Melting steel supply apparatus for continuous casting, and continuous casting method for the same

摘要

"FUSION STEEL SUPPLY APPLIANCE FOR CONTINUOUS CASTING, AND CONTINUOUS CASTING METHOD FOR THE SAME". An apparatus for supplying molten steel and a method of continuous casting with it are described. The appliance is equipped with an intermediate pan 1 that has an upper nozzle 2 at the bottom, a flow control mechanism 3 located below the upper nozzle 2, an immersion nozzle 4 formed by a refractory material that has good electrical conductivity, a electrode 5 disposed in the inner space of the intermediate pan 1, the other electrode 6 placed in the immersion nozzle 4, and a power supply 7 connected to electrodes 5 and 6. According to the method, the molten steel is supplied to a mold in the state supplying an electric current between the internal surface of the immersion nozzle 4 and the molten steel 8 that passes through the interior of the same using the apparatus to supply molten steel. The deposition of AI oxide or similar in the molten steel on the internal surface of the immersion nozzle and others can be avoided, and with this the generation of surface defects in the products can also be avoided.
