In this paper we proposed a modeling method of the electrode lift controlling plant of a n ultra high power electric furnace and verified the accuracy of the proposed model by simulation an d field test. Keyword: ultra high power (UHP) electric furnace, electric lift device, electric lift control

A considerable amount of mill scale is generated from steelmaking plants annually. Although some industries use it as raw material however, since it contains iron in the form of FeO, Fe2O3, and Fe3O4, it can be considered as a valuable metallurgical raw material for iron and steelmaking industry as well. Thus, the aim of this study was to evaluate the possibility, efficiency, and consequences o...

Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

In electric arc furnace steelmaking units, the essential parameters are reducing price, increasing production and decreasing environmental pollution. Electric arc furnaces are the largest users of electric energy in industry. The most important techniques that can be used to reduce the electric energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot ch...

It has been known that a high-emissivity furnace provides an energy-efficient alternative to a conventional furnace [1,2]. To improve the efficiency of a furnace, ceramic coatings with high emissivity are often applied to the interior of the furnace. The purpose of this paper is to show the amount of electrical energy-saving achieved by emissive carbon coating for a tubular vacuum-furnace. Alum...

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...

Power quality is becoming a more concern of today’s power system engineer due to rapid growth of non-linear loads in distribution network. Electrical Arc Furnace (EAF) is one of the responsible causes for deteriorating power quality in the distribution network. Hence electric arc furnace model is needed to study and to analyze the power quality in the distribution network. This paper presents a...

steel slags are the by products of steel industries, which forms during reduction process of iron melting. the chemical composition of it changes depending to the melting procedure. its mineralogical composition also varies based on the cooling procedure. two different types of steel slag were used as absorbing bed for various concentrations of pb2+ ions in the form of lead chloride, and the co...
