Chii chiri kushandiswa kweFerrosilicon?

Ferrosiliconinoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri senge indasitiri yesimbi uye indasitiri yekuwana. Vanodya zvinopfuura 90% yeferrosilicon. Pakati pemhando dzakasiyana dzeferrosilicon,75% ferrosiliconndiyo inonyanya kushandiswa. Muindasitiri yesimbi, inenge 3-5kg ye75% ferrosiliconinopedzwa patani yese yesimbi inogadzirwa.

(1) Inoshandiswa se deoxidizer uye alloy muindasitiri yekugadzira simbi

Kuwedzera imwe chiyero chesilicon kusimbi kunogona kuvandudza zvakanyanya kusimba, kuoma uye elasticity yesimbi, kuwedzera magineti permeability yesimbi, uye kuderedza hysteresis kurasikirwa kwetransformer simbi. Kuti uwane simbi ine kugadzirwa kwemakemikari akakodzera uye kuve nechokwadi chemhando yesimbi, deoxidation inofanira kuitwa muchikamu chekupedzisira chekugadzira simbi. Silikoni neokisijeni zvine hukama hwakasimba hwemakemikari, saka ferrosilicon ine kunaya kwakasimba uye kuparadzira deoxidation maitiro pamaokisi ari musimbi.

Kuwedzera imwe huwandu hwesilicon kusimbi kunogona kuvandudza zvakanyanya kusimba, kuoma uye kuchinjika kwesimbi. Nokudaro, ferrosilicon inoshandiswawo sechigadziko kana ichinyungudutsa simbi yekugadzira (ine SiO300-70%), simbi yekushandisa (ine SiO.30-1.8%), chitubu chesimbi (ine SiO00-2.8%) uye silicon simbi ye transformers (ine silicon. 2.81-4.8%). Pamusoro pezvo, muindasitiri yesimbi, ferrosilicon poda inowanzoshandiswa sechinhu chinopisa chesimbi ingots kuvandudza kunaka uye kudzoreredza mwero wesimbi ingots kuburikidza nekutora mukana wehunhu hwekuti olefins inogona kuburitsa huwandu hukuru hwekupisa pakupisa kwakanyanya.

(2) Inoshandiswa seinoculant uye spheroidizer muindasitiri yesimbi yakakandwa

Cast iron chinhu chakakosha chesimbi muindasitiri yemazuva ano. Iyo yakachipa kupfuura simbi, iri nyore kunyunguduka, ine mashandiro akanaka ekukanda, uye inoshingirira zvakanyanya kukudengenyeka kwepasi pane simbi, kunyanya ductile iron, iyo ine michina inosvika kana kusvika kune mechanical maitiro esimbi. Kuwedzera imwe huwandu hweferrosilicon kukanda simbi kunogona kudzivirira kuumbwa kwecarbides musimbi uye kukurudzira kunaya uye spheroidization yegraphite. Nokudaro, mukugadzirwa kwesimbi ye ductile, ferrosilicon inokosha inoculant (iyo inobatsira kunaya kwegraphite) uye spheroidizer.

(3) Inoshandiswa sechinhu chinoderedza mukugadzirwa kwemavara matema

Haisi chete iyo silicon neokisijeni zvine yakakura makemikari affinity, asi iyo kabhoni yemhando yepamusoro-silicon ferrosilicon zvakare yakadzikira. Nokudaro, high-silicon ferrosilicon (kana siliceous alloy) inowanzoshandiswa kuderedza mumiririri mukugadzirwa kwepasi-carbon ferroalloys muindasitiri yeferroalloy. Ferrosilicon inogona kuwedzerwa kukanda simbi se ductile iron inoculant, uye inogona kudzivirira kuumbwa kwe carbides, kukurudzira kunaya uye spheroidization ye graphite, uye kuvandudza kushanda kwesimbi yakakandwa.

(4) Zvimwe zvinoshandiswa zveferro silicon

Ground kana atomize ferrosilicon poda inogona kushandiswa sechikamu chekumisa muindasitiri yekugadzira zvicherwa uye seye electrode coating muindasitiri yekugadzira magetsi. Yakakwira-silicon ferrosilicon inogona kushandiswa kugadzira zvigadzirwa senge organic silicon muindasitiri yemakemikari, kugadzirira semiconductor pure silicon muindasitiri yemagetsi, uye kugadzira organic silicon muindasitiri yemakemikari. Muindasitiri yesimbi, makirogiramu matatu kusvika mashanu e75% ferrosilicon anopedzwa patani yega yega yesimbi inogadzirwa.

Pamusoro peFerrosilicon

Ferrosiliconialloy yesimbi nesilicon. Ferrosilicon isimbi-silicon alloy yakanyungudutswa muvira remagetsi uchishandisa coke, simbi yakaraswa, uye quartz (kana silica) semidziyo. Mafomu akajairika eferrosilicon anosanganisira ferrosilicon zvimedu, ferrosilicon upfu, uye ferrosilicon slag. Mienzaniso yakananga inosanganisira ferrosilicon 75, ferrosilicon 70, ferrosilicon 65, uye ferrosilicon 45. Zvinyorwa zvinonyanya kugoverwa maererano nekusachena kwakasiyana-siyana mu ferrosilicon, uye tsanangudzo imwe neimwe ine kushandiswa kwayo kwakasiyana.

Ferrosilicon Production process

Theferrosiliconkugadzirwa muitiro ndiko kuderedza jecha kana nesilicon dioxide (Si) pamwe coke/ marasha (C), uye ipapo kuita nesimbi (Fe) inowanikwa mumarara. Iyo kabhoni iri mumarasha inoda kubviswa oxidized, ichisiya yakachena silicon uye zvigadzirwa zvesimbi.
Kugadzirwa kweFerrosilicon kunogona zvakare kushandisa yakadzika arc choto kunyungudutsa quartz nesimbi yakaraswa uye inoderedza mumiriri kuti igadzire inopisa mvura alloy, inounganidzwa mumubhedha wejecha. Mushure mekutonhora, chigadzirwa chinoputsika kuita zvidimbu zvidiki uye kuwedzera kupwanyika muhukuru hunodiwa.

Yepamberi Ferrosilicon Mugadziri

Zhenan Internationalane 20 makore echiitiko muferrosiliconproduction. Nemhando yepamusoro uye yakagadzikana kubuda, takagamuchira mirairo yakawanda uye yakawanda mumisika yepamba uye yekunze. Vashandisi veZhenan Metallurgical vanonyanya kugadzira kubva kuJapan, South Korea, Vietnam, India, United Arab Emirates, Brazil nedzimwe nyika. Zvigadzirwa zvedu zveferrosilicon zvinoshandiswa zvakanyanya mukugadzira simbi uye maitiro ekukanda. Nezvigadzirwa zvemhando yepamusoro uye masevhisi akavimbika, Zhen An International yakahwina mukurumbira wakanaka muindastiri. Zvigadzirwa zvekambani zveferrosilicon zvakasimbiswa nemasangano anozivikanwa seSGS, BV, ISO 9001, nezvimwe.
