HP Rolmet 7 is a premium-quality neat cold rolling oil formulated for the cold rolling of stainless steel where an exceptionally smooth and bright BA (Bright Annealed) finish is required. It delivers a highly polished surface texture with minimal surface defects, ensuring a spotless and uniform finish. Manufactured from highly refined, low-viscosity base oils, HP Rolmet 7 is blended with ultra-low sulfur and aromatic content additives that offer superior lubrication, rust protection, and anti-staining performance. Its advanced additive system ensures a high viscosity index, providing stability across a wide range of temperatures and operating conditions. HP Rolmet 7 effectively reduces the coefficient of friction between the roll bites, optimizing rolling speed and reduction percentage based on the type of metal surface, roll diameter, and process parameters. This results in improved productivity, enhanced finish quality, and extended roll life in precision stainless steel rolling operations. The oil demonstrates excellent thermal stability, ensuring consistent performance and protection of rolls and bearings from heat-related wear. Its unique formulation provides clean rolling surfaces, minimizes oil consumption, and contributes to longer oil service life. Additionally, HP Rolmet 7 is biodegradable, making it a more environmentally responsible choice for metalworking operations. Widely trusted in industrial applications, HP Rolmet 7 is successfully used by one of India’s largest stainless steel manufacturers, M/s Jindal Steel (JSL), for the production of razor blade strips and coin blanks. With its superior lubricity, cleanliness, and cooling efficiency, HP Rolmet 7 stands out as the ideal cold rolling oil for high-speed, high-precision stainless steel rolling operations demanding a brilliant, defect-free finish.
