  • Method of manufacturing cooling plates for use in metallurgical furnaces and a cooling plate
    Patent number: 4572269
    Abstract: A cooling plate made up of three sections with expansion gaskets set at the boundaries thereof is produced by separate casting of molten metal into a foundry mold. Prior to pouring molten metal into the mold, partitions with the expansion gaskets are set in the mold to form molding cavities required to produce three sections, namely: an intermediate section and sections with protruded portions of the cooling pipes. The intermediate section may be likewise divided into several portions.
