Abstract
In a process of operating for melting and refining steel &c. a non-oxidizing is passed in a closed circuit upwards through a shaft furnace and downwards through a gas-heating stove containing incandescent solid fuel. The furnace may be associated with two stoves, which are blown hot, and used for heating the circulating gas alternately, and where a single stove is used the gases produced during the hot blowing stage are passed to the furnace, in which they are burnt with pure or nearly pure oxygen. The metal melted in the shaft may be refined in a coal-dust fired open-hearth furnace, the products of combustion from which are passed to the shaft. When the process is used for the production of steel from scrap the refining may be effected by oxygen, or by a coal-dust oxygen flame.
