METHOD AND DEVICE FOR HEATING AND COOLING MOLTEN METAL

Japanese Patent JP3014068

B2

PURPOSE: To eliminate slag developed after slag removal work in heating and cooling molten metal.
CONSTITUTION: The molten metal is poured into a mold 9 at the casting position fitted to a turn table, and by rotating the turn table, the mold 9 is shifted to a slag removal position to remove the floating slag on the molten metal surface. By again rotating the turn table, the mold 9 is shifted to a heating and water cooling position, and while heating with gas so as to remelt a part solidified in some degree on the molten metal surface, the water spray cooling is executed from the lower side of the mold 9 and the upper layer of about 50mm thickness is formed to the unsolidified molten layer 27 and the lower part below the above layer is formed to the solidified layer 26, and after heating treatment, by injecting the air, this molten layer is cooled rapidly.
