Tsvetnye Metally

The articles with different directions, elucidated industrial experience and scientific developments of enterprises, companies, research institutes are presented in the issue.

In the paper “Kinetics and selectivity of crushing copper-nickel ores in tumbling mills” it has been shown, that ore is crushed quicker and with lesser overgrinding in rod mill, than in ball mill. Disintegration in rod mill is more selectively.

The theories, explained course of physical processes in zone of electric spark, are considered and analyzed in the paper by R. K. Bairamov. It was shown that experimental and calculated data, obtained during electric-spark dispersion of metals in liquids have been testified in favour of the thermal theory. Basic provisions of the process of metals electric erosion have been formulated on the base of the analysis of the available data.

The paper by A. V. Tarasov is presented to the readers in the section “Magnesium, titanium, rare metals, semiconductors”. The data about raw materials base, technological and quality level of output products by enterprises of tungsten-molybdenum industry at the Russian Federation and countries of Commonwealth of Independent States are adduced in the paper.

The paper about realized researches, devoted to problems of ensuring reliable work and technical excellence of cast part ofpiston of petrol internal combustion engine, is published in “Metal processing” section. The simulation of casting processes using the LVM Flow for cast part of VAZ-21083 piston has been realized. Dislocation of identified casting defects in the piston body in the form of model spheres is shown. Research of the tense state is conducted in the places of dislocation of casting defects. The technique of calculating the fatigue strength of cast part of piston taking into account stationed shrinkage defects has been considered.

Staff and editorial board of “Tsvetnye Metally” congratulate on hero of an anniversary, such as Besser A. D., Glazunov L. A., Dvinin Yu. I., Kuzkin A. S., Tarasov A. V.

The paper about V. K. Zvorykin, who was talented scientist with world-wide reputation, has been published in the “Chronicle” section. The name of television founder was known to experts in gathering till centre of 1980-s in USSR.
