Electric arc furnace dust, due to steel fabrication by-products, some of that material has been contaminated with radioactive materials from orphan sources. After calculating the concentration radionuclide activity, it is known meets criteria for clearance application and can be used other purposes according appropriate characteristics. By determining clearance, EAF dust will processed through ...

This paper provides results from a series of projects investigating the application of PLS to provide process engineering solutions in the steel industry. These applications involve the prediction of final product quality in a LD converter, the prediction of NOx in a reheating furnace and an analysis of the effects that changing scrap types have on final product quality in an electric arc furna...

Considerable work has been done on the development of advanced process control for the Electric Arc Furnace (EAF) steelmaking process. Historically, many control systems have been employed which rely on static heat balance calculations coupled with power input profiles to generate recipe driven control models. Steelmakers have desired to have continuous information about the gases exiting the f...
