Abstract

See full text

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.
