Estimation of quality of hot pressed briquettes as a type of metallurgical charge materials

The basic principles of construction are formulated in the work and a description of the technological process of hot briquetting of ferrous metal waste as a way of converting fine metal particles into a dimensional semi-finished product of a given size and chemical composition is given. The description of equipment for the implementation of this process with highly efficient non-oxidizing heating and complete safe neutralization of flue gases is given. The results of melting of hot-pressed briquettes in various melting units are presented. It is shown that briquettes cleaned from coolant with a density of 6500–7100 kg/m3 are full-fledged substitutes for bulk scrap. Recommendations and a feasibility study on the feasibility of introducing the hot briquetting process into production at the enterprises of the bearing, machine-building and metallurgical industries, followed by the use of hotpressed briquettes to produce cast billets for their own purposes, are given.
