Problems solved by technology

[0010] Although the above technologies can prepare oil film bearing oil that meets the requirements, due to the harsh working conditions of high-speed wire rod mills, especially the presence of a large amount of cooling water in the working environment, the lubricating oil prepared by the existing technology cannot quickly and completely separate water. In addition, the compatibility between the demulsifier and the lubricating oil is not good, and it is easy to separate from the oil, so it cannot meet the normal working requirements of the high-speed wire rod rolling mill.

Abstract

The invention provides a bearing oil composition and a method for improving the performance of the bearing oil. The bearing oil composition of the present invention comprises: alkylthiophosphonic acid anhydride, demulsifier, extreme pressure antiwear agent, antioxidant, oiliness agent and main amount of lubricating base oil. The bearing oil composition of the present invention has excellent anti-wear and extreme pressure properties, anti-oxidation properties, anti-foaming properties, anti-corrosion and anti-rust properties, anti-emulsification properties, fast and thorough water separation, and can ensure high-speed wire rod rolling mills in a large amount of water Normal operation when present, suitable for lubrication of oil film bearings in high-speed wire rod finishing mills.

Description

technical field [0001] The invention relates to a bearing oil composition, in particular to a bearing oil composition suitable for bearings of high-speed wire finishing mills. Background technique [0002] With the development of the metallurgical industry, high-speed rolling mills for steel plates and bars have developed rapidly. At present, dozens of high-speed wire rolling mills have been introduced in my country, making great contributions to the development of the national economy. [0003] The high-speed wire rod mill has complex mechanical transmission, compact structure, high precision and fast speed. The high-speed wire rod mill operates at a speed of up to 120m / s, which makes the oil film bearing withstand high-speed and large-torque loads. Therefore, it is necessary to use special lubricating oil for lubrication. In addition to meeting the oil lubricity requirements of oil film bearings, it is also necessary to consider the extreme pressure requirements of gear tr...
