Product Introduction
Silicon Carbide Sand is a part of Silicon Carbide . It is most widely used in the modern C, N, B, and other non oxide high technical refractory raw materials. Silicon carbide hardness is very high, the Mohs hardness is a magnitude 9.5, the second only to the world's most hard diamond (10). It with excellent thermal conductivity, is a semiconductor, high temperature resistant to oxidation. Low grade silicon carbide (containing about 85 per cent of the SiC) is an excellent deoxidizing agent, it can accelerate the speed of steel-making, and easy to control the chemical composition, improving steel quality.
The silicon carbide has Green Silicon Carbide and Black Silicon Carbide. Black Silicon carbide used for semiconductor, lightning rod, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutch, diesel particulate filter, filament pyrometer, ceramic film, cutting tools, heating elements , Nuclear fuel, jewelry, steel, protective gear, catalyst support and other fields.

It is understood that at the beginning of 2011, the Russian metal processing machine has a reserve of 140,000 pieces. In 2009, the import share of this product fell by 16.8%. In 2010, the import volume surged to 606,000 pieces, and the import volume in 2011 increased to 673,000 pieces.
Russia's metal processing machine tool output fell the most in 2009, down 58.5% year-on-year. Production in 2010 increased by 33% year-on-year to 4,200. In 2011, the output of Russian metalworking machine tools increased to 5,100 pieces.
It is predicted that the production of Russian metal processing lathes will continue to recover from 2012 to 2016, with an average annual increase of 10%, and the output will increase to 8,200 at the end of 2016.
Russian Prime Minister Dmitry Medvedev pointed out at the Russian machine tool development conference that the demand for machine tools in Russia's domestic market is very large. By 2015-2017, the annual demand for the defense industry alone will reach about 100 billion rubles (about 1 US dollar). 32 rubles). He said that the demand for Russian machine tools increased by 13% in 2012 to reach 3 billion US dollars. In general, the development of Russian machine tool industry is far from ideal. Russia's metallurgical processing equipment ranks more than 30 in the world, and the machine tool manufacturing industry accounts for more than 30. The proportion of GDP is only 0.03%, while China's indicator is close to 1%. Currently, 90% of Russia's machine tools are imported. Mei pointed out that Russia should change the current status of the machine tool industry, speed up the modernization of defense industrial enterprises, increase the supply capacity of modern technology equipment, and concentrate funds to expand the production capacity of machine tools within the framework of federal special planning.
Russian machine tools rely on imports urgently need to expand production capacity
Abstract According to the survey of the current situation and prospects of the Russian metalworking machine tool market organized by Intesco Research Group in 2012, imported metal processing machine tools in the Russian market dominated. &nb
