Abstract
338,535. Fletcher, J. E. Aug. 19, 1929. Extracting.-In a process for the direct production of cast iron, the ore &c. is reduced in one or more primary rotary furnaces and the molten product is passed thence into a secondary furnace in which it is further heated along with any accompanying slag and its composition modified as desired by the addition of refining or alloying materials. The Provisional Specification is not limited to the production of cast iron but refers to the reduction of metals generally.
