Abstract

162,618. Koppers, H. April 28, 1920, [Convention date]. Drawings to Specification. Purifying and refining.-In a process for desulphurising iron and steel, the iron bath is freed in the usual manner from phosphorus, manganese &c. and the slag layer is removed and replaced by a new layer of highly basic slag into which carbon, having approximately the same specific gravity of the slag, is immersed for the purpose of converting in a neutral atmosphere the sulphur into calcium sulphide and at the same time removing the last traoes of oxygen in the form of carbon monoxide. The carbon is prepared by overheating coke, drying and burning, grinding finely and mixing it with tar, the mixture being formed under great pressure into blocks provided in some cases with perforations. When required the slag bath is regenerated, after the molten iron has been removed, by passing a current of air over or through the slag.
