Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a surface grinding device for a weathering steel plate. Background Art

[0002] Weather-resistant structural steel plates are atmospheric corrosion-resistant steel plates, which are low-alloy high-strength structural steel plates. According to their main characteristics, they are divided into high-weather-resistant structural steels and weather-resistant steels for welded structures. The use of high-weather-resistant structural steels is due to their better atmospheric corrosion resistance than that of welded structural weather-resistant steels. They are mainly used for bolted, riveted and welded structural parts for vehicles, containers, buildings, towers and other structures. The welding performance of welded structural weather-resistant steels is better than that of high-weather-resistant structural steels. They are mainly used for welded structural parts for bridges, buildings and other structures. Grinding processing can remove oxide scales, stains and other irregular parts on the surface of the steel plate, making the surface of the steel plate smooth and flat.
