Hardfacing is the process of surface hardening of wear-resistant parts. Hardfacing welding technology is often used in the production and processing of cemented carbide. Hardfacing welding technology can protect hard alloy wear-resistant parts well and prolong the service life of wear-resistant parts at the same time. Today, Sidi Xiaobian will share with you the application of hardfacing surfacing technology in various fields. 1, the oil drilling industry hard surface welding technology application drill bit is often used in the oil drilling industry rock-breaking tools, its performance directly affects the drilling speed, drilling quality and drilling costs. In the face of the harsh environment of the oil drilling industry, the drill bit is often prone to corrosion, poor impact resistance, easy to break, and can not meet the requirements of drilling conditions. Therefore, it is necessary to select spherical cemented carbide and diamond with good wear resistance as the tooth surface strengthening material, and use surfacing welding process to complete the surface strengthening, and improve the wear resistance and impact resistance of the drill surface by welding the particle casting cemented carbide on the drill surface. 2. The application of hardfacing technology in the steel industry We know that the working environment of wear-resistant parts in steel plants is very harsh. Its production process is extremely high temperature, hot and cold alternate frequently, the use of wear-resistant equipment will accelerate wear, not only will increase the maintenance cost of the steel plant will also increase the labor intensity of the staff. Therefore, most steel plants need to adopt hard surface surfacing technology, which is to surfacing hard alloy on the surface of scrapped rollers and pile them up to the original surface size of the rollers. This can not only reduce production costs, but also shorten the recovery time and increase the amount of steel by 8 to 10 times, which is very economical and reasonable. 3. The application of hard surface surfacing welding technology in power plants is the main force in China's thermal power generation. It can be said that thermal power generation is the leader in the domestic power industry, which is also inseparable from China's rich coal resources. Thermal power generation requires a large amount of pulverized coal, and a vertical mill is used to pulverize the pulverized coal. However, due to the impact of coal quality, the impact of the opposite mill is also very serious. If running for a long time, it will make the grinding roller surface appear groove-like wear, grinding disc surface will also appear relatively large ring groove, making the coal mill work efficiency is getting lower and lower, thereby increasing energy consumption. At this time, hardfacing welding technology is used to surfacing the surface of the grinding roller and the grinding disc, so that the surface of the wear-resistant part forms a wear-resistant layer, which has a good protective effect on the grinding roller and the grinding disc and can extend its service life. Xidi Technology Co., Ltd. has a variety of surface strengthening technologies, including plasma surfacing, supersonic spraying, gas shielded welding, flame cladding, vacuum cladding, solid/salt bath boronizing, thermal diffusion hardening and other aspects have rich experience, to provide customers with solutions to various difficulties.
