What is the calculating formula of soderberg electrode in submerged arc furnace?

Answer 1

The Soderberg electrode in a submerged arc furnace is characterized by a self-baking design that utilizes a mixture of petroleum coke and coal tar pitch. The typical formula for calculating the resistance of the Soderberg electrode can be expressed as ( R = \frac{\rho L}{A} ), where ( R ) is the resistance, ( \rho ) is the resistivity of the electrode material, ( L ) is the length of the electrode, and ( A ) is the cross-sectional area. The efficiency and performance also depend on factors such as current density and temperature, which influence the electrode's electrical and thermal properties.
