The article substantiates the expediency of applying the basics of resource saving in the development of innovative technologies for strengthening serial parts and restoring worn ones. At the same time, the main task is the rational use of available material resources in the conditions of a decline in production, when it becomes profitable to restore metal-intensive parts worn out to a critical level. In capital repair of machines, the main problems are associated with the energy intensity of the process and a significant number of rejected parts that cannot be restored. Currently, most of the worn-out metal-intensive cast iron and steel body parts that have exhausted the resource are subjected to energy-intensive melting. For the reuse of metal-consuming parts in operation, a technology has been proposed for multilayer banding of a worn surface, in which steel tape is used instead of traditional banding rings. Winding the tape occurs under an interference in several layers. In this case, a multilayer bandage with interturn stresses is formed, which is not inferior in strength to a whole banding ring. The use of a steel “bandage” for the “treatment” of parts reduces the metal consumption for its manufacture by 2.5 times in comparison with the well-known one-piece ring made of round steel. As an example, the article substantiates the possibility of carrying out the banding process in relation to the restoration and strengthening of the seat under the bearing of the housing part. A multilayer bandage can also be used in the recovery of metal-intensive rolling rolls written off in scrap used on broadband cold rolling mills.

Experimental Facilities

In order to meet the demand of steelmakers, series of experimental facilities such as thermo-mechanical simulator, pilot hot rolling mills, controlled cooling system, pilot cold rolling mills, simulator for continuous annealing of strips, and hot-dip galvanizing simulator have been developed and applied by the RAL. These instruments can be used to simulate different processing technologies of steel forming which include continuous casting, hot rolling, controlled cooling, cold rolling, annealing and surface treatment(such as coating), etc. They provide unique research means for the R&D activities of China’s iron and steel industries. The characteristics, experimental functions, performance parameters and application of these facilities are introduced in the paper.

The current stage of reforming the Armed Forces of Ukraine (AF) confirms that the crisis in the country's economy has significantly affected the system of logistics of troops, which ensures its main task – to maintain the combat readiness of military units and ensure their livelihood in peacetime. The war in the east of the country and the existing state of providing troops showed the need to improve the organization and management of the process of logistical (technical, rear and medical) provision of training and combat use of the Armed Forces of Ukraine, which is currently in the phase of perspective changes and necessitates the development of a new concept of military information management and logistical flows, which will be implemented by a new, more efficient structure, called the "military logistics system". The purpose of the article is to determine the directions for the creation and accumulation of an optimal nomenclature of stocks of material resources in peacetime and their rational separation at the tactical, operational and strategic levels of management. The article describes the contents of the concepts of "logistics", "echelon", "stocking", "operational accounting". Important tasks of modern conditions of process of creation and management of stocks in the course of reforming of the Armed Forces of Ukraine are systematized; variants of the offered models of inventory management are outlined. The goal is achieved through theoretical and experimental research on volume optimization and material separation at all levels of management, which is one of the key problems of military logistics.

Definition Of

In a market economy, it becomes important to improve the organization of enterprise management and, above all, the production process, efficient use of financial, material resources and inventories. Effective management of material resources increases profits and provides the necessary investment. To maintain high profitability and liquidity, the management of current activities of enterprises, in particular inventory management plays a significant role. The categorical apparatus of material resources management at the enterprise is considered, the definition of “material resources” is generalized, the definition of "material resources management" is offered, and also the system of material resources management at the enterprise is considered. In the management of material resources at the enterprise there are 2 approaches – logistics and reengineering. The main tasks of the mechanism of management of material resources of the enterprise of building materials are defined. These are: increasing the efficiency of material resources and choosing cheap sources of funding; introduction of new production, resource-saving technologies; minimization of costs for procurement, production and marketing activities; increasing the interest of employees of all services in the effective performance of their duties; product quality management. The analysis of efficiency of use of material resources at the enterprises of building materials which has shown, that manufacture of production is rather material-intensive is carried out. This is evidenced by the share of material costs in the cost of work, and the value of the utilization factor of materials indicates the economical use of material resources in production. Reserves for improving the efficiency of material resources at construction materials enterprises have been identified. The ways of the most rational use of material resources of construction materials enterprises are offered, in particular it is improvement of a design and technology of manufacturing of products, introduction of more progressive norms of expenses of resources, use of substitute materials, and reduction of losses at stages of transportation, storage and industrial use.

Purpose is development of tools for assessing the emergency hazard of facility for disposal of explosive conversion products and materials. Results have been obtained by means of the economic and mathematical modelling methods, with use of the fundamental provisions of probability theory. The main task of conversion products and materials disposal is the creation and organization of safe technological processes aimed at returning the material resources contained in the conversion products to the state’s economy after the appropriate processing, rather than at destroying these resources. As a methodological basis for assessing the emergency hazard of a facility, a provision has been accepted that an integral measure of the disposal process hazard is the economic assessment of accidents. A scheme has been constructed of successiveness of the disposal facility events and states that can lead to an accident, on the basis of which a probabilistic model of its occurrence is developed. Proposed probabilistic model of an accident initiation at the facility for disposal of explosive conversion products and materials makes it possible to predict the behaviour of facility, based on results of the equipment and service personnel state survey, as well as on the analysis of the environmental conditions.

Necessity and reasonability to use gapless connection between contact surfaces of lining straps of work rolls chocks and facing strips of housings (inner lining straps of back-up rolls chocks) to reduce dynamic horizontal forces during rolling and increase durability of equipment are considered. Technical solution is described on base of roughing reversing rolling stand of thick sheet rolling mill 3000 of PJSC ‘ILYICH iron and steel works’ (Mariupol city, Ukraine) which can be used on most heavy loaded sheet and tube rolling mills.
