The paper deals with electric power quality research, in the load buses of the electrical networks of oil processing plant (“Production Association “Kirishinefteorgsintez”, LLC). Measurements were carried out under conditions of operating equipment at the distribution substations of the enterprise and at the division boundary of inventory responsibility with the power-supply system at the points of power transmission from the power-supply system to the industrial consumer. Assessment of the allowed contribution to the deterioration of electric power quality showed that at the increase in the rated capacity of drives based on frequency converters over 12% of the total installed capacity of electricity receivers of oil processing plant, the maximum allowed voltage waveform distortion coefficient values at the points of power transmission will be exceeded. To implement normalizing the electromagnetic environment and lowering non-sinusoidality of voltage, proposed is a system of measures, that allows controlling electric power quality indicators within the limits, stipulated by regulatory documents, resulting to reducing the risk of penalties by the power-supply authority and large scale undersupply of products under conditions of continuous technological cycle.
The prospects of production of special properties steels in the Russian and global metal market are estimated. The necessity of using new types of steels is substantiated. The prospects of introducing steels with special properties developed by PJSC “Magnitogorsk Iron and Steel Company” to the market are determined. Evaluation of measures for the production of large volumes of products showed that there is a problem of a significant increase in the time of manufacturing and delivery of output products to the consumer. As measures to ensure the modernization of the technological complex of the steel enterprise and reduce the time for steel production, the system of jet heat treatment of metal is proposed. According to the results of comparative analysis of the MAGSTRONG H500 and HARDOX 500 alloys used in mining equipment under conditions of increased wear, it was revealed that the proposed method of heat treatment allows one to achieve high wear resistance properties, with high coefficients of tensile strength and toughness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
