Chernye Metally

The No. 4 issue of "Chernye metally" journal is opened by the large section "News of Metallurgical Companies".

The next section "Development of Metallurgy in Russia and CIS" includes 3 publications.

E.V. Shilnikov (Electrostal Steel Works) has presented examination of the melting technolofy for alloy steel via remelting of wastes with blowing of the 20 t bath with oxygen. The pilot melts with taking metal samples and measuring the bath temperature in the beginning, middle and end of oxidizing melting period have been conducted in order to determine kinetic regularities and constants.

The paper by N.A. Kozyrev and A.A. Umanskiy (Siberian State Industrial University) and D.V. Boykov (EVRAZ United West-Siberian Metallurgical Works) is devoted to the new technology of ladle treatment of rail steel with increased duration of inert gas (argon) blowing in order to decrease oxygen concentration and improve the steel properties. The technology has been tested on 190 regular melts of E76Ф steel and 15 pilot melts with durable blowing.

D.Ty. Zvonarev et al. described development of the mathematical model for forming of strip billet for quality improvement of large diameter welded tubes. The results of investigation allow to determine the depth of punch lowering, and on the base of this value to define the required geometrical parameters of an actual radius and height of flange bending.

The translated section includes the article written by Austrian metallurgists about development of the technology and equipment for innovative dry gas cleaning in iron and steel production by Siemens VAI Metals Technologies. Another material is devoted to 25th anniversary of commercial operation of the CSP process for combined casting and rolling.

D. Karl from Fraunhofer Institute has presented the developed control system in wire production that allows to realize monitoring and fixing of surface defects at 10 m/s speed. The paper by A. Klostermeier from Eltro company is also devoted to quality control. He has examined possibilities of burning analysis for checking the properties of iron and steel products and described standard approaches for work with such analyzed.

The issue also contains analysis of the new European power engineering policy (by H.J. Kerkhoff) as well as large block of economical information.
