Aluminium is the world’s second most-used metal after steel and the aluminium production industry is the largest, in volume of metal produced, in non-ferrous metal industry. In this study, results of the material flows (country and global scales) related to the production and use of aluminium and energy consumption in 1980 to 2012 were separately analysed. Also, overview of the current status o...

Abstract Metal powders for the laser powder bed fusion process are usually produced via gas atomization. However, due to tight particle size distribution required this application, yield of atomization is low, resulting in a high-powder cost. In work, parameters were varied increase gas-to-metal ratio reduce produced, and therefore process. As result, eight starting from scrap AISI 136L materia...

In the BOF steelmaking process, lime quality and quantity directly affect slag quality, affecting metallurgical results, liquid metal yield, productivity, therefore total cost environmental impact of steel production. this paper, a value in use model based on mass balance heat was developed used to evaluate process. The has been successfully validated using data Steel Plant. Then three types wi...

Removing lead from gasoline has resulted in decreases in blood lead levels in most of the world, but blood lead levels remain elevated in low and middle-income countries compared to more developed countries. Several reasons for this difference have been investigated, but few studies have examined the potential contribution from locally-made aluminum cookware. In a previous study of cookware fro...

The zinc protoporphyrin/haemoglobin (ZPP/Hb) ratio was measured in the field with a haematofluorometer. A significant increase in ZPP/Hb ratio with advancing age was found in 1295 men who denied any excess exposure to lead. Ninety-seven per cent of the results were below 110 mumol ZPP/mol Hb(Fe) (4.4 microgram ZPP/g Hb). The ZPP/Hb ratio was determined in a lead-exposed population of 2275 men, ...

The issue of automobile recyclability is a problem with complex ramifications for car makers world-wide. Confronted with increasingly stringent fuel economy, emissions, and safety standards, recyclability is an attribute which can limit the ability of the automaker to meet these other goals economically. Nevertheless, social and political pressures upon the industry require that it responds to ...
