CONTINUOUS CASTING METHOD

摘要

PURPOSE:To prevent erosion of moving belts made of a metal in the stage of continuous casting by a belt type continuous casting machine by pouring a molten material of the temp. lower than the casting temp. of a molten metal into a mold just prior to starting of casting the molten metal. CONSTITUTION:A molten material of the temp. lower than a molten metal is poured from a molten material pouring device 8 through a pouring pipe 9 into a mold 3 constituted of stationary mold walls 4 on the short side and moving belts 5 made of a metal on the long side just prior to starting of casting of the molten metal form a tundish 1 via an immersion nozzle 2. The intended molten metal is then cast into the molten material filled in the mold 3 through the nozzle 2 immersed therein. The jet of the molten metal poured therein contacts with the belts 5 after the flow rate thereof is decreased during passage through the inside of the molten material in the mold 3. The erosion of the moving belts made of the metal by the direct impact flow of the molten metal cast into the mold is thus prevented.
