Iwe unonzwa grey cast iron uye kusimba mukufema kwakafanana, uye yekutanga kuita kubva kune yakawanda shopu pasi vakomana ndeyekusahadzika shrug. Ndizvozvo. Kwemakumi emakore, zvave zviri zvinhu zvekushandisa-zvakachipa, zvinofanotaurwa, zvakanaka kunyorovesa, zviri nyore kugadzira. Asi zvinogoneka? Izvi zvaiwanzoreva kuti yaigona kushandiswazve, kupera kwenyaya. Mubvunzo chaiwo hausi wezvekugadzikiswa kwezvinhu; iri pamusoro peketani yose yemaitiro-kubva pakunyunguduka kusvika pakugadzira pasi kusvika kune chikamu chekuguma-kwehupenyu-uye kana isu tiri kuvandudza ipapo kana kungoita greenwashing. Ndakaona zvese.
Huremu hweNzvimbo Yenhaka
Ngatitange nekunyunguduka. Traditional cupola furnaces yegrey iron ihogi dzesimba uye emission sources. Kuchinjira kune yazvino magetsi induction kunyunguduka ndiyo nhanho iri pachena yekugadzira yakachena, asi iyo capex ine hutsinye kune yakajairika foundry. Haisi kungotenga choto chete; ndiyo gadziriro yemagetsi, basa reunyanzvi kuti rimhanye, iyo yakasiyana-siyana yekubata slag. Ndinoyeuka imwe nzvimbo yepakati yatakashanda nayo yakaedza kuenda nepakati, ichishandisa gadziriro yemafuta maviri. Pfungwa yaive yekushandisa gasi rechisikigo sehwaro uye magetsi ekugadzirisa zvakanaka. Yakanga iri chiroto chinotyisa—kugadzirisa nguva dzose, kemisitiri isingawirirani, uye pakupedzisira, mwero wezvirasha wakakwira. Vakadzokera shure. Chidzidzo chacho? Kuwedzera kwekuchinja pane legacy system kunowanzo gadzira tsvina yakawanda, kwete kushomeka. True innovation pano inoreva kuzvipira kwehurongwa hwakazara, inova yakaoma kutengesa kana miganho ichiyerwa nemasendi pakirogiramu.
Ipapo kune jecha. Green jecha kuumba, musana wegrey iron casting, inoshandisa bentonite ivhu. Iyo yakavharwa-loop system, theoretically. Asi mukuita, jecha rinoderedza. Iwe unowana yakafa ivhu kuvaka, kurasikirwa kunopisa kubva muguruva remarasha (seacoal) zvinowedzera, uye kudikanwa kwekugara uchirasa chikamu uye kuunza jecha idzva.
