Mill scale recycling by SHS metallurgy for production of cast ferrosilicon and ferrosilicoaluminium

Abstract

The possibility of utilizing the industrial wastes of metallurgical production and secondary raw materials (aluminum) by organizing self-propagating high-temperature synthesis (SHS) and obtaining cast ferroalloys (Fe?Si; Fe-Si-Al, and Fe-Si-Al(Cr, Mn)) was investigated. The main production operations of the preliminary preparation of the starting raw materials were worked out and cast ferroalloys providing high concentration Si, Al and B were revealed. The possibility of processing the industrial wastes of metallurgical production and obtaining cast ferroalloys was shown.
