Carbon steel warm-forging lubricant composition

Abstract

The invention discloses a carbon steel warm-forging lubricant composition which adopts No.680 cylinder oil as basic oil and is matched with multiple composite additives which include an antioxidant, an antiwear additive, an oiliness agent, a metal passivator, a friction improver, a reinforcing agent, a corrosion inhibitor and a preservative agent. The carbon steel warm-forging lubricant composition disclosed by the invention is preferable in flowability and high in diffusion capacity, is capable of forming a layer of uniform and continuous oil film between a forge piece and a mould, has the advantages of good antiwear property and viscosity-temperature property, high extreme pressure property, stability in oil film thickness, good pressure-resistant property, good lubricating property, stability in component, no toxicity and no pungent smell and can be used for protecting a material from being cracked in a forging process, preventing the mould from being damaged and prolonging the service life of the mould.

Description

technical field [0001] The invention belongs to the field of oil lubricants for metal processing, in particular to a carbon steel warm forging lubricant composition. Background technique [0002] Carbon steel mainly refers to an iron-carbon alloy with a carbon mass fraction less than 2.11%, sometimes also called plain carbon steel or carbon steel. This unique variety of steel has considerable advantages over other types of metals in its usage and function, being used for masonry nails and cutting tools due to its enormous strength and durability. Steel has a high carbon content, has a huge hardness level, and is resistant to wear, so in metal cutting tools and other machinery in many manufacturing industries, carbon steel is also used to make drills, knives, wood cutting tools, saws and metal cutting tool. [0003] Iron and steel materials have the characteristics of relatively abundant resources, large production scale, easy processing and manufacturing, diverse and relia...

Problems solved by technology

Generally, the recrystallization temperature of steel is about 750°C. When forging above 700°C, the deformation energy can be dynamically released, and the forming resistance decreases sharply; The carbon phenomenon is relatively slight, and the size of the forging changes little; when forging above 950 ° C, although the forming force is smaller, the scale and surface decarburization of the forging are serious, and the size of the forging changes greatly
