Hot Metal Topping

During the continuous casting of non-ferrous metals and alloys like copper, brass or silver, the molten metals are particularly vulnerable to oxidation from ambient air. A protective layer of TIMREX® graphite on the surface of the molten metal bath prevents oxygen from oxidizing sensitive alloying elements and creating inclusions. Furthermore, the graphite provides thermal insulation and acts as a minor reducing agent for oxides already present in the melt. Ideal for oxygen-free copper.
