Kugadzirwa

Kwemakore makumi matatu nemashanu apfuura, indasitiri yesimbi uye yesimbi yaona shanduko dzakakosha. Muna 1980 716 MLN matani eSimbi akagadzirwa uye nyika dzinotevera dzaive pakati pevatungamiriri: USSR (21% yeGlobal Simbi Kugadzirwa), Japan (14%), Germany (6%), China (5%), China (5%), China (6%), China (5%), China (6%) ), Italy (4%), France nePoland (3%), Canada neBrazil (2%). Maererano neWorld Steel Service China inotanga kutanga uye iri pamberi pedzimwe nyika (60% yeGlobal Simbi Kugadzirwa), chikamu chedzimwe nyika kubva kumusoro-10 ndeye 2-8% - Japan (8%), 6%), South Korea neRussia (5%), Germany (3%), Turkey, Brazil naTaiwan (2%) (ona Mufananidzo 2). Kunze kweChina, dzimwe nyika dzakasimbisa zvigaro zvavo muIndia-10 ndege dzeKorea, Brazil neTurkey.

Kushandiswa

Simbi mune yese mafomu (yakakanda simbi, simbi uye yakamonerwa simbi) ndiyo yakanyanya kushandiswa zvekuvakwa zvinyorwa muhupfumi hwazvino hwenyika. Iyo inochengetedza nzvimbo inotungamira mukuvaka pamberi pehuni, kukwikwidza neiyo simende uye kufambidzana nayo (ferroconcrete), uye ichiri kukwikwidza nemhando mitsva yezvishandiso (polimers, ceramers). Kwemakore akawanda, indasitiri yeinjiniya yave ichishandisa zvinhu zvisingaite kupfuura chero imwe indasitiri. Pasi rose Steel Interption inozivikanwa neyekutsvaira maitiro. Iyo avhareji yekuwedzera chiyero chekushandiswa muna 2014 yaive 3%. Chiyero chakaderera chekukura chinogona kuoneka munyika dzakasimukira (2%). Kugadzira nyika dzine huwandu hwepamusoro hwekushandisa simbi (1,133 mln tonnes).
