  • Production method for smelting clean steel from full-scrap steel using duplex electric arc furnaces
    Patent number: 10767239
    Abstract: A production method for smelting clean steel from full-scrap steel using duplex electric arc furnaces. Electric arc furnaces located in two positions are connected in series, wherein the electric arc furnace in a first position is dephosphorization electric arc furnace, and the electric arc furnace in a second position is a decarbonization electric arc furnace. The production method includes: performing smelting by combining a decarbonization electric arc furnace and 1-3 dephosphorization electric arc furnaces; a specific process of performing the smelting includes: in a charging period of the 1-3 dephosphorization electric arc furnaces, adding the full-scrap steel for the smelting, lime, slag in the decarbonization electric arc furnace, auxiliary materials and carbon powder or a carbon block into the dephosphorization electric arc furnace.
