Influence of adding iron-steel waste materials on hot metal quality
MetadataShow full item record
Hazardous waste materials, notably industrial ones, are of particular concern, inasmuch as if they are not dealt with adequately, they may pose a serious threat to the environment. In this connection, those industries which develop reuse and/or recycling policies for their wastes in their own manufacturing processes, next to addressing the environmental issue, will, to some degree, be replacing their waste generation by co-products. Further, the gain will be even more substantial if reuse is followed by a lower energy and/or feedstock consumption. This paper looks into the behavior of some waste materials from the iron-steel industry, such as BOF fine sludge, rolling scale and iron oxide stemming from the Acid Regeneration Plant (ARP), aimed at their recycling as treatment agents to pre-refine hot metal. Lab tests suggested that such waste materials from the iron-steel industry may be used as ancillary agents to pre-refine hot metal. However, since lab test results are not absolute, industrial trials are being conducted and the preliminary results are quite promising.
