The socio-economic structure and the structure of economic production in Ukraine are get increasingly subjected to the consumption of goods and services. Problem Statement. In the outlined conditions, the problem is that in most cases, the economy has been already controlling the human being, not vice versa. Purpose. The development of a systematic approach to the problem of revealing the essence of the relationship between the “subject” of economic space management, the human being, and the “object” of management, the economic space, in order to find ways to return to human-centered socio-economic structure of the country. Materials and Methods. For the first time, a new concept of “social effect” has been introduced. It is an analog of the well-known lexicographic effect proposed at the beginning of the 21st century by Full Member of the NAS of Ukraine V. Shirokov, which may be regarded as a phenomenological framework of the theory of complexity and the corresponding specific theory of economic information, on the one hand. On the other hand, the complexity theory, the Kolmogorov information, and the Levenheim-Skolem theorem may be considered formal correlates of the lexicographic effects in economic systems. Results. This approach is considered system-creating to describe the holistic processes of relations of economic systems of five levels with the phenomenal property of self-compensation of complexity. The separation of structural, substantive, and subjective properties, as well as the relationships between them gives the analyzed economic reality the property of being a system. Conclusions. Based on the above assumptions and general theoretical and informational ideas about socio-economic systems of five levels as formal correlates of the lexicographic effect, it has been proposed to coordinatize and to unify information in the economic space of these management systems as a basis for establishing the “source — form — content” equilibrium in accordance with the rule of \"common goals\".","PeriodicalId":19061,"journal":{"name":"Nauka ta Innovacii","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44627402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main factor of oxygen blowing in converters is the interaction of oxygen jet with the molten metal bath. It determines hydrodynamics, heat and mass transfer, slag formation and causes metal losses with emissions affecting the yield of liquid steel. Problem Statement. The most promising research aimed at improving the slag formation and increasing the yield of liquid steel in the conditions of modern metallurgical practice. It deals with the electro physical effects on the metal smelting process. It includes the method of low­voltage potentials application developed in the Iron and Steel Institute of Z.I. Nekrasov of the NAS of Ukraine (ISI NASU). Purpose. To study the possibilities and to evaluate ways to improve the efficiency of the method of low­voltage potential application for top oxygen blowing in the converter. Materials and Methods. The tests were carried out on a 160­ton industrial oxygen converter equipped with a device for low­voltage potential application on the lance and a metal bath with imposition of a negative or positive polarity to the lance throughout the blowing period. The top blowing option through five nozzle tip has been studied while producing medium carbon steel with intermediate deslagging. Results. The analysis of the array of experimental industrial heats carried out in 160­t converters in conditions of low­voltage potential application, has made it possible to identify the following patterns of changes in the electrical characteristics of the bath from the blowing parameters. It was established that regardless of the polarity of the potential at the lance, the magnitude of the values of current and useful power of impact in lance–metal bath circuit over blowing periods depends on: the level of the voltage at the source of current and the height of the lance in the converter's volume above the metal bath. Thus, it is necessary to maintain the position of the lance: from the beginning of the blowing, depending on the location of the scrap, at a height of 0.9—1.0 m, in the main blowing period, at 1.0—1.2 m, and in the final period, at 1.0—1.1 m, which is made taking into account the effective support of the current during the blowing at an adequate level to achieve the maximum level of the effect of the low voltage potential application. Conclusions. Industrial testing of the recommended blow mode in 160­t converters showed the possibility to almost double the efficiency of using low­voltage potential application compared with the previously developed and accepted at the plant mode of its application.","PeriodicalId":19061,"journal":{"name":"Nauka ta Innovacii","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47965291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
