Chernye Metally

The issue is opened by the interview with Anatoly N. Savenok, general director of Byelorussian Steel Works. It is accompanied by three articles prepared by the specialists of this enterprise.

A. A. Sotnikov, A. V. Demin and S. V. Terletsky described complex reconstruction of No. 3 continuous caster for billets at Byelorussian Steel Works. As a result of this reconstruction, productivity of continuous caster increased by 26 %, providing required level of quality parameters. Additionally, casting of round billets (with 200 mm diameter) dor tubemaking has been put into practice at this caster.

V. G. Razdobreev, P. V. Tokmakov, V. A. Lutsenko et al. investigated power-saving measures in production of reinforced rolled bars at 320 rolling mill of Byelorussian Steel Works. It is concluded that 1050 ºC initial temperature for rolling of 140x140 mm billet is the optimal technological mode.

V. I. Savich, O. G. Cherneta, A. N. Korobochka et al. presented the paper "Features of forming high-resistant coatings using dual-stage method". Regularities of forming high-resistant coatings in the surface area of tool steels and hard alloy cutting inserts are examined for dual-stage method of their fabrication.

Emission reduction at coke ovens with the PROven pressure regulation system was analyzed by F. Huhn, F. Krebber and J. Kühn-Gaidzik. Since the installations at the former coke plants August Thyssen and since 2003 at the most modern plant Schwelgern the PROven (Pressure Regulated Oven) system has been used worldwide for emission reduction. With the pressure inthe coke ovens adapted to the individual carbonization status the fugitive emissions are lowered considerably. Another material in this thematic section (" Development of a new type of single oven pressure control system for coke oven batteries") is presented by W. Faust, E. Lonardi, T. Hansmann and S. Pivot.

This issue also contains 4 article on rolling: "Productivity rise and quality improvement of new equipment, technologies and finished products in the center of attention" by K. Letz and U. Stellmacher; "Up-to-date longitudinal cutting lines for providing increased quality requirements" by J. Epp; " Increasing the efficiency of conventional pickling lines by using hydroabrasive waterjets" by J. Hemmelmann, D. Hein, W. Krumm and K. Boguslawsky; " Pull-oriented precision strip manufacturing" by J. Deuse, F. Bohnen and M. Indra.

New composite materials for automotive industry developed by ThyssenKrupp Steel Europe are observed in the paper by U. Ratzek. It includes such applications as hybrid cars and electrocars and such materials as sandwich materials, TPN-steels, hot-rolled sheet metal manufactured using open-coil annealing.

Power engineering and ecological problems are presented in this issue by the paper "Coke plants in the focus of air pollution control - from German TA Luft to legal demands of the EU" by M. Hein.
