Abstract

The invention relates to a method for producing molten material, wherein oxygen, reducing agents and iron that has been reduced in a reduction reactor (1) are introduced into a melter gasifier (3). The reducing agent is gasified with the oxygen and the heat thereby produced melts the reduced iron. The coupling gas from the melter gasifier (3) is used at least as a portion of the reduction gas, reacted top gas is withdrawn from the reduction reactor (1). The aim of the invention is to increase energy efficiency and raw material efficiency as well as productivity while at the same time obtaining metallurgically improved properties of the product. For this purpose, at least a portion of the top gas is branched off from the line (9) for the withdrawal of the top gas from the reduction reactor (1) and is returned via at least one return line (13, 18) leading to the melter gasifier (3) and is introduced into the melter gasifier (3).
