Optimize roll performance and extend lifespan with professional maintenance & repair services—reduce downtime, enhance durability, and ensure precision in metal rolling processes.
As the core component in metal rolling production, the maintenance and maintenance of mill rolls directly affect the operation efficiency and product quality of equipment. Scientific and standardized maintenance measures can effectively prolong the service life of mill rolls and reduce production costs.
In daily use, a periodic inspection mechanism should be established to focus on monitoring the wear of the mill roll surface, surface cracking and spalling. For local wear, precision grinding technology can be used to restore the mill roll accuracy; If deep cracks or large areas of spalling occur, they need to be reinforced by hardfacing welding, laser cladding and other processes, and ultrasonic flaw detection technology is used to assess internal damage.Lubrication management is the key to maintenance, and it is necessary to select high-temperature grease or water-based coolant according to the characteristics of the rolling material, and regularly clean the oil stain of the mill roll neck to avoid bearing jamming.
When the mill roll is out of service for a long time, it should be hung vertically in a constant temperature and dry environment, and the surface should be coated with anti-rust oil and wrapped with a protective film to prevent oxidation and corrosion.It is recommended to set up a professional maintenance team, formulate a personalized maintenance plan based on the equipment operation data, and achieve preventive maintenance through regular dynamic balance testing and roller surface hardness analysis.The standardized maintenance system can not only reduce unplanned downtime, but also improve the surface quality of rolled steel and create sustainable benefits for enterprises.
