Zusammenfassung:A description is given of a process for producing agglomerates composed of finely particulate iron carriers and at least one binder as starting material for a metallurgical process. The agglomerates are, in at least one further agglomeration step, coated with a layer consisting of iron carriers and at least one binder and heated in such a way that only the binder in the region of the surface of the agglomerates is cured. In a process for producing liquid pig iron or liquid steel raw products from starting materials and if appropriate additives and agglomerates, the agglomerates are preheated in a reduction zone which has a preheating stage in such a way that the agglomerates cure fully in the preheating stage.
