IMMERSION NOZZLE OF CONTINUOUS CASTING APPARATUS

摘要

PURPOSE: An immersion nozzle of a continuous casting apparatus is provided to minimize the defects of a product by suppressing the inclusion of external slag into the inside of melt steel or the generation of bubbles. CONSTITUTION: An immersion nozzle(100) of a continuous casting apparatus comprises a main body, a flow path, and a molten steel ejection hole(110). The main body is detachably coupled with a tundish. The flow path is formed inside the main body. A molten steel ejection hole is formed in one or more areas of the main body, so that molten steel flows out through a flow path. The top width(112) of the molten steel ejection hole is narrower than the bottom width(111).
