Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a self-lubricating sliding bearing seat, in particular to a self-lubricating sliding bearing seat for a free roll of a continuous casting machine. Background Art
[0002] On the production line of a steel mill, the continuous casting machine is a production equipment that can continuously cast high-temperature molten steel into ingots with a certain cross-sectional shape and certain size specifications. It reduces the multiple steps in the traditional mold casting process, can achieve continuous and uninterrupted production, greatly improves the efficiency of steel production, and saves the consumption of production tools such as ingot molds, thereby reducing production costs.
[0003] During the continuous casting process, the billet is in a high-temperature softened state and has a large weight. The free roller on the continuous casting machine can support the billet to prevent it from sagging and deforming due to gravity, ensuring that the billet moves forward smoothly in the predetermined direction and avoiding the billet from running off track. The rotation of the free roller can reduce the friction of the billet during operation, reduce energy consumption, and also reduce the wear and scratches on the billet surface. Under high temperature and continuous working conditions, the operation of the free roller mainly relies on the self-lubricating sliding bearing seat that supports it to complete the work.
[0004] The existing self-lubricating sliding base adopts special materials and structural design, which can achieve self-lubrication to a certain extent and reduce the number of times lubricants are added manually. However, when the self-lubricating bearing base used on the free roller of the continuous casting machine faces high temperature and continuous operation, the solid lubricant of the self-lubricating bearing base is unevenly distributed, affecting the quality of the lubricating film formed on the friction surface, making it difficult to achieve the desired effect, and also accelerating the wear of the bearing itself.
