The sealing concave rings and the sealing flanges can be arranged in a plurality of groups in a concentric ring shape.
The upper sealing layer and the lower sealing layer are made of high-temperature-resistant fire clay.
The upper brick cup, the fixed brick and the lower brick cup are carbon-free jade blocks.
Compared with the prior art, the utility model discloses following beneficial technological effect has:
the utility model discloses improve traditional integrated into one piece's brick cup into split type, including last brick cup, fixed brick and lower brick cup, can partly install one by one during the installation, can local maintenance when maintenance and change. The upper brick cup, the fixed brick and the lower brick cup are sealed through the sealing layers, and the steel leakage of a connecting gap is prevented. The upper brick cup, the fixed brick and the lower brick cup are carbon-free jade blocks, so that the brick cup is more air-permeable. The side wall of the lower channel is a convex slow flow arc, molten steel flows out from a side hole at the bottom of the water gap in a jet flow mode, and the molten steel flows into the tundish through the slow flow arc in a slow flow mode without directly impacting the tundish downwards and causing molten steel turbulence and splashing.
