Abstract

The invention belongs to the field of tundish technology, and discloses a tundish upper nozzle structure and an installation method. The tundish upper nozzle structure includes: an upper nozzle and a nozzle seat brick fixed outside the upper nozzle; the upper nozzle and the The nozzle seat bricks are filled with chrome fire clay, wherein the ratio of chromium material to water in the chromium fire clay is 100:21; the nozzle seat bricks are covered with dense ramming material, wherein, The ratio of dry ramming material to water in the ramming material is 100:4; the upper outer wall of the upper nozzle is set as the first inclined surface inclined to the inner side of the nozzle, and the inner wall of the cylinder cavity of the nozzle seat brick is opened into a second inclined plane bridged with the first inclined plane. The upper nozzle structure of the tundish provided by the present invention can reliably prevent steel seepage.

Description

technical field [0001] The invention relates to the field of tundish technology, in particular to a tundish upper nozzle structure and an installation method thereof. Background technique [0002] Tundish nozzle steel seepage 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 causing serious damage to production. pose a safety hazard. Contents of the invention [0003] The invention provides a tundish upper nozzle structure and an installation method thereof, which solves the technical problem of steel seeping through the tundish nozzle in the prior art. [0004] In order to solve the above technical problems, the present invention provides a tundish upper nozzle structure, comprising: an upper nozzle and a nozzle seat brick fixed outside the upper nozzle; [0005] The gap between the upper nozzl...
