A. V. TERESHCHENKO, N. A. KHODOSOVSKAYA      OJSC “BSW – Management Company of the Holding “BMC” produces a wide range of carbon, high?quality, alloyed and high?carbon steel grades, among which a significant share is peritectic grade steels. Basically, the steel of this group is used to produce rolled products intended for the manufacture of components for the automotive industry. The process of production and casting of these steels is characterized by the greatest instability and is often accompanied by rejects and forced sorting of products. This situation is typical for other metallurgical enterprises. Therefore, the search for technological solutions that ensure an increase in the yield while maintaining the existing productivity of metallurgical units is an urgent aspect of improving the technology of continuous casting of peritectic grade steels. At the same time, the main scientific and technical task is to obtain a stable quality of continuously cast billets, aimed at preventing and eliminating the formation of a number of characteristic defects, primarily cracks on the surface of continuously cast billets and rolled products. The search for methods and technological solutions to improve the quality of products made of peritectic grade steel is the goal of the ongoing research.

E. V. GAPEENKO     Precision control of hydraulic equipment is a distinctive feature of modern hydraulic systems. With the help of special diagnostic devices, it is possible to reliably and simply monitor the operation of hydraulic equipment. Diagnostic methods can be very different. The article lists the stages and methods of checking hydraulic equipment malfunctions, as well as describes the principles of operation of diagnostic devices of well?known world manufacturers HYDAC, MOOG, used in OJSC “BSW – Management Company of the Holding “BMC”. Schematically, the connection of the MOOG tester to the production equipment is presented when checking the servo valve in autonomous and combined mode, without resorting to dismantling the valve. Continuous montoring of the oil purity with the help of the HYDAC FCU device allowed saving time on assessing its condition and taking fast?acting corrective measures to clean the oil from contamination.

N. V. GIRILOVICH, G. V. DOVGOPOLAY      Quality is the degree to which the totality of an object’s inherent characteristics meets the requirements. The product quality control system is a set of interrelated objects and subjects of control, the types, methods and means used to assess the quality of products. An effective control system allows you to make a timely impact on the level of product quality, prevent possible inconsistencies, and ensure their prompt detection at the lowest cost. One of the progressive methods in modern management is the statistical method. The article considers the program element for quality control in OJSC “BSW – Management Company of the Holding “BMC”. This program element is aimed at working with all types of nonconforming products of the enterprise, at finding the root cause and statistical analysis for these reasons
