Kushandiswa kweferrosilicon inoculants: Parizvino, macamshaft epeturu nedhiziri injini anowanzo gadzirwa nesimbi, alloy cast iron, uye ductile iron, uye anoshandisa quenching kana kutonhora kuvhundutsa maitiro (alloy cast iron process) kuzadzisa zvakakwana kuita zvinodiwa.Nekudaro, simbi shafts uye ductile iron shafts haina kukodzera kune yakakwira-speed injini dzinopfuura 4000 rpm, uye kusimba kwekutonhora-kuvhundutsa alloy cast iron haina kukodzera kune simba rinodiwa einjini-saizi.
Basa referrosilicon inoculant nderekukunda tekinoroji iripo simbi kana ductile iron zvinhu hazvina kukodzera kune anti-kupfeka zvinodiwa zveinjini dzinomhanya-mhanya uye inotonhora-inovhundutsa alloy cast iron zvinhu haina kukodzera kusimba rezvinhu zvinodiwa zvepakati. uye yakaderera-speed injini, uye inopa nzira yakakodzera kune ese marudzi einjini.Iyo inotonhora-inovhundutsa alloy ductile iron uye camshaft casting nzira inoenderana nezvinodiwa zveinjini kusakara, kuramba kukwenya, spalling resistance, fatigue point contact mechanical simba, etc. Kushandiswa kweferrosilicon inoculant kunopindirana nemaitiro ekuvandudza injini kusvika pakunyanya kushandiswa. kuchengetedza simba.Iyo ferrosilicon inoculant inotora isina kurongeka yakakura-dose inoculation nzira, uye iyo yakazara silicon yemukati i1.9% -3.7%.Pre-furnace test inoratidza kabhoni yakaenzana neyekutanga inopisa simbi, iyo kabhoni yakaenzana nenodularizing agent (chaiyo yekuongorora yehuwandu hwekupisa) uye iyo carbon yakaenzana neferrosilicon inoculant (Iyo yose yekutora iri pakati pe4.3-4.55. inonyungudutswa mumagetsi emagetsi kana pakati pevheji yemoto, uye kutonhora kwechoto kunosvika 1450 ° C. Nzira yekukanda camshaft ye-cold-shock alloy ductile iron is green sand molding, wet casting, uye kuumbwa kwejecha hunyoro huri pasi pe4%; tembiricha yekudira ndeye 1340-1360 ° C; ukobvu hwekunze kwesimbi inotonhorera ndeye 0.25-0.4 yekunze kwedhayamita yecam peach, uye hupamhi hwekunze kwesimbi yekutonhodza Hupamhi hwakafanana necam peach. kunze kutonhora simbi ndiyo radial size yecam peach mushure mekuparadzana + 2 kaviri kukora kwesimbi inotonhora.Mukati memukati wekunze kwesimbi inotonhorera ndiyo chaiyo radial size yedivi recam peach box + 2mm kune rumwe rutivi. Iyo periphery inogona kuve Chero chimiro, ine mutsetse we1-2 ° kubva pasi kusvika kumusoro.
