Te production process in steel mills is pretty long with numerous equipment exposed to a variety of working conditions that require diferent greases. For example, some equipment exposed to large amounts of water for extended periods of time require grease with excellent water resistance properties. In the areas of high ambient temperature and long re-lubricating intervals, the grease requires thermal and oxidative stability. In alkaline environments, the grease needs excellent protective properties. Calcium sulfonate complex grease (CSCG), with its comprehensive and excellent properties, is increasingly popular in the steel mill industry. Certain properties of CSCG can be further improved by formulation?and process design to meet requirements of grease on diferent equipment in steel industries. Typical data for several CSCGs will be presented in this paper. In addition, their application performance in the equipment in wet, rusty, high temperature, alkaline environments and open gears will also be discussed.
