Huirui has completed several on-site laser repair cases of rolling mill arches. At present, Huirui’s technology and use effect of laser cladding repair of rolling mill arches have been generally

Hydraulic columns have been corroded by acid and alkaline media for a long time and operate in harsh, heavy-load, vibration, impact, and other environments. Their surfaces are easily prone to

The crystallizer is the core of the continuous casting machine. It is a device that injects molten steel into it, and after cooling, the outer layer of the molten steel

The crane roller is an important load-bearing component in the crane. It is made of Q345b. It is usually subjected to large shear stress during work. After long-term use, the

General looper rollers are prone to wear, peeling, fatigue cracks, roll sticking, and other problems during the hot strip rolling production process, resulting in parts being scrapped or even production

The valve stem is not only a moving part and a force-bearing part during the valve opening and closing process but also a sealing part. At the same time, it

Although the transmission shaft (flat head sleeve) has good hardness, it has poor impact resistance, cannot be restored after deformation, and has poor fatigue resistance, so it is easy to

Laminar cooling rollers are used in rolling mills for the transportation and laminar cooling of finished strips. During the transportation process of hot-rolled strips, laminar cooling rollers must not only
