  • Dumamawa Kafin Ƙarfe: Yana rage yawan zagayawan narkar da abinci, yana rage amfani da makamashi, kuma yana daidaita da yanayin EAF na "kusan babu carbon".

Haɗin gwiwar yin ƙarfe bisa hydrogen

  • Allurar Hydrogen ta Wutar Lantarki: Iskar gas mai wadataccen hydrogen (misali, H₂, iskar gas) tana maye gurbin wani ɓangare na coke, tana rage fitar da hayakin carbon.
  • Rage Kai Tsaye na Tanderu Mai Shaftar Hydrogen: Yana amfani da hydrogen a matsayin mai rage hayaki don rage ma'adinan ƙarfe kai tsaye, yana rage hayaki da fiye da kashi 60% idan aka kwatanta da tanderun fashewa na gargajiya.

IV. Kula da Inganci: Cikakken Tsarin Bibiya da Dubawa

Tsarin Binciken Blockchain na Kayan Aiki
Duba lambobin QR yana ba da damar shiga sanarwar kwastam, bidiyon gwajin sulfur, da bayanan rukuni na samarwa, yana tabbatar da bin ƙa'idodi.

Binciken Na'urar Nunin Electron
Masu duba inganci suna daidaita yawan lu'ulu'u ta hanyar amfani da na'urar hangen nesa ta lantarki, suna kawar da abubuwan da ke cikin silica-alumina don hana haɗurra a cikin simintin ƙarfe mai ƙarfi kamar ƙarfe na bawul ɗin nukiliya.

V. Yanayi da Fa'idodi na Amfani

Fitar da Zane Mai Kyau

  • Karfe na Bawul ɗin Nukiliya: Matsewar sulfur yana kulle abun da ke ciki ƙasa da 0.015%, yana hana tsatsa a ƙarƙashin yanayin zafi/matsi mai yawa.
