IMPROVING THE DURABILITY OF THE MECHANICAL EQUIPMENT OF THE SHAFT BALANCING SYSTEM OF THE 1680 MILL STAND

Abstract

Current article is a research devoted to an important aspect of improving the durability of mechanical equipment of the shaft balancing system of the working stand of mill 1680, used in the cold rolling process. The paper deals with the methods of reinforcement of machine parts and mechanisms necessary to ensure high reliability and durability of industrial equipment used in metallurgical production. Particular attention is paid to the application of functionally active coatings obtained using the method of self-propagating high-temperature synthesis (SHS) in order to increase wear resistance and reduce energy consumption in operation balancing mechanism. In addition, the article considers the principles of stand operation of rolling mill 1680, including consideration of the features of rolls, supporting rolls, pressure mechanisms and balancing systems, as well as the technology of roll drive and rolling thickness adjustment mechanisms. The final part of the article presents the results of experimental studies on wear resistance of steels with different protective coatings obtained by SHS method, taking into account their microhardness and dependence of wear intensity on the type of alloying, to improve the durability of mechanical equipment.
