Ceramic guide rolls offer up to 10 times the life of steel rolls, due to the excellent abrasion resistance of Si3N4. This results in less down time and a product with a higher quality surface finish. As with conventional rolls, the profiles can be reground. Due to their very light weight, the rolls accelerate and decelerate faster than conventional rolls, thereby reducing scuffing and so called brake marks. Ceramic rolls are particularly suitable for the production of wires used in the construction industry.
