Advanced Technology for Recycling and Reducing Waste Materials at the Steel Industry

摘要

Steel manufacturers can contribute to the establishment of a recycling-oriented society by recycling iron materials, utilizing recycled resources by taking advantage of the existing infrastructures, and using technologies to eliminate hazardous emissions. It is particularly worthy to note that the present steel manufacturing process has the potential to form a social infrastructure characterized by safety, reliability and high efficiency in the effective utilization of waste substances when deregulation is enforced. More concretely, with the techniques related to high-temperature fusion treatment using blast furnaces, converters, and electric furnaces serving as platforms along with designs for iron manufacturing equipment and operation techniques cultivated thus far, fusion of the application of those techniques into an appropriate interface technology that best utilizes of them can be considered.
