Iyo yekugadzira maitiro yeRebar inonyanya kusanganisira matanhatu nhanho:
1. Iron Ore Mining uye Kugadzirisa:
Kune marudzi maviri ehematite uye magmetiti zvine hungwaru nendege yekuita uye kukosha kukosha.
2. Coal mining uye kukanda:
Parizvino, anopfuura 95% yekugadzirwa kweNyika yeNyika ichiri kushandisa nzira yekugadzira yeCoke-inogadzirwa neBritish Darby 300 makore apfuura. Naizvozvo, coke inodiwa pakugadzira simbi, iyo inonyanya kushandiswa sehuni. Panguva imwecheteyo, Coke zvakare kuderedza mumiririri. Dzinga simbi kubva pesimbi oxide.
Coke haisiri mumaminerari, asi anofanira kunge "kunatswa" nekusanganisa marudzi chaiwo emarasha. Iyo yakajairika ratio ndeye 25-30% yeakakora emarasha uye 30-35% yeCoking marasha, uye wozoiswa mucoke ovheni uye carbonized kwemaawa gumi nemaviri. , kugadzira zvakaoma uye zvinonaka coke.
3. Kuputsa chiridzwa chinonyatsonzwikwa:
Kuputika kwechirahwi cheva chinonyungudika ndekwekunyungudika. uye yakaderedzwa kubva pamubhedha wedzinza. Iyo yekubudira ndeyechokwadi "pig iron" inonyanya kuumbwa nesimbi uye ine imwe kabhoni, ndiyo yakaumbwa simbi.
4. Kuita simbi ive simbi:
Musiyano wakakosha pakati pezvivakwa zvesimbi uye simbi ndiyo kabhoni yezvinyorwa, uye iyo kabhoni zviri pasi pe2% ndiyo chaiyo "simbi". Izvo zvinowanzotaurwa nezve "Steelmaking" ndiko kuderera kweiyo pig iron panguva yekuwedzera-tembiricha yekunyepedzera, kutendeuka simbi ive simbi. Inowanzoshandiswa masimba masisitimu anoshandura kana chira chemagetsi.
5. Kukanda Billet:
Parizvino, kuwedzera mukugadzirwa kwesimbi yakasarudzika uye yakakura-yakakura simbi yekukanda, chidiki chidiki chekukanda masimbi mango zvinodikanwa kuti iite kugadziriswa. Iyo yakakura-chiyero kugadzirwa kwetimbi yakajairika kumba uye kunze kwenyika yakasiyiwa maitiro ekukanda simbi .
Kana iwe ukasamirira kuti Billet simbi kuti itonhore pasi, usapinda munzira, uye utumire zvakananga kugayo, unogona kugadzira zvigadzirwa zvesimbi "mumoto mumwe". Kana billet yakadzoreredzwa pakati uye yakachengetwa pasi, billet inogona kuve yakagadzirwa inotengeswa mumusika.
6. Billlet yakatenderera mune zvigadzirwa:
Pasi pekutenderera kwegall, billet shanduko kubva kuCoarse kuti ive yakanaka, kusvika padhuze uye pedyo neyakaipisisa yechigadzirwa, uye inotumirwa kumubhedha wekutonhora kwekutonhora. Mazhinji emabhawa anoshandiswa pakugadzirisa michina yemamiriro ezvinhu uye zvichingodaro.
Kana madhiri ehunyanzvi anoshandiswa paBar yekupedzisira kupedzisa bayo, zvinokwanisika kuburitsa rebar, chinhu chivakwa chinonzi "rebar".
Nhungamidzo iri pamusoro apa pamusoro pekugadzirwa kweRebar, ndinovimba zvichabatsira munhu wese.
