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...

Early stage oxidation behavior of SiSiC cellular lattices with different cell types was studied at 1400 °C in two different environments: a porous burner and an electric furnace with stagnant air. Oxidation and silicon alloy bead formation were observed and identified as the most important factors affecting the integrity of the structures. Lowmelting temperature silicon-based alloys formed from...

LiNbO a crystal has excellent electro-optical and non-linear optical properties [1, 2]. However local fluctuations of the refractive index and light scattering centers prevent a wider application of this material in optical devices. Since sub-grain boundaries seem to cause such inconvenience, the production of sub-grain free LiNbO a crystals is strongly required. Various properties of molten L ...

The slagging and fouling characteristics of the heat recovery steam generator (HRSG) for ferrosilicon electric furnaces are discussed in this paper. Three ash samples were taken from the HRSG of a ferrosilicon furnace in Ningxia Province, China, which suffered from serious slagging and fouling. X-ray fluorescence (XRF), X-ray powder diffraction (XRD) and scanning electron microscope (SEM) were ...

The ternary antimonides RE4T7Sb6 (RE = Gd–Lu; T = Ru, Rh) have been synthesized from the elements by arc-melting and subsequent annealing in an induction furnace. The samples have been characterized by powder X-ray diffraction. Four structures were refined on the basis of single-crystal X-ray diffractometer data: U4Re7Si6 type, space group Im3̄m with a = 862.9(2) pm, wR2 = 0.0296, 163 F2 values ...
