Recycling of EAF dust into the EAF especially from high alloy steelmaking
Revue de Métallurgie, 2002In Europe about 600,000 tons of dusts are generated in EAF steelmaking. Valuable metals like zinc, lead, chromium and nickel are recovered from these dusts by external processors, usually. In the past, only few attempts on internal recycling have been made.

Consteel© EAF and conventional EAF: a comparison in maintenance practices
2010The present paper highlights the main differences between Consteel® and conventional EAF technologiesregarding scheduled and unscheduled maintenance practices. The study has been made on the basis of datacollected in plants with high maintenance standards and more than 10 years of operational experience.These data have been analyzed and organized in a ...

In the electric arc furnace (EAF) process, the use of coal plays a major part in the control of the descent of the scrap charge, in the efficiency of heat transfer to the charge and in the metallurgical treatment of the liquid bath. In order to increase the efficiency and the amount of coal in the EAF, several technologies have been developed in France

Modeling and simulation of EAF melt shop
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000The paper describes modelling and simulation of electric arc furnace (EAF) melting shop. This is a batch process and can be classified as a hybrid system in which discrete events such as material transportation operations and sequencing of the power supply to the furnace are combined with the continuous time melting of steel. The continuous part of the

Multivariate process monitoring of EAFs
Ironmaking and Steelmaking, 2005The application of a multivariate statistical process control (MSPC) to an EAF and the benefits that can be delivered was discussed. Several statistical methods for multivariate prediction were tested such as multiple linear regression (MLR), principal component regression (PCR) and partial least squares (PLS).

The Expeditionary Aerospace Force (EAF) Concept presents a severe challenge to the test community. ATE Systems included in the support structure of this new concept must exhibit characteristics seldom if ever seen before. This paper will attempt to predict what characteristics such a forward-looking ATE system must possess It will focus on the critical

The dynamic self-adjusting EAF
Ironmaking & Steelmaking, 2005Current practice in electric steelmaking has been to control melting within the furnace on the basis of predefined parameters, modified to a limited extent by online feedback employing process data. This use of what are essentially static meltdown profiles to control a dynamic process limits the operator's ability to respond to variations during ...

Mitigation of EAF Induced Problems
2006 IEEE PES Power Systems Conference and Exposition, 2006Electrical arc furnaces (EAF) are commonly employed in industry to produce molten steel by melting iron and scrap steel. EAF can be a source of power quality problems and a potential threat to nearby generators. In this paper, the power quality problems induced by a 40 MVA EAF located in the Tennessee power system solved by FACTS and energy storage ...

The EAF Slag as Construction Material
Materials Science Forum, 2007The metallurgical slag is a normal building material in Europe but not in Hungary. I prove by my own researches that the electric arc furnace slag isn’t harmful to the nature especially the ground water and their physical aspects are similar to the natural rocks.

Energy Efficiency Criteria of EAFs
2009Methods for evaluating energy efficiency of innovations for EAFs. Difficulties associated with the quantitative determination of EAFs’ energy efficiency in connection with the joint utilization of different energy sources. Non-promising of attempts to estimate this value by a certain common single coefficient.
