Аннотация: In this article various technological schemes for processing waste in the form ofchips of an alloy of an aluminum-silicon system are presented. It was noted that theprocessing of fine waste of the chips type is always accompanied by oxidation of themetal due to the large surface of contact with the air. ToПоказать полностьюeliminate the loss of metal intooxides during re-melting, this study proposes processing chips by pressing to obtainbriquettes (a method of hot extrusion is meant by ‘pressing'). Processing involvesthe receipt of briquettes from rods. The processes of cold and hot briquetting wereundertaken separately. The results of applying the scheme using real production wasteare presented in this study. The tensile strength achieved was up to 270 MPa. Therelative elongation to rupture was 10–25% and the area reduction after rupture was25–45%. There were no large differences in the use of briquettes obtained by coldprocessing and hot processing. The conclusion is drawn about the overall effectivenessof the application of the waste processing without the use of the metal melting.
