The electro-slag remelting (ESR) process is used to remelt and refine various steels grades resulting in high-quality ingots.
The electro-slag remelting process (ESR) is important because it provides better control of the solidification microstructure and chemical homogeneity. It also enables greater cleanliness and better mechanical properties. The manufactured high-alloyed with a controlled chemical composition are used in aerospace, in thermal- and nuclear-power plants, in chemical engineering and special tools.
To prevent absorption of gas, ESR unit is equipped with a neutral gas injection system with argon and nitrogen.
