Solid Tungsten Carbide Rings High Wear Resistance Size Customized Round Shape
Advantage of the material tungsten carbide:
Tungsten carbide rollers possess good thermal conduction property.
Compared with other materials ,it is much better in term of heat-resistance,
wear-resistance and strength.
Its hardness reduce a litte under the condition of high temperature.

Grade Application
Grade | Recommended appication | |||||
YGR20 | High wear resistance and corrosion resistance. Used in the last 1~2 stands of dinishing mills. | |||||
YGR25 | High wear resistance and corrosion resistance. Used in the last 1~3 stands of dinishing mills. | |||||
YGR30 | Good toughness, wear resistance, corrosion resistance and thermal crack resistance. Used in the middle and rear of finishing mills. | |||||
YGR40 | Good toughness and thermal crack resistance, good for general purposes. Used in most standards of the finishing mills and in the rear stands of common mills. |
|||||
YGR45 | Good toughness and thermal crack resistance. Used in the front stands of finishing mills. | |||||
YGR55 | Good impact resistance. Used in the standards of pre-finishing rolling mills for hot rolling ribbed steel bars and they can be machined with turning and milling. |
|||||
YGR60 | Good impact resistance. Used for hot rolling ribbed steel bars and in the first and second stands of pre-finishing rolling mills. | |||||
YGH05 | The WC content of the grades is higher than that of other roll grades used in high-speed wire mills. They have higher hardness and wear resistance properties. Because tungsten carbide has excellent heat transfer property, the high WC content will increase the ability of hot cracking resistance. These characteristcs of the grades can make the rolled wires with regular shape and good surface quality. At the same time, the high fracture toughness make them enough to bear mechanical stress during rolling. |
