mandrel graphite lubrication system

The mandrel lubrication system is a crucial piece of equipment in a seamless steel pipe continuous rolling mill. Its function is to atomize graphite lubricant and spray it onto the mandrel, forming a dense, uniform, and dry graphite lubricant layer on the mandrel surface. The purpose of mandrel lubrication is to reduce the coefficient of friction between the mandrel and the inner surface of the steel pipe, thereby improving the inner wall quality of the steel pipe, extending the service life of the mandrel, reducing rolling force and power consumption, reducing or preventing mill jamming accidents, and creating conditions for smooth pipe removal. Specific applications: Mandrel lubrication in steel pipe rolling can be designed according to different mill units.

System efficacy:

a. Applying lubricant to the mandrel surface to improve lubrication.

b. Improved surface lubrication can reduce mill load.

c. Improved surface lubrication significantly increases the lifespan of the mandrel.

d. Improved product surface quality and reduced scrap rate.
