| 摘要 |
<p>This invention relates to an improved process for making steel in an electric arc furnace (EAF) using molten high carbon ferrous metal as a part of the EAF charge mix, which comprises preparing in/or introducing a molten high carbon ferrous metal (hot metal) into an EAF, said molten high carbon ferrous metal having a carbon content of less than 3 % and a silicon and manganese content of less than 0.2 % each, and a temperature of 1375 °C or higher in the furnace; adding a solid metallic charge selected from Scrap, HBI, DRI (Sponge, Pellet, etc. or Iron Ore) present singularly or in any combination together with lime into the hot metal inside the EAF; melting-cum-refining of the entire EAF charge mix in the absence of gaseous oxygen for carrying out said step of melting-cum-refining; superheating, finishing and tapping the molten steel into the ladle, for its subsequent casting.</p> |
