Ⅰ. Technical Introduction
With the development of the steel industry, the rollers are seriously damaged due to strong pressure and wear, causing huge economic losses to the company. In response to this problem, HUIRUI-LASER laser cladding ring rolling machine roller repair technology came into being. This technology uses methods such as laser cladding and rolling correction to repair roller damage in an efficient, reliable and economical way.

Ⅱ. Technical Principle
1. Laser Cladding
Laser cladding is to melt the damaged part of the roller with a high-energy laser beam, and then reconstruct it to achieve the effect of repairing the damaged part of the roller. Laser cladding can not only eliminate surface cracks, but also fill the wear in local areas and restore the roller to its original working state.
2. Rolling Correction
Rolling correction is to repair the roller through rolling and correction force to achieve the purpose of restoring the roundness and normal state of the roller working surface. After roller straightening, the high consistency of the roller working surface can be guaranteed, and production efficiency and economic benefits can be improved.

Ⅲ. Technical Application
HUIRUI-LASER laser cladding ring rolling machine roll repair technology has been widely used in the steel, aluminum and other industries, and has become the preferred method for enterprise roll repair. This technology can not only repair the damaged parts of the roll, improve production efficiency and economic benefits, but also reduce the production costs of the enterprise. In addition, this technology is also environmentally friendly and energy-saving.

Ⅳ. Conclusion
With the continuous development of the steel industry, roll repair technology is also constantly improving. HUIRUI-LASER laser cladding ring rolling machine roll repair technology uses laser cladding and rolling correction to make the roll look brand new, and has become the focus of attention in the steel industry. The application of this technology can not only improve the production efficiency and economic benefits of the enterprise, but also reduce the losses caused by roll damage to the enterprise. It is a necessary technology for the enterprise.
