Abstract

The invention discloses a high-strength wear-resistant closed steel frame and its processing technology. During the preparation, the surface of the alloy steel pipe fitting is cleaned by laser, and the surface of the alloy steel pipe fitting is cleaned by laser to remove the oxide film on the surface to improve the surface. Wettability, in the subsequent laser cladding process, the cladding liquid can be fully spread, and the subsequent wear-resistant layer is more uniform and dense, with fewer pores and better wear resistance; at the same time, the surface of the alloy steel will form a rough structure after laser cleaning , can improve its surface roughness, and further improve the adhesion of the thick laser cladding layer, so as to improve the comprehensive wear resistance of alloy steel. The process design of the application is reasonable, and the operation is simple. The prepared alloy steel pipe fittings form a wear-resistant layer on the surface, and the steel frame is obtained by splicing and installing. The wear-resistant layer can effectively improve the wear resistance and comprehensive mechanical properties of the alloy steel frame. The alloy steel frame It can be applied to multiple technical fields and has high practicability.

Description

technical field

[0001] The invention relates to the technical field of steel processing, in particular to a high-strength wear-resistant closed steel frame and its processing technology. Background technique

[0002] Steel frame generally refers to a structure composed of steel beams and steel columns that can bear vertical and horizontal loads, and is now widely used in industrial and civil buildings with long spans or high-rise or heavy loads; with the advancement and development of science and technology, steel is gradually In our daily life, the research on the strength, high temperature resistance, corrosion resistance and other properties of alloy steel has become a hot topic that we gradually pay attention to.

[0003] Aiming at the wear resistance of steel profiles in the prior art, many related patents or documents have been disclosed, but the common method is to coat the surface of steel profiles with a wear-resistant coating, which has high cost and complicated pr...
