Ferrous scrap preheating system: Phase 3, Final report
Utilizing electric arc smelters for making steel has allowed many smaller manufacturers to compete with large integrated mills. The electric arc furnace melts scrap to produce steel. The subject of this report is a Scrap Preheater that heats and cleans the arc furnace scrap using its own low cost natural gas energy supply. Scrap preheating can increase the capacity of a given arc furnace and reduce the operating costs. In addition it reduces the air emissions and allows utilization of lower cost scrap. The program was divided into three phases and was to culminate with an operating prototype at a demonstration host site steel mill. A host site agreement was executed and critical components were tested. The prototype scrap preheater was completely designed. It was sized to preheat 30 tons of scrap in a scrap bucket in 30 minutes. Energy is supplied by a rich fume reactor that completely oxidizes organics from the scrap and auxiliary natural gas. There were several delays and changes in the project that resulted in the host site requesting to withdraw from the program. Extensive efforts were made to secure a replacement host site. However, when another host could not be found, the project was terminated.
