Carbon Baking

A carbon bake furnace is a special type of baking kiln for carbon blocks (or “anodes”) that are required in the aluminium production process. The anodes are made by mixing crushed coke or anthracite with a binding agent (example: coal tar pitch). When volatile components are heated over a period of time, the anode hardens, resulting in improved physical properties, such as electrical conductivity and resistance to oxidation.
