Abstract

The invention relates to a method and a device for introducing fine particle shaped material (4) comprising ferritic particles into an fluidised bed reduction unit (1) having an fluidised bed (24) wherein the temperature in the fluidised bed (24) is greater than 300°C preferably greater than 400°C particularly preferably greater than 500°C and less than 900°C preferably less than 850°C particularly preferably less than 800°C and wherein the fine particle shaped material (4) is introduced directly into the fluidised bed (24) and/or in a free space (25) above the fluidised bed (24) by means of a burner (2). The invention further relates to the use of the method according to the invention for producing liquid pig iron (17) or liquid steel pre products (18) by means of a melt reduction process in a melt reduction unit (22).
