Vessel Top

An electric arc furnace top vessel consists of 2 main parts: A steel vessel bottom lined with refractory material. The top of the tank equipped with tubular water-cooled panels. The top wall of the tank is equipped with a door for deslagging operations and openings for the passage of oxygen lances, oxyfuel burners or coal lances. The design of a tank top must take into account : The geometrical constraints for the installation of this auxiliary equipment. The multiple stresses to which the cooled elements are exposed (high thermal loads, mechanical shocks with scrap metal, etc.). The safety of use, maintenance and replacement operations of the water-cooled panels
