Abstract

The invention discloses a low-alloy steel hot-forging lubricant composition. #680 cylinder oil used as base oil is matched with multiple composite additives, including an antioxidant, an anti-wear agent, an oily agent, a metal deactivator, a friction modifier, a corrosion inhibitor and a reinforcing agent. The lubricant composition disclosed by the invention is relatively low in viscosity, large in heat capacity, high in cooling and washing property, good in lubrication property and extreme pressure property, stable in component and property, free of corrosion to metal and equipment and free of toxicity or pungent smell, and the phenomenon that a forge piece is adhered to a mold is reduced.

Description

technical field [0001] The invention belongs to the field of lubricants, in particular to a low alloy steel hot forging lubricant composition. Background technique [0002] Forging can be divided into various processing methods such as free forging, high-speed forging, roll forging and precision die forging according to the processing method; it can be divided into cold forging, warm forging and hot forging according to the temperature conditions of the forming process of the material. The purpose of forging is mainly to improve the uneven distribution of alloy compounds in the billet, thereby improving the mechanical properties of forgings. Forging is defined as the process of compressing or upsetting in an open die and forming a blank in a closed die to discharge excess metal into a burr slot. It should be noted that the forging process can be carried out under the condition of impact (hammer forging), or under the condition of slow speed (press forging), and the processi...
