Learn the Antioxidant Coating Process and Effectiveness of Graphite

When employing anti-oxidation coated graphite electrodes in electric arc furnace steel plants, modifications to the electrode holder are necessary. The inner diameter of the holder should be suitably enlarged, and a few arc-shaped graphite pads should be embedded to facilitate current conduction through the graphite electrode via the pads.

In 1970s resin-bonded magnesia-carbon refractory was introduced for electric arc furnace applications. Graphite became the principal carbon constituent in the magnesia-carbon refractory brick, where up to 35% C was added. In the 1980s the magnesia-carbon refractory brick was introduced in basic oxygen furnaces (Landy, 2004).

Cr7C3: A potential antioxidant for low carbon MgO¨CC refractories

EG can form high-temperature phases and oxidation products, and the generated materials can also be evenly distributed in refractories. By replacing 0.8% of graphite in the refractories with EG, the cold crushing strength, hot modulus of rupture, and thermal shock resistance of the MgO¨CC refractories were increased by 20%, 120%, and 30%
