A few days ago, the atmosphere at China Coal Zhangjiakou Coal Mining Machinery Co., Ltd. was filled with excitement and celebration. The company hosted a ribbon-cutting ceremony for the "three-machine set" heavy coal mining equipment, which was contracted to South Kuzbass Coal Company in Russia. The contract value reached 180 million yuan, marking a significant milestone for China's coal machinery industry.
This advanced set of heavy-duty coal mining equipment was jointly developed by Zhangjiakou Coal Machinery Co., Ltd. (a subsidiary of China Coal Group), Beijing Coal Machinery Co., Ltd., and Xi'an Coal Mining Machinery Plant. It consists of three key components: a coal mining machine, a scraper conveyor, and hydraulic supports. Designed with large production capacity, high reliability, good versatility, and cost-effectiveness, this equipment represents a breakthrough in China's coal mining technology.
This is the first time that China has exported complete sets of coal mine machinery and related technologies abroad. It also marks an important step in the international expansion of China Coal Zhangjiakou Coal Mining Machinery Co., Ltd., following the acquisition of chain technology from the British company Parsons. This move demonstrates the company’s growing global presence and technological capabilities.
South Kuzbass Coal Company is Russia’s largest coal enterprise, and the introduction of top coal mining technology represents a major transformation in Russian coal mining history. The successful export of this heavy machinery not only highlights China’s growing influence in the global coal industry but also paves the way for broader international market entry for Chinese heavy machinery manufacturers.
With this achievement, China is no longer just a producer of coal equipment but is becoming a key player in supplying advanced mining solutions worldwide. This event signals a new era of cooperation between China and Russia in the energy sector and sets a positive example for future international collaborations in industrial technology.
Tungsten Carbide Roll Rings
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.
