Tungsten carbide (hard metal) Cemented carbides, or hardmetals as they are often called, are materials made by "cementing" very hard tungsten monocarbide (WC) grains in a binder matrix of a tough cobalt or nickel alloy by liquid phase sintering. Cemented carbides combine the high hardness and strength of metallic carbides (WC, TiC, TaC) or carbonitrides (eg TiCN) with the toughness and plasticity of a metallic alloy binder (Co, Ni, Fe), in which the hard particles are evenly distributed to form a metallic composite. Tungsten carbide is the most metallic of the carbides, and by far the most important hard phase. The more hard carbide particles are within the material, the harder it is but the less tough it behaves during loading; and, vice versa, significant increases in toughness are achieved by a higher amount of metallic binder at the expense of hardness. Within the field of engineering materials, cemented carbides play a crucial role as they combine high hardness and strength with good toughness within a wide property range, and thus constitute the most versatile hard materials group for engineering and tooling applications.   Typically a Tungsten Carbide Hard Metal can have a hardness value of 1600 HV, whereas mild steel would be in the region of 160 HV a factor of 10 lower. Although called a hard metal, Tungsten Carbide is actually a composite material with hard particles of Tungsten Carbide embedded in a softer matrix of metallic Cobalt . The chemical formula for Tungsten Carbide is WC.   Tungsten carbide is prepared by reaction of tungsten metal and carbon at 1400–2000 °C. Other methods include a patented lower temperature fluid bed process that reacts either tungsten metal or blue WO3 with CO/CO2mixture and H2 between 900 and 1200 °C. What are the properties of hard metal? Mechanical properties: Mechanical properties reflect the ability of a material to withstand a force of a certain type that, however, when applied, requires a more accurate definition. For clarity there are various types of force to which the resistance is opposed, depending on the load conditions; for hard metals the most important resistances within mechanical properties are compression resistance traction, abrasion, fatigue and bump transversal breakage .   Physical properties: Tungsten carbide has a high melting point at 2,870 °C (5,200 °F), a boiling point of 6,000 °C (10,830 °F) when under a pressure equivalent to 1 standard atmosphere (100 kPa), a thermal conductivity of 110 W·m−1·K−1, and a coefficient of thermal expansion of 5.5 µm·m−1·K−1.   Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers number of around 2600. It has a Young's modulus of approximately 530–700 GPa, a bulk modulus of 630–655 GPa, and a shear modulus of 274 GPa. It has an ultimate tensile strength of 344 MPa, an ultimate compression strength of about 2.7 GPa and a Poisson's ratio of 0.31.   The speed of a longitudinal wave (the speed of sound) through a thin rod of tungsten carbide is 6220 m/s.   Tungsten carbide's low electrical resistivity of about 0.2 µΩ·m is comparable with that of some metals (e.g. vanadium 0.2 µΩ·m).   WC is readily wetted by both molten nickel and cobalt. Investigation of the phase diagram of the W-C-Co system shows that WC and Co form a pseudo binary eutectic. The phase diagram also shows that there are so-called η-carbides with composition (W,Co) 6C that can be formed and the brittleness of these phases makes control of the carbon content in WC-Co hard metals important. Chemical properties: There are two well-characterized compounds of tungsten and carbon, WC and tungsten semicarbide, W 2C. Both compounds may be present in coatings and the proportions can depend on the coating method.   At high temperatures WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.   Oxidation of WC starts at 500–600 °C (932–1,112 °F). It is resistant to acids and is only attacked by hydrofluoric acid/nitric acid (HF/HNO3) mixtures above room temperature. It reacts with fluorine gas at room temperature and chlorine above 400 °C (752 °F) and is unreactive to dry H2 up to its melting point. Finely powdered WC oxidizes readily in hydrogen peroxide aqueous solutions. At high temperatures and pressures it reacts with aqueous sodium carbonate forming sodium tungstate, a procedure used for recovery of scrap cemented carbide.

Conferences mentioned specialization and special new enterprises, and many departments expressed support for the high-quality development of specialization and special new SMEs, and improved the ability and level of service specialization and special new SMEs...... This shows that specialization and special new SMEs Development has ushered in a policy vent. The "little giant" enterprise is sought after because of the powerful technological power behind it, of which energy cannot be underestimated.   To grow into a small giant enterprise must "repair internal strength" Only with unique skills can you have the right to speak. The "little giant" enterprises in Zhuzhou High-tech Zone either have a relatively high market share in the subdivisions, or have a great advantage in the research and development of related core technologies. In the field of industrial manufacturing, the sintering furnace is known as the "Pill Alchemy Furnace". When a good sintering furnace refines cemented carbide products, it can remove impurities, increase hardness, and become smoother and brighter, making cemented carbide products a veritable "industrial tooth". However, sintering furnace equipment has long been monopolized overseas, especially the most famous sintering furnace in Germany. How to open up the territory of "Made in China" among them, Zhuzhou Ruideer Metallurgical Equipment Manufacturing Co., Ltd. (referred to as “Ruideer”) has gradually grown into a national-level “little giant” enterprise after 10 years of “repairing internal strength”. Ruideer sintering furnace has successfully replaced the same type of imported products in the market, and is also exported to the US, Japan, Spain, Ukraine, Russia, Vietnam and other countries. The advantage of the Ruideer sintering furnace is that it has a decisive influence on important indicators such as the property change and uniformity of the calcined material. In 2020, the domestic market share of the company's main product pressure sintering furnace was 8.4%, ranking first in China.   Maintain sustainable development and innovation capabilities In industrial competition, the stronger the technological innovation ability, the greater the chance of winning. Ruideer has established a technology R&D department to maintain the company's sustainable development and innovation capabilities. It is responsible for the implementation of the company's key research and development projects, coordination and organization of product development, technology development and technical information collection. (Excerpt)

Warmly welcome experts and colleagues of the industry who are invited to the seminar of "cemented carbide" to visit Ruideer company for work guidance    On May 26th, the experts and industry colleagues of cemented carbide have visited Ruideer company. The general manager of Rudieer was introducing (see picture) and presenting the equipment for all the visitors.

         The development of the company is inseparable from the contribution of each employee. Thanks to all employees for their mutual growth and common growth. When work is busy, strengthen team building and enrich employees' spare time. Under the planning and organization of the personnel department of Ryder Company, employees and their families were gathered, and in October 2019, the beautiful seaside tour of Nha Trang, Vietnam was started.          Walking on the beach by the sea, from time to time, the waves are flapping on your feet, and from time to time, a seagull is showing off its beautiful dance to you, overlooking the blue sky and the endless sea, laughing and laughing all the way, feeling the gift of nature. Great view. During the period, they shared the experience of maritime amusement programs and mud baths, watched the rich underwater world, tasted the local Vietnamese specialties and seafood meals, conducted swimming competitions, surfing, diving and so on. Everyone was flying and playing. Almost! The handsome men and women dressed up in local costumes became a beautiful scenery. On the island of the night, it was that quiet, I could only hear the sound of the waves beating against the reefs, and I was isolated from the world. After dinner, I lay down on a chaise lounge, and a slight sea breeze blew, so clean and refreshing.         The 7-day trip was over soon, and everyone was still thinking about it and had a sense of lingering. In this beauty, it is indispensable to take pictures to save the moment. Through this trip, we have a better understanding of each other. At the same time, we also thank the company for providing a pleasant and unforgettable journey to each of our employees. Once again, we work together with the company to make progress together for the brilliant future of Ridel, and work together for the brilliant tomorrow of RUIDEER!
