The main driving forces behind a spreading process of gas emissions from technological companies into the atmosphere have been analyzed. The main factors determining a spread of harmful substances at long distances from emission sources have been highlighted. The general approach to forecasting the spatial distribution of metallurgical enterprises gas emissions at large distances based on the principle of maximum danger has been proposed.

Usinskoe manganese field one of the largest in Russia in terms of (the carrying reserves - 98.5 million tonnes probable reserves – 150.4 million tons). Manganese ore deposits Usinskoye characterized by comparatively low manganese content (18 – 22 %) and a high content of phosphorus (0.2 – 0.3 % and more). Developed technological flowsheet Usinskaya ore, which involves the use of X-nofluorestsentnoy (X-ray radiometric) separation for lumps and jigging for small. Based on the analysis of the processes of smelting manganese ferroalloys and chemical composition of the concentrates produced at enrichment of manganese ores of new Usinskoye field, developed the optimal flowsheet of obtaining the whole range of manganese ferroalloys.

Development research of a complex of methods of quantitative chemical analysis of red mud and its products (cast iron and slag) are achieved. The possibility of simultaneous determination a lot of macro-component count and trace elements in a wide content range (from n∙10 % to n∙10–4 %) is shown, using the atomic emission with inductively-coupled plasma, infrared-absorption and gravimetric methods of analysis.

The calculations of the mass of titanium nitride formed in the austenitic steel in the range of concentrations of titanium 0,1 – 0,7 % and the metal from 1525 to 1456 °C. It is shown that 61 – 63 % of the total weight of titanium nitride is formed in the tundish ladle and a 37 – 39 % – in the mold to form coarse defects such as “cakes”. Lowering the temperature of austenitic steel in the tundish ladle by 10 °C can redistribute the mass of titanium nitride released in steel downsize “cakes” in the mold by 14 – 15 %.

Based on studies of samples EP220 and EP929 alloys in liquid and solid states the parameters of high temperature melt preparing are defined and justified. Structure of liquid alloys when heated to a certain temperature becomes more equilibrium. During the crystallization process of melt is formed cast metal, characterized by small grain structure, high degree of dispersion of the dendrites, higher density and hardness of the matrix. Implementation of the high temperature melt preparing regimes in industry leads to improve ductility, increase hot strength and quality. Proposed technology does not used all opportunities laid down in the structure of the alloy after high temperature melt preparing. An additional effect can be achieved by increasing the melt holding, optimization of vacuum arc remelting, deformation and heat treatment technology, taking into account the structural changes of the hard metal.

This article discusses the direction of energy conservation through the development of new designs of heating and heat treatment furnaces. In particular, we consider the design of chamber heat treating furnace with shared working space. If necessary, reducing the volume of the working space of the furnace, due to the small cages mounted on the hearth removable partition which separates the working space of the furnace into two chambers 6 m long and 12.6 m baffle is installed in a particular recess, located in the hearth and laying a fixed by stretch marks. If you need to handle long items partition is removed, and formed on the hearth void is filled with a filler. The results of the tests of a new furnace design in industrial environments that have shown performance and energy efficiency of the proposed design of the furnace.

These parameters of deformation distribution density and indexes of the stress -deformed state of grains at 35ХН3МФ metal cylindrical upsetting specimen are defined using dividing grids with cell dimensions similar to the average grain size. Standard correlation functions of grain deformation have been developed.

Uralmashzavod is used as basis to assess technical re-equipment of chamber vertical heat-treatment furnace with applying modern technologies of furnace-building and modern materials. The calculation of thermal balances and furnace primary performance characteristics was made before and after re-equipment. Significant improvement of furnace performance characteristics after technical re-equipment was confirmed.

The results of electromagnetic non-destructive online monitoring of austenite phase transformation under conditions of industrial hot strip mill are reported. It is shown that the non-uniformity of cooling of hot rolled low carbon high strength steel coils during conventional manufacturing process induces heterogeneous microstructure and mechanical properties both along and across the strip. The microstructural non-uniformity formed after hot rolling is then inherited downstream, which can be a hidden cause of thickness deviation defect that manifests itself cold rolling. Recommendations are given as to decrease and avoid the non-uniformity of microstructure in hot rolled strips to improve the quality of final product.

The features of the formation of pearlite structure in the decay of a pure austenite and austenite to the presence in it of dispersed non-metallic inclusions, which are able to move together with the growth front pearlite colonies by border diffusion of “pumping” of their atoms. It is shown that this kind of dispersed particles have a definite inhibitory effect on the velocity of the longitudinal growth of ferrite-cementite colonies. This can lead to concentration of particles at the boundaries of pearlite colonies growing in the final stage of the process.

Viscometric study conducted 9H2MF liquid steel and 75H3MF taken from the drive shafts reversing mill, characterized by varying degrees of at- tenuation of ultrasonic waves. From the measurements, the conclusion about the nature of the influence of defects detected by ultrasound method, the nature of the temperature and time dependence of the kinematic viscosity of the liquid steel and 9H2MF 75H3MF. Ultrasonic testing was conducted using ultrasonic flaw detector by Krautkremer. Viscosity was measured by liquid steel damped torsional vibration crucible melt during heating and subsequent cooling of the samples in the temperature range from 1500 to 1580 °C.

The evolution of structure and mechanical properties of quenched low-carbon alloyed steel 15Cr3Mn3MoVTi after complex deformation-ther- mal treatment is investigated. It was shown that successive combination of cold radial forging with deformation ratio 60 % and one-time accelerated heating at 900 °C with water quenching provides nanostructured condition of investigated steel with average lateral dimension martensite lath near 80 nm and high level of mechanical properties. Increase accelerated heating temperature or increase number of heating cycles reduces to coarsening of steel structure.
