Chernye Metally

The 12th issue of "Chernye Metally" journal (2013) contains 7 sections with 13 articles, and the section "Development of metallurgy in Russia and CIS countries" is the first as usual.

M. R. Konevskiy, E. T. Mukhambedyarov and S. V. Ryaboshuk from St. Petersburg State Technical University presented the article "Phosphorous ferroalloys. Production technology, grades and quality". They described the problem of termination of the specialized production of phosphorous ferroalloys (ferro-phosphorus and ferro-manganophosphorus) in blast-furnaces that has led to necessity of their replacement by electrothermic ferro-phosphorus in steelmaking and foundry processes. It is recommended to use FFE25-1 (ФФЭ25-1) grade during alloying of phosphorous steels, to lower the hazard of exceeding the preset phosphorous limits.

Manufacture of large-diameter tubes is observed by V. G. Ilyichev and Ya. E. Valavin from the Russian Scientific and Research Institute of Tube and Pipe Industries in Chelyabinsk.They considered technological features of formation of the cross section geometry of the billet perimeter in manufacture of large diameter tubes for the conditions of forming the marginal areas in a two-roll mill. Taking into account these considerations, the roll pass design for bending operation has been developed; it provides bending with increased shift of the vertical equatorial plane of a roll pass relating to the vertical symmetrical plane of tube billet.

The paper "Features of forming microstructure and mechanical properties of low-alloy steel using different routes of thermomechanical controlled process" by E. A. Goli-Oglu with colleagues from the Central Scientific and Research Institute of Ferrous Metallurgy (TsNIIchermet) named after I. P. Bardin and Vyksa Steel Works is devoted to influence of conditions of thermomechanical processing and accelerated cooling (TM+AC), low temperature thermomechanical processing and accelerated cooling (LTTM+AC) and low temperature thermomechanical processing (LTTM) on microstructure and morphology of microstructural components in the studied steels. Experiments have been conducted in the conditions of up-to-date heavy plate mill 5000 at Vyksa Steel Works.

Among translated articles, the paper by M. Hiebler, Ch. Bruckner from Siemens VAI Metals Technologies is rather interesting: it analyzed recent developments in optimizing process control in a BOF converter. The models of steel melting technological processes that were the objects of control and management are described. During industrial experiments at least 18 packages with models of technological process and measuring lances have been installed and the typical example of such installation for 160 t converter has been displayed.

Two papers in the section "Coke and By-Product Production" continues thematic publications in this area started if the issue No. 11-2013. They are devoted to state and development of cokemaking in Germany since 1912 and to business and engineering approaches to solving the ecological problems at cokemaking plants.

In the section "Continuous Casting", Ch. Klein, H. Rackel, W. Spies and T. Stark from SMS Siemag AG described the CSP plant of Essar Steel India at the Hazira location in the Indian federal state of Gujarat that started operation with two strands and will be extended to become the world‘s first three-strand CSP plant. It is concluded that combination of proved technological models and adjusting contours adopted to the mechanical equipment, as well as optimal "Plug and Work" testing preparing provided reaching the aimed results in very narrow time: 100 % productivity was achieved after 250 days of operation.

Increasing influence of of human beings on the environment substantiated the new approach to ecological estimation of production and to ecological balance forming. These aspects are examined in the paper by S. Neugebauer, M. Finkbeiner, W. Volkhausen, S. Mecke, G. Endemann in the section "Power Engineering and Ecology". Within the life cycle assessment model, the two main production routes for steel — the blast furnace route and the electric arc furnace route – are covered and equally modelled.

The issue also includes the sections "Metallurgy and Automotive Industry" and "Metallurgical History". The last one contains two memorial publications about foreign (by A. Schwarz) and national (by E. V. Tsirulnikov) metallurgists. As well, A. G. Zhurilo and D. Yu. Zhurilo presented the investigation about Henry Bessemer - if he really was the author of the famous steelmaking technology? There are different opinions among historians.
