An optimized combination of cemented carbide and ductile iron, Hyperion Materials & Technologies' cast-in-carbide (CIC®) combi rolls merge excellent pass form wear resistance with strength and toughness in the roll body.
Containing an optimized combination of cemented carbide and ductile iron, CIC combi rolls merge excellent pass form wear resistance with high strength and toughness in the roll body. The composite design of CIC combi rolls means that carbide performs the rolling, while torque transmission is handled by the ductile cast iron.
CIC combi rolls improve productivity because of two distinct advantages:
Hyperion's CIC combi roll concept consists of four elements: the CIC ring, the arbor, the drive keys, and the locking nut. For reliable torque transmission, keyways are machined into the CIC ring's iron body. The cast iron arbor and the cemented carbide rings are cast and machined as one solid piece.
Hyperion's CIC integral rolls provide the strongest design available for the early and intermediate stands in your mill. The are 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 carbide rings are cast and machined in one solid piece, with no keys, no keyways, and no locking nut. This permits torque transmission higher than that of conventional CIC combi roll. Also, because there are no locking devise that take up space, more pass forms are available for productive rolling.
Hyperion CIC tube rolls can give a pass life up to 40 times that of conventional iron rolls. CIC tube rolls provide excellent surface finishes, tolerances, and geometries of the rolled tube.
Hyperion's CIC cantilever rolls are often used in the intermediate and finishing sections of rod mils. Compared to the alternative, a carbide ring on a separate steel body, CIC rolls are easier to mount and require less machining of roll parts. CIC rolls guarantee the absence of carbide ring slippage.
Hyperion's product specialists are available to help you determine the best solution for all of your hot rolling needs.
