Carbide Mill Rolls for Hot Rolling Mill will improve product quality, reduce downtime, and increase productivity to bring a better production economy. Tungsten carbide mills rolls are mainly used in Wire Rod Rolling mill, steel rebar Rolling Mill. UKO TC rollers can be used in High Speed Rolling Mills, Wire Rod Rolling Mill, TMT Rolling Mill, Rebar Rolling Mill, Wire Rod Rolling Mill.
The cemented carbides rolls are divided into the conventional WC-Co alloys and the corrosion resistant alloys with a mixed binder Co-Ni-Cr. The binder contents vary according to the specific requirements of the rolling mill. We also offer composite roll rings that are a combination of cemented carbide and steel. Unlike the relatively brittle cemented carbide rings, these composite rings open up a wide range of applications. These roll rings can be shrunk on the shaft without any clearance between the shaft and the ring, leading to an increased stiffness of the roll shaft and a higher rigidity of the system. For the transmission of higher torques, keyways can be machined in the faces or in the inner diameter of these roll rings. These rings are used in the intermediate stands and blocks with a 3-ring layout as well as stretch reducing tube mills.
For intermediate stands of bar and wire rod mills, and finishing stands of bar mills, we have combirolls. This consists of a composite roll ring with a mechanical clamping system, providing a high wear resistant layout that allows for the utilisation of the full width of the roll table. Combirolls are provided with a maintenance free clamping system that does not need to be retightened. Additionally, the roll shaft can be equipped different times with new roll rings.

Carbide roll rings with grooves
During rolling micro-cracks and wear in roller’s grooves is usual in daily production, and grooves need to be reground when cracks are at depth around 0.2mm. Excess rolling causes the depth of micro cracks to extend rapidly and will increase the dangers of crushing rolls, which can be avoided by reground timely.
Note: We can supply according to the drawings provided by customers, that determined based on customers’ requests.
According to customers’ mills and production lines, we offer a unique rolling design for single-rolling, two-slit, three-slit and four-slit stands. The composite rolls can be used as K1 finished roll, K2 leader roll, K3 slitting roll and K4 pre-slitting roll for the rolling of wire rod, bar and rebar.
Benefit
- High Durability: These rolls are made from a combination of tungsten carbide and cobalt, which gives them the ability to withstand high temperatures and pressures. This durability can lead to reduced maintenance costs and improved efficiency.
- High Precision: These cemented carbide mill rolls can be manufactured to very tight tolerances, which means that the rolls can produce consistent results, leading to better quality products.
- Improved Productivity: Due to the longer lifespan and less frequent replacement needed, tungsten carbide rolls can help reduce production costs over time, making them a cost-effective option for many industries.
