The first article in this issue is "Study of structure, phase compositions and heat-physical properties of high-alloyed iron with globular graphite" by E. B. Ten, A. S. Drokin, S. T. Kaldybaeva. Structure, phase compositions and heat-physical properties of ЧЮ22Ш (ChYu22Sh) high-alloyed iron with globular graphite are examined. It is shown that iron is crystallizing as eutectic alloy where eutectic from α-solid solution and graphite makes the base of it's structure.
The second Russian-language article is written by B. E. Paton, V. I. Lakomsky, V. I. Galinich and D. D. Mishchenko; it observes steel production in electric arc furnaces. Proposed graphite electrodes contain solid core including additives with low electron working output; it allows to improve VA-parameters of arc and to increase electrode resistance.
H. B. Lüngen observed current state and prospects iron and steel production in Europe. K. Beskow, P. Vesterberg and E. Dupon investigated Granshot granulation process that is a cost-effective method of handling excess iron in integrated steelmaking at high capacity and low cost. When compared to pig casters or beaching, the process is superiour with respect tohealth, safety and environment and the end-product is easy to process.
Heat recovery from waste gas of electric arc furnaces was the theme of work of C. Born and R. Granderath. This article describes the iRecovery technology to recover this energy, especially targeting the reference project at Georgsmarienhütte in Germany. The result of this heat recovery is steam; it will be discussed why the question of steam usage is often more important and complex than the question of steam generation.
M. Sartor, D. Buchloh, F. Rögener and T. Reichardt presented investigation of analytical systems for stainless steel pickling solutions based on mixed acids. In this study the performance of conventional lab analysis and two commercially available measurement systems was compared using the same solutions taken from different stainless steel pickling lines in Germany and Spain. As a result, the applied calculation algorithms are sufficient to control pickling processes.
The problem of water usage in steel making were examined by P. Suvio, A. van Hoorn and M. Szabo. As part of a worldsteel Water Management survey, data was received from 29 steelworks, representing 8 % or about 111 million t of the global annual steel output.Nearly 82 % of the water is consumed by once-through cooling.
Economical section includes the paper ""Fair play rules" are required for providing compeptitveness of German and European iron and steel industry" by G. Endemann and U. Ratzek, analytical materials "Global iron and steel industry: demand is stable" by G. Krause and " Iron and steel industry should be more active" by E. D. Schulz.
