The punching elbow is a kind of good elbow, which is widely used and popularized in different fields and industries, and has been applied and popularized in different degrees. The stamping elbow is made of sheet material with the same material as the pipe material, and the stamping die is stamped into a half circular elbow. Then the two half ring elbow is assembled and welded. The welding of the stamping elbow needs to be produced and processed according to a certain process. In general, the higher the carbon content in the punching elbow, the greater the hardness, the higher the strength, but the lower the plasticity. Mainly refers to the mechanical properties of the carbon content in the steel, but generally do not add a large number of alloy elements of steel, sometimes also known as carbon steel or carbon steel. Carbon steel is also known as carbon steel, which refers to an iron - carbon alloy with a carbon content of less than 2% of WC. According to the long term production, the stamping elbow is summed up in many failures, and a relatively reasonable and scientific new experience is added, adding a certain amount of rare earth elements to improve the alloy quality of the steel. Also play a role in grain refinement; forming a protective film on the surface of boron carbide, adding a certain amount, can control the hardness in the range of HRC45~65, and solves the contradiction between
hardness and wear-resisting bend welding between the wear resistance is high, in the practical application of wear resistant materials and it cannot be other than.
Performance characteristics of stamping elbow
1. inner lining ceramic is high in strength, high in hardness and light in weight
The hardness of the corundum ceramics produced by our company is HRA80-85 by the Shanghai Institute of Chinese Academy of Sciences. The hardness of the corundum is much higher than that of the wear-resistant steel and stainless steel. The density is only half of the steel, and the weight of the ceramic elbow is only 1/3 of the wear-resistant steel elbow, which is easy to install and replace.
2. fasten fastness, heat resistance, good corrosion resistance
The ceramic sheet is mounted on the inner wall of the elbow with high temperature inorganic binder. The adhesive is developed by the State Key Laboratory of fine ceramics, Tsinghua University. It has strong adhesion, high temperature resistance and aging resistance. It ensures that it will never fall off. The process is simple and reliable. Ceramics are inorganic materials, no oxidation corrosion, acid alkali corrosion resistance.
3. excellent wear resistance, continuous use of more than 10 years
The wear resistance of special ceramics is 266 times that of manganese steel, 171.5 times of high chromium cast iron and excellent wear resistance. The application of wear resistant elbow in pulverizing system has greatly reduced the wear of equipment. According to the operation experience of more than ten years, the durability time is at least 10 years, and the frequency and cost of maintenance are reduced.
