[0002] With the development of my country's economy, people's living standards have also increased significantly. With the improvement of living standards, grinding equipment is widely used in modern cement and electric power. In grinding equipment, grinding rollers are important components for crushing materials. At the same time, grinding rollers The safe operation of the company determines the realization of the benefits of this enterprise. However, when the surfacing welding is completed at this stage, the surface of the weldment cannot be protected and polished, which often leads to oxidation and cracks in the weldment during transportation and placement. At the same time, due to the failure to smooth the surface of the weldment, the surface of the weldment will be too rough, which will affect the use efficiency of the weldment

Embodiment Construction
[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below.
[0024] A surface treatment process for roller surfacing, the surface treatment process steps are:
[0025] (1) Preheating treatment of the weldment. After the surface cleaning is completed, the weldment is placed in the preheating furnace for preheating treatment.
[0026] (2) Welding surfacing processing, and then place the preheated weldment on the rotating shaft in the surfacing machine for rotary surfacing processing. The surfacing temperature during surfacing processing is 120-135 ° C.
[0027] (3) Cooling and annealing heat treatment after surfacing welding. After the surfacing welding is completed, the weldment is subjected to cooling and tempering heat treatment, and then cooling and cooling treatment is performed.
[0028] (4) Post-welding surface treatment, the weldment after annea...

The invention aims at providing a surface treatment technology for grinding roller surfacing. The surface treatment technology comprises the first step of weldment preheating treatment, the second step of weldment surfacing machining, the third step of cooling and annealing heat treatment after surfacing and the fourth step of surface treatment after welding, wherein surface machining is conducted in three steps of fine grinding machining, water spraying and cleaning treatment on a weldment and placing of the cleaned weldment into oil for rapid rinsing, and the surface smoothness of the weldment is improved. Meanwhile, cleaning and grease rinsing are conducted on the surface of the weldment, the surface of the weldment can be better isolated from air, and weldment surface oxidization and fracture are prevented.
