top-blown rotary converter process
Quick Summary
The top-blown rotary converter (TBRC) is a metallurgical process used in refining metals, particularly copper and steel. It's a type of converter, a vessel used to refine metals by blowing air or oxygen through a molten bath.
In the TBRC process, a cylindrical vessel is inclined and rotated. This rotation, combined with a lance that blows oxygen, air, or natural gas onto the molten bath, creates conditions for efficient smelting and oxidation. This method is advantageous as it can combine smelting and converting operations, utilizing the exothermic heat generated by the reactions. The TBRC is used in processes like the Noranda and Mitsubishi processes, which aim to improve efficiency and reduce emissions in metal refining.1
