Ukusetshenziswa kwezijovo ze-ferrosilicon: Njengamanje, amakhamera kaphethiloli nezinjini zikadizili ngokuvamile enziwa ngensimbi, i-alloy cast iron, ne-ductile iron, futhi asebenzisa izinqubo zokucisha noma zokushaqeka okubandayo (inqubo ye-alloy cast iron) ukuze kuhlangatshezwane nezidingo zokusebenza okuphelele. Kodwa-ke, izinsimbi zensimbi nama-ductile iron shafts azifanele izinjini ezinesivinini esingaphezu kuka-4000 rpm, futhi amandla ensimbi exutshwe ne-cold-shock alloy cast awafanele izidingo zamandla ezinjini ezinosayizi ophakathi.
Umsebenzi we-ferrosilicon inoculant ukunqoba ubuchwepheshe obukhona bensimbi noma i-ductile iron material ayifanele izidingo eziphikisana nokugqoka zezinjini ezihamba ngesivinini esikhulu futhi i-cold-shock alloy cast iron material ayifanele izidingo zamandla we-medium. kanye nezinjini ezinejubane eliphansi, futhi inikeza indlela efanele zonke izinhlobo zezinjini. I-cold-shock alloy ductile iron kanye nendlela yokusakaza ye-camshaft ehlangabezana nezidingo zokumelana nenjini, ukumelana nokuklwebheka, ukumelana ne-spalling, amandla omshini wokuthinta indawo yokukhathala, njll. Ukusetshenziswa kwe-ferrosilicon inoculant kuhambisana nenkambiso yokuthuthukiswa kwenjini ekusetshenzisweni kancane futhi ukonga amandla. I-inoculant ye-ferrosilicon isebenzisa indlela yokujova yedosi enkulu engahleliwe, futhi inani eliphelele le-silicon liyi-1.9% -3.7%. Ukuhlolwa kwangaphambili kwesithando somlilo kubonisa ukulingana kwekhabhoni yensimbi yokuqala eshisayo, i-carbon elingana ne-nodularizing agent (ukuhlolwa kwangempela kwenani elivuthayo) kanye nekhabhoni elilingana ne-ferrosilicon inoculant (Inani eliphelele lokumuncwa liphakathi kuka-4.3-4.55. incibilikiswa kufrikhwensi yamandla noma isithando somlilo esiphakathi nendawo, futhi izinga lokushisa lomlilo linjalo 1450°C Indlela yokukhipha i-camshaft ye-cold-shock alloy ductile iron ukubunjwa kwesihlabathi esimanzi, futhi umswakama owubumbayo ungaphansi kuka-4% izinga lokushisa eliwu-1340-1360°C insimbi ingu-0.25-0.4 yobubanzi obungaphandle bepentshisi ye-cam, nobubanzi bensimbi yokupholisa yangaphandle Ububanzi obufanayo nekhamera. I-peach Ubude bensimbi yokupholisa yangaphandle ubukhulu be-radial be-cam peach ngemva kokuhlukana + izikhathi ezi-2 ubukhulu bensimbi ebandayo yangaphandle yensimbi yokupholisa ubukhulu bangempela be-radial yebhokisi le-cam + 2mm ohlangothini olulodwa I-periphery ingaba Noma yimuphi umumo, ngomthambeka ongu-1-2° ukusuka phansi kuye phezulu.
