The billet continuous casting machine is the core equipment for solidifying and forming molten steel, and its lubrication system is crucial for its continuous and stable operation. Facing harsh conditions of high temperature, heavy load, and high dust levels, oil air lubrication, with its significant advantages, has become the preferred lubrication solution for 12 core components.

These 12 core components are: crystallizer, vibrating table, secondary cooling section, straightening machine, laying straightening machine, pre-cutting roll, post-cutting roll, conveyor roll, billet exit roller conveyor, turning machine, hot conveying roll, and cooling bed. From steel forming to finished product cooling and conveying, precise oil-air lubrication is essential.

Compared to traditional lubrication, oil-air lubrication offers significant advantages: precise and quantitative oil supply, forming a stable oil film, avoiding wear and oil waste; simultaneous cooling with compressed air, reducing bearing temperature rise by 20-30°C, resisting high-temperature corrosion; and positive pressure protection in the bearing housing, blocking dust and moisture, extending component life.

More importantly, oil-air lubrication boasts excellent environmental friendliness, consuming only 1/30th the amount of lubricating oil compared to dry oil lubrication, eliminating the risk of waste oil pollution, and perfectly aligning with the steel industry's green and low-carbon production philosophy. Simultaneously, it significantly reduces equipment downtime caused by lubrication failure, decreasing equipment maintenance workload and spare parts consumption. According to industrial measurement data from a steel plant, the annual comprehensive operating cost decreased by over 77% after implementing oil-air lubrication.

Scientifically selecting appropriate lubrication technology is crucial for ensuring the efficient and stable operation of billet continuous casting machines. Oil-air lubrication is comprehensively adaptable to all key components of the billet continuous casting machine from forming to conveying and cooling. Leveraging its core technological advantages, it effectively solves lubrication challenges under harsh operating conditions such as high temperature, heavy load, and high dust levels.
