Abstract

A brief description of a new process for recycling hot electric steelmaking wastes of high iron oxides content, from ministeel mills that produce common and special steels is made. The new process is designed to get the best treatment cost for the residues recycling. It is based in the application of the principles of technologies experienced in ministeel industries. This is possible because the following improvements are obtained: a) obtention of a commercial product of high zinc oxide content; b) avoidance of new toxic wastes; c) use of low cost process energy; d) increase of metallic yield in the residues; and e) treatment of residues in the mill ("in situ"), or from other ministeel mill ("off site"). Previous technologies precedents of the new process, are given and a comparative study between the new recycling process and the same recycling process without heating pretreatment using the same furnace is made.
