Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically to a rust removal device for steel structure processing. Background Technology

[0002] In the field of steel structure processing, rust removal treatment of steel surface is a key link to ensure the quality and service life of components. During storage, transportation and processing, steel is prone to forming an oxide rust layer due to environmental humidity, oxygen contact and other factors. If it is not removed in time, it will directly affect the quality of subsequent painting, welding and other processes, resulting in poor coating adhesion, reduced welding strength and even structural safety hazards.

[0003] Currently, rust removal of steel structures mainly involves manual hand-held grinders, laser rust removal machines, or sandblasting rust removal machines. This method is labor-intensive, inefficient, and generates a large amount of dust and noise pollution. Furthermore, the rust removal effect is greatly affected by the operator's skill level, making it difficult to guarantee the uniformity of surface treatment. Therefore, we propose a rust removal device for steel structure processing to solve the above problems. Utility Model Content
