ABSTRACT
The primary functional component of continuous casting machines (CCM) for metals and alloys is the crystallizer, which ensures the formation of the billet’s geometric shape and solid shell. The working walls of crystallizers for steel and copper casting are typically made of cathode copper M1 or high-purity alloyed copper alloys. The service life of a crystallizer largely depends on the correct choice of material for the crystallizer walls and the optimization of its design elements. This paper describes the technology for producing copper plates from secondary raw materials in a fire-refining furnace. The results of studying the physico-mechanical properties of plates made from fire-refined copper are presented. The possibility of using these plates as a multifunctional material for the working walls of crystallizers is substantiated. The conducted studies have shown that fire-refined copper is a promising functional material and can be considered a starting material for the production of plates for the working walls of rectangular crystallizers used in continuous casting of metals.
