METALLURGICAL TREATMENT METHOD ON A METAL BATH

摘要

The invention relates to a metallurgical treatment method on a metal bath. The inventive method comprises a first treatment involving the presence or formation of an acid slag on the surface of the metal bath and a second treatment involving the presence or formation of a basic slag on the surface of said metal bath. According to the invention, no intermediate deslagging is performed during said two processes, thereby ensuring that a physical separation exists between an acid slag zone and a basic slag zone on the surface of the metal bath.
