EXPERIMENTAL ANALYSIS OF THE ALUMINUM COLD ROLLING PRODUCTION PROCESS: A CASE STUDY ON THE 1050 H0 ALLOY

The paper deals with the investigation of the production process of aluminum and delves into the intricate technological production chain associated with aluminum, with a specific focus on the crucial cold rolling process utilized in the fabrication of aluminum coils. Using rigorous experimental analysis, the study thoroughly evaluates the distinct stages involved in the cold rolling procedure, giving particular attention to the esteemed and distinctive 1050 alloy of aluminum. The study thoroughly addresses the process of achieving the desired mechanical properties of aluminum, encompassing both theoretical and experimental investigations. First, a theoretical framework is established to understand the underlying principles governing the chemical and physical properties of aluminum. The laboratory analysis focuses on the main technological advancements involved in the hot rolling process of an aluminum coil with dimensions measuring 6.60*1660 mm. The objective of this process is to achieve conformity with the 0.30*1500 mm H0 standard. The mechanical properties of a material obtained through experimental part involving metal cold rolling and thermal processing processes are as follows: a tensile strength (Rm) of 84 MPa, a yield strength (Rp) of 42 MPa, and an elongation of 28%. The material composition consists of 99.59% Al, 0.223% Fe, 0.128% Si, and 0.059% other trace elements. The meticulous research conducted significantly contributes to the current understanding of the aluminum cold rolling production process.
