Kugadzirwa uye maitiro

Ferrosiliconinogadzirwa nekuderedzwa kwesilica kana jecha necoke pamberi pesimbi.Mabviro esimbi isimbi yakaraswa kana misere.Ferrosilicons ine silicon yemukati inosvika gumi neshanu muzana inogadzirwa mumoto unopisa wakaiswa zvidhinha zvemoto acid.Ferrosilicons ine yakakwira silicon yemukati inogadzirwa mumagetsi arc furnaces.Magadzirirwo akajairika pamusika ferrosilicons ane 15%, 45%, 75%, uye 90% silicon.Yasara isimbi, ine inenge 2% ine zvimwe zvinhu zvakaita sealuminium necalcium.Kuwandisa kwesilica kunoshandiswa kudzivirira kuumbwa kwesilicon carbide.Microsilica chinhu chinobatsira byproduct.

A mineral perryite yakafanana neferrosilicon, nekuumbwa kwayo Fe5Si2.Pakusangana nemvura, ferrosilicon inogona kuburitsa hydrogen zvishoma nezvishoma.Mhedzisiro, iyo inokwidziridzwa pamberi pechigadziko, inoshandiswa kugadzira hydrogen.Iyo yekunyungudika uye kuwanda kweferrosilicon kunoenderana nesilicon yemukati, ine mbiri dzinenge-eutectic nzvimbo, imwe padyo neFe2Si uye yechipiri inotenderera FeSi2-FeSi3 yekuumbwa renji.

Uses

Ferrosiliconinoshandiswa sechitubu chesilicon kuderedza simbi kubva kuokisidhi yavo uye kuita deoxidize simbi uye mamwe ferrous alloys.Izvi zvinodzivirira kurasikirwa kwekabhoni kubva musimbi yakanyungudutswa (inonzi ichivharira kupisa);ferromanganese, spiegeleisen, calcium silicides, uye zvimwe zvinhu zvakawanda zvinoshandiswa kune chinangwa chimwe chete.Inogona kushandiswa kugadzira mamwe maferroalloys.Ferrosilicon inoshandiswawo kugadzira silicon, isingadziviriri uye inodzivirira kupisa-inodzivirira ferrous silicon alloys, uye simbi yesilicon yema electromotors uye transformer cores.Mukugadzira simbi yakakandwa, ferrosilicon inoshandiswa kupinza simbi kuti ikurumidze kuita graphitization.Mune arc welding, ferrosilicon inogona kuwanikwa mune mamwe ma electrode coatings.

Ferrosilicon ndiyo hwaro hwekugadzira prealloys senge magnesium ferrosilicon (MgFeSi), inoshandiswa kugadzira ductile iron.MgFeSi ine 3-42% magnesium uye mashoma mashoma-epasi simbi.Ferrosilicon yakakoshawo sechinhu chinowedzera kukanda simbi dzekudzora izvo zvekutanga zvesilicon.

Magnesium ferrosilicon inobatsira mukuumbwa kwemanodule, ayo anopa ductile iron midziyo yayo inochinjika.Kusiyana nesimbi yegrey cast, iyo inoumba graphite flakes, ductile iron ine graphite nodules, kana pores, izvo zvinoita kuti kutsemuka kuome.

Ferrosilicon inoshandiswawo muPidgeon process kugadzira magnesium kubva kudolomite.Kurapa kwe-high-silicon ferrosilicon nehydrogen chloride ndiyo hwaro hwemaindasitiri synthesis ye trichlorosilane.

Ferrosilicon inoshandiswawo muchiyero che3-3.5% mukugadzirwa kwemashizha emagetsi emagetsi emagetsi emagetsi.
