Abstract

In the iron and steel enterprises, the sintering process and sintering plant are the best paths for waste recycling. Any type of ferruginous waste generated as a byproduct of the different stages of steel production could be used in this way. In order to use the ferruginous mud resources scientifically and rationally, the experimental studies and a pilot industrial test for different ferruginous mud mixture ratios and different carbon proportions are conducted on basis of physical and chemical properties control of ferruginous mud. Test results show that use of ferruginous mud with higher levels of substances requisite in the sintering production, such as CaO and C, helps to reduce the cost of sintering ore, however, its fine granularity is detrimental to the sintering permeability. The indexes of yield and quality of sinter decrease with increasing carbon content of ferruginous mud, when it entirely substitutes carbon from sintering fuel. On the other hand, when 1/3 of the carbon content is provided by ferruginous mud instead of sintering fuel, sintering quality is close to the baseline values. The theoretical foundation and technical basis for higher efficiency of sintering using ferruginous mud are offered.
