The results of the possibility for using of spent ANF-6-1 fl ux for electroslag remelting and breakage of spent silicon carbide abrasive wheels in the smelting of 20GFL steel are presented. Noticeable advantage of the experimental smelting technology is shown. Saving of expensive materials, reduction of harmful impurities in the metal and increase in the desulfurization rate from 0.0004 to 0.0007 %/min are noted. The use of spent ANF6-1 fl ux for electroslag remelting made it possible to reduce the duration of melting, the consumption of slagforming materials and reducing agents. There is also decrease in electricity consumption by 11 kW/h per ton of liquid steel. Increase in the plastic characteristics and impact toughness of 20GFL steel is shown when using the experimental melting technology in comparison with the current one. At the same time, the strength characteristics of steel remained at the same level. The economic effect at using of secondary materials in the smelting of 20GFL cold-resistant steel is 430...450 rubles per ton of liquid steel.

The Right

In this work, we consider the concept of using a distributed solar power plant, setup on the right-of-way of the railroad. The proposed solution allows to shave peaks of electricity consumption without additional land alienation, using the existing power grids. The concept includes the setup of solar panels on the alienated land of the railroad. PV can be placed directly on the cross ties using damping elements, on the embankment slopes and on the right-of-way land. This solution allows minimizing the cost of solar panels installation along the railway tracks. The North Caucasus railway was considered to assess the gross, technical and economic potential of the proposed solution. The operational length of the railroad there is 6,472 km. The railway consists of large non-electrified sections, segments powered with 25 kV AC and 3 kV DC. The railroad is used not only for cargo transport, but also for long-distance and suburban passenger traffic. We have considered different scenarios for right-of-way land use rate and have shown that possible project costs could be reduced by ca. 25% by double land use only. This does not include shared electric grid infrastructure use that also should benefit considerably, but is hard to be estimated. While the potential nameplate capacity of such power plants within one region is 10s-100s of MW.

The growth of indebtedness of industrial enterprises operating in conditions of economic instability for consumed electricity and the sanctions imposed by the energy supplying organizations for late payments, determine the urgency of the problem of managing the risks of non-payment for energy from industrial enterprises. The article is devoted to the description of the method developed by the authors for managing the risks of non-payment of industrial enterprises for consumed electricity, based on the principles of price-dependent electricity consumption. Based on the study of the mechanism of formation of the cost of electricity purchased by industrial enterprises in the wholesale and retail electricity markets, special methods were proposed to control each component of the cost of electricity: electrical energy, electrical power, electricity transmission services. It justifies the need to develop options for operating modes of industrial equipment, such as nominal load mode, load limiting mode, technological minimum load, in order to effectively implement and use price-dependent power consumption in crisis conditions.Modeling scenarios of price-dependent demand management for power consumption is made on the example of a machine-building enterprise and the calculation and component-wise analysis of the economic effect of price-dependent management and the factors influencing its formation are carried out. The developed method allows you to effectively manage the risks of non-payment of industrial enterprises for electricity, as well as minimize the risks of restricting the supply of electricity to industrial facilities and disruptions in the operation of industrial equipment.

Panel Vector Autoregression

This paper has investigated the inner relationship between economic growth and energy consumption. Firstly, the authors have analyzed industrial level in 31 provinces of China between 1978 and 2011, and then classified them into different groups according to industrialization stages during different periods. Next, empirical study has tested the causality between economic growth and electricity consumption by the means of Panel Vector Autoregression (PVAR). Then we conclude that the causality between electricity consumption and economic growth is bidirectional in Pre-industrial and late industrialization stage, during which reducing emissions is likely to have negative impact on GDP. And thus we need to pay more attention to improving energy efficiency and developing new energy. At the beginning and middle stage of industrialization, there exists unidirectional relation between economic growth and electricity consumption, which implies that a policy to reduce energy consumption makes little difference to GDP.

The results of many years of research on the effectiveness of the integrated use of crop protection means and fertilizers with the application of various tillage systems for cultivation of winter wheat of Moskovskaya variety 39 are presented. The studies were conducted in the European nonchernozem soil of Moscow Region on sod-podzolic medium loamy medium-cultivated soil. It was shown that weeds are mainly represented by broadleaved species with an amount of 270 to 370 pcs/ m2. Among pests, cereal aphids and capsid bugs dominate. Among diseases, Helminthosporium and Fusarium root rot (up to 30–40%) and aerogenic infections – brown leaf rust (15-28%) and leaf spot (17-25%) were noted. Studies showed high individual effectiveness in eliminating harmful causes by using appropriate means of protection – seed disinfectants, herbicides, fungicides and insecticides. Weed infestation decreased by 78-85%, root rot development – by 78-81, leaf diseases – by 91-98, pests – by 78-100%. At the same time, the weak effectiveness of the Alto-super fungicide against Septoria and Karate insecticide against wheat thrips was noted. The effect of protective measures on the stored crop was as follows: seed disinfectants – 18%, insecticides – 21, herbicides – 39, fungicides – 22%. The highest economic effect was obtained with the integrated use of plant protection products – up to 1.07 t / ha of grain. At the same time, the quality of grain, content of protein and gluten, and grain class increased. The economic effi ciency of the integrated protection system ranged from 4.7 to 8.1 roubles for each rouble spent. The best result in terms of economic effi ciency was obtained with moldboard tillage and the use of a full dose of NPK90 mineral fertilizers and a full integrated protection scheme.
