The study subject is relevant because the management accounting approach has to be introduced to organization of production, allowing to make innovative decisions for improving the consumer properties of steel slabs in continuous casting machines. The goal of the study is to develop the technical tools for implementing an adaptive control system for management accounting in the zone of the secondary cooling system. The task of the study is to design a construction and manufacturing technology for spray guns (nozzles) based on powder metallurgy, ensuring the necessary dispersion of the liquid. Full-scale and laboratory-scale experimental investigations were used as a method allowing to make informed decisions. A set of nozzles has been sold to an enterprise. The adaptive method of control in manufacturing-technological systems is used as the basic one in management accounting. Further studies will be directed to use these results in technologies of others industries.
