Abstract

The paper presents the research on and the results related to the use of briquetted wastes, particularly small size and powdery ferrous ones. In order to produce the briquettes, we used scales and steel plant slag as small-grain ferrous materials, and electric steel plant dust, blast furnace-agglomeration slag and red slime from the alumina plants as powdery ferrous wastes. The research aimed at establishing recipes so that the contents of carbon may grant, on the one hand, the advanced reduction of iron oxides in the process of briquette hardening and on the other hand, high values of fissuring and crushing resistance.

Keywords

blast furnace dust; briquettes; crushing time lag; scales; steel plant dust; resistance to crushing; resistance to fissuring
