March 20 at JSC "Ural Steel" was launched air separation plant CERBA 30 CCC and hot testing of vacuum plant in EAF steel.
Starting a new process equipment will expand the range of products produced by the enterprise, and improve the quality and competitiveness.
Vacuum treatment — one of the most effective ways to secondary treatment of liquid steel. It provides a significant reduction in the metal content of dissolved oxygen, nitrogen and hydrogen, and its contamination by nonmetallic inclusions. Improving the quality of steel leads to a decrease in the total sorting rolled plate for surface defects can reduce the consumption of electricity in the shop section rolling mill by eliminating modes antiflocculation in thermal processing furnaces.
With the construction of a new electric furnace shop vacuum vessel per year will be able to handle up to 1.2 million tons of liquid steel used for the production of strips, rolled plates, billets and structural steel, and cast round billets. The setup allows Novotroitskie metallurgists to produce strips of steel grade X80-X100. The total cost of the investment amounted to 705 million rubles. The project was implemented over a period of 3 years. Supply of technological equipment from Siemens VAI has implemented in June 2010.
"The use of the world’s best technology has always been one of our priorities. Evacuation began to allow the company to produce high-class products that meet the most stringent requirements of the consumers, "- said General Director of the Criminal Code" METALLOINVEST "Eduard Potapov.
Part of the largest investment project "Ural Steel" to modernize the oxygen compressor plant was the launch of an air separation unit (ASU number 5). His goal — to fully cover the needs of the structural units of the plant in vysokachestvenny liquid and gaseous air separation products, including argon. The total project cost was $ 2,513 million. The period of its implementation — 5 years. The plant is designed to produce 30,000 cubic meters of industrial oxygen per hour. Provide high purity oxygen — 99.7%, significantly higher than with the old type of installations. With the commissioning of the new air separation plant will cease to combine technical experience a shortage of oxygen.
The new unit is equipped with modern equipment, all the processes of administration and control ASU computerized. Supply and installation company implemented a "Cryogenmash". Infrastructure facilities were constructed in-house "Ural Steel".
