PROCESSING OF ALUMINUM CAN WASTE INTO LOW DUTY RODS AND WIRE WITHOUT REMELTING
Problem Statement (Relevance): The paper describes a key point and features of processing of bulk crushed aluminum can waste into rods and wire of various diameters, completely excluding their remelting. Such approach leads to a significant yield gain and energy cost reduction for the main operations of waste processing. Objectives: To draw out and practically test a basic process flow diagram for manufacturing semi-finished products from bulk aluminum can waste, and study step by step a pattern of changes in mechanical characteristics. Methods Applied: When introducing the suggested diagram, the authors applied the techniques and methods used in related areas of industrial production connected with powder metallurgy and metal forming. Originality: The obtained data can be considered relatively new, as until quite recently metal waste under study in the paper was disposed and returned to production, as a rule, by preliminary baling and subsequent remelting. Findings: The paper shows the possibility of producing bar and wire products from aluminum-based secondary resources, contains possible processing parameters, and performed mechanical tests of products, identifies strength and ductility of bars and wire of various diameters produced from crushed waste depending on the degree of deformation and the place of intermediate annealing in the course of drawing according to the selected mode. Practical Relevance: It lies in determining the processing parameters that make it possible to produce bar and wire products with a specified level of properties.
