Roll Grease
Product introduction:
Generally made with high-temperature resistant thickeners such as complex lithium, complex calcium sulfonate, polyurea, etc., combined with high-viscosity base oil and special additives including extreme pressure, anti-wear, water resistance and anti-oxidation agents. Roll grease is a special-purpose grease with high temperature resistance, extreme pressure performance, water resistance and long service life, specially developed for roll bearings, work rolls and backup rolls of steel, aluminum, copper and other non-ferrous metal rolling mills.
Performance characteristics:
Excellent high-temperature resistance, no melting, leakage or coking during long-term operation.
Extreme pressure and impact resistance with high oil film strength, preventing bearing raceway spalling, wear and seizure.
Excellent water resistance and demulsibility, good mechanical stability.
Superior rust and corrosion protection, long service life and low maintenance.
Application:
Suitable for heavy-duty metallurgical equipment under high load, high temperature, water exposure and high impact in iron and steel plants, metallurgical plants, hot rolling mills and cold rolling mills. Including full-process hot and cold rolling equipment in the metallurgical industry, such as hot continuous rolling mills, cold continuous rolling mills, rail beam mills, medium plate mills, pipe rolling mills, etc.
Operating temperature range: -20℃~220℃
