Chinyorwa simbi. Batsirwa akadzokorora remelting

Nyaya ino inotsanangura kuti chinyorwa pamusoro dema simbi, nekuti icho chakaumbwa uye sei Re-kushandiswa indasitiri.

kutanga

With simbi vanhu vanoziva kubva panguva yakare, uye vakaita basa rinokosha pakuita kukura kwenzanga. The tanga chinyakare basa Ezvemutauro zvakagadzirwa nemhangura uye ndarira akazotevera, havasi simba zvakasiyana uye nokukurumidza yakapararawo. Kunyanya kana yaishandiswa zvombo. Asi pamwe kuwanikwa nzira kubvunda simbi esimbi, zvose zvakachinja. Sezvingatarisirwa, simbi haana kukwana, sezvo nedanho raro gadzira yave refu uye rakaoma, uye unhu ari murombo. Asi mukupera XVIII uye mangwanani XIX remakore marasha mugodhi kwakachinja zvose izvozvo. The itsva mafuta kuchatungamirira vakawanda kugadzirwa resimbi uye akaita kuti kwemaindasitiri. Asi chii chinonzi chinyorwa pamusoro matema simbi? Nei achiumbwa uye sei rinogona kushandiswa zvakare? In ichi isu vachanzwisisa.

mazwi

Maererano pamutemo tsananguro, chinyorwa simbi - ndiwo zita seboka pamusoro metallurgia indasitiri tsvina, tsvina simbi uye simbi zviyero, chakasakara. Zvinonzi akakamurwa munhu kushandiswa mune dunhu yechipiri, uye imwe chete iyo ichi hazvibviri. Zvichitaurwa zviri nyore, kuti ferrous simbi chinyorwa - ndiyo simbi, usina kushandiswa chinangwa chahwo, asi ari kuzodzosera remelting, zvinogona kushandiswa zvakare. Kuwedzera yepanyama panowanikwa muchimiro pakuguma upenyu mishonga, chinyorwa simbi anowanikawo sezvo tsvina neimwe indasitiri. Somuenzaniso, muna muchimiro Kudzingwa tsvina (Madonhwe), kana Chip pamwero pandaishanda lathes uye azvikuya michina. Nezvikonzero zvemari, zvikuru mari ferrous simbi chinyorwa itye zvakare, kuita zvimwe chete kubva mhangura.

Chimwe chinokosha ndechokuti kwezvakatipoteredza - simbi oxide zvigadzirwa anosvibisa zvishoma kupfuura dzisiri ferrous nesimbi, Somuenzaniso, imwe kutungamirira, asi dzose pakuchenesa madziva uye nenzvimbo dzokurasira esimbi ane kwaibatsira zvakatipoteredza.

Ferrous simbi: Types

Tapinda marara miti kana remelting, dema simbi nguva dzose anoenda zvaro, ngazviitwe, Pakutanga, mutsauko duku, asi hazvisi. First arongwe maererano mhando simbi: simbi, vakakanda simbi, Stainless simbi. Zvadaro, musi chikamu zviri kabhoni rakakamurwa makirasi maviri, zvadaro zvakare kupinda makirasi maviri maererano nokuwanda alloying zvinhu. Final kuparadzana kunoitika quality, ayo yose madhigirii 28. Uye chete pashure kuti akanga asina kutumwa kuti muchanyauswa pasi. Non-ferrous nesimbi kuoma kukunda kuti, asi ngatirege kugara pamusoro payo, sezvatinokurukura chete chinyorwa.

Zvikonzero uye zvakanakira

Sezvambotaurwa, chimwe nei marara ane upfumi vanobatsirwa uyewo nyore tsvina simbi Marara, iwe wotanga chirongwa gadzira rayo kubva muvare. Asi, sezvo chero muitiro, remelting chinyorwa rinobatanidza dzinoverengeka dzimwe migumisiro zvinokosha.

Chokutanga, deposits esimbi esimbi kwezvinoshandiswa zvakasimba. Kunyange chikamu muvhu nechepasi riri guru kwazvo zvichienzaniswa vamwe, asi vanhu kwemakore anopfuura zana makore navanopinda maindasitiri chikero zvavo.

Chechipiri, shoma huni kushandiswa nokuda kubvunda mhangura - marasha - reserves vari kure risingaperi. Izvi dzinosanganisira rutapudzo pakati kabhoni dioxide mumhepo uye, sezvo migumisiro inokudza maturo. In shoko - ferrous uye asiri ferrous nesimbi uye kubudiswa zvinobatsira kuti hurumende upfumi uye zvakatipoteredza yose.

Tsika iyi iripo mune zvose dzakabudirira, anopfuura makore ane zana.

Business

Mushure pokuwa USSR uye mazano ari capitalist zvoupfumi munyika dzaichimbova akatanga kukura uye kuparadzira basa pasiri paruzhinji. Uye mumwe kwemarudzi ake - iri Nzira ine ferrous uye nonferrous chinyorwa simbi kubva vagari. Uyezve, kugadzirwa patsva pasi zvebhizimisi rose, izvo kwemakore kana kuva soka nguva yava vaunganidza guru uwandu yamatare.

Uye mazuva ano basa iri kwakapararira munzvimbo dzinenge mumusha ose unogona kuwana nzvimbo kutora dema kana mavara simbi. Mitengo pamusoro pake, kunyange asina kusvinwa kupinda yakaoma framework, asi vachiri akasiyana zvishoma zvichienderana nharaunda.

USSR

Mumakore Soviet Union uyewo kwaiwanzoitwa pamwero mukuru zviito nokuda simbi muunganidzwa. Chinyorwa uye tsvina ferrous nesimbi nokudzura vechikoro, vashori uye vamwe vagari vari pachavo nenzira, uye paruzhinji, kana Somuenzaniso, pane imwe muzvipiri vadzidzi Institute kana zvavanobata chirimwa aifanira compulsorily vatore tani kana maviri dzesimbi kupfuura. Nokuti ziso kurudziro kazhinji musi May Day kufora kufanorongwa pamusoro nematarakita anofamba nemotokari zvakanga zvakakwana nesimbi imwe mhando, akawana Koshanda.
