ユの上ノズル構造。 A gas pool is formed between the upper nozzle refractory for injecting molten steel provided at the bottom of the tundish and the steel hoop, and the upper nozzle refractory is divided into upper and lower stages with gas injection thin tubes penetrating from the outer circumference to the inner circumference. The inside of the gas pool is partitioned into a plurality of upper and lower parts by a sealing ring for each stage of the gas blowing thin tube, and each of the gas pools partitioned into the plurality of upper and lower parts is connected to the gas pool through the steel hoop. An upper nozzle structure of a tundish for continuous casting, characterized in that the upper nozzle structure of a tundish for continuous casting is formed by connecting gas inlet pipes each independently controlling the gas flow rate.
