Product Overview
Foundries pay insufficient attention to protecting the molten metal stream as it exits from the bottom-pour ladle during the casting process. Oxide films readily form on the surfaces of the metal streams, then through metal turbulence these films are entrained in the metal, and new oxide layers form. These films often exist as bi-films and initiate many defects in the casting, degrading the physical properties. For many years continuous casters of metals have been using processes to protect the metal streams during casting. Foundries are now able to enhance their casting quality using a shrouding concept.
