Cemented carbide products
Steel bonded carbide products
The products are sold to European and American,Thailand, Vietnam, Taiwan over 50 countries and regions. With first-class production equipment, perfect detection means and skilled research team, our company has taken the lead in passing ISO9001:2000 Quality Management System certification in the same industry, and been recognized as “Provincial High-tech Enterprise”.
Since 1980s, our company has tackled key problems and researched cemented carbide roller rings matched with high-speed wire mills while introducing high-speed wire mills at home. The roller rings were applied to high-speed wire mills at home in 1989 and reached the international advanced level in the corresponding period; so far, they have been successively applied to high-speed wire mills of more than sixty iron and steel companies at home and abroad. Currently, our company has formed the annual productivity of 50,000 cemented carbide roller rings
Particularly, precision roller rings for sizing reduction frames, at the rolling speed of 120m/s, have been widely applied to the rolling of steel cords, steel strands, bearing steel, alloy welding wires and other high-carbon steel, alloy steel and common steel. At present, the matched rolling mills include MORGAN, DANIELI, SMS, POMINI, KRUPP and domestic high-speed wire mill units. the rod production line large-diameter combined rollers successfully developed in recent years feature high hardness, abrasion resistance,excellent rolled product quality, high comprehensive benefits, etc., receiving good praises from customers.
In 2002, our company introduced pure-carbon contact strip production technologies for electric motor vehicles from Russia. Through years of advantage taking and absorption, the technical indexes of the currently produced pure-carbon contact strips for electric motor vehicles have reached or surpassed national standards of Germany and Russia. Moreover, the pure-carbon contact strips passed the appraisal of Shandong Science and Technology Agency in 2006, which have been applied to many electric railway lines in China.
Cemented carbide rods, plates and precision cutting tools are mainly applied to automobile and motorcycle manufacturing industry, mould industry, bearing industry, aerospace industry, graphite electrodes, gear machining and other industries. Almost all the traditional materials difficult to cut can be smoothly machined by our company, particularly the materials with the diameter of 8mm-35mm can be milled and drilled to the best extent.
