There is a lubrication point on the roller table of the continuous casting machine of Hangzhou Iron and Steel Electric Furnace Company. The oil and gas lubrication system used is a combination of the single-line lubrication system and the working principle of oil and gas lubrication. The oil supply circuit adopts a single-line lubrication system with dual pump control, one for backup and one for use. The system mainly consists of a lubricating oil station, oil and gas distributor, various control components and pipelines.
Hangzhou Iron and Steel Electric Furnace Company changed the original dry oil lubrication method to
oil and gas lubrication. According to the comparison before and after the transformation, the bearing box with dry oil lubrication and the bearing with
oil and gas lubrication are better. There is a huge difference in appearance. The lubricating oil on the roller table using dry oil lubrication system can continue to be used, while the oil on the roller table using oil and gas lubrication can continue to be used. The bearing life is extended, which firstly saves a lot of maintenance time. Secondly, because the bearings are in good lubrication conditions, roller sticking and other situations are avoided to the greatest extent, so that the surface quality of the continuous casting billet has been improved to a certain extent. Thirdly, ordinary thin oil is used Replacing expensive high-temperature grease can save grease consumption by at least 10,000 yuan per month.
Through practice, the oil and gas lubrication system can well meet the lubrication needs of the equipment, can exponentially increase the service life of the bearings, and can greatly save the operating and maintenance costs of lubrication. Therefore, the oil and gas lubrication technology has extremely High promotion value.
