Why Should Oil-Air Lubrication Systems Be Started Before Continuous Casting?

For continuous casting machines, stable lubrication during operation is critical to ensure smooth strand withdrawal and reliable equipment performance. Therefore, it is standard practice to start the oil-air lubrication system before casting begins.
Pre-starting the system allows lubricant to be delivered in advance, ensuring that all bearings receive equal and fresh lubrication from the very beginning of operation. This process helps form a stable and sufficiently strong oil film on the friction surfaces of the bearings before they are subjected to load.
By establishing this protective oil film early, the system effectively reduces friction and wear, preventing dry contact during startup—a critical phase when damage is most likely to occur. At the same time, continuous oil-air supply maintains the optimal lubrication condition, keeping bearings in a stable running state throughout the casting process.
This pre-lubrication strategy not only improves bearing performance and service life, but also reduces the risk of unexpected failures and downtime. As a result, oil-air lubrication systems play a key role in ensuring efficient, continuous, and safe operation of continuous casting equipment in the steel industry.
