The paper contains a description of an alternative method for the production of ferrosilide which includes self-spreading high-temperature synthesis (SHS) from dispersed waste products of mechanical engineering. Forging scale acts as an oxidizing agent and supplier of the iron. Silumin chips act as a regenerator and supplier of a silicon. Graphite chips are a carbon supplier for the alloy. Such method of the SHS-ferrosilide production differs from the traditional analogue by not only high values of corrosion resistance, but even mechanical properties due to the features of alloy synthesis (additional alloying with copper, nickel and aluminum, high-speed liquid-phase formation and cooling). The consumer quality of SHS-ferrosilide is characterized by a set of particular indicators: corrosion resistance, strength, hardness, which are significantly determined by the quantitative and qualitative composition of the burden of the SHS process. A technique for optimizing the composition of the SHS process charge is developed on the basis of minimizing the objective function as an absolute difference in the integral quality coefficients relative to the customer’s assigned value. This takes into account the priority of individual particular quality indicators of SHS-ferrosilide, which depend on the composition of the burden of the SHS process and adequately described by the functional dependencies on its parameters. This method allows to optimally select the composition of the burden of the SHS process, which guarantees the production of SHS-ferrosilide with integrated quality in accordance with the requirements of the customer. The technological process of obtaining SHSferrosilide differs favorably from the traditional one not only by the quality of the material obtained, but also by the absence of expenditure of energy from external sources, stability and wastelessness.
