Hyperion Talus Hot Rolling Clamping

Cast-in-Carbide (CIC®) Rolls

Cast-in-carbide (CIC®) rolls from Hyperion Materials & Technologies are the ultimate in durability and performance for rolling mills. Made with a tungsten carbide layer bonded to a cast iron ring, these rolls are incredibly hard and wear-resistant, making them ideal for high-volume production. CIC® rolls also have excellent thermal conductivity, which helps to dissipate heat and prevent the rolls from overheating. As a result, CIC® rolls from Hyperion offer a longer service life, lower maintenance costs, and improved product quality.

In addition to their durability and performance, CIC® rolls are also very versatile. Hyperion can help design CIC® rolls in a variety of sizes and shapes to meet the specific needs of your rolling mill.

 

CIC® Integral

CIC® Integral rolls are optimized for the early and intermediate stands in the rolling mill. CIC® Integral rolls best suited for the highest rolling torque and force and low rolling speeds, even below 1 m/sec. The cast iron arbor and the cemented tungsten carbide rings are cast and machined in one solid piece, with no keys, no keyways, and no locking nut. This allows higher torque transmission than that of conventional combi rolls. The absence of a locking device also allows for more passforms for productive hot rolling.

 

CIC® Combi

The CIC® Combi roll by Hyperion consists of CIC® rings secured to a cast iron or steel arbor with locking nuts, keys, drive pins, bolts, and spacers. Because the CIC® rings are exchangeable, CIC® Combi Rolls allow for a versatile range of design options that can be tailored to each application.

 

Talus™ Rolls

Talus™ system rolls are composite rolls assembled with tungsten carbide rings that can use either a mechanical or hydraulic clamping system. The Talus™ system expands our complete set of composite rolls solutions, allowing us the flexibility to offer a tailor-made roll for any rolling mill application.

FAQs about Carbide Rolls

What are the applications for tungsten carbide rolls?

Tungsten carbide rolls can be used in the intermediate finishing sections of rolling mills.

What is the maximum roll size that can be produced in tungsten carbide?

Hyperion can produce tungsten carbide rolls with outer diameters of up to 550 millimeters.

What changes do I need to make in the rolling mill to convert from cast iron or steel rolls to tungsten carbide rolls ?

To convert from cast iron or steel rolls to tungsten carbide rolls, Hyperion carbide rolls product speciailists will partner with rolling mills to revise roll cooling, machining, and handling capabilities. Most rolling mills can easily adapt from cast iron to tungsten carbide.

What is the expected difference in durability and roll life between Hyperion tungsten carbide rolls and other solutions?

Hyperion tungsten carbide rolls have a longer lifespan of up to 20 times longer than that of cast iron rolls due to their higher wear resistance. This results in reduced stoppage time for the rolling mill along with higher productivity and lower operational costs

What is the minimum rolling speed at which tungsten carbide rolls can be used?

The minimum rolling speed tungsten carbide rolls can be used at is one meter-per-second (1 m/s).

What are the cooling recommendations for using tungsten carbide rolls?

Proper cooling is crucial to ensure optimal performance of carbide rolls. The minimum recommended pressure is 4-to-6 bar and 250-to-300 liters per minute per passform.
