Problems solved by technology

However, these protective lubricants used are generally easy to corrode the metal blank during the heating process, and form new substances to cause further damage to the metal forming surface and the mold surface, for example, silicic acid commonly used in these protective lubricants Salt glass and borate glass raw materials cause serious corrosion to metals due to their strong alkalinity, and the eroded parts are extremely difficult to clean
Especially under high temperature conditions such as 1000°C, the corrosion phenomenon of existing protective lubricants is more serious

Abstract

The invention relates to a metal protection lubricant for preventing metals from being damaged when being machined and forged as well as a preparation method and an application of the metal protection lubricant. The metal protection lubricant comprises the following raw material components: lead glass, cordierite, Gr2O3, clay, methylcellulose and water. The metal protection lubricant not only isolates the external atmosphere to protect metal profile matrixes, but also functions as a good lubricant which has the abrasion reduction function in thermal deformation machining, the metal protection time is greatly prolonged, metal erosion is prevented, and moreover the metal protection lubricant can automatically drop off after being forged, so that later treatment procedures caused by coating are canceled, the protection of the properties of metals is sufficiently achieved, the forging quality is effectively improved, the surface effect in metal forming is optimized, and the quality of a product is improved, and the service life of a product, such as a die, which is forged in such a mode is prolonged, and therefore, the metal protection lubricant is applicable to popularization and application in relevant fields.

Description

technical field [0001] The invention relates to a metal protective lubricant, a preparation method and an application thereof, in particular to a metal protective lubricant for protecting metal processing and forging from damage, a preparation method and an application thereof. Background technique [0002] At present, in the field of metal profile processing such as alloy steel, since the profiles contain S, P, C and other substances to varying degrees, if these trace substances are oxidized, they will directly affect the performance of the metal profiles, for example, aerospace parts The main components of special abrasive steel are C, Cr, Mo and AI alloy structural steel. During the high temperature forging process, the S, P, C precipitation and metal oxidation in its structure have great effects on the metal performance and forming effect, as well as the service life of the mold. Therefore, it is necessary to take effective protective measures for the processing and forg...
