This article presents the main constructive and functional modernization of Electric Arc Furnace (EAF). Schwabe is creator UHP (Ultra High Power) EAF. We present in this optimal use EAF power time aspects. These two factors determine increase productivity Furnace. arc furnace operation can be based on either short (with high intensity low voltage) or long version voltage). Introduction vault walls water cooled has resulted major reductions consumption refractory bricks from electric furnace....
In this paper we present the results of industrial experiments consisted in determination, by specialized measurements, dust percentage evacuated gases from EAF and chemical composition polluting burnt gases. The electric arc furnaces (EAFs), as powerful energy consumers, are also emissions generators with an important environmental impact. steel refining is based on a complex mechanism oxidizing processes, due to introduced oxygen air. A first step diffusion adsorption slag surface...
The development of aluminum matrix composites (AMCs) reinforced with ZrB2 particles represents a significant advancement in materials engineering, combining lightweight properties exceptional mechanical. This paper presents comprehensive study on the in-situ fabrication AA6063/ZrB2 composites, exploring material properties, and potential industrial applications. By employing reaction techniques, are synthesized directly within an alloy matrix, resulting strong interfacial bond uniform...
The paper’s aim is to present the processing of a new master alloy similar STROBLOY. This represents combination two alloys, already known in aluminum industry (AlTiB and AlSr). benefits this are cut Ti, B Sr consumption, as well grain refining/modification ecological technology for Al-Si Al-Mg-Si alloys. So, was obtained from binary AlB8, AlSr10 AlTi10 alloys melted an electric resistance furnace argon atmosphere. Samples were cast iron mould. As STROBLOY, quaternary contains fast...
The aim of the paper is to present influence a new multifunctional material, master alloy named Al-Sr-Ti-B, in aluminum foundry alloys. Al-Sr-Ti-B represents combination two alloys, already known industry, AlTiB and AlSr, used treatment alloys for grain refining modification. As Strobloy, our contain fast dissolving SrAl4 particles also nucleating as TiB2 (Al,Ti)B2 which are important first modification second presents optic electron microscopy studies realized on AlSi7Mg treated with this material
"Aluminum complex alloy AlCuMgZn, reinforced by in-situ TiB2 particles are fabricated via liquid metallurgy route based on the exothermic reactions between matrix and inorganic salt mixture (K2TiF6 KBF4), at 750oC, various time (60, 90 120 minutes). The XRD patterns revealed formation of TiB2. At working temperature thermodynamic point view (negative G), some secondary reaction also was possible, AlB12, MgB2 MgB12 can to form. main alloying elements AlCuMgZn do not influence final products....
This paper aims to present a way of obtaining aluminum based composite material obtained by powder metallurgy technique. We start mixing and milling the powders, compressing sintering samples. established cycle for this type studied samples SEM microscopy. The reaction between matrix precursor reinforcing materials was with aid HSC 4.0 program, available at Engineering Management Metallic Materials department.
Experimental data from electrolytic refining of copper anodes obtained scraps are presented in this paper. Alloying elements behaviour the secondary was studied by SEM microscopy, EDAX chemical characterization, and atomic emission spectroscopy.
