trials with enhanced efficiency

摘要

The invention relates to a method for increasing the effectiveness of the smelting reduction of oxidic metal carriers, particularly iron ore, and improving the heat efficiency of the charged fuels in the smelting reduction process which takes place in a reaction vessel containing a molten bath with a layer of slag and wherein the reaction gases escaping from the molten bath are afterburned with oxidizing gases, the resulting heat is transferred to the molten bath and the reacting agents, ore and carbon, are fed to the smelt at least partly from the top through the gas space of the reaction vessel, wherein these reacting agents, ore and carbon, are added in a compact form to the molten bath as a composite material with or without further escort substances.
