Imveliso

Kwiminyaka engama-35 edlulileyo, ishishini lentsimbi kunye nentsimbi libone utshintsho oluphawulekayo.Ngo-1980 716 mln iitoni zentsimbi zaveliswa kwaye la mazwe alandelayo ayephakathi kweenkokeli: i-USSR (21% yemveliso yentsimbi yehlabathi), iJapan (16%), i-USA (14%), iJamani (6%), i-China (5%). ), eItali (4%), eFransi nasePoland (3%), eKhanada naseBrazil (2%).Ngokutsho kweWorld Steel Association (WSA), kwi-2014 imveliso yensimbi yehlabathi ifikelele kwi-1665 mln tonnes - ukunyuka kwe-1% xa kuthelekiswa no-2013. Uluhlu lwamazwe ahamba phambili lutshintshile kakhulu.I-China ibeka kuqala kwaye ikude kakhulu kwamanye amazwe (i-60% yemveliso yentsimbi yehlabathi), isabelo samanye amazwe ukusuka kwi-top-10 yi-2-8% - iJapan (8%), i-USA kunye ne-India (6%), eMzantsi. IKorea kunye neRashiya (5%), iJamani (3%), iTurkey, iBrazil kunye neTaiwan (2%) (jonga umzobo 2).Ngaphandle kweTshayina, amanye amazwe athe omeleza iindawo zawo kuluhlu oluphezulu yi-India, uMzantsi Korea, iBrazil kunye neTurkey.

Ukusetyenziswa

I-ayini kuzo zonke iintlobo zayo (intsimbi etyhidiweyo, intsimbi kunye nentsimbi eqengqelekayo) yeyona nto isetyenziswa kakhulu kwizinto zokwakha kuqoqosho lwale mihla lwehlabathi.Igcina indawo ekhokelayo kulwakhiwo phambi komthi, ikhuphisana nesamente kunye nokusebenzisana nayo (i-ferroconcrete), kwaye isakhuphisana neentlobo ezintsha zezinto zokwakha (iipolimeri, iiseramikhi).Kwiminyaka emininzi, ishishini lobunjineli belisebenzisa izixhobo ze-ferrous ngaphezu kwalo naliphi na elinye ishishini.Ukusetyenziswa kwentsimbi yehlabathi jikelele kubonakaliswa yindlela yokunyuka.Umyinge wokukhula kokusetyenziswa ngo-2014 ube sisi-3%.Izinga lokukhula elisezantsi lingabonwa kumazwe aphuhlileyo (2%).Amazwe asakhasayo anezinga eliphezulu lokusetyenziswa kwentsimbi (1,133 mln tonnes).
