The Impact

The processing and recycling experiments of dust from Electric Arc Furnace (EAF) in industrial conditions aimed at highlighting the minimizing possibility of this waste by transforming it into a by-product that can represent either a secondary raw material for steel making in EAF or to recover iron, zinc and lead (the Waltz process). Electric-arc furnace dust (EAFD) is a by-product of steel production and recycling. This fine-grained material contains high amounts of zinc and iron as well as significant amounts of potentially toxic elements such as lead, cadmium and chromium. Therefore, the treatment and stabilization of this industrial residue is necessary. Leaching test is a method of evaluating the impact of waste that is stored (soil, water table).

Industrial Energy

Chemical exergy is equal to the maximum amount of work obtainable when the substance is brought from the environmental state to the dead state by a process involving heat transfer and exchange of substances only with the environment. As it is well known the iron and steel industry is the largest industrial energy consumer. After the employee costs, energy costs (about 30% of the total) represent the second highest cost element in integrated steel works. In this study, the chemical exergy potential in an electric arc furnace (EAF) is calculated and these potentials are distributed depending on production materials, emphasizing the chemical exergy concept.

Control Designs

Production cost in steel industry is a challenge issue and energy optimization is an important part. This paper proposes an optimal control design aiming at minimizing the production cost of the electric arc furnace steel making. In particular, it is shown that with the structure of an electric arc furnace, the production cost which is a linear programming problem can be solved by the tools of linear quadratic regulation control design that not only provides an optimal solution but also is in a feedback form. Modeling and control designs are validated by the actual production data sets.

A technology of Р6М5 steel-making by the method of remelting with oxygen blowing in electric arc furnace of capacity 20 t has been examined. To improve technical and economic characteristics of the furnace operation for a series of experimental-industrial melts a number of measures was proven. The measures resulted in a decrease in melt time, a reduction of melting loss and specific consumption of energy and oxygen.

Furnace Slag

This work investigated the reduction of chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS) and the concentration of heavy metals of wastewater from a steel making plant. Adsorption experiments were carried out by electric arc furnace slag (EAFS) in a fixed-bed column mode. The raw wastewater did not meet the standard B limitations, having high values of BOD, COD, TSS, Iron, Zinc, Manganese and Copper. After passing through the fixed bed column, BOD, COD and TSS values decreased to 1.6, 6.3 and <2 mgL-1, respectively while the concentration of Iron, Zinc, Manganese and Copper were 0.08, 0.01, 0.03 and 0.07 mgL-1, respectively. The results confirmed that EAFS can be used as an efficient adsorbent for producing treated water that comply with the Standard B limitations for an industrial effluent.
