Advantages of cemented carbide rolls:
1. Excellent deformation resistance: High strength and creep resistance are maintained even during high-temperature (600-1000℃) rolling, making plastic deformation unlikely. The low coefficient of thermal expansion ensures stable roll ring dimensions during rolling, guaranteeing consistent product tolerances.
2. Corrosion and oxidation resistance: Strong resistance to corrosive media such as scale and coolants during the rolling process, reducing surface damage and slowing performance degradation in long-term or corrosive environments, suitable for complex operating conditions.
3. High thermal conductivity: Due to the high thermal conductivity of cemented carbide, cemented carbide rolls have good heat dissipation, shortening the time the roll surface is at high temperature. Therefore, the reaction time between the roll and harmful impurities in the high-temperature cooling water is short, so cemented carbide rolls have better corrosion resistance, cold fatigue resistance and heat fatigue resistance than tool steel rolls.
According to the structure, cemented carbide roll rings can be divided into integral cemented carbide roll rings and combined cemented carbide roll rings.
Integral cemented carbide rolls are widely used in pre-finishing and finishing stands of high-speed wire mills (including sizing and reducing stands and roll stands).
Combined cemented carbide rolls usually consist of a cemented carbide roll ring (working surface) and a steel matrix (support part), connected by interference fit, hot fitting or bolt fixing.
Combined cemented carbide roll rings are installed on the roll shaft, while combined cemented carbide rolls are formed by directly casting the cemented carbide roll ring onto the roll shaft to form an integral unit, used in rolling mills with larger rolling loads.
The tungsten carbide wire drawing dies produced by Zhuzhou Liling cemented carbide have good stability during wire drawing and occupy a large market share in the wire drawing die industry.
High hardness and good wear resistance: Room temperature hardness can reach HRA 78-93, good high-temperature red hardness, exceeding the room temperature hardness of high-speed steel at 600℃ and the room temperature hardness of carbon steel at 1000℃.
