Special linings for rollers

Ceramic Fiber Discs

Sifra International produces special coatings for rollers including ceramic fiber discs, or discs produced with a special ceramic material combined with mineral fibers. These discs must be mounted on cooled rollers for annealing furnaces for austenitization of the cold-rolled steel at high temperatures.

Pressed sleeves

Sifra International also realizes pressed sleeves consisting of discs made with fiber-textile materials, compressed and glued between them. The sleeves are polymerized and together they orm an extremely compact monoblock. They are a valid and effective alternative to rubber and polyurethane: the sleeves are used in cases in which the roller needs frequent spare parts owing to wear. Sifra International manufactures various types of pressed sleeves: for a correct choice, you need accurate information about employment conditions.
