Chernye Metally

"Chernye Metally" journal No. 5-2013 has been published.

Conventional section "Development of metallurgy in Russia and CIS countries" is presented by three different materials.

Peculiarities of the process of alloying steel by nitrogen at plasma arc remelting in large-sized furnace are considered in the article “An experience of producing high-nitrogen non-magnetic stainless steels” by O. S. Muradyan and I. A. Galikeev. It is shown that nitrogen content in remelted metal increases at the decreasing of total gas pressure inside the furnace. Compositions and mechanical properties of stainless austenite high-nitrogen steels produced using plasma arc remelting furnace, induction furnace in complex with centrifugal casting machine and ladle furnace with preliminary vacuum-oxygen decarburisation are presented.

The report about the 7th International conference "Stainless steel price 2013" is presented by L. Khazanov from “Metal Supply and Demand” journal.

The third material – coloured insert – is devoted to 240th anniversary of Omutninsky Metallurgical Works – one of the oldest Russian iron and steel works in Ural region.

The translated section "Iron and Steel Making" includes 2 publications.

R. Fandrich, J.-T. Ghenda, H. B. Lüngen from the Steel Institute of VDEh presented the report “Quality and acceptability of raw materials, power engineering efficiency - the requirements for iron and steel production” at the seminar "Raw materials and energy as the base for effective metallurgical process" that was devoted to the problems of deterioration of quality of raw materials as a serious problem of blast furnace practice, as well as to alternative processes of ironmaking. Other actual problems - influence of alloying elements on steelmaking, supply of alumina-bearing raw materials for refractories production were also discussed.

Consistently good results with commissioning vacuum plants were analyzed by A. Pezza, M. Abek, M. Hein, T. Wieting from Siemens VAI Metals Technologies. It was shown that vacuum plants are increasingly being installed in so-called mini mills in addition to integrated steelworks and stainless steel production. This article deals with the design and results achieved with the recently commissioned VD plant at SSAB in the USA, the VOD plant at Tisco in China and the RH plants at CSA in Brazil and Zhangjiagang in China.

Three articles are included in the section “Power Engineering and ecology”.

Specialists from Vienna University of Technology and Siemens VAI Metals Technologies observed the concepts and simulation results for heat recovery plants based on thermal energy storage systems for electric arc furnaces. Different systems were compared to each other based on transient simulations using the commercial process simulation software APROS (Advanced PROcess Simulator).

F. Schulz examined the projects at ArcelorMittal Germany sites with approach of investing with consistency in energy efficiency projects. He is sure that production sites of Arcelor-Mittal in Germany can be proud to be part of the most energy efficient steel production sites in the world.

U. Ratzek, special editor of “Stahl und Eisen”, substantiated that, owing to modernization of the existing units, it became possible not only to increase power engineering efficiency and productivity, but also to optimize production program, consumption of materials and energy carriers. The paper also examines the strategies of reliable data processing at the enterprises of iron and steel industry.

Taking into account current disputes about future of steel and other metals, E. Eichler in his paper confirmed that ThyssenKrupp trusts in steel as basic material for industry and is focused on the highgrowth premium flat carbon steel segment.

Economical and historic sections are presented, as usual.
