Analysis of China Carbide Industry
Carbide with high hardness, wear resistance, strength and toughness is better, heat, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature also remained unchanged , At 1000 ℃ is still very high hardness. Carbide is widely used as cutting tool material, such as turning tools, milling cutters, planers, drill bits, boring knives, etc. It can also be used for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel. Heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to process materials. Now the cutting speed of new carbide cutting tools is equal to hundreds of times that of carbon steel. Due to the implementation of China's macroeconomic policy of sound and steady, the rapid growth of the national economy, demand for carbide is also high growth.
Carbide on the market in China to foreign high-performance high-precision carbide grinding blade-based coating. These alloy blades are often associated with carbide tools and CNC machine tools into China. The use of imported CNC machine tools and CNC cutting tools need to continue to add wear and tear of the carbide blade. With the rapid development of China's auto industry, as well as the field of mechanical processing of imported CNC machine tools, the increasing number of processing centers. The demand for imported high-performance high-precision abrasive coating blade is also increasing, although Zhuzhou BTCarbide Precision Carbide Co.,Ltd to domestic enterprises to provide a large number of high-performance high-precision abrasive coating blade, but blade varieties, quality and foreign advanced level There is a certain gap, especially in the domestic CNC machine tools, machining centers and CNC tool production is still relatively backward case, with the supply of alloy blade with these closely related to the situation, but also to foreign advanced carbide production enterprises with technical superiority And related favorable conditions, so that these products in China won the market.
Carbide industry has entered the global mature stage, the market competition is fierce
Currently there are 600-700 manufacturers of carbide (not including China's domestic small and medium-sized enterprises). The world's leading manufacturers of hard alloy: Sandvik Sweden, the United States Kennametal companies, Israel's Iscar Corporation, Japan's Mitsubishi Matetials and ToshibaTungalloy companies, Luxembourg ceratizit companies.
Globally, the cemented carbide market is basically in a relatively saturated state, the industry has entered a mature stage, the market competition is fierce. Global production of cemented carbides mainly includes the United States, Russia, Sweden, China, Germany, Japan, the United Kingdom and France. The output of cemented carbides has been increasing steadily in recent years, but the growth rate is slowing down. It is estimated that in 2015 the global cement industry tungsten total consumption of more than 50,000 tons, cemented carbide production is about 70,000 tons, an increase of 2%. According to the China Nonferrous Metals Industry Association, China is the world's largest cemented carbide production countries, carbide production accounts for about 38% of global production, followed by 26% market share in Europe.
The 10th Shanghai International Carbide Exhibition
China is the world's important raw material carbide origin, but also an important base for carbide production and consumption of the market. Carbide because of its excellent characteristics, a large number of applications in the mold machine tools, petrochemical, mineral machinery, automotive, aerospace, military and other fields. With the development and implementation of China-made, the future of carbide is to high-performance, high-precision, high value-added direction of development and extension. Carbide industry as a service platform for the exhibition, the Shanghai International Carbide Exhibition has been to vigorously promote technological exchanges, improve the original innovation capability, the key technological innovation capability and system integration capabilities as its mission to help industry sustainable development.
After the storm, Shanghai International Carbide Exhibition has become one of China's major carbide industry event, a well-known enterprises at home and abroad to display the main platform, the industry procurement, gathering information, looking for channels of choice for the show. As a global professional exhibition based in China, PM CHINA exhibition scale, the exhibition expanded year by year, with its industry accumulation thickness and brand strength and professionalism, for the development of powder metallurgy industry to provide strong support, in this, PM CHINA group The committee sincerely invite the majority of the industry, to visit the 10th anniversary of the PM CHINA exhibition site, to participate in the industry together, "gather wisdom."

3DP technology to manufacture carbide molds
Carbide, a composite of fine grained hardmetals made of bonded metal hardmetals, is a very hard material that is often used in the mechanical and automotive engineering and building materials industries. Carbide die is the life of steel mold ten times or even several times, carbide mold high hardness, high strength, corrosion resistance, high temperature and the expansion coefficient is small, generally using tungsten cobalt carbide.
Carbide hardness is too high, the conventional processing is grinding, using a diamond wheel, polished with a fine point of the wheel. The hole can only be used in general electric erosion machining, such as EDM, or wire cutting, or even use electrolytic grinding technology.
Researchers at the Fraunhofer Institute in Germany have succeeded in producing carbide dies using 3DP adhesive jet-jet 3D printing technology. 3D Science Valley has learned that these 3D printing carbide dies have a much greater geometrical trough freedom than conventional methods to produce more complex geometries.
As experts in the field of cemented carbide, Fraunhofer Institute for decades for the manufacture of ceramic cemented carbide molds by uniaxial or cold isostatic pressing, these materials are mainly made of tungsten carbide. Despite the high reliability of these molds, the Fraunhofer Institute still faces the problem of the limitations of traditional manufacturing processes when creating complex geometries, such as internal helical or tortuous cooling ducts.
Now, with 3DP prints of cemented carbide powder, the Institute can easily create complex designs. 3DP is an adhesive jet printing technology in which powder particles of ceramic hard materials, including tungsten carbide particles, are printed by laminating layers of cobalt, nickel or iron. This adhesive material is not only an adhesive between the powder layers, but also allows the product to have good mechanical properties and can produce fully dense components, and even can be selectively adjusted flexural strength, toughness and hardness.
Subsequent treatments, including sintering, yielded the compactness of cemented carbide molds consistent with traditional processing methods. The Fraunhofer Institute believes that this process has a broader scope for expansion, including the uniform distribution of tungsten powder into the cemented carbide, which can be used to produce high-performance cutting tools.
Carbide in addition to mold, a wider range of uses is used as a tool material, such as turning, milling cutter, planer, drill, boring tool for cutting iron, nonferrous metals, plastics, chemical fiber, graphite, glass, Stone and ordinary steel, can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to process materials. The future, 3DP technology will be applied to the field of carbide cutting tool production, perhaps for the production of small quantities of special tools it is not impossible, 3D Science Valley will continue to focus on.
