High silicon ferrosilicon inonyungudutswa muchoto chemagetsi chinodzikisira chine kabhoni lining, uchishandisa silica, mafirita esimbi (kana masikero esimbi), uye coke semidziyo.Magetsi choto chemagetsi ferrosilicon kunyungudutsa inzira yemahara ye slag, uye zvigadzirwa zvinofanirwa kuve zvakachena uye zvisina madhaka, jecha, uye kumwe kusvibiswa.Kuwedzera huni machipisi nemarasha kumidziyo yevira kunogona kuvandudza kushanda kwayo.Munguva yekunyungudika, pamusoro pechinhu chacho chinowanzoita ganda uye "kuruma" (kupfapfaidza pamusoro), uye zvinodikanwa kugara uchi "putira choto".Iyo choto inogadzira silicon iron maawa ega ega 2-4 uye inoiumba kuita ingots ine ukobvu hwepasi pe100 millimeters.Kunyungudutswa kweferrosilicon kazhinji kunotora choto chemagetsi chakavhurika.Mumakore achangopfuura, kuitira kudzivirira kusvibiswa kwezvakatipoteredza, "low hood" kana "semi yakavharwa" mavhiri emagetsi ave achiwanzoshandiswa, ayo ari nyore kudzorera simba rekupisa uye kubvisa utsi neguruva;Kugadzirwa kwesilicon ferrosilicon yakakwira (ine silicon inodarika makumi manomwe neshanu) inonyanya kuitwa pachishandiswa choto chemagetsi chinotenderera kuderedza kuzunguzika kwechoto.

1. Inoshandiswa seinoculant uye spheroidizer muindasitiri yesimbi yakakandwa.Cast iron chinhu chakakosha chesimbi muindasitiri yemazuva ano.Iyo yakachipa pane simbi, iri nyore kunyungudutswa nekunyungudutswa, uye ine yakanakisa kukanda mashandiro uye zviri nani kupikisa seismic pane simbi.Kunyanya ductile iron, maitiro ayo emuchina anosvika kana kusvika kune ayo esimbi.Kuwedzera imwe huwandu hweferrosilicon kukanda simbi kunogona kudzivirira kuumbwa kwecarbides musimbi, kukurudzira kunaya uye spheroidization yegraphite.Nokudaro, mukugadzirwa kwesimbi inonzi ductile iron, ferrosilicon inokosha inoculant (inobatsira kuderedza graphite) uye spheroidizing agent.
2. Ferrosilicon inoshandiswa zvakanyanya muindasitiri yesimbi, indasitiri yekukanda, uye mamwe maindasitiri ekugadzira.Ferrosilicon yakakosha deoxidizer muindasitiri yekugadzira simbi.Mukugadzira simbi, ferrosilicon inoshandiswa kunaya deoxygenation uye diffusion deoxygenation.Chidhinha chakakandwa simbi chinoshandiswawo sealloying agent mukugadzira simbi.Kuwedzera imwe chiyero chesilicon kusimbi kunogona kuvandudza zvakanyanya simba rayo, kuoma, uye elasticity, kuwedzera magineti permeability, uye kuderedza hysteresis kurasikirwa kwetransformer simbi.Low aluminium ferrosilicon imhando yakakosha yeferrosilicon yakabuda mumakore achangopfuura.Kunyungudutsa kwayo kwakaoma uye kukosha kwakawedzerwa kwechigadzirwa kwakakwirira, iyo inzvimbo inoshingaira kuongororwa nevagadziri vakasiyana-siyana veferrosilicon.
