HP Rolmet N 34 is a premium non-staining rolling oil specifically developed for the cold rolling of copper and its alloys, including brass and German silver. Formulated from highly refined base oils, this product ensures excellent oxidation stability, superior lubricity, and minimal residue formation on rolled surfaces. Its carefully balanced composition provides superior non-staining performance, making it particularly effective for processes where the brightness and finish of the metal surface are critical. This rolling oil is ideal for use in multi-roller mills such as SENZOIMER and SUNOWIG, where it serves both as a rolling lubricant and a bearing oil. It ensures excellent film strength, reducing metal-to-metal contact between rolls and strips, thereby minimizing wear and extending roll life. The low staining property of HP Rolmet N 34 enhances the surface quality of rolled products, delivering a clean, polished appearance suitable for further finishing operations such as electroplating and annealing. In addition to copper and its alloys, HP Rolmet N 34 can also be effectively used for rolling carbon steel and stainless steel strips. Its superior cooling and lubricating properties enable efficient heat dissipation during rolling, ensuring dimensional accuracy and improved mill performance. The product’s excellent oxidation resistance prevents gum and sludge formation, keeping the system clean and reducing maintenance downtime. With a kinematic viscosity of 10 cSt at 40°C and a flash point of 140°C, HP Rolmet N 34 offers an optimal balance of cooling and lubricating performance. Designed to meet the rigorous demands of precision rolling operations, it provides consistent quality, extended roll life, and improved surface finish, making it the preferred choice for non-ferrous and steel rolling applications.
