Justification of management decisions on the modernization of Volga-type dry cargo ships based on an express analysis of the market situation

The market situation, as in the global. so on a local scale, it is quite changeable and reacts sensitively to the state of the political situation, socio-economic indicators of the country, changes in legislation, etc. Depending on the changing market situation, the company also needs to reorient the scope of its activities, depending on the requirements of the market, in order to be able to provide services or goods in demand in the new market conditions with the greatest efficiency. The presence of several directions of the company's development leads to some tension in making a management decision. This requires research and analysis of the current market situation. The article discusses the rapid analysis of the market situation in order to make a management decision in relation to an asset: a cargo ship. A methodology for conducting express analysis based on information published in open sources has been obtained

Monitoring the oxygen removal process at the final stage of melting steel

This article deals with removing oxygen at the final stage of steel smelting in arc steel-making furnaces. It is shown that the remaining oxygen during crystallization forms floccules and significantly reduces the quality of the finished metal. During the subsequent metal processing by pressure on these floccules, the metal is torn apart and makes it impossible to obtain a steel sheet. Deoxidation is performed with expensive ferroalloys, and their consumption must be minimized. To achieve economic efficiency, it has been proposed to use recycled aluminum slag as a relatively inexpensive local deoxidizer. To optimize the deoxidizer consumption, a rapid analysis method was developed using the electromotive force (EMF) determination to determine the oxygen activity in liquid steel. As a result of the study, the composition, structure, and technological parameters of deoxidized steel were determined. The use of this technology in production will make it possible to obtain high-quality steel and improve environmental protection through secondary aluminum waste.
