METHOD FOR COOLING OXYGEN INFLUENCES IN THE OXYGEN TREATMENT OF RAW STEEL OR STEEL

摘要

In the process for cooling oxygen injection tuyères, having at least one cooling jacket, in the oxygen treatment of pig iron or steel in a metallurgical vessel, for example a bottom-blowing converter, Siemens-Martin furnace or electric furnace, a cooling fluid is passed through the cooling jacket. The cooling fluid used is a molten metal and this is circulated via a heat exchanger to remove the heat absorbed in the oxygen injection tuyère. IMAGE
