Despite the active development of modern production methods, producing parts by casting remains one of the most common and economically profitable. At the same time, modern production places high demands on the quality of cast parts. It is possible to ensure high-quality castings by forming a homogeneous dense ingot structure (casting). In turn, these indicators can be achieved by regulating the rate of solidification of the casting and the distribution of alloying elements inside it throughout the volume. One of the promising ways to control the casting structure is casting according to gasified models using inoculators (suspension casting). Using ferroalloy particles in styrofoam models simultaneously with inoculators (refrigerators) can adjust the number of crystallization centres and the distribution of alloying elements. One of the important indicators in the production of castings by suspension casting is the absence of defects, chemical heterogeneity, porosity and mechanical properties. These indicators can be obtained using inoculators used in suspension casting. In suspension casting, from the point of view of creating waste-free technologies, using various metal wastes during casting is promising chips, slag components, trimmings, die-cuts, etc. This project will introduce inoculators and use foundry waste, providing the required service and technological properties.
