Abstract

163,561. Vermaes, S. J., and Syndicaat Electro-Staal. March 30, 1920. No Patent granted (Sealing fee not paid). Extracting.-Iron in finely grained condition is heated directly up to 1100‹ C. or higher, for example in a rotary kiln, and then transferred to a reduction furnace indirectly heated. Fluxes may be added before preheating or may be separately heated and mixed in the reduction furnace, to which is also added carbon or coal as required for complete reduction of the ore. The temperature is maintained above 1000‹ C. but below the melting-point of iron. The solid, sintered mass of iron formed is discharged, without admission of air, into another furnace where it is melted and slag removed; the iron may be further purified and carbonized in another smelting-furnace. A part of the gases liberated in the reduction furnace and consisting of carbon monoxide (and hydrogen and hydrocarbons if the fuel is coal) is burnt in the heating-channels of the reduction furnace, a second part is used for heating the smelting-furnace, and a third part may be used for pre-heating the ore and fluxes by direct contact with the combustion products.
