When it comes to lubrication under ultra-low speed conditions, many still instinctively rely on traditional methods. However, in real industrial applications—such as slab and billet continuous casting machines—oil-air lubrication proves to be the superior solution.

The key lies in the unique air-oil two-phase lubrication film formed by oil-air systems. Unlike conventional lubrication, which depends on a single-phase liquid film, oil-air lubrication combines the advantages of both hydrodynamic and hydrostatic lubrication effects.

In ultra-low speed operations, traditional liquid lubrication often struggles because insufficient speed prevents the formation of a stable oil film. As a result, metal surfaces may come into direct contact, leading to increased friction, wear, and reduced equipment life.

Oil-air lubrication, however, performs differently. Even at extremely low speeds, the two-phase oil-air film can still form and remain stable, providing a stronger load-carrying capacity. This protective film effectively separates friction surfaces, ensuring that they remain in an optimal working condition at all times. As a result, issues such as wear, scoring, and surface damage are significantly reduced.

For heavy-duty industrial equipment like continuous casting machines, which operate under low speed, high load, and harsh environmental conditions, reliable lubrication is directly linked to production efficiency and maintenance costs. Oil-air lubrication not only ensures stable performance but also extends bearing life and reduces downtime.

By overcoming the limitations of traditional lubrication methods, oil-air technology offers a more advanced and dependable solution for extreme operating conditions, making it the preferred choice for modern industrial lubrication systems.
