Description

technical field [0001] The invention relates to the field of high-temperature lubrication, in particular to a coated graphite protective lubricant, a preparation method and a use method thereof. Background technique [0002] Forging is a system engineering involving many links, and forging technology is the basic technology supporting modern industry. Can be divided into cold forging, hot forging, warm forging, sub-hot forging, closed forging, ring rolling forging. The most important and critical link in the forging process is the mold. Forging dies usually have to withstand high pressure at a high temperature of hundreds of degrees or even thousands of degrees to complete metal forming. Fierce market competition forces customers to put forward higher requirements for forgings. Therefore, improving the quality of forgings, reducing the cost of forgings, and prolonging the life of the die are forging key to business survival. [0003] Undoubtedly, improving the life of the...
