The device to protect the clogging of submerged entry nozzle for a continuous caster

摘要

The present invention is designed to prevent clogging of a continuous casting machine immersion nozzle, more specifically, a tundish for supplying molten steel, to prevent the inclusion of inclusions on the duct of the immersion nozzle for controlling the flow of molten steel supplied to the lower mold. The present invention relates to a device for preventing clogging of a continuous casting machine immersion nozzle, in which a ring body applying a magnetic field is installed to suppress drift of molten steel due to clogging of the nozzle and mass production of high quality cast steel.;That is, the electromagnetic ring is provided on the bottom of the tundish to generate a magnetic field by supplying a DC current to the pipe wall of the upper nozzle to connect the immersion nozzle to form a magnetic field on the inclined surface of the upper nozzle, the electromagnetic ring is It consists of a core that provides durability and a coil wound in a spiral and a direct current flows, so that the inclusions raised around the inclined surface of the upper nozzle due to the force acting around the electromagnetic ring are not attached to the nozzle surface and are separated from the upper nozzle. By applying the force, the separation of the inclusions in the molten steel was further activated.
