Technologies \n aimed at a decrease in the fraction of metals obtained by \n conventional remelting in the total volume of cast product are very \n promising. Economical efficiency is achieved owing to the use of \n metal reduced from mechanical engineering wastes by exothermic \n melting. Such wastes are scale, ferrous and non-ferrous metals \n chips [1]. \n Manufacturing process of steel production from mechanical \n engineering wastes consists of several stages. At first, refractory \n graphite mold is filled with thermite mixture composed of wastes. \n This thermite mixture is ignited, and exothermic oxidation-reduction \n reaction is started. This reaction produces melt of metal and dross. \n Molten metal fills casting mold, and dross comes to the surface [2 – \n 5]. \n It has been found experimentally that (1) the completeness of \n chemical element reduction depends on the temperature of the \n exothermic reaction; (2) the intensity of the exothermic reaction is \n influenced by the proportion of the thermite mixture; (3) high \n intensity of aluminothermic melting accompanies short-time \n emission of gaseous phase and splashing of dross and metal melt. \n Moreover, increasing the reaction temperature decreases the \n extraction of reduced metal owing to melting loss of its main \n components and has a negative influence on metalware structure.
