Ferrosiliconialloy yesimbi nesilicon.Ferrosilicon is coke, steel chips, quartz (kana silica) seyakagadzirwa, yakanyungudutswa nevira remagetsi rakagadzirwa nesimbi silicon alloy.Nekuti silicon uye oksijeni zviri nyore kusanganisa musilicon dioxide, saka ferric silicon inowanzoshandiswa se deoxidizer mukugadzira simbi.Panguva imwecheteyo, nokuti SiO2 inogadzira kupisa kwakawanda, deoxidizing panguva imwe chete, inobatsirawo kuvandudza kutonhora kwesimbi yakanyunguduka.Panguva imwecheteyo, ferrosilicon inogonawo kushandiswa se alloying element additive, inoshandiswa zvakanyanya muzasi. alloy structural simbi, chitubu simbi, inotakura simbi, simbi isingasviki uye yemagetsi silicon simbi, ferrosilicon mukugadzirwa kweferroalloy uye indasitiri yemakemikari, inowanzoshandiswa sechinhu chinoderedza.

(1) Inoshandiswa se deoxidizer uye alloying agent muindasitiri yekugadzira simbi.Kuti uwane iyo inokodzera kemikari inoumbwa nesimbi uye ive nechokwadi chemhando yesimbi, muchikamu chekupedzisira chekugadzira simbi inofanira kuve deoxidized, silicon uye oksijeni pakati pemakemikari affinity. hombe, saka ferrosilicate is a strong deoxidizing agent inoshandiswa pakunaya uye kuparadzira deoxidization.Kuwedzera imwe silicon musimbi kunogona kuvandudza zvakanyanya kusimba, kuoma uye elasticity yesimbi, saka mukunyunguduka kwesimbi yekugadzira (ine silicon 0.40- 1.75%), simbi yemidziyo (ine Sio.30-1.8%), simbi yechitubu (ine Sio.40-2.8%) uye transformer silicon simbi (ine silicon 2.81-4.8%), ferrosilicon inoshandiswawo sechinhu chinosanganisa. panguva imwe chete, kuvandudza inclusions uye kuderedza zviri mukati gasi zvinhu musimbi yakanyungudutswa ndiyo inoshanda itsva tekinoroji yekuvandudza simbi yemhando, kuderedza mutengo uye kuchengetedza iron.Inonyanya kukodzera deoxidization yekunyungudutswa.simbi mukukanda kunoramba kuripo.Yakave yakaratidzwa nekuita kuti ferosilicate haisi kungosangana nezvinodiwa deoxidization yekugadzira simbi, asiwo ine desulfurization performance uye ine zvakanakira reshiyo huru uye kupinza kwakasimba.

Mukuwedzera, mumhizha yekugadzira simbi, ferosilicon powder inowanzoshandiswa se ingot cap heat agent kuti ivandudze kunaka uye kudzoreredza kweingot, kutora mukana wekuti ferosilicon powder inogona kupa kupisa kwakawanda kumusoro. tembiricha.

(2) Inoshandiswa seinoculant uye spheroidizer muindasitiri yesimbi yakakandwa.Kukandwa kwesimbi chinhu chakakosha chesimbi muindasitiri yemazuva ano.Yakachipa pane simbi, iri nyore kunyunguduka nekunyungudutswa, uye ine mashandiro akanaka ekukanda uye kugona kweasismic kuri nani pane simbi. Ductile iron, kunyanya, ine mechanical properties yakaenzana kana pedyo neiyo yesimbi.Kuwedzera chimwe chitsama cheferrosilicon mu simbi yakakandwa inogona kudzivirira kuumbwa kwecarbide musimbi, kukurudzira kunaya uye spheroidization yegraphite, saka mukugadzirwa kwenodular cast iron, ferrosilicon inokosha inoculant (kubatsira kunaya kwegraphite) uye spheroidizer.

(3) inoshandiswa seinoderedza mumiririri mukugadzirwa kweferroalloy.Hakusi chete kuwirirana kwemakemikari pakati pesilicon neokisijeni yakakura, asi carbon content yesilicon ferrosilicon yakakwirira yakaderera zvikuru.Naizvozvo, high silicon ferrosilicon (kana siliceous alloy) inowanzoshandiswa kuderedza. mumiririri mukugadzira yakaderera kabhoni ferroalloy muindasitiri yeferroalloy.

(4) 75# ferrosilicate inowanzoshandiswa mukunyunguduka kwe magnesium muPijiang magnesium muCaO.MgO inotsiviwa, toni imwe neimwe ye magnesium inopedza matani 1.2 eferrosilicate, iyo inotamba zvikuru. basa mukugadzirwa kwe magnesium.

(5) kune zvimwe zvinangwa. Yakagayiwa kana kuti atomized ferrosilicon powder inogona kushandiswa sechikamu chakamiswa muindasitiri yekugadzira mineral.Inogona kushandiswa sekuvhara kwe electrode muindasitiri yekugadzira electrode. High silicon ferrosilicon muindasitiri yemakemikari inogona kushandiswa kugadzira. silicone uye zvimwe zvigadzirwa.

Pakati pezvishandiso izvi, maindasitiri ekugadzira simbi, simbi, uye ferroalloy ndiwo anonyanya kushandisa ferrosilicate.Pamwe chete, anopedza zvinopfuura 90% yeferrosilicon.Mumhando dzakasiyana-siyana dzakasiyana dzeferrosilicon, inonyanya kushandiswa i75% ferrosilicon.Muindasitiri yekugadzira simbi. , inenge 3-5kg75% ferrosilicon inopedzwa kune imwe neimwe 1t yesimbi yakagadzirwa.
