Ferroalloys Processing Equipment
Published in Handbook of Ferroalloys
The process by which ore is converted to a ferroalloy contains a number of steps. These include mining of the ore; preparing the ore by processes such as crushing, screening, washing, grinding, or milling; and sometimes applying beneficiation processes such as flotation, followed by smelting and refining.This chapter describes the equipment used fo...
Fabrication of copper oxide nanofluid using submerged arc nanoparticle synthesis system (SANSS)
Published in Journal of Nanoparticle Research
The optimal parameters are found for preparing nanofluid in our submerged arc nanoparticle synthesis system (SANSS) using a copper electrode. A suspended copper oxide nanofluid is thus produced at the current of 8.5–10 A, voltage of 220 V, pulse duration of 12 μs, and dielectric liquid temperature of 2°C. The CuO nanoparticle are characterized by t...
Comparisons of Solid By-Products Generated from Thermal Plasma Incineration Ash Melting Systems by Plasma Torch and Thre...
Published in Journal of Advanced Oxidation Technologies
Solid waste disposal has become a major concern since there are a limited number of landfill disposal sites. In the past, incineration of solid wastes was considered a solution to the landfill site limitation since solid waste volume can be reduced to 1/6 by conversion to incinerator ash, and heat and electricity recovery from the incineration proc...
The effect of post weld heat treatment on welds in steel structures
The effect of post weld heat treatment (PWHT) on residual stresses, yield strength and toughness as well as on microstructural features of submerged are weld metal was studied with three types of C-Mn-steels. All techniques used for measuring residual stress reduction in PWHT were found insufficient to adequately characterise the stress distributio...
