連続鋳造用浸漬ノズル
Document Type and Number:
Japanese Patent JP2008540131
Kind Code:
A
Abstract:
The present invention relates to a submerged entry nozzle for continuous casting, and more particularly, to a submerged entry nozzle (100) for continuous casting, in which a section of a portion of a nozzle is formed to have a flower pattern (103) for preventing molten steel passing through the submerged entry nozzle (100) from flowing unevenly, and inclusions from attaching to the submerged entry nozzle. The submerged entry nozzle (100) for continuous casting, having a flower patterned portion (B) with a flower pattern (103) of radial circular recesses at a portion of the nozzle for preventing molten steel from flowing unevenly and inclusions from attaching during the molten steel passes through the nozzle in continuous casting, including an enlarged inside diameter portion (C) having an inside diameter 1.1 1.5 times greater than an inside diameter of a circle drawn to pass through innermost tips of the flower pattern (103), wherein the enlarged inside diameter portion (C) begins from an end of the flower patterned portion (B) which is spaced a predetermined distance away from a top of the nozzle, thereby preventing the molten steel from flowing unevenly and inclusions from attaching to an inside of the nozzle, enhancing productivity of the continuous casting and stabilizing a surface of the molten steel in a mold to improve a quality of steel.
