Ferrosilicon inonzi ferroalloy inoumbwa nesimbi uye silicon.Ferrosilicon isimbi-silicon alloy yakagadzirwa nekunyungudutsa coke, simbi shavings, uye quartz (kana silica) muvira remagetsi.Sezvo silicon neokisijeni zviri nyore kusanganiswa kuita silicon dioxide, ferrosilicon inowanzoshandiswa se deoxidizer mukugadzira simbi.Panguva imwecheteyo, nokuti SiO2 inogadzira kupisa kwakawanda, inobatsirawo kuwedzera kupisa kwesimbi yakanyungudutswa panguva ye deoxidation.Panguva imwecheteyo, ferrosilicon inogona zvakare kushandiswa sechinhu chinowedzera alloying, uye inoshandiswa zvakanyanya mu low low alloy structural simbi, chitubu simbi, inotakura simbi, simbi inodzivirira kupisa uye yemagetsi silicon simbi.Ferrosilicon inowanzoshandiswa sechinhu chinoderedza mukugadzirwa kweferroalloy uye indasitiri yemakemikari.
Ferroalloy inoumbwa nesimbi nesilicon (ichishandisa silica, simbi, uye coke semidziyo, silicon iyo yakaderedzwa pakupisa kwakanyanya kwe1500-1800 madhigirii inonyungudutswa musimbi yakanyungudutswa kuita ferrosilicon alloy).Iyo yakakosha alloy akasiyana muindasitiri yekunyungudutsa.
Chigadzirwa tsananguro
(1) Inoshandiswa se deoxidizer uye alloying agents muindasitiri yesimbi.Kuti uwane kuumbwa kwemakemikari akakodzera uye kuvimbisa kunaka kwesimbi, muchikamu chekupedzisira chesimbi inofanira kuve yakasvibiswa.Kubatana kwekemikari pakati pesilicon neokisijeni yakakura kwazvo, Saka ferrosilicon yakasimba deoxi- dizer inoshandiswa mukuita sedimentation uye diffusion deoxidation yekugadzira simbi.Wedzera imwe chiyero chesilicon musimbi, inogona kuvandudza zvakanyanya kusimba, kuoma uye elasticity yesimbi.
(2) Inoshandiswa senge nucleating agent uye spheroidizing mumiriri muindasitiri yesimbi.Cast iron imhando yakakosha yemazuva ano maindasitiri simbi zvinhu, Yakachipa zvakanyanya kupfuura simbi, nyore kunyunguduka kunatsa, ine yakanakisa kukanda kuita uye seismic kugona kuri nani kupfuura simbi.Kunyanya iyo nodular cast iron, Yayo mechanical zvimiro pa kana padyo nemichina yesimbi.Wedzera imwe huwandu hwesilicon musimbi yakakandwa inogona kudzivirira simbi mukuumbwa, kukurudzira kunaya kwegraphite uye carbide spheroidizing.Saka mukugadzirwa kwesimbi nodular, ferrosilicon imhando yakakosha inoculants (Batsira kupatsanura kunze graphite) uye spheroidizing agent.
