26-10-2012 | L. V. Kopeliovich, V. I. Sukhorukov, V. I. Shvetsov, Coke and Chemistry, 2012
Since coking coal is characterized by both elasticity and ductility in the plastic state, the coal charge of coke furnaces that contains a plastic layer exerts pressure (coking pressure) on the chamber walls. The pressure exerted depends on the height and mean density of the charge and on the ...
26-10-2012 | D. V. Onishchenko, V. P. Reva, Coke and Chemistry, 2012
The production of carbon nanofibers by the pyrolysis of sphagnum moss as a result of mechanochemical activation in a planetary mill is considered. The nanofibers are used to create a composite system consisting of carbon and tungsten nanoparticles, which may provide the basis for anodes in ...
26-10-2012 | B. P. Kiselev, S. G. Stakheev, Coke and Chemistry, 2012
The concept of technological value is discussed. On that basis, a method of assessing the technological value of coal is recommended. The technological value of the basic clinkering coal in coking batch (Zh, GZh coal) is assessed. Similar estimates are presented for poorly coking GZhO and Zh ...
26-10-2012 | V. I. Zasel’skii, G. L. Zaitsev, T. A. Zasel’skaya, Coke and Chemistry, 2012
The influence of the granulometric composition of coal batch on the energy requirements of a hammer mill is considered. Means are proposed for reducing the energy consumption in crushing coal batch that already has a high content of the final size class.
26-10-2012 | V. K. Popov, V. I. Butakova, Yu. M. Posokhov, I. L. Rachev, Coke and Chemistry, 2012
Errors in determining coal quality are compared. For the example of the ash content, it is shown that the error in forming the samples is almost an order of magnitude greater than the error in sample analysis. The metrological characteristics and conditions of correct utilization of results ...
26-10-2012 | S. A. Semenova, O. M. Gavrilyuk, A. N. Zaostrovskii, N. I. Fedorova, Z. R. Ismagilov, Coke and Chemistry, 2012
Oxidative modification of coal tar by activated components of low-temperature plasma is considered. Such modification of tar is accompanied by polarization and polycondensation processes, with consequent increase in thermostability of the product.
26-10-2012 | M. S. Chemerinskii, A. G. Starovoit, E. I. Malyi, Coke and Chemistry, 2012
Various methods of preparing coal for coking are analyzed. Laboratory experiments are conducted with a view to obtaining higher-quality coke from batch with a high content of poorly clinkering coal.
26-10-2012 | V. I. Lakomskii, Coke and Chemistry, 2012
Electrode thermoanthracite is a very inexpensive component in production batch for carbon and graphitized electrodes, which are widely used in ferrous and nonferrous metallurgy. The electrical resistance of monolithic thermoanthracite is measured, along with its temperature coefficient of ...
26-10-2012 | M. L. Ulanovskii, Coke and Chemistry, 2012
A brief literature review shows that kinetic research on coal oxidation offers insights into the complex structure of the coal’s organic mass, its properties, and the radical-chain reactions in solids. Correct analysis of the kinetic data depends on experimental information regarding the ...
16-10-2012 | V. V. Klubovich, V. V. Rubanik, D. A. Bagrets, Journal of Friction and Wear, 2012
The effect of low-temperature annealing on the adhesion strength and coefficient of friction of TiN coatings deposited on austenitic stainless steel by the vacuum-arc method is studied. The behavior of the coefficient of friction of titanium nitride upon annealing in air is discussed. It is ...
