The results of observation steelmaking oxidation stage at EAF-135 were analyzed with automated control system the electrical characteristics. There are three main zones in furnace working space, which differ by aggregate state materials them: arc discharge, melt and foamed slag. distribution data electric power over is given. active powers asymmetry arcs under single electrodes affected short n...

As a result of the depletion high-grade manganese reserves, it has become necessary to consider exploitation low-grade ores. The main problem ore is low Mn/Fe ratio, which makes unfit for production ferroalloys. In this work, selective reduction technique was used smelting low-manganese in presence coke and fluxing material an electric submerged arc furnace obtain rich slag pig iron. product bl...

The use of electric arc furnace slag (EAFS) as sole precursor to produce alkali-activated mortars has been experimentally investigated. EAFS, a by-product the steel recycling industry, is coarse material with unevenly distributed and size-extensive particles. Milling EAFS was required achieve cement-like sized powder before it could be used precursor. Different combinations sodium hydroxide (Na...

Wear and corrosion has always had an adverse effect on the performance and service life of electrical arc furnaces. Every year, large amounts of money are spent on replacing the worn out parts of these furnaces which are no longer usable because of corrosion. One of the key causes of corrosion in electrical arc furnaces is the thermal radiation from the arcs. If the arcs are not properly covere...
