Title: Tundish upper nozzle
Inventor: YOTAWAKE TOMOHIRO
IPC: B22D11/10
Filed: 1994-03-24
Abstract: PURPOSE:To more effectively spout supplied gas into molten steel flow by preventing gas leakage from occurring between a porous refractory and an iron shell, in the tundish upper nozzle. CONSTITUTION:In the tundish upper nozzle having a gas blowing function, the outer periphery of the main body is surrounded with the iron shell 2a, and upper and lower porous refractories 1a, 1b are freely set to the gas blowing position in the inner part of the main body. Respective outer peripheral surfaces of the refractories 1a, 1b are covered with the iron shell through gas pools arranged independently and directly connected to each gas introducing pipe and the part between the outer peripheral part and the iron shell 2a is closely filled with castable refractories 4. By this method, the gas leakage at the time of operation can effectively be prevented and then, the introduced gas is efficiently spouted into a nozzle hole and as a result, the lowering of the back pressure in the upper nozzle during operation is prevented. Further, since inclusion of Al2O3, etc., can effectively be removed, the development of the nozzle clogging can effectively be prevented.
