(1) Inoshandiswa se deoxidizer uye alloying mumiriri muindasitiri yekugadzira simbi. Kuti uwane simbi ine akakodzera makemikari kuumbwa uye kuve nechokwadi chemhando yesimbi, deoxidation inofanira kuitwa muchikamu chekupedzisira chekugadzira simbi. Kubatana kwemakemikari pakati pesilicon neokisijeni yakakura kwazvo, saka ferrosilicon chinhu chakakosha deoxidizer muindasitiri yekugadzira simbi. Mukugadzira simbi, kunze kwezvimwe simbi dzinofashaira, dzinenge mhando dzese dzesimbi dzinoshandisa ferrosilicon sechinhu chakasimba che deoxidizer yekunayisa deoxidation uye diffusion deoxidation. Kuwedzera imwe huwandu hwesilicon kusimbi kunogona kuvandudza zvakanyanya kusimba, kuoma uye elasticity yesimbi. Nokudaro, inoshandiswa zvakanyanya mukunyungudutsa simbi yekugadzira (ine siO. 40% ~ 1.75%) uye simbi yekushandisa (ine siO. 30%). ~ 1.8%), chitubu simbi (ine Si O. 40% ~ 2.8%) uye mamwe marudzi simbi, imwe uwandu ferrosilicon inofanira kuwedzerwa sezvo alloying mumiririri. Silicon zvakare ine hunhu hwehukuru hwakanyanya kuramba, hurombo hwekupisa conductivity uye yakasimba magineti conductivity. Simbi ine imwe huwandu hwesilicon, iyo inogona kuvandudza magineti permeability yesimbi, kuderedza hysteresis kurasikirwa, uye kuderedza eddy ikozvino kurasikirwa. Nokudaro, ferrosilicon inoshandiswawo sechigadziro chinoshandiswa pakunyungudutsa simbi yesilicon, yakadai sesimbi yakaderera yesilicon yemamotors (ine Si O. 80% kusvika 2.80%) nesilicon simbi ye transformers (ine Si 2.81% kusvika 4.8%). use.
Uye zvakare, muindasitiri yekugadzira simbi, ferrosilicon poda inogona kuburitsa huwandu hwekupisa kana hwapiswa pakupisa kwakanyanya uye inowanzoshandiswa sechinhu chinopisa chesimbi ingot caps kuvandudza kunaka uye kudzoreredza chiyero chesimbi ingots.
(2) Inoshandiswa seinoculant uye spheroidizing mumiriri muindasitiri yesimbi yakakandwa. Cast iron chinhu chakakosha chesimbi muindasitiri yemazuva ano. Iyo yakachipa kupfuura simbi, iri nyore kunyunguduka uye kunyungudutswa, ine yakanakisa kukanda zvivakwa uye zviri nani kuramba kudengenyeka kwepasi pane simbi. Kunyanya ductile iron, maitiro ayo emagetsi anosvika kana ari pedyo neaya esimbi. performance. Kuwedzera imwe huwandu hweferrosilicon kukanda simbi kunogona kudzivirira kuumbwa kwecarbides musimbi uye kukurudzira kunaya uye spheroidization yegraphite. Nokudaro, mukugadzirwa kwesimbi inonzi ductile iron, ferrosilicon inokosha inoculant (inobatsira kuderedza graphite) uye spheroidizing agent. .
(3) Inoshandiswa seanoderedza mumiririri mukugadzirwa kweferroalloy. Haisi chete kuwirirana kwemakemikari pakati pesilicon neokisijeni zvakanyanya, asi iyo kabhoni yemhando yepamusoro-silicon ferrosilicon yakadzikira. Naizvozvo, yakakwira-silicon ferrosilicon (kana silicon alloy) inowanzoshandiswa kuderedza mumiriri muindasitiri yeferroalloy kana ichigadzira yakaderera-kabhoni ferroalloys.
