchenga wobiriwira, kuponyera konyowa, ndipo mchenga wowuma umakhala wosakwana 4%; Kutentha kothira ndi 1340-1360 ° C; makulidwe a chitsulo chozizira chakunja ndi 0.25-0.4 chakunja kwa cam pichesi, ndi m'lifupi mwake chitsulo chozizira chakunja M'lifupi mwake monga pichesi ya cam. chitsulo choziziritsa chakunja ndi kukula kwa radial kwa pichesi ya cam pambuyo pa kupatukana + 2 nthawi ya makulidwe achitsulo ozizira. Zozungulira zimatha kukhala mawonekedwe aliwonse, okhala ndi otsetsereka 1-2 ° kuchokera pansi mpaka pamwamba.
