Electroslag remelting process (ESR)

Electroslag remelting process (ESR)

In the electroslag remelting process, the starting material is immersed in a slag bath of a mold. This creates a resistance in the existing circuit. The resulting heat melts the material. Non-metallic inclusions and sulfur remain in the slag and are subsequently separated. What remains is a steel of special purity and homogenous structure with improved material properties.
