Tungsten Carbide Guide Roller

Product Description

What is a guide roller?

In mechanical transmission systems, people use guide rollers to change the direction of transmission movement and ensure its smooth operation. They are usually composed of spacers, guide roller shafts, guide rollers, glands, and bearings. Guide rollers play an important role in working environments such as mining equipment and construction machinery.

So in general, guide rollers can guide, adjust and support moving parts to ensure that moving parts run along a predetermined trajectory, reduce friction, vibration and offset, and may also assume tension adjustment or support functions.

Types of guide rollers (classified by material)

1. Metal guide rollers
2. Nylon/plastic guide rollers
3. Ceramic guide rollers
4. Composite guide rollers

Application and advantages of Tungsten Carbide Guide Rollers

Like other carbide parts, carbide guide rollers have ultra-high hardness, wear resistance and corrosion resistance. Made of tungsten carbide, it is sintered and polished through powder metallurgy. Its hardness is 3~4 times that of ordinary steel, and its service life is 5-10 times that of steel guide rollers. Therefore, the main purpose of using cemented carbide to make similar parts is to reduce the frequency of downtime and replacement. Therefore, the maintenance cost is low. In general, the overall cost is lower than that of ordinary metal guide rollers.

In the process of using WEDM-HS, Low Speed Wire Cut and other machine tools, the accuracy of the electrode wire path is very important. For example, in WEDM-HS equipment, the electrode wire moves repeatedly at high speed, which causes great friction loss to the guide roller. In order to withstand such high-frequency friction and vibration, the excellent physical properties of cemented carbide make it a leader in this field. For Low Speed Wire Cut equipment, although the operating speed is slower, it also requires higher precision. The extremely high deformation resistance of cemented carbide guide rollers can ensure the accuracy of the electrode wire path and avoid data errors during processing.

In hot rolling production lines and wire drawing equipment, metal will move repeatedly at high speed along the predetermined route through the guide roller groove, and finally achieve the processing purpose of plastic deformation of metal materials. Cemented carbide guide rollers are undoubtedly the core components of metal rolling and wire drawing equipment. Such a high temperature and high friction working environment requires high material quality of the guide roller. During the rolling process, the pressure can reach hundreds of MPa, and the hot rolling temperature can reach 800-1200 degrees Celsius. In such an environment, the carbide guide roller can still remain stable and not deformed. While ensuring the processing accuracy, it can avoid economic losses caused by frequent equipment maintenance.

Like other mining equipment parts, the guide rollers in mining and engineering machinery often act on conveyor belts, crushers and other parts, and need to withstand severe wear of ore and sand. 24-hour non-stop operation, high load and severe wear are particularly obvious in such a working environment. Guide rollers made of traditional materials often lead to extremely high failure rates and maintenance frequencies.

High-precision processing, hundreds of cycles of operation, such an operating environment puts higher requirements on the compressive strength and wear resistance of all its components. More and more manufacturers favor carbide guide rollers. In the process of material transportation and motion positioning, this excellent material can often avoid failures.
