High Density Tungsten Carbide Roller Round Shape Surface Polished ISO 9001 Approved
Tungsten Carbide Rolls as the characters of high wear resistance, high corrosion resistance and good compressive properties which is an important parts in the steel bar and wire rod rolling. The rolls are primarily applied in high speed wire line, Kocks three roll mill, seamless pipe stretch reducing mill, three dimensional rolls for cold-rolled ribbed steel bar, and composite roll for hot-rolled bar screw thread steel etc.

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. | |||||
