Production precautions for wear-resistant elbows:

1.It has excellent wear resistance and can be used continuously10More than one year

According to the determination of the Powder Metallurgy Research Institute of Central South University of Technology, the wear resistance of special ceramics is equivalent to that of manganese steel266It is made of high-chromium cast iron171.5It has excellent wear resistance. The application of wear-resistant elbows in the powder-making system has greatly reduced the wear of the equipment. Based on over ten years of on-site operation experience, the service life is at least10For more than one year, reduce the frequency and cost of maintenance.

2.The inner lining ceramic has high strength, high hardness and light weight

The Rockwell hardness of the corundum ceramics produced by our company has been determined by the Shanghai Institute of Ceramics, Chinese Academy of SciencesHRA80-85Its hardness is much higher than that of wear-resistant steel and stainless steel. Its density is only half that of steel,The weight of ceramic elbow pipes is only that of wear-resistant steel elbow pipes1/3It is convenient for installation and replacement.

3.It is firmly attached and has good heat resistance and corrosion resistance

Wear-resistant elbow

Ceramic sheets are adhered to the inner wall of the elbow pipe using high-temperature inorganic adhesives. This adhesive was jointly developed by our company and the State Key Laboratory of Fine Ceramics of Tsinghua University. It has strong adhesive force, high temperature resistance and aging resistance, and can ensure that it will never fall off. Boiler manufacturers such as Dongfang Hitachi all use this adhesive for ceramic mounting inside burners. The mounting process is simple and the reliability is extremely good. Ceramics are inorganic materials that do not undergo oxidation or rusting and are resistant to acid and alkali corrosion.

4.The inner wall is smooth and does not clog powder materials

The ceramic tiles are sintered at high temperatures, resulting in a dense structure. After grinding and deburring treatment, the surface is smooth. The mounting process is strictly in accordance with«Operation Instruction Manual»Proceed to ensure a smooth transition of the ceramic tiles and that the height difference does not exceed0.5mmAfter installing the ceramic, the inner wall of the elbow pipe is smooth and flat, without clogging the powder.
