To develop the combustion characteristics of aluminum powder in steam, the ignition and combustion process of aluminum powder with different additives (KBH4, ammonium perchlorate (AP) and NaCl) addition at different levels were studied using a transparent pipe furnace. The temperature variation of these samples was measured using a thermocouple, and a high-speed camera was used to record combus...

Lalić, Faculty of Technical Sciences, University of Novi Sad, Novi Sad, Serbia This paper discusses the distribution fl ow of aluminum (Al) alloy pipes, starting with the completion of the manufacturing process and fi nal inspection. The proposed solution considers the use of bar-coded caps produced from recycled polymer materials that are placed o...

This paper is concerned with optimization of process parameters for a roller leveller that is an indispensable equipment to eliminate the undesirable curvature of a thin-walled aluminum pipe. Optimization of process parameters has been carried out for a multistaggered-type 14-roller leveller. A finite element model of a multi-staggered 14-roller leveller was constructed for analysis whose resul...
