Ndeapi mashandisirwo eferrosilicon?

Ferrosilicon, alloy yesilicon nesimbi, inowanikwa mu45%, 65%, 75% uye 90% silicon mamakisi.Kushandiswa kwayo kwakakura kwazvo, ipapo mugadziri weferrosilicon Anhui Fitech Materials Co., Ltd achaongorora mashandisiro ayo chaiwo kubva pamapoinzi matatu anotevera.

Chekutanga, inoshandiswa se deoxidizer uye alloying mumiriri muindasitiri yekugadzira simbi.Kuti uwane simbi ine akakodzera makemikari ekugadzira uye kuve nechokwadi chemhando yesimbi, deoxidation inofanira kuitwa pakupera kwesimbi.Kubatana kwemakemikari pakati pesilicon neokisijeni yakakura kwazvo.Naizvozvo, ferrosilicon ideoxidizer yakasimba yekugadzira simbi, iyo inoshandiswa kunaya uye kuparadzira deoxidation.Kuwedzera imwe huwandu hwesilicon kusimbi kunogona kuvandudza zvakanyanya kusimba, kuoma uye elasticity yesimbi.
Nokudaro, ferrosilicon inoshandiswawo sechigadziro chekunyungudutsa simbi yekugadzira (ine silicon 0.40-1.75%), simbi yemidziyo (ine silicon 0.30-1.8%), simbi yechitubu (ine silicon 0.40-2.8%) uye silicon simbi ye transformer ( ine nesilicon 2.81-4.8%).

Uye zvakare, muindasitiri yekugadzira simbi, ferrosilicon poda inogona kuburitsa huwandu hukuru hwekupisa pasi pekupisa kwakanyanya.Inowanzo shandiswa seanopisa agent ye ingot cap kuvandudza kunaka uye kudzoreredza ingot.

Chechipiri, inoshandiswa seinoculant uye spheroidizing agent muindasitiri yesimbi yakakandwa.Cast iron chinhu chakakosha chesimbi muindasitiri yemazuva ano.Inochipa pane simbi uye iri nyore kunyungudutswa nekunyungudika.Iyo ine yakanakisa yekukanda zvivakwa uye zvirinani kuvhunduka kugona kupfuura simbi.Kunyanya nodular cast iron, maitiro ayo emuchina anosvika kana kusvika kune mechanical properties yesimbi.Kuwedzera imwe huwandu hweferrosilicon kukanda simbi kunogona kudzivirira kuumbwa kwecarbide musimbi uye kukurudzira kunaya uye spheroidization yegraphite.Naizvozvo, ferrosilicon yakakosha inoculant (kubatsira precipitate graphite) uye spheroidizing agent mukugadzirwa kwenodular cast iron.

Mukuwedzera, inoshandiswa seyekudzikisa mumiririri mukugadzirwa kweferroalloy.Kwete chete kuwirirana kwemakemikari pakati pesilicon neokisijeni yakakura, asiwo kabhoni yemhando yepamusoro yesilicon ferrosilicon yakaderera.Naizvozvo, yakakwira silicon ferrosilicon (kana siliceous alloy) yakajairika kuderedza mumiriri mukugadzirwa kweyepasi-kabhoni ferroalloy muindasitiri yeferroalloy.
