Tungsten Carbide Rolls
Tungsten carbide rolls, also known as cemented carbide composite roll is mainly used on the finishing mill for bar, deformed steel bar and common wire.
In this way, we can greatly reduce the frequency of changing groove and roll, thus to reduce the labor intensity and improve the work efficiency. The surface quality and yield shall be improved to a maximum degree, which leads to a remarkable economic benefit.
Our cemented carbide composite roll adopts a special grade of cemented carbide. By means of hydraulic lock nut, the cemented carbide roll rings is fastened to the axle with the axial pressure of 200Mpa from hydraulic oil. Under the protection of pressure, the cemented carbide composite roll shall work more effectively.
In accordance with the production line and rolling technology of customers, our products are designed to match one-strand rolling, twoslitting rolling and three-slitting rolling and four-slitting rolling, the cemented carbide composite roll includes K1 finished roller, K2 lederroller, K4 pre- slitting roller. K3 slitting roller with high-speed steel as material. The rolling varieties include wire, bar and deformed steel bar.We can effectively reduce the frequency of changing rollers and increase the yield after using cemented carbide composite roll. The rolling products possess the features of good surface quality, small deformation, negative tolerance and high yield.
Advantages Of Using Tungsten Carbide Rolls
• reduce mill downtime, high rolling speed, increase productivity
• made from virgin raw materials, a wide range of grade applications, HIP sintering good surface finish for rolled product
• good wear resistance, high strength and toughness, excellent hardness and heat fatigue resistance
• Non-destructive ultrasonic flaw detection, without sand hole, pore, cracks and inclusions
Tungsten carbide rolls are widely used in the production of wire rods, rebars and seamless steel pipes due to their good properties, which greatly improve the working efficiency of the rolling mill. According to the different working conditions of different stands and rolls, a variety of different grades of cemented carbide rolls have been developed.
