Steel making process |
| abstract |
A process for making carbon steel and low-alloy steel in a basic oxygen furnace is disclosed, which comprises preparing a molten metal suitable for producing the steel in said basic oxygen furnace, carrying out the top-blowing of oxygen gas and bottom-blowing of carbon dioxide gas and then tapping the resulting molten steel. The top-blowing oxygen gas is injected through a lance onto the molten metal at an outlet velocity of Mach 0.8-2.0. |
