Method of and apparatus for hot dip coating of steel strip |
摘要 |
An improved method of and apparatus for hot dip metal coating of steel strip in which the strip is heated and cleaned in a furnace then passed through a protective hood containing a reducing gas and into the molten coating metal bath. Coating metal oxides evolved in the hood are removed by flowing a nonoxidizing gas across the surface of the coating metal in the hood and withdrawing the gas and entrained oxides from a location in the vicinity of the coating metal surface. The oxides are removed from the withdrawn gas, and the gas returned to be again flowed across the coating metal surface.
