1. Kucherwa nekugadzirisa simbi:
Kune marudzi maviri ehematite uye magnetite ane zvirinani kunyungudutsa kuita uye kukosha kwekushandisa.
2. Kuchera marasha nekubika:
Parizvino, inopfuura 95% yekugadzirwa kwesimbi pasi rose kuchiri kushandisa nzira yekugadzira iron yecoke yakagadzirwa neBritish Darby makore 300 apfuura.Nokudaro, coke inodiwa pakugadzira simbi, iyo inonyanya kushandiswa sehuni.Panguva imwecheteyo, coke zvakare inoderedza mumiriri.Bvisa iron kubva kune iron oxide.
Coke haisi mineral, asi inofanirwa "kunatswa" nekusanganisa mamwe marudzi emarasha.Chiyero chikuru ndeye 25-30% yemarasha emafuta uye 30-35% yemarasha ekubikira, uye wozoisa muchoto checoke uye carbonized kwemaawa 12-24., kugadzira coke yakaoma uye ine porous.
3. Kugadzira simbi yechoto:
Kuputika kwesimbi kugadzira simbi ndeyekunyungudutsa iron ore uye mafuta (coke ine basa rehuviri, rimwe sehuni, imwe sechinhu chinoderedza), limestone, nezvimwewo, muchoto chinoputika, kuitira kuti iite kudzikiswa kwekupisa kwakanyanya. uye inoderedzwa kubva kune iron oxide.Iyo inobuda ndeye "simbi yenguruve" inonyanya kuumbwa nesimbi uye ine kabhoni, kureva iron yakanyungudutswa.
4. Kugadzira simbi kuita simbi:
Musiyano wakakosha pakati pezvinhu zvesimbi nesimbi ndeye kabhoni yemukati, uye kabhoni yemukati iri pasi pe2% ndiyo chaiyo "simbi".Izvo zvinowanzonzi "steelmaking" ndeye decarburization yenguruve iron panguva yekupisa kwepamusoro-kunyunguduka, kushandura simbi kuita simbi.Inowanzo shandiswa simbi yekugadzira midziyo inoshandura kana choto chemagetsi.
5. Kukanda billet:
Parizvino, kunze kwekugadzirwa kwesimbi yakakosha uye yakakura-yakakura simbi castings, shoma shoma yesimbi yakakandwa ingots inodiwa pakugadzira kugadzirisa.Kugadzirwa kukuru kwesimbi yakajairika kumba nekune dzimwe nyika kwakasiya nzira yekare yekukanda simbi ingots - billeting - rolling, uye vazhinji vavo vanoshandisa Iyo nzira yekukanda simbi yakanyungudutswa mumabhiliti uye wobva waikungurusa inonzi "kuramba vachikanda" .
Kana iwe usingamirire kuti billet yesimbi itonhorere pasi, usamhara munzira, uye utumire zvakananga kune guyo rinoputika, unogona kuita zvigadzirwa zvesimbi zvinodiwa "mumoto mumwe".Kana iyo billet yakatonhodzwa nepakati uye yakachengetwa pasi, billet inogona kuva chinhu chinotengeswa mumusika.
6. Billet yakakungurutswa kuita zvigadzirwa:
Pasi pekukunguruka kweguyo, iyo billet inoshanduka kubva kune yakaoma kusvika kune yakanaka, ichiswedera pedyo uye ichiswedera kune dhayamita yekupedzisira yechigadzirwa, uye inotumirwa kubhedha yekutonhodza bhedha kuti itonhodze.Mazhinji emabhawa anoshandiswa kugadzirisa michina yezvimiro zvikamu uye zvichingodaro.
Kana mapatani emapumburu akashandiswa pane yekupedzisira bar yekupedzisa chigayo, zvinokwanisika kugadzira rebar, chinhu chechimiro chinonzi "rebar".
Sumo iri pamusoro pamusoro pekugadzirwa kweiyo rebar, ndinovimba ichabatsira kune wese munhu.
