China's steel output is huge, and steel mills also have a huge demand for grease. However, the working conditions of steel mills pose great challenges to the performance of grease: high temperature, high water content, heavy load, etc. Once the lubrication fails, the grease in the bearing may turn black, coke and carbonize, causing the bearing to run difficultly, aggravated wear, and serious burning of the bearing. Such losses will be a huge economic loss for steel mills with very large output. Therefore, choosing the right grease is very critical.

Requirements for the selection of grease for steel mills:
1. Extremely strong oil film lubrication strength: Most metallurgical equipment is subjected to heavy load impact or vibration during work, which is not conducive to the establishment and maintenance of the oil film in its lubricated parts;
2. Extremely strong protective performance: The equipment is in harsh working conditions for a long time, such as large dust, many waste oil impurities, more water cooling media, more corrosive gases, etc., which are easy to corrode the surface and lubrication parts of the equipment, causing the working medium of the equipment to deteriorate easily and accelerate the wear of the equipment Damage;
3. Excellent water resistance: Due to the high operating temperature of the equipment, the lubrication parts and equipment surface are often directly cooled by the water cooling system, which is easy to cause the emulsification and deterioration of the lubricating material, and the oil-water separation performance of the working medium is required to be excellent;
4. Excellent pumping performance: Due to the large structure of the equipment, it has many lubrication points, and it is difficult to inject grease manually. A centralized automatic lubrication system is often used;
5. Outstanding anti-pollution performance: Most equipment transmission systems are relatively simple, and there are many open transmission systems, and the anti-pollution ability and extreme pressure resistance of lubricating materials are required to be high.
Therefore, heavy-duty grease with extremely high load capacity at high temperature, excellent waterproofness, super anti-corrosion protection and excellent performance is suitable for use in steel plants. It does not contain heavy metals and ingredients that are not good for the environment. This high-efficiency grease has a long life and extreme pressure characteristics at high temperatures, which can effectively extend the bearing life of steel plant production equipment.
