An Application Study on the Calcium Sulfonate Complex Greases in the Roll Neck Bearings of Hot Rolling Mills

摘要

1. The rolling mill's bearing are operated under harsh working conditions. 2. To achieve a high reliable operation, the bearing demands high performance grease in terms of Extreme Pressure and anti-wear properties, water resistance, corrosion resistance, and mechanical stability. 3. Field tests show that compared with a traditional bearing lithium complex grease, Calcium Sulfonate Complex Grease has obvious advantages. 4. When coming in contact with water, Calcium Sulfonate Complex grease keeps a good consistency, adhesion and anti-wear properties. 5. The grease consumption has been reduced. The calcium sulfonate complex evaluated has now become the grease of choice for hot rolling mill bearings.
