Método de produção de briquetas contendo ferro moldadas a frio

摘要

When cold-moulded (cold-pressed) briquettes are produced from iron-containing metallurgical waste material admixed with binder, in order to achieve high mechanical strength of the briquettes and to obtain virtually complete reducibility, magnetitic metallurgical waste material such as scale (tinder) (1) is mixed with haematitic fines (5) to form a layer (10) which envelops the individual magnetitic particles (9) and consists of the haematitic fines (5), after which the binder is then admixed (Figure 1).
