Ceramic rollers for steel line

Vesuvius' ceramic rollers, ZYAROCK, are used in continuous heat treatment facilities for steel strip such as silicon steel treatment lines, galvanizing furnaces and various types of annealing lines. This state-of-the-art product represents the ultimate solution in reaching high quality requirements on treated steel strips. The rollers are comprised of :

• A driven steel mandrel, made of stainless or heat treated alloy steel. It may be solid or hollow in order to permit water cooling.
• A Zyarock sleeve to assure the best possible contact with the heat treated strip.
• An attachment system comprised of a steel mandrel and Zyarokc sleeve insures outstanding reliability. Vesuvius' assembly method provides exceptional performance.

Vesuvius' Zyarock has unique material properties and is rigorously quality controlled at each step of the manufacturing process including machining. Therefore, Vesuvius offers a consistent high quality ceramic roller with superior surface finish and tight dimensional tolerances. Following are few of the proven benefits, which can be obtained from using Vesuvius' ceramic rollers:

• Strip surface quality improvements as Vesuvius rollers prevent oxides from sticking to the strip. The marking and downgrading effects on the finished products are avoided, thus reducing your operating costs
• Easy installation can be achieved with Vesuvius roller's exceptionally low thermal expansion characteristics (0.6 10-6/oC) that gives a very high thermal shock resistance. This also allows a quick installation without having to completely cool the furnace, which results in increased productivity for your operation.
• Increased resistance to deformation can be achieved with Vesuvius roller's high thermal stability for over long period of time.
