Svondo rapfuura, mitengo yezvinhu zvemumba yakasiyana-siyana. Mitengo yesimbi yakachinja-chinja ikadzika, mitengo yecoke yakaramba yakagadzikana, mitengo yemusika wecoking coal yakagara yakagadzikana, mitengo yealloy yakajairika yakanga yakagadzikana zvishoma nezvishoma, uye mitengo yealloy chaiyo yakaderera. Kuchinja kwemitengo yemhando huru ndekwekuti:

Kutengeswa kwemitengo yesimbi inopinzwa munyika kunoshamisa

Svondo rapfuura, musika wesimbi inopinzwa kunze kwenyika wakachinja-chinja, mutengo weplate yekunze uye mutengo wechiteshi chengarava uchidzikira zvishoma zvichienzaniswa nevhiki rapfuura, kunyanya nekuda kwekuderera kwechinguvana kwekudiwa kwesimbi nekuda kwemuganho wekugadzirwa kwesimbi dzekuchamhembe. Panguva imwe chete, purofiti yesimbi inodzvinyirirwa, kufarira kutenga simbi hakuna kukwira, kazhinji kunochengetedza mamiriro ekushandisa akaderera. Nekuda kwechiziviso chakagamuchirwa pamusoro pezvinodiwa zvemuganho wekugadzira, kugadzirwa kwesimbi isina kuchena kwegore ra2021 hakufanirwe kunge kwakakwira kupfuura gore rapfuura, zvinoreva kuti hafu yechipiri yesimbi ichange iine muganho mukuru wekugadzirwa, munguva pfupi simbi haisati yave nematanho chaiwo, kudiwa kwesimbi kunoramba kwakakwira, asi munguva refu, senge kuiswa kwepamutemo kwemuganho wekugadzira, kudiwa kwesimbi kuchadzikira zvakanyanya.

Mutengo wekutengeserana kwecoke wesimbi wakasimba

Svondo rapfuura, mutengo wekutengeserana kwesimbi yekoke yemuno wakadzikama.

Musika wemarasha ekubikisa wakagadzikana

Svondo rapfuura, mitengo yemusika wecoking coal mudzimba yakanga yakadzikama zvakanyanya, nemigumisiro yakasiyana mune dzimwe nzvimbo, uye mizhinji yemigodhi yemarasha yakanga yamisa kugadzirwa yakanga ichigadzirira kutangazve kugadzirwa. Parizvino, migodhi yemarasha yakamisa kugadzirwa munzvimbo huru dzekugadzira iri kutangazve basa nekugadzirwa, asi mabhizinesi mazhinji ecoking ari pasi pemutemo anoda kuzadza nzvimbo yekuchengetera, uye kuwanikwa kuchiri kushoma munguva pfupi iri kutevera. Zvinotarisirwa kuti mutengo wemukuru wesangano recoking coal mudzimba uchakwira zvakanyanya munguva pfupi iri kutevera, uye mutengo wemarasha mumusika wakasiyana.

Mitengo yeFerroal yakasanganiswa

Vhiki rapfuura, mitengo yeferroalloy yakasanganiswa. Mitengo yeFerrosilica, silicon manganese yakakwira zvishoma nezvishoma, mitengo yeferrochrome ine kabhoni yakakwira zvakanyanya; Mutengo weVanadium nitrogen alloy wakakwira zvishoma, mutengo wevanadium iron wakaderera zvishoma, mutengo weferromolybdenum unoramba uchidzikira zvishoma. Kunyanya:

Mitengo yemusika weFerrosilicon yakaramba ichikwira.
