The analysis of results of practical application of cast replaceable details of hinged tillage agricultural machinery at operation in a number of the agricultural enterprises of the Poltava region at processing of more than 60 thousand hectares within several years is presented. Comparative data of the resource of parts made of high-strength bainitic cast iron and steel serial analogues of domestic and foreign production are given. The advantages of the method of manufacturing by casting methods in comparison with the traditional method of manufacturing by stamping. This technology allows you to easily make adjustments to the design of the cultivator legs, thus providing a new quality of tillage and pruning of the root system of weeds, which eliminates the need for herbicides. The basis of this technology is the use of composite complex modifiers made by rolling powder mixtures of plastic and brittle components with the necessary observance of the proportions of their ratio. The use of powder rolled modifiers provides the necessary properties and structure of the cast metal required for further heat treatment. It is substantiated to obtain high wear resistance of cast products due to the appearance of TRIP-effect and constant updating of wear-resistant surface layer during operation.

Production Output

The paper deals with the study of the relationship between agricultural development of and agricultural engineering. Production output of certain types of machines and equipment for agriculture are examined. The dynamics of production performance in plant growing and stockbreeding is analyzed. The dynamics of such agricultural development indices as net income, subsidies, taxes, net value added, fixed capital application, etc. are considered. The tripling of output and a steady growth of net profit of agricultural producers are established. It is proven that farm equipment upgrading is less active than net income growth, and thus it was determined that enterprises have the necessary financial resources to generate demand for agricultural machinery. The peculiarities of agricultural machinery production in Ukraine at the present stage are revealed, in particular the causes and consequences of such a situation in production machinery for agricultural enterprises. Two opposite trends in agricultural machinery production are identified, namely, the decline in the production of complex, expensive machinery and the increase in the production of less costly appliances. The condition of the durable equipment in agriculture is analyzed by identifying their value and the degree of wear. Consequences of the increase in the quantity and quality of used machinery in agriculture are revealed. The requirements of agricultural enterprises for the quality of agricultural machinery are identified, and their classification by the requirements for quality, value and service is worked out. The quality requirements include technical and functional characteristics; value requirements consist of equipment prices, discounts, and value-added services. Service requirements comprise quality assurance of information, organizational and maintenance services. In accordance with the established requirements, technical, organizational, economic and social ways to meet these requirements were developed.

Water Simulation

A technology of continuous casting of steel has a large effect on its contamination. In particular, proper organization of metal flows in tundish and mold is very important. After completion a series of casting through a tundish and drop of metal level in it, it possible, that the slag flows from the surface layers of the tundish to capture the metal. An analysis of results of ultrasonic control of finished strip showed, that the basic number of the revealed defects was obtained during strip rolling out of the last slabs of the last heat in a series for a tundish. Metallographic studies determined, that the defects were located in the slab axis zone and filled by macro-inclusions of complex composition. To determine the actual distribution of metal flows, a water simulation of them was accomplished for the existing design of the EVRAZ NTMK tundish. It was determined, that at the drop of metal level in a tundish, a capture of slag from the metal reservoir and its transfer into the main bath of the tundish takes place due to whirligig flows. Following the weight metal consumption, the zone of slag inclusions distribution enlarges. Besides, denudation of the metal mirror in the metal reservoir takes place, resulted in metal secondary oxidation. Based on the results of the simulation, it was proposed to modify the design of the “turbostop”, which is installed in the metal reservoir of the tundish. Besides, it was proposed to remove the dividers installation in the tundish. It was noted, that the proposed steps enable to ensure a minimal level of rejections.

Abstract Technical support of producers of agrarian products has always been and will remain a topical issue in realities of agrarian sector of Ukraine. In recent years, integrated forms of agricultural enterprises have become more widespread, which make it possible to increase and renew a machine-tractor park of their participants. In course of study four main technologies of soil cultivation and their impact were considered, an amount of necessary machinery and equipment, energy and labor costs, and impact on quality indicators of soil health. Also, main organizational forms of enterprises that provide equipment rental services or perform fieldwork were analyzed. Proposals were made regarding a merger of existing enterprises into agro technical centers, which would increase an efficiency of their functioning and cover functions of regional self-government. Also, the most common forms of machinery usage by agricultural enterprises were considered.
