<p>PURPOSE: A refractory brick for float bath and a manufacturing method thereof are provided to improve corrosion resistance and lower hydrogen diffusivity by oxide coating a surface. CONSTITUTION: A refractory brick for float bath(110) includes oxide-coating layer(111) in upper side which is in contact with molten metal(M). The refractory brick for float bath includes the oxide-coating layer in bottom side. The oxide is zirconia and the oxide-coating layer is coated with thermal spray method. A thickness of the oxide-coating layer is 0.1-1mm and porosity is 1% or less. A manufacturing method of refractory brick for float bath comprises a step of oxide-coating upper side of the refractory brick which is in contact with molten metal.</p> |
