Umkhiqizo

Eminyakeni engama-35 edlule, imboni yensimbi nensimbi ibone izinguquko ezibalulekile. Ngo-1980 716 amaTonnes ensimbi akhiqizwa futhi lawo mazwe alandelayo ayephakathi kwabaholi: I-USSR (21% yokukhiqizwa kwensimbi yomhlaba wonke), iJapan (16%), iJalimane (6%), iChina (5% ), I-Italy (4%), iFrance nePoland (3%), eCanada neBrazil (2%). Ngokusho kwe-World Steel Association (WSA), ekukhiqizeni kwensimbi yango-2014 kufinyelele kumathani we-1665 MLN - ukusukuma okungu-1% ngokuqhathaniswa no-2013. Uhlu lwamazwe aholayo luguqukile kakhulu. I-China iqala kuqala futhi ingaphezulu kwamanye amazwe (60% wokukhiqizwa kwensimbi yomhlaba wonke), isabelo sakwamanye amazwe kusuka ku-Top-10 ngu-2-8% - I-Japan (6%), eningizimu ne-India (6%), South I-Korea neRussia (5%), iJalimane (3%), iTurkey, iBrazil neTaiwan (2%) (bheka umfanekiso 2). Ngaphandle kweChina, amanye amazwe aqinise izikhundla zawo ezindaweni eziphezulu-10 yiNdiya, eSouth Korea, eBrazil naseTurkey.

Ukudliwa

I-Iron kuzo zonke izinhlobo zayo (i-cast iron, insimbi kanye nensimbi egoqiwe) yiyona esetshenziswa kakhulu yokwakha emnothweni wanamuhla womhlaba. Igcina indawo ephambili ekwakhiweni ngaphambi kwezinkuni, ukuncintisana nosimende nokuxhumana nayo (i-Ferroconcrete), futhi namanje nokuncintisana nezinhlobo ezintsha zezinto zokwakha (ama-polimer, ceramics). Iminyaka eminingi, imboni yezobunjiniyela ibisebenzisa izinto ezinamandla ngaphezu kwanoma yimuphi omunye imboni. Ukusetshenziswa kwensimbi yomhlaba wonke kubonakaliswa yinkambiso ephakeme. Izinga lokukhula okujwayelekile ukusetshenziswa ngonyaka ka-2014 lalingu-3%. Izinga lokukhula eliphansi lingabonakala emazweni athuthukile (2%). Amazwe asathuthuka anezinga eliphakeme lokusetshenziswa kwensimbi (1,133 mln tonnes).
