Synopsis-In this research, possible usage of EAF dust on cement is investigated. Therefore, effects of addition of different percentages of EAF dust on the most important properties of cement such as hydration heat, water coefficient, viscosity, initial and final setting times, strength development and leachability of heavy metals were studied. Results showed that EAF dust alters the characteri...

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...

This investigation develops a revisable method for estimating the estimate value of equivalent 10 Hz voltage flicker (DV10) of a DC Electric Arc Furnace (EAF). This study also discusses three 161kV DC EAFs by field measurement, with those results indicating that the estimated DV10 value is significantly smaller than the survey value. The key point is that the conventional means of estimating DV...
