The inserts LLC VIRIAL successfully tested at JSC Severstal

 

Tests of the cutting tool, LLC "VIRIAL", RUSNANO project company, has successfully completed in Cherepovets at JSC "Severstal". Using inserts from the composite based on the cubic boron nitride can process per unit time is 3-4 times more rolls compared with previously used tool. In this case, the expert valuation experts "Virial" by 40% reduces the cost of processing one the roll.

Mill rolls — cylinders made of solid cast iron grades in diameter from 240 to 590 mm and a length of 1.7 to 3.6 m — key details of the steel rolling mill. Their performance depends directly on the quality of the main products of the metallurgical enterprise. In the factories of "Severstal" is spent annually over 1000 rolls, each roll is subjected to repeated treatment with a cutter.

The trials involved cutting inserts made of alloy, specially created in "VIRIAL" for the treatment of materials cast iron section rolling rolls. The use of plates in the CBN provided them with a high impact and temperature resistance and long service life. Development of the "Virial" — which has no analogues in the Russian double-layered plate on a carbide substrate — showed better resistance to rough machining of shafts. During the tests were picked and plate are made of special cutting angles are optimized and processing modes rolls.

According to test results signed an agreement to supply the inserts LLC "VIRIAL" to OJSC "Severstal", in which the two parties have already shipped tool.

 

Established in 1991, the company "VIRIAL" manufactures parts and components based on ceramic and metal materials and takes about 40% of the Russian market of wear-resistant parts for submersible oil pump, mainly competing in this market to foreign manufacturers.
