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 ngefrikhwensi yamandla noma esithandweni somlilo esiphakathi nendawo, futhi izinga lokushisa lesithando somlilo liyi-1450 ° C. Indlela yokukhipha i-camshaft ye-cold-shock alloy ductile iron iwukubumba kwesihlabathi esiluhlaza, ukuphonsa okumanzi, futhi umswakama wesihlabathi sokubumba ungaphansi kuka-4%; izinga lokushisa elithelayo lingu-1340-1360 ° C; ugqinsi lwensimbi yokupholisa yangaphandle buyi-0.25-0.4 yobubanzi obungaphandle be-cam peach, nobubanzi bensimbi yokupholisa yangaphandle Ububanzi obufana nepentshisi ye-cam. insimbi yokupholisa yangaphandle ingusayizi we-radial we-cam peach ngemva kokuhlukana + izikhathi ezi-2 ukujiya kwensimbi ebandayo Ingaphakathi lensimbi yokupholisa elingaphandle liwusayizi wangempela we-radial wohlangothi lwebhokisi lepentshisi le-cam + 2mm ohlangothini olulodwa. I-periphery ingaba Noma yimuphi umumo, ngomthambeka ongu-1-2° ukusuka phansi kuye phezulu.
