In steel production, rolls are key consumable parts in the steel rolling process, and their performance and quality directly affect the efficiency of steel rolling and the quality of products.
With the continuous development of the steel industry, the performance requirements for rolls are getting higher and higher, and traditional roll repair and strengthening methods can no longer meet the needs.
As an advanced surface treatment technology, laser cladding technology can form a cladding layer with high hardness and good wear resistance on the surface of the roller, significantly improving the wear resistance of the roller.
Compared with traditional surface treatment methods such as surfacing and electroplating, the laser cladding layer has higher hardness and better wear resistance, which can effectively resist wear during steel rolling and extend the service life of the roller.
Laser cladding technology can accurately control the thickness and shape of the cladding layer, so that the surface flatness and finish of the roller are significantly improved.
This helps to improve the surface quality of rolled steel products and reduce product quality problems caused by roller surface defects.
Repairing worn rolls through laser cladding technology can avoid the scrapping and replacement of rolls, greatly reducing production costs.
At the same time, the laser cladding layer has a long service life, which reduces the maintenance and replacement frequency of the rolls, further reducing production costs.
Repair and strengthening of backup rolls
The support roller is an important component in the steel rolling process. It is subjected to huge pressure and friction and is prone to wear and fatigue damage.
The use of laser cladding technology to repair and strengthen the support roller can form a high-strength, high-wear-resistant cladding layer on the surface of the support roller, thereby increasing the service life of the support roller.
The company uses laser cladding technology to repair its support rollers. The service life of the repaired support rollers has increased by more than 2 times, greatly reducing the company’s production costs.
Surface strengthening of work rolls
The working roll is the roll that directly contacts the rolled material, and its surface quality and performance have an important impact on the quality of rolled steel products.
By cladding a layer of high-performance alloy material on the surface of the working roll through laser cladding technology, the hardness, wear resistance and corrosion resistance of the working roll can be improved, and the surface quality of rolled steel products can be improved.
The rolling mill uses laser cladding technology to strengthen the surface of its working roll, which reduces the surface roughness of rolled steel products by more than 50%, and the product quality has been significantly improved.
Repair of special-shaped mill rolls
The shape of special-shaped rollers is complex, and traditional repair methods are difficult to ensure the quality of repair. Laser cladding technology can accurately clad the required materials on the surface of special-shaped rollers according to the shape and size of special-shaped rollers, thereby achieving high-quality repair of special-shaped rollers.
The steel mill uses laser cladding technology to repair its special-shaped rollers. The dimensional accuracy and surface quality of the repaired special-shaped rollers meet the production requirements, saving the company a lot of money and time.
