In billet continuous casting production lines, the straightening machine bears the core responsibility of straightening and conveying the billet, yet it faces harsh operating conditions characterized by high temperatures, high loads, high dust levels, and corrosion from cooling water. Oil-air lubrication, with its precise adaptability, has become the preferred lubrication solution for straightening machines.
Firstly, it adapts to high-temperature, high-load conditions. Straightening machine bearings must withstand the heavy pressure of the billet and high-frequency friction. The gas-liquid two-phase film formed by oil-air lubrication can be 2-3 times thicker than that of traditional lubrication, increasing load-bearing capacity by 50% and effectively buffering mechanical shocks. Simultaneously, compressed air can quickly remove operating heat, reducing bearing temperature rise by 20-30°C and avoiding failure problems caused by grease carbonization in traditional lubrication.
Secondly, it provides powerful anti-contamination protection. In the straightening machine's working environment, scale and cooling water easily penetrate the bearings. Oil-air lubrication creates a positive pressure of 0.1-0.3 bar within the bearing housing, acting as a protective barrier to prevent impurities from entering, solving the problems of clogged lubrication pipes and component wear common in traditional lubrication systems. Actual measurements show that after adopting oil-air lubrication, the bearing life of the straightening machine increased from 60-90 days to 150-180 days.
Furthermore, it offers significant energy-saving and cost-reduction advantages. Oil-air lubrication, through precise oil supply control, drastically reduces lubricant consumption and avoids water pollution caused by dry oil overflow, thus reducing water treatment costs. Simultaneously, its comprehensive monitoring system can monitor lubrication status in real time, reducing downtime rates and enhancing production line efficiency.
The straightening machine is the core of the billet continuous casting production line, and its stable operation directly affects production efficiency and product quality. Oil-air lubrication is precisely adapted to its harsh operating conditions, effectively solving lubrication problems with its three core advantages: stable lubrication, strong anti-pollution, and energy-saving and cost-reduction. It not only extends the life of key components and reduces downtime rates but also helps companies reduce consumable and environmental costs.
