Description

Steel structure surface quenching device Technical Field The utility model belongs to the technical field of steel structure quenching, and particularly relates to a surface quenching device for a steel structural member. Background In modern industrial production, steel structures are widely used in numerous fields of mechanical manufacturing, automotive industry, aerospace, etc. However, these fields have increasingly stringent performance requirements for steel structural members, which require not only good strength and toughness, but also high hardness, wear resistance and certain fatigue resistance on the surface thereof to meet the use requirements under complex working conditions. Traditional heat treatment modes, such as integral quenching, can improve the integral hardness of the steel structural member, but often lead to larger deformation of the part, increase of subsequent machining allowance, even influence on the dimensional accuracy and mechanical performance of the part, and are not suitable for some steel structural members with complex shapes and high accuracy requirements. The surface quenching technology can effectively solve the problem, and the surface of the steel structural member is rapidly heated and cooled to form a hardening layer, and the inside of the steel structural member still has better toughness, so that the deformation and residual stress are reduced while the surface performance is improved, and the product quality and the production efficiency are improved. At present, the existing surface quenching device for the steel structural part has some defects.
