Abstract

The invention discloses an antifriction, antiwear and antioxidation lubricant for metal hot rolling forming, a preparation method and application thereof. The preparation method of the anti-friction, anti-wear and anti-oxidation lubricant for metal hot-rolling comprises the following steps: adding a solvent to talc and a monovalent metal silicate to obtain a water-based suspension of talc; A dispersant is added to the turbid liquid and ultrasonically vibrated to obtain an anti-friction, anti-wear and anti-oxidation lubricant for metal hot rolling. The anti-friction, anti-wear and anti-oxidation lubricant for metal hot-rolled forming prepared by the method of the present invention is a water-based inorganic lubricant, which can be sprayed / coated on the surface of the metal material to be put into the furnace, and is especially suitable for silicon steel to prevent The occurrence of red iron sheet defects. The anti-friction, anti-wear and anti-oxidation lubricant prepared by the present invention forms a dense metal surface layer under high temperature conditions and has the functions of heat preservation, heat insulation and air isolation, and can protect the high temperature metal surface from oxidation.

Description

technical field [0001] The invention belongs to the technical field of metal surface oxidation resistance and workpiece / tool ​​contact interface anti-friction and anti-wear technology during metal thermoforming / processing (800-1000°C), and specifically relates to a metal hot-rolled forming anti-friction, anti-wear and anti-oxidation lubrication Agents and their preparation methods and applications. Background technique [0002] During the hot forming process of metal, severe friction and wear will occur at the working interface between the high-temperature metal and the processing tool, resulting in high energy consumption and excessive wear of the processing tool, and the metal surface will be severely oxidized under high temperature and unprotected conditions , It is easy to deteriorate the further wear of the tool surface and reduce the metal yield. Therefore, it is particularly important to introduce high-temperature lubricants suitable for metal hot forming conditions....
