A metal high-temperature protective lubricating coating and its preparation method, usage and recycling method. The metal high-temperature protective lubricating coating includes components and mass percentages of 0-90% oxide powder A, 0-90% oxide powder B, 0.2-50% solid particle additive, 1-50% solvent and 0% ‑5% surfactant, and provides its preparation method, and its use method through protection, heating and thermal processing (rolling, forging or extrusion, etc.), and its recovery and reuse method. The metal high-temperature protective lubricating coating has low cost, simple process, environmental protection and pollution-free, easy to recycle, and can be reused. It can realize green environmental protection in the large temperature range from room temperature to 1450°C to prevent metal from being oxidized and nitrided. Can play a role in lubrication during thermal processing. |
