Ferrosilicon yakakosha ferroalloy inoshandiswa zvakanyanya musimbi metallurgy uye foundry indasitiri. Ichi chinyorwa chichazivisa zvizere magadzirirwo ekugadzirwa kweferrosilicon, kusanganisira kusarudzwa kwezvinhu, nzira dzekugadzira, kuyerera kwemaitiro, kutonga kwemhando uye kukanganisa kwezvakatipoteredza.
Raw zvinhu zvekugadzira ferrosilicon
Main mbishi zvinhu
Iyo mikuru yemidziyo inodiwa pakugadzirwa kweferrosilicon inosanganisira:
Quartz:Ipa silicon sosi
Iron ore kana zvimedu zvesimbi:Ipa iron source
Reducing agent:Kazhinji marasha, coke kana marasha anoshandiswa
Hunhu uye muyero weaya mbishi zvinhu zvinokanganisa zvakananga kugadzirwa kweferrosilicon uye kunaka kwechigadzirwa chekupedzisira.
Raw material yekusarudza maitiro
Kusarudza emhando yepamusoro zvinhu zvakasvibirira ndiyo kiyi yekuve nechokwadi chekubudirira kwekugadzirwa kweferrosilicon. Aya anotevera mamwe maitiro ekutarisisa pakusarudza raw materials:
Quartz: Quartz ine kuchena kwepamusoro uye silicon dioxide yemukati inopfuura 98% inofanira kusarudzwa. Izvo zvisina kuchena, kunyanya aluminium, calcium uye phosphorus zvinyorwa zvinofanira kunge zvakaderera sezvinobvira.
Iron ore: Iron ore ine yakakwira simbi yemukati uye yakaderera isina kuchena yemukati inofanirwa kusarudzwa. Chirafu chesimbi zvakare isarudzo yakanaka, asi kutarisisa kunofanirwa kubhadharwa kune iyo alloying element yemukati.
Reducing agent: Mushandi wekudzikisa ane high fixed carbon content uye low volatile matter and ash content inofanira kusarudzwa. Nokuda kwekugadzirwa kwepamusoro-soro ferrosilicon, marasha anowanzosarudzwa sechinhu chinoderedza.
Sarudzo yezvakagadzirwa haingokanganisa kunaka kwechigadzirwa, asi zvakare inokanganisa mutengo wekugadzira uye kukanganisa kwezvakatipoteredza. Naizvozvo, zvinhu izvi zvinofanirwa kutariswa zvizere pakusarudza zvigadzirwa.
Ferrosilicon nzira dzekugadzira
1. Electric arc choto nzira
Iyo yemagetsi arc furnace nzira parizvino ndiyo inonyanya kushandiswa nzira yekugadzira ferrosilicon. Iyi nzira inoshandisa tembiricha yakakwira inogadzirwa nemagetsi arc kunyungudutsa zvigadzirwa uye ine zvinotevera maitiro:
Kubudirira kwepamusoro:Inogona kukurumidza kusvika kune inodiwa tembiricha yakakwirira
Kudzora chaiko:Iyo tembiricha uye maitiro ekuita anogona kudzorwa nemazvo
Kuchengetedza zvakatipoteredza:Zvichienzaniswa nedzimwe nzira, ine kusvibiswa kushoma
Iyo nzira yekuyerera yemagetsi arc choto nzira inonyanya kusanganisira anotevera matanho:
Kugadzirira kwezvinhu zvakasvibirira uye batching
Furnace loading
Kupisa kwemagetsi
Kunyunguduka kuita
Kubvisa muchoto nekudurura
Kutonhodza uye kupwanya
2. Dzimwe nzira dzekugadzira
Pamusoro peiyo yemagetsi arc choto nzira, kune dzimwe nzira dzekugadzira ferrosilicon. Kunyange zvazvo isingashandiswi zvishoma, ichiri kushandiswa mune mamwe mamiriro ezvinhu:
Blast furnace nzira: Inokodzera kugadzirwa kwakakura, asi nekushandiswa kwesimba rakawanda uye yakakura kukanganisa kwezvakatipoteredza.
Induction choto nzira: yakakodzera batch diki, yakakwirira kuchena ferrosilicon kugadzirwa.
Plasma choto nzira: inosimukira tekinoroji, yakaderera simba rekushandisa, asi hombe yekudyara michina.
Idzi nzira dzine zvadzo zvakanakira nekuipira, uye kusarudzwa kweiyo nzira yekugadzira yakakodzera kunoda kutariswa kwakadzama zvichienderana nemamiriro chaiwo.
Ferrosilicon kugadzira maitiro
1. Raw material processing
Raw material processing inhanho yekutanga mukugadzirwa kweferrosilicon, kusanganisira zvinotevera zvinongedzo:
Kuongorora: Rongedza zvigadzirwa zvinoenderana nekukura kwechikamu
Kupwanya: Kupwanya zvimedu zvakakura zvezvinhu zvakabikwa kusvika pakukura kwakakodzera
Kuomesa: Bvisa hunyoro kubva kune zvigadzirwa kuti uvandudze kushanda zvakanaka kwekugadzira
Batching: Gadzirira chikamu chakakodzera chemusanganiswa wezvigadzirwa zvinoenderana nezvinodiwa zvekugadzira
Hunhu hwekugadziriswa kwezvinhu zvakasvibiswa hunokanganisa zvakananga kushanda kweiyo inotevera kugadzirwa kwemaitiro uye mhando yechigadzirwa, saka chinongedzo chega chega chinoda kunyatsodzorwa.
