Abstract
A method and apparatus for making steel in a basic oxygen furnace installation, in which water is sprayed from a central location within and at the open end of an exhaust hood 12 outwardly toward the inside hood surface to cool the hood and wet the off-gases during a blow. A ring-like spray manifold 22 is supported on an oxygen lance 14 for automatic insertion to the proper location in the hood, for removal with the lance, and for automatic operation concurrently with the supplying of oxygen.
