Kusarongeka kusarudzwa kwesimbi kwepfuti kunogona kukanganisa iko kwakajairika mashandiro bara nenyunje Machineuye kunogona kukonzera muchina kutadza.
Simbi yakapfura kuputika muchina, inowanzoshandiswa isimbi yekucheka piritsi, alloy piritsi, cast iron piritsi, iron piritsi uye zvichingodaro.
Vatengi vanoshandisa akapfura kuputika michina vanoda kutsvaga akakodzera simbi. Kusarudza mhando dzesimbi mhando dzemhando yepamusoro hazvingogone kuvandudza hupenyu hwevhisi yekupfurwa nemishini uye nhengo dzadzo dzakapfeka, asiwo zvinogadziridza zvemhando yezvigadzirwa. Kazhinji, sarudza masimbi esimbi. Mhando uye hukuru hwechinhu chikuru ndechokutarisa zvikamu zvakanatswa.
Simbi isina feri inowanzo shandisa aluminium pellets kana isimbi yesimbi isina chando:
Yakajairwa simbi uye nhengo dzayo dzakavhetemeswa, castings, simbi uye zvimwe zvigadzirwa zvesimbi;
Yakakura iyo dhayamuni yesimbi yakapfurwa, iyo yepamusoro yekukasira mushure mekuchenesa, asi yakanyanya kukwirira yekuchenesa;
Iyo isina kujairika simbi waya kana simbi waya yekucheka nekubudirira kweiyo isingadzoreki switch yakakwira kupfuura iyo yechitenderedzwa bhora, asi pamusoro roughness zvakare yakakwira;
Iyo inoshanda kwazvo projectiles inopedza michina nekukurumidza (yakafanana), asi chete nenguva yekushandisa, asi haina kumhanya zvakanyanya zvichienzaniswa nekubudirira kwekugadzira.
a) Uku kuomesa kunoenderana nekumhanya kwekuchenesa, asi zvakapindirana zvinoenderana nehupenyu. Naizvozvo, kuomarara kwakakwira, yekumhanyisa yekumhanyisa inokurumidza, asi hupenyu hupfupi hwakakura, saka kuomarara kunofanirwa kunge kuri pakati (nezve HRC40-50 yakakodzera).
b) Kuomesa zvine mwero, kwakanaka kudzokororwazve, kuti shots dzesimbi dzisvike pane imwe neimwe yekamuri yekuchenesa, nekudzora nguva yekugadzirisa.
c) Kuremara kwemukati senge blowhole cracks uye shrinkage magomba mu projectile kunogona kukanganisa hupenyu hwavo uye kuwedzera kushandiswa.
d) densities yemukati inowanzoita yakaderera kana huwandu hwayo hwanyanya kupfuura 7.4 kg / cc.