2. Kunyunguduka
Kunyungudutsa ndicho chinongedzo chepakati chekugadzirwa kweferrosilicon, iyo inonyanya kuitwa mumagetsi arc furnaces. Kunyungudika kunosanganisira matanho anotevera:
Kuchaja: Takura musanganiswa wakagadzirwa wakagadzirwa mubiravira remagetsi arc
Kudziisa magetsi: Pfuura ikozvino hombe muchoto kuburikidza neelectrode kuti ugadzire arc yekupisa
Kudzikisira kuita: Pakupisa kwakanyanya, iyo inoderedza mumiririri inoderedza silicon dioxide kune elemental silicon
Alloying: Silicon nesimbi zvinosanganiswa kuita ferrosilicon alloy
Kugadzirisa kuumbwa: Gadzirisa iyo alloy kuumbwa nekuwedzera huwandu hwakakodzera hwezvigadzirwa
Iyo yese yekunyungudutsa maitiro inoda kunyatso kudzora tembiricha, yazvino uye yakasvibirira yekuwedzera zvinhu kuti ive nechokwadi chekuita kwakatsetseka uye kugadzikana kwemhando yechigadzirwa.
3. Kuburutsa nekudira
Kana kunyungudutswa kweferrosilicon kwapera, kuburitsa nekudurura mabasa kunodiwa:
Sampling uye kuongorora:Sampling uye ongororo isati yaburitsa kuti ive nechokwadi chekuti alloy kuumbwa kunosangana nechiyero
Kuburutsa:Sunungura ferrosilicon yakanyungudutswa kubva muchoto chemagetsi arc
Kudira:Dururirai ferrosilicon yakanyungudutswa muforoma yakafanogadzirirwa
Kutonhodza:Rega iyo yakadirwa ferrosilicon itonhodze zvakasununguka kana kushandisa mvura kutonhora
Iyo yekuburutsa nekudurura maitiro inoda kutariswa kune yakachengeteka kushanda, uye tembiricha yekudurura nekumhanya kunofanirwa kudzorwa kuve nechokwadi chemhando yechigadzirwa.
4. Post-processing
Mushure mekutonhodza, ferrosilicon inoda kupinda munhevedzano yemashure-kugadzirisa maitiro:
Kupwanya:kupwanya zvidimbu zvakakura zveferrosilicon muhukuru hunodiwa
Kuongorora:kupatsanura zvichienderana nekukura kwechikamu chinodiwa nemutengi
Kurongedza:kurongedza iyo yakasarudzika ferrosilicon
Kuchengeta uye zvekufambisa:kuchengetedza uye kutakura maererano nezvinodiwa
Kunyangwe iyo post-processing process ichiita seyakapusa, yakakosha zvakaenzana pakuona mhando yechigadzirwa uye kusangana nezvinodiwa nevatengi.
Kudzora kwemhando yekugadzirwa kweferrosilicon
1. Raw material quality control
Raw material quality control ndiyo yekutanga mutsara wekudzivirira kuve nechokwadi chemhando yezvigadzirwa zveferrosilicon. Zvinonyanya kusanganisira zvinotevera zvinhu:
Supplier manejimendi: kumisikidza yakasimba mupi yekuongorora uye manejimendi system
Kuongorora kwezvinhu zvinopinda: sampling uye kuyedza batch yega yega yezvigadzirwa
Kuchengeta manejimendi: kuronga zvine hungwaru kuchengetwa kwezvinhu zvakabikwa kudzivirira kusvibiswa uye kuparara
Kuburikidza neyakaomesesa yemhando yehutongi hwemhando, njodzi yemhando mukugadzira maitiro inogona kuderedzwa zvakanyanya.
2. Kudzora maitiro ekugadzira
Production process control ndiyo kiyi yekuona kugadzikana kweferrosilicon mhando. Zvinonyanya kusanganisira zvinotevera zvinhu:
Maitiro parameter control:nyatso dzora makiyi ma parameter akadai tembiricha, zvazvino, uye mbishi zvinhu reshiyo
Online monitoring:shandisa advanced online monitoring michina yekutarisa kugadzirwa mamiriro munguva chaiyo
Maitiro ekushanda:gadzira nzira dzekushandisa dzakadzama kuti ive nechokwadi chekuti vashandisi vanodzitevedzera
Yakanaka yekugadzira dhizaini kutonga haingogone kuvandudza mhando yechigadzirwa, asi zvakare kuvandudza kugadzirwa kwakanaka, kuderedza kushandiswa kwesimba uye kushandiswa kwezvinhu.
3. Kuongororwa kwechigadzirwa
Kuongororwa kwechigadzirwa ndiyo yekupedzisira mutsara wekudzivirira kune ferrosilicon mhando yekudzora. Zvinonyanya kusanganisira zvinotevera zvinhu:
Kuongororwa kwemakemikari:tarisa zviri mukati mezvinhu zvakaita sesilicon, iron, uye kabhoni
Kuongororwa kwemidziyo yemuviri:kuona zvinhu zvemuviri zvakaita sekuoma uye density
Batch management:gadza yakazara batch manejimendi system kuti ive nechokwadi chekutevera chigadzirwa
Kuburikidza nekuongorora kwakasimba kwechigadzirwa, Zhenan Metallurgy inogona kuona kuti batch yega yega yeferrosilicon zvigadzirwa zvinotumirwa zvinosangana nemhando yemhando.
