Chernye Metally

The second issue of "Chernye metally" journal, 2015 is opened by conventional section "Metallurgical news abroad". The following section "Development of metallurgy in Russia and CIS countries" is presented by 4 articles.

The paper written by O. A. Timokhin "New equipment for casting of large billets" is devoted to full or partial volumetric crystallization of steel portions that is being created thanks to heat transferring from liquid steel to mould walls in lateral and axial directions to cooling drum. Basic technical solutions, including design of main units for ingots with 850 mm diameter of cross section and industrial casting machine with 60 tons steel pouring ladle are worked out in accordance with the new technology; calculations of rate, output and heat transferring parameters are presented as well.

E. A. Goli-Oglu et al. has examined in his publication metallurgical quality of heavy plate form molybdenum and nickel-molybdenum boiler steel after normalization and consequent rolling at 4200 rolling mill in Fredrikswerk works of NLMK Dansteel (Denmark). It is concluded that the technology with differential Nb alloying depending on thickness level and impact requirements at negative temperature in longitudinal and transversal directions is the most expedient.

Problems and achievements in manufacture of pumping and compression pipes with external upset ends at Pervouralsk New Tube Works are elucidated in the paper written by M. V. Erpalov, A. A. Bogatov, S. V. Systerov and Yu. B. Kulyomin. Usage of SMS Meer press and the new calibration technology, together with choising of efficient lubrication and quality improvement of its application on tool allowed to manufacture the tubes with external diameter 60.3–88.9 mm and wall thickness 5.0-6.5 mm, meeting the requirements of national (GOST 633–80 and GOST R 53366–2009) and American (API 5CT) standards.

The specialists of the Institute of Engineering Science of the Ural Branch of the Russian Academy of Sciences proposed to use high-carbon hypereutectoid steel for the production of hot rolling forged rolls. It has been found that the possesses steel presented ductility sufficient for hot deformation (forging) with small single compressions. According to its properties steel C1,4Cr2NiMoWNb can be recommended for manufacturing solid-forged rolls and bandages for composite rolls of hot rolling process from ingots weighing up to 10 tons.

The section "Coke-making production" includes the papers by U. Poth and R. Kim, as well as by J. Kuhn-Gajdzik et al. (ThyssenKrupp Industrial Solutions AG) - about the new coke oven project at Dragon Steel in Taiwan and about the EnviBAT pressure regulation system at coke plant.

The papers in the section "Iron and steel making" are devoted to the following problems: predicting model of a basic oxygen converter with data management (SMS Siemag, Technical University Dortmund), continuous improvement of the EAF process (Badische Stahl Engineering, Badische Stahlwerke), monitoring ladle degassing process after electric arc furnace tapping (VDEh Instutute of Industrial Investigations, Saarschmiede GmbH Freiformschmiede) and refractory ceramics for ingot production from high-quality steels (Steuler-KCH).
