The RH process has been named after Ruhrstahl and Heraeus, where this process was initially developed in 1950. The RH circulation degassing process has proved its vast suitability in large number of shops worldwide, for operation with short tap to tap time covering heat sizes upto 400 tons. The vacuum treatment in RH plants produces steel which fulfills the demand of high steel quality.
