The purpose of this article is study and identification of the most promising trends and engineering solutions in order to improve resource saving and energy efficiency in the production of corundum on the basis of the conducted patent review on melting improvement and optimization. The ways to optimize the corundum production are considered in three directions from the point of view of energy saving. The first direction relates to the development of promising engineering developments. The latter are studied to select rational operating modes and determine the main factors affecting voltage surges during the technological process and useful product yield. Consideration is given to the conditions for reducing specific energy consumption and improvement of production environmental friendliness at all stages beginning from isothermal sintering of corundum, production of electrocorundum, fine corundum to single corundum crystals. The second direction is the optimization of corundum production at all stages for the development of an optimal control algorithm for the technological process. In this case the electricity consumption might be reduced by 10-12% as compared to current standards. The third direction is the development of engineering solutions involving the change of individual structural units of furnaces, namely, the use of modern components and new heat insulating materials, as well as the application of spent heat carriers as the sources of secondary energy resources and the introduction of additional controllers of the automated control system of the process. The analytical study has shown that the result of optimization should be upgraded designs of plants and electrical equipment, which can provide maximum electrochemical efficiency, and corresponding furnace tightness. Criteria for energy supply and energy quality making possible to stabilize furnace material balance and solve resource saving issues have been developed. These measures allow to reduce the loss of raw materials up to 20-25%, the specific energy consumption under the production of corundum by 2-3 thousand kWh per 1 t.

The search for resource-saving and environmentally friendly technologies and technical solutions in the production of food products should occur through the development and development of new analytical methods and constructive measures, which will lead to progress in this field not only in our country but also abroad. The efficient use of processing facilities has always been characterized by its high level of mechanization. Drying is one of the most widespread technological operations in various industries of processing and food production, in particular in the preservation of raw materials. Prospects for the development of drying technologies include reducing energy costs for moisture extraction; improving the quality of dried products; development of highly efficient universal equipment; ensuring the environmental safety of drying plants. When studying different physical phenomena in the process of vibration drying, two methods of research are used, which allow to obtain quantitative regularities. In the first method is used experimental study of specific properties of a single phenomenon, in the second - based on a theoretical study of this problem. The advantage of the experimental research method is the reliability of the obtained results. The analysis of literature sources is carried out and the necessity and possibility of creation of new designs of dryers using infrared influence on the product and vibrational vibrations of the working container for intensification of the drying process is substantiated. The proposed design of an experimental laboratory drying unit for drying granular and granular materials in a vibrating boiling layer allows to identify patterns of changes in the parameters of the drying process, to obtain data to optimize the process and to develop a method of engineering calculation of devices for infrared drying.

In conditions of a high level of industrialization of the economy, the production process is accompanied by the consumption of a significant amount of resources. Due to the fact that material costs account for more than half of production costs, a decrease in the latter is the most important qualitative indicator of economic development. Saving raw materials, materials, fuel, energy helps to reduce the cost of production and the need for capital investments, the introduction of scientific and technological advances, the establishment of new balance relations and economic balance, an increase in production, and an improvement in the financial situation of enterprises.

At production of stainless steel expensive alloying elements, containing nickel, are used. To decrease the steel cost, substitution of nickel during steel alloying process by its oxides is an actual task. Results of analysis of thermodynamic and experimental studies of nickel reducing from its oxide presented, as well as methods of nickel oxide obtaining at manganese bearing complex raw materials enrichment and practice of its application during steel alloying. Technology of comprehensive processing of complex manganese-containing raw materials considered, including leaching and selective extraction out of the solution valuable components: manganese, nickel, iron, cobalt and copper. Based on theoretical and experiment studies, a possibility of substitution of metal nickel by concentrates, obtained as a result of hydrometallurgical enrichment, was confirmed. Optimal technological parameters, ensuring high degree of nickel recovery out of the initial raw materials were determined. It was established, that for direct steel alloying it is reasonable to add into the charge pellets, consisting of nickel concentrate and coke fines, that enables to reach the through nickel recovery at a level of 90%. The proposed method of alloying steel by nickel gives a possibility to decrease considerably steel cost at the expense of application of nickel concentrate, obtained out of tails of hydrometallurgical enrichment of manganese-bearing raw materials, which is much cheaper comparing with the metal nickel.
