Grinding Technology of A588 Weathering Steel Plate

A588 weathering steel plate is a structural steel resistant to atmospheric corrosion. Compared with ordinary carbon steel, it has higher corrosion resistance and better durability, and is widely used in various buildings. The advantages of A588 weathering steel plate make it the material of choice for a variety of structural applications.

The corrosion resistance of A588 weathering steel plate mainly depends on the content of chromium, nickel, copper and the oxide on the surface. The content of these elements in the alloy affects the stability of the oxide film, thereby affecting the corrosion resistance. A588 weather-resistant steel plate also has good welding performance, and the structure can be welded by conventional welding process.

The grinding technology of A588 weathering steel plate is an important criterion for the guarantee of quality during the processing and application process. The grinding process needs to be carried out in an environment with a certain temperature and humidity and a certain air pressure. It is necessary to use the qualified abrasive grinding wheel, and to avoid the burning phenomenon of steel at the grinding process due to low temperature and satisfy the requirements of welding performance and surface finish.

During the grinding process, the metal particles produced by grinding are easy to adhere on the surface of metal to form metal chips, and the adsorption of abrasive grains number on the metal surface is easy to reduce mechanical performance and corrosion resistance of the steel surface. Therefore, the grinding process of A588 weathering steel plate should be carried out with pressure and no lubrication. In the grinding process, it is necessary to use a cleaning fluid with strong cleaning function to clean the metal surface.

The vibration between the grinding wheel and A588 weathering steel plate in the grinding process should be avoided, and the grinding wheel should be rotated at a constant speed and at a no-load speed for a certain period of time. At the same time, attention should be paid to the cooling, which can not only reduce the temperature of the grinding zone, but also improve the grinding and cutting performance.

At the same time, attention should be paid to the selection of grinding parameters such as grinding pressure, grinding current and grinding speed, so as to avoid regrinding and reduce the machinability of A588 weather-resistant steel plate. In addition, the grinding force and radial grinding force also need to be optimized to ensure uniform grinding and good material surface quality.
