The thermodynamics of iron reduction from electrofurnace slag by high-alumina mixture in an arc furnace is studied. The thermal balance of the reduction process is calculated. The introduction of high-alumina mixture in the arc furnace during smelting converts some of the iron from the slag to metallic form. The heat generated reduces the power consumption, shortens the smelting cycle, and increases furnace productivity. © 2014, Allerton Press, Inc.

The influence of the temperature and deformation in the finishing stage of rolling on the structure and properties of low-carbon microalloy steel is investigated. The microstructure and mechanical characteristics of the steel are studied as a function of the final temperature Tf.r in the finishing stage and the time interval between the last rolling cell and the accelerated-cooling system. © 2011 Allerton Press, Inc.

In laboratory conditions, the influence of the temperature interval in the finishing stage of controlled rolling on the structure of hot-deformed austenite, the final microstructure, and the properties of low-carbon microalloyed steel is studied. Experiments show that reducing that temperature interval within the range Tnr-Ar3 reduces the grain size in the direction transverse to rolling and increases the number of deformational twins within the hot-deformed austenite grains. The effect is to improve the grain size and uniformity of the ferrite-bainite microstructure and hence to improve the mechanical properties of the thick sheet produced. © 2012 Allerton Press, Inc.

The resistance of low-carbon microalloy steel to deformation in hot pressure treatment is investigated. Three types of curves have been identified on the hot-compression diagram and may be used to judge the softening of the steel on deformation at 1050-700°C. The qualitative relation between the compressive strain rate and the temperature range corresponding to each type of curve is described. With increase in compressive strain rate, the resistance to deformation increases in both the γ and γ + α regions. The resistance to deformation is studied as a function of the temperature, with variation in the strain and strain rate. In addition, the strain-rate sensitivity and temperature sensitivity of the resistance to deformation (the mean yield point) are studied as a function of the temperature, the strain, and the strain rate. On the basis of the variation in the resistance to deformation with decrease in temperature, various methods of determining the temperature range of γ → α transformation in the given steels are considered. © 2011 Allerton Press, Inc.

Attention focuses on how the basic hot-deformation parameters in thermomechanical treatment affect the structure formation of hot-deformed austenite, the microstructure, and the mechanical properties of low-carbon microalloy steels used for the manufacture of large-diameter gas pipelines. In rough rolling, small uniformly recrystallized austenite structure is formed and largely retained on subsequent cooling, while the cold working of austenite increases in the final rolling and the annihilation of structural defects is prevented after deformation and before accelerated cooling. © 2013 Allerton Press, Inc.

Contact geometric measurements of pipe blanks in the edge-bending section of the TESA 1420 pipe-electrowelding line are made by a new method. The influence of the pipe blank's edge geometry on the shape of the edge zone after the subsequent processes is assessed. The stages of the experiment are outlined. The experimental data are obtained in the form of the coordinates of points on the edge. Measurements of the edge geometry by different methods are compared. The use of photographic-survey measurements is promising for use in the production of large-diameter pipe. © 2014 Allerton Press, Inc.
