Rotor Gunning Machine: Applications and Scenarios
The rotor gunning machine is mainly used for the rapid repair of industrial equipment and material spraying. It uniformly adheres wear-resistant and high-temperature-resistant materials to the equipment surface through a spraying method, thereby extending the equipment's service life. The specific application scenarios are as follows:
Coke Oven Wall Repair
It is suitable for the rapid repair of coke oven carbonization chambers, riser pipes, regenerators and other parts. Adopting semi-dry gunning technology, only 12%-15% water needs to be added to form a slurry with strong adhesion, and it can repair approximately 2 square meters of damaged areas per hour.
Mining and Tunnel Engineering
Rotor-type concrete gunning machines are widely used in mine support and tunnel construction. They uniformly spray concrete onto the wall surface through high pressure to quickly construct support structures.
Industrial Equipment Maintenance
It is applied to the surface repair of components such as rolling mill rotors. Laser cladding technology is used to improve wear resistance. A case study shows that the surface hardness after repair can reach HRC 58-62, and the service life is increased by more than 30% compared with new products.
