The actual problem of mineral resources depletion in ferrous metallurgy can be effectively solved by complex reuse technogenic waste. That waste is mostly presented EAF (electric arc furnace) slag and LF (ladle slag. These two kinds have no full utilization. residues are going to the dump then locations pollute environment. However, transformed into valuable industrial product interaction compo...

The rapid increase of non-linear loads in the last three decades has caused electrical quantities such as voltages and currents in 3-phase distribution systems to become distorted waveforms. This paper reviews, explains and discusses some new concepts, definitions and new available theory in the unbalanced and distorted systems. The usefulness of the proposed practical definitions is investigat...

The new silicide NbPdSi was prepared by melting the elements in an arc-furnace. Well-shaped single crystals were obtained by annealing the sample in an induction furnace. The structure of NbPdSi has been studied by X-ray powder and single crystal diffractometer data: TiNiSi type, Pnma, Z = 4, a= 643.0(1), b= 376.7(1), c= 744.4(2) pm, wR2= 0.0330, 346 F2 values, and 20 variables. The palladium a...

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...

Powderous crystalline materials of the composition Fe3−xMnxC have been prepared by first synthesizing Fe3C via mechanical alloying in a planetary mill followed by the addition of elemental manganese and arc-plasma melting or via the classic ceramic route in an electric furnace. The milling time for the synthesis of Fe3C was significantly reduced through adjusting the parameters of the planetary...
