This article describes the sequence of operations performed in an impulsive purging technology developed by the company TECHCOM. The technology was used to treat different grades of steel in a 120-ton ladle. Data presented in the article substantiate the effectiveness of the new technology. © 2012 Springer Science+Business Media New York.

The firm TECHCOM GmBH (Germany) together with MISiS (Russia) has developed and patented an immersion, closed-bottom nozzle FOSULIS for casting special steels. The FOSULIS nozzle is fitted with a "skirt" fastened to the bottom of the outside of the nozzle above the lateral outlet channels arranged in a fan pattern over the perimeter of the nozzle cross section. In this case, steel is fed into the volume of liquid metal within a mold by distributed streams, and axial flow is inhibited. The nozzle has been tested under production conditions for casting ball-bearing, rail, and structural steels. Use of the nozzle makes it possible to reduce steel contamination by a factor of two to three, and to improve macrostructure quality indices by a factor of two. Additional testing of the FOSULIS nozzle is planned in casting high-quality, high-carbon steel for cord with increased specifications for non-metallic inclusions and carbon segregation. © 2012 Springer Science+Business Media New York.

Product quality is analyzed for the pipe rolling plant with a continuous mill, and factors affecting product quality indices are established. Engineering conditions are considered providing the required level of metal mechanical properties. Steel melting and extra-furnace technology are adjusted. Heating temperature and deformation regimes during pipe billet and pipe manufacture are proposed. Heat treatment regimes are developed for pipe manufacture in accordance with specified standards. © 2014 Springer Science+Business Media New York.

In twist tests of high-tension bronzed wire (diameter 1. 55-1. 83 mm) produced by direct drawing from thermomechanically treated wire rod (diameter 5. 5 mm), lamination of the metal may be completely eliminated if the carbon and manganese content is reduced and chromium is added. © 2012 Allerton Press, Inc.
