2018 Chinese Factory Top Quality Upper Nozzle Brick For Steel Ladle
Description:
Upper Nozzle Brick is a refractory steel water flow outlet embedded in the bottom block of shenggang barrel.When not pouring, the nozzle brick and plug brick are in line contact to ensure no steel leakage.The upper part of the brick is an arc shape, which is convenient for opening and closing the nozzle and reducing the resistance of steel water flow. The lower part is a straight section to stabilize the injection flow.
Application:
Upper Nozzle is used in the process of steel casting, widely used in large ladle, middle ladle and small ladle.
Features:
Excellent thermal shock resistance
High strength at high temperature,
Excellent resistance to erosion
Good resistance to rushing scour.
Low rough degree after slide surface is used
Low fissure expansion coefficient
