Laser quenching of large roll is an advanced surface treatment technology that uses high energy laser beam to rapidly heat and cool the surface of large roll to achieve surface hardening and strengthening. The technology has the advantages of fast processing speed, precise control of hardening layer depth, and strong adaptability to roll shape and size. Therefore, laser quenching is widely used in the field of roll manufacturing and repair in steel, non-ferrous metals, rubber and other industries.
The principle of large roll laser hardening technology is to use a high-energy laser beam to quickly scan the surface of the roll, so that the surface material of the roll is heated to a melting or boiling state in a very short time, and then quickly cooled to achieve surface hardening and strengthening. In this process, the energy density of the laser beam, scanning speed, spot size and other parameters have an important effect on the depth of the hardened layer, hardness, wear resistance and other properties.
The advantages of large roller laser quenching technology mainly include the following aspects
1. It can achieve rapid heating and cooling, thus greatly shortening the processing time, improving production efficiency.
2. It can accurately control the hardening layer depth, hardness and other performance indicators to meet different working conditions and process requirements.
3. It is a roller with strong adaptability to the shape and size of the roller and can handle various complex shapes and sizes.
4. Laser quenching technology is a non-contact process, which will not cause mechanical damage or deformation of the roller.
5. Laser quenching technology has better environmental performance and produce less waste and pollution.
In the steel industry, large roll laser hardening technology is mainly used for the manufacture and repair of rolls. Through laser quenching technology, the hardness and wear resistance of the roll can be significantly improved, thus extending the service life of the roll and reducing the production cost. In addition, large roll laser hardening technology is also widely used in the field of roll manufacturing and repair in non-ferrous metals, rubber and other industries.
In short, large roller laser quenching technology is an advanced surface treatment technology, with many advantages and application prospects. With the continuous development and improvement of technology, it is believed that laser quenching technology will play a more important role in the future manufacturing field.
