Process and apparatus for the manufacture of steel from iron carbide

Abstract From the Canadian patent

A two stage reaction for the production of steel from iron carbide is carried out in two separate but interrelated reactors (1 36). In the first reactor , (1), iron carbide with slag formers, is fed into a feed end (2) and the reaction is well-mixed by the vessel geometry the stirring action of below-, surface injection of oxygen and iron carbide feed and the evolution of gases , from the liquid metal bath (9). The product containing about 0.5-2 % carbon, is fed into the second reactor (36) where it is refined with subsurfaceinjected oxygen. The second reaction is autogenous and the evolved carbon , monoxide is fed to the first reactor (1) where it is burned with oxygen in a foamy slag, …
