The alliance was initiated by China's leading coal supply chain management service provider Tide Coal and Kailuan Group. The members include Shanxi Guoyang New Energy, Shaanxi Coal Group, Russia's East Siberian Coal Company, Anshan Steel, Baosteel, Beijing Railway Bureau, and Bank of China. Tangshan Branch etc.
According to reports, the mission of the coalition is to promote the development of the coal industry in China. Through the establishment of coal supply alliances and the introduction of supply management ideas and technologies, the alliance will accelerate the development and innovation of business models and business concepts in the coal industry and promote information exchange among member companies. , resource sharing, business cooperation, mutual benefit and win-win situation, leading the Chinese coal industry to a intensive, efficient, low-carbon road.
China's coal market is huge. Last year, coal production and consumption reached 3.05 billion tons and 3.13 billion tons respectively. In contrast, the utilization efficiency of domestic coal resources is overall low, and the pressure for energy conservation and emission reduction is very high. Jiang Ying, director of the Coal Research Institute of China Coal Research Institute, pointed out that in order to maximize the comprehensive utilization efficiency of coal resources, it is a general trend to build a supply chain system integrating production, purchase, coal blending, storage, and transportation.
According to Li Min, deputy general manager of Kailuan Group, China's coal industry has achieved historical rapid development in the past 30 years, but the coal market still has functional defects such as lack of public trading platforms and lack of efficient information exchange. This situation is incompatible with the rapid development of coal and related industries.
One of the member companies of the alliance, Shanghai Coking Co., Ltd. and the Kailuan Group have cooperated for decades. On behalf of Zhu Peiyi, the company’s representative, the establishment of a supply chain platform is very popular among coal producers and production users. She said that under the previous mechanism, the logistics of the coal industry has been very fragile and has long restricted the connection between supply and demand. In particular, there is still a great deal of conflict between the quality, variety structure, and production and demand of coal, which cannot meet the individual needs of users. "Through this alliance, we hope to eventually achieve an increase in the efficiency of the use of coal resources. But this is only a beginning, it also takes a longer process." Zhu Peiyi said.
A blended powder of tungsten carbide and Metal Alloy Powder can be used for laser cladding, a process used to deposit a layer of material onto a substrate using a laser beam. This blended powder is typically used as a feedstock material for laser cladding applications where high wear resistance and hardness are required.
Tungsten carbide is a hard and wear-resistant material that is commonly used in cutting tools, mining equipment, and other high-wear applications. It has excellent thermal conductivity and high melting point, making it suitable for laser cladding processes.
Metal alloy powders, on the other hand, are often added to the Tungsten Carbide Powder to enhance certain properties or tailor the characteristics of the final cladding layer. These metal alloys can include nickel, cobalt, chromium, or other elements, depending on the specific requirements of the application.
The blended powder is typically prepared by mixing the tungsten carbide and metal alloy powders in the desired ratio. This mixture is then fed into a laser cladding system, where it is melted using a high-power laser beam. The molten powder is rapidly solidified onto the substrate, forming a dense and wear-resistant cladding layer.
The resulting cladding layer can have excellent hardness, wear resistance, and thermal conductivity, making it suitable for various applications such as tooling, wear parts, and surface protection. The specific properties of the cladding layer can be adjusted by varying the composition and ratio of the tungsten carbide and metal alloy powders in the blend.
Overall, the blended powder of tungsten carbide and metal alloy powder offers a versatile and customizable solution for laser cladding applications, providing enhanced wear resistance, hardness, and other desired properties to the final cladding layer.
