A.B.Moller, O.N.Tulupov, D.I.Kinzin, S.A.Levandovskiy, S.Yu. Sarancha. DEVELOPMENT OF TECHNOLOGY OF ACCELERATED COOLING OF SHAPE-ROLLED STEEL FOR PROVIDE SPECIFIED MECHANICAL PROPERTIES. Abstract. The work is intended to solve the problem of increasing the effectiveness of section rolling mills, by controlling the mechanical properties of metal and the content of expensive alloy additives (vanadium) through the preparation of organizational and technological events to reduce by at least fifty percent of the content of vanadium in the billets intended for the production of shaped and long products according to GOST 19281-2014. Keywords: accelerated cooling by water, excluding microalloying of steel, section rolling, mechanical properties, GOST 19281-2014.
S. Spuzic. HOW TO REDUCE IMPACT OF INDUSTRIAL ROLLING ON GLOBAL RESOURCE CONSUMPTION AND CLIMATE CHANGE? Abstract. Motivation for scrutinizing rolling process is triggered by growing evidence of anthropological causes of global climate change that are amplified by worldwide acceleration in natural resource consumption. While the key industries such as steel manufacturing systems are condition sine qua non for our progress, the rationalisation of relevant technologies is of critical importance. Hot rolling systems, which are in the heart of steel industry, are ineludible examples of unavoidable man-made enterprises crying for rationalisations. The promising avenue for decisive progress in (re)designing rolling systems is by implementing Big Data strategy for mitigating the problems in untenable production and in designing new processes. This strategy stems from recognising importance of knowledge extracted from data accumulated in industrial repositories. An internationally maintained collaboration between industry and academe is the prerequisite for application of proposed strategy in practice. Keywords: global warming, natural resources, industrial rolling, rationalisation, big data.

M.I.Rumyantsev. DEVELOPMENT THE METHODOLOGY FOR SYNTHESIS OF SOLITARY REDUCTIONS BY MEANS THE HORIZONTAL ROLLS IN WIDE STRIP HOT ROLLING MILLS. Abstract. The patterns of the distributions of the solitary reductions by means of the horizontal rolls in roughing and finishing groups of wide strip hot rolling mill have been considered. The methods for a choice the solitary reductions, providing the minimum deviation between real modes of deformation and theirs first approximations, have been identified. Keywords: wide strip hot rolling mill, solitary reduction per pass, mode of the reductions in roughing group, mode of the reductions in finishing group.

Abstract. The relationships between drive usage of a rolling stand and yield strength and summary reduction were obtained. This relationships makes it possible to formalize a choice of draughting schedule in combination pickling-rolling mill 2000 (PLTCM 2000). The formula was found using target power method. The degree of conformity between forecasting and actual rational thickness achieved 99,8%. Keywords: cold rolling, combination pickling-rolling mill, draughting schedule, engine power, drive load factor.

The article describes the equipment and technology of producing hot-rolled steel for subsequent cold forming of various types of fasteners. Keywords: hot-rolled steel, wire, calibrated roll, drawing, fastener, cold forming, the degree of deformation, compression.
A.S.Limarev, M.Y.Ushakov, I.Y.Mezin. REVIEW OF THE MAIN REQUIREMENTS FOR PERFORMANCE AND QUALITY CHARACTERISTICS OF THE RAILWAY BOLTING. Abstract. The article discusses the requirements for rail rail bonding. The intermediate bonders are designed for secure connections to the rail base of the rails and provide the electrical insulation of rails in areas with self-locking and electric traction. Presented variety of designs of rail bonders used on the territory of Russia. The prospects for development of rail bonds production at JSC "MMK-METIZ". Keywords: rail fasteners, railroad, terminal, anchorage bond, the terminal bolt bond List the keywords.
