Abstract

The invention belongs to the technical field of tundishes, and discloses a tundish upper nozzle structure and a mounting method thereof. The tundish upper nozzle structure comprises an upper nozzle and a nozzle brick cup fixed outside the upper nozzle; the position between the upper nozzle and the nozzle brick cup is filled with chromium fire clay, wherein the ratio of chromium materials to waterin the chromium fire clay is 100: 21; dense ramming materials are laid outside the nozzle brick cup, wherein the ratio of dry ramming materials to water in the ramming materials is 100: 4; and the outer wall of the upper portion of the upper nozzle is arranged to be a first inclined face inclining towards the inner side of the nozzle, and a second inclined face matching with the first inclined face is arranged on the inner wall of a cylinder cavity of the nozzle brick cup. According to the tundish upper nozzle structure, the steel seepage can be reliably prevented.

Description

technical field [0001] The invention relates to the technical field of tundish, in particular to a tundish upper nozzle structure and an installation method thereof. Background technique [0002] Steel seepage at the tundish nozzle refers to the behavior of molten steel leaking to the lower part of the tundish along the gap between the tundish seat brick and the nozzle during the pouring process, blocking the travel channel of the tundish accident gate and giving production to the tundish. bring security risks. SUMMARY OF THE INVENTION [0003] The invention provides a tundish upper nozzle structure and an installation method thereof, and solves the technical problem of steel infiltration of the tundish nozzle in the prior art. [0004] In order to solve the above technical problems, the present invention provides a tundish nozzle structure, comprising: a nozzle and a nozzle seat brick fixed on the outside of the nozzle; [0005] Chromium fire clay is filled between the ...
