    摘要: A process for producing pig iron or liquid primary steel products in a smelting unit (1), in particular a melter gasifier. Iron-ore-containing charge materials, and possibly additions, are at least partially reduced in at least one reduction unit (R1, R2, R3, R4) by means of a reducing gas. A first fraction of the at least partially reduced charge materials is melted down in the smelting unit (1), while carbon carriers and oxygen-containing gas are supplied, with the simultaneous formation of the reducing gas. The reducing gas is fed to the reduction unit (R1, R2, R3, R4) and, after the reducing gas has passed through the reduction unit, it is drawn off as top gas. A second fraction of the at least partially reduced charge materials is fed to a smelting reduction unit for reducing and smelting.

    摘要: A process for producing agglomerates from fine-grained iron carriers and at least one binder as a charge material for a metallurgical process is shown. In at least one further agglomeration step, the agglomerates are coated with a layer, comprising iron carriers and at least one binder, and heated in such a way that the binder is cured in the region of the surface of the agglomerates. In a process for producing liquid pig iron or liquid primary steel products from charge materials and possibly additions and agglomerates, the agglomerates are preheated in a reducing zone, which has a preheating stage, in such a way that the agglomerates completely harden in the preheating stage.

    摘要: A process and an apparatus for producing liquid pig iron or liquid primary steel products from charge materials formed by iron ores and additions. The charge materials are subjected to a further reduction in a reducing zone (1) and are then fed to a smelting zone or a smelting unit (2), in particular a fusion gasifier, for smelting with the addition of carbon carriers and oxygen-containing gas to form a fixed bed. A CO- and H2-containing reduction gas is formed, which gas is introduced into the reducing zone converted there and drawn off as top gas. The hot top gas, laden with solid matter, after separation of the solids, is subjected at least to a dry coarse separation and at least parts of the hot solids segregated by the separation are returned into the smelting zone or the smelting unit (2) or the reducing unit (1). In addition, the top gas is treated in a further fine separation stage (13A).

    摘要: A method for controlling a transformation process in which the conversion of charge materials to a product takes place along a transformation interface from the crystal and/or grain and/or phase and/or pore surface into the charge material, wherein one or more chemical elements in the charge materials is released and/or incorporated and/or rearranged and wherein the conversion of the charge materials takes place along advancing transformation interfaces. The charge materials are identified on the basis of at least one optical, in particular microscopic, analysis with respect to their phases and/or phase components and/or their phase morphology, structure, texture and/or their chemical composition. On the basis of these variables, reference functions for the charge materials, which describe the conversion of the charge materials in the process, are assigned and used for establishing the process parameters of the transformation process.
