Kodi ferrosilicon amagwiritsidwa ntchito bwanji?

Ferrosilicon, aloyi ya silicon ndi chitsulo, imapezeka mu 45%, 65%, 75% ndi 90% ya silicon.Kugwiritsa ntchito kwake ndikwambiri, ndiye wopanga ferrosilicon Anhui Fitech Materials Co., Ltd adzasanthula ntchito zake zenizeni kuchokera pamfundo zitatu zotsatirazi.

Choyamba, imagwiritsidwa ntchito ngati deoxidizer ndi alloying alloying mumakampani opanga zitsulo.Kuti mupeze zitsulo zokhala ndi mankhwala oyenerera komanso kuonetsetsa kuti zitsulo zili bwino, deoxidation iyenera kuchitika kumapeto kwa zitsulo.Kugwirizana kwamankhwala pakati pa silicon ndi oxygen ndi kwakukulu kwambiri.Choncho, ferrosilicon ndi deoxidizer wamphamvu pakupanga zitsulo, zomwe zimagwiritsidwa ntchito poyambitsa mpweya ndi kufalitsa deoxidation.Kuonjezera kuchuluka kwa silicon kuchitsulo kumatha kupititsa patsogolo mphamvu, kulimba komanso kukhazikika kwachitsulo.
Choncho, ferrosilicon amagwiritsidwanso ntchito ngati alloying wothandizila pamene smelting zitsulo structural (muna pakachitsulo 0.40-1.75%), chida chitsulo (muna pakachitsulo 0.30-1.8%), masika zitsulo (munali pakachitsulo 0.40-2.8%) ndi pakachitsulo zitsulo kwa thiransifoma ( okhala ndi silicon 2.81-4.8%).

Kuphatikiza apo, mumakampani opanga zitsulo, ufa wa ferrosilicon ukhoza kutulutsa kutentha kwakukulu pansi pa kutentha kwakukulu.Nthawi zambiri amagwiritsidwa ntchito ngati chotenthetsera cha kapu ya ingot kuti apititse patsogolo ubwino ndi kuchira kwa ingot.

Kachiwiri, amagwiritsidwa ntchito ngati inoculant ndi spheroidizing wothandizira pamakampani opanga chitsulo.Cast iron ndi chinthu chofunikira kwambiri pamakampani amakono.Ndiotsika mtengo kuposa chitsulo komanso mosavuta kusungunuka ndi kusungunula.Ili ndi zida zabwino kwambiri zoponyera komanso kugwedezeka kwabwinoko kuposa chitsulo.Makamaka nodular kuponyedwa chitsulo, ake makina katundu kufika kapena kuyandikira mawotchi zimatha zitsulo.Kuonjezera kuchuluka kwa ferrosilicon kuponya chitsulo kungalepheretse kupanga carbide mu chitsulo ndikulimbikitsa mpweya ndi spheroidization wa graphite.Choncho, ferrosilicon ndi yofunika inoculant (kuthandiza precipitate graphite) ndi spheroidizing wothandizira pakupanga nodular kuponyedwa chitsulo.

Kuphatikiza apo, imagwiritsidwa ntchito ngati chochepetsera pakupanga ferroalloy.Osati kokha kuyanjana kwamankhwala pakati pa silicon ndi mpweya wabwino, komanso mpweya wa silicon ferrosilicon wapamwamba ndi wotsika kwambiri.Chifukwa chake, silicon ferrosilicon yapamwamba (kapena aloyi ya siliceous) ndi njira yochepetsera wamba popanga ferroalloy ya carbon low mu ferroalloy industry.
