Why is oil-air lubrication more reliable under extremely low speed conditions?

In the extremely low-speed operation scenarios of industrial equipment such as slab and billet continuous casting machines, oil air lubrication is the superior solution.
The key lies in the gas-liquid two-phase film formed by oil-air lubrication. It is not a single liquid film, but rather possesses the dual functions of hydrodynamic and hydrostatic pressure. When equipment operates at extremely low speeds, the single-phase liquid film relied upon by traditional lubrication often fails to form a complete protective film due to insufficient speed, leading to direct contact between friction surfaces and impacting equipment lifespan.
But oil-air lubrication is different. Even at extremely low speeds, the gas-liquid two-phase film can still form stably and has a stronger load-bearing capacity. This special film keeps the relatively moving friction surfaces in a state of isolation and protection, avoiding wear, scratches, and other problems, ensuring that the equipment maintains good operating conditions even at extremely low speeds.
For heavy industrial equipment like slab and billet continuous casting machines that operate at extremely low speeds for extended periods, stable lubrication directly affects production efficiency and equipment maintenance costs. The unique advantages of oil-air lubrication in extremely low-speed scenarios have broken through traditional cognitive limitations and provided a more reliable option for the lubrication of industrial equipment.
