The project passed the product appraisal organized by the Department of Science and Technology of Anhui Province in April this year. The appraisal committee unanimously believed that this series of products has independent intellectual property rights, which fills domestic gaps and is at the leading level in the country. The study of the project also produced two utility model patents: First, the tractor's semi-automatic traction pin mechanism; the second is the transverse cylinder steering bridge with a disc brake. This series of products was sold in batches in May 2007, after approximately one year of small-scale trial sales. At present, China Railway Express has already ordered several orders for "Heli" 25-ton electric tractors. The market prospect of "Heli" 20 to 25 tons electric tractors is very broad.
Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
