The Agglomeration of Solid Wastes for Ferroalloy Production

Abstract

There is huge number of solid wastes produced from Ferroalloy production processes. The solid wastes are crushed raw materials fines during transportation, slags and the fines from the dust collector. Recycling of these solid wastes could obtain resource, environmental and economic benefits. Agglomeration of the wastes and put them back into the submerged arc furnaces is one of the several optimal methods to reuse it. In this study, a preliminary study of the agglomeration of the wastes for FeSi process is presented. The key influence factors, for example, the way of agglomeration, components, binder type and content for different agglomerates were investigated. Compressive strength, thermal strength and drop strength of the briquettes were tested. The results show that the mixed binder can achieve the strength requirements of the briquettes in cold state and high temperature in industry.
