ABSTRACT:
The installation comprises a liquid container and an electrode holder located above said container and mounted with a provision for moving the electrode to the preset position relative to the casting. The container shell is made of two telescopically jointed parts with a pneumatic seal on the joint. Secured rigidly at the level of the upper face of the lower part of the shell is a casting support. A special mechanism delivers the casting onto the support and removes it therefrom. The casting is placed on the support with the upper part of the shell lowered which allows the positioning of the electrodes above the casting to be controlled visually. Then the movable part of the shell is raised, filled with water so as to cover the casting completely, and the cores are knocked out.
