Russia is the biggest steel producer in Europe. The pressure is high on Russia’s steel industry to follow the strict market demands for quality and economy in steel production. Big investments for revamping of existing units or erection of new units for ladle refining of liquid steel are the imperative consequences. Together with SMS Mevac ladle metallurgical units have already been implemented for 40 years. Four new RH units, embedded in different production lines and with different metallurgical tasks, are described as examples of this.
