Heavy-duty antiemulsifying oil film bearing oil

Abstract

A heavy-duty antiemulsifying oil film type bearing oil for high-speed wire rolling mill contains demulsifier, antiwear agent, antifoaming agent, alkylnaphthalene, antioxidant and mineral oil. Its advantages are excellent antiemulsifying, antiwear, anti-extreme-pressure, anticorrosion, antirust, antifoaming and antioxidizing performance, and better viscosity-temp characteristic.

Description

technical field [0001] The invention relates to an industrial oil product, in particular to a heavy-duty anti-emulsification oil film bearing oil used in high-speed wire rod finishing mills in the metallurgical industry. Background technique [0002] The oil film bearing is a sliding bearing with mineral oil as the lubricating medium and the principle of hydrodynamic lubrication as the mechanism. It relies on the power of the rotating shaft to bring the oil into the wedge-shaped gap to form a pressure oil film, balance the load, isolate the journal and the sleeve, and separate the metal The friction between solids is converted into molecular friction (viscosity) inside the liquid, which reduces friction and wear to a minimum, so it can meet the bearing pressure, impact resistance, speed range, rolling accuracy, structural size and service life in the maximum range. [0003] In the metallurgical system, due to the continuous development of requirements, the working conditions...
