Abstract
The invention relates to a graphite lubricant, in particular a process for lowering friction coefficient of graphite lubricant during seamless steel pipe rolling, wherein X light diffraction technique is employed to research the graphite crystal structure, and natural crystaline flake graphite crystal structure with small number of plies, high carbon content and large particle size is selected as the graphite for lubricant, anti-oxidant is also added to prevent graphite oxidization at high temperature, thus improving the lubricating property for graphite lubricant, and reducing the wear of core rods.
Description
technical field [0001] The invention relates to a graphite lubricant, in particular to a method for reducing the friction coefficient of the graphite lubricant in the rolling of seamless steel tubes. Background technique [0002] Graphite lubricants used in seamless steel pipe rolling (floating / boxing / clamping mandrel rolling technology), in which graphite is the main lubricating material, and the quality of graphite lubricating properties directly affects the quality of graphite lubricants. Quality, graphite lubricant has good lubricating performance (low friction coefficient), which can greatly reduce the wear of the mandrel and prolong the service life of the mandrel. Thereby greatly improving the quality of seamless steel pipe. In the prior art, graphite has not been carefully studied and selected. Therefore, the friction coefficient of the existing graphite lubricant is relatively high. SUMMARY OF THE INVENTION [0003] We have studied a method to reduce the fricti...
