Analysis of Cooking Utensils Containing Aluminium Scrap in Senegal
並列摘要
The purpose of this study is to analyze the metallurgical quality cooking utensils containing aluminum scrap in Senegal. Indeed, in this country, the recycling of metallic materials is a very interesting income generating activity. A whole chain, from collection to revaluation, has been set up and operate this vein with the support of partners, for the most foreigners. For aluminum scrap mostly issued from the automotive industry, they are essentially recycled in cooking utensils by the technique of molding sand. A study was then proposed to analyze the reconstituted aluminum alloy, the artisan technique and the quality of final products. This first part focuses on the quality of alloys and their mechanical properties. The results show that all the alloys have levels higher than the maximum allowed by the standard NF EN 601 (July 2004). They also proven that the finished products have a high porosity due to the low amount of water control and linked to the quality of sand. That's why our analysis allowed to propose a change in preventive than half of the sand every three (03) months.
