CONTROL METHOD FOR MOLD OSCILLATION OF CONTINUOUS CASTER

摘要

A mold vibration control method of a continuous casting machine is provided to perform high speed casting in continuous casting so as to secure superior slab quality and productivity. A mold vibration control method of a continuous casting machine comprises a step of putting molten steel produced through electric furnace-refining furnace in a ladle(1) and moving it to the continuous casting machine, a step of moving the molten steel in the ladle to a tundish(2), and a step of moving a fixed amount of the molten steel in the tundish to a mold(3) through a submerged nozzle. The mold is made of copper plate. The molten steel put in the copper mold is cooled by water and taken out of the mold, and then passes through a water spray(4) to be cooled and completed. The completely molded steel is cut into a fixed size of slab(5). The mold vibration is controlled so that the frequency decreases at the fixed slope according to casting speed and the up and down displacement increases at the fixed slope.
