Abstract

Installation for carrying out a process for iron ore iron and steel treatment in which the ore is heated and reduced in a rotary tube furnace by means of solid carbon and flue gas conducted in countercurrent, and the reduced iron accumulates in a first hearth furnace and it is reheated and intermittently transferred to a second hearth furnace, the latter transforming into cast iron, cast iron or steel of the desired composition, characterized in that the chambers of the rotary tube furnace and hearth furnaces are hermetically connected to each other and because only at the loading end of the rotary tube furnace is an outlet for waste gases provided.
