Introduction and Application for tungsten carbide cold rolls: Tungsten carbide roller has high hardness, and their hardness values change little with temperature. Its hardness at 700°C is 4 times that of HSS.And the elastic modulus, compressive strength, bending strength, and thermal conductivity are also higher than the tool steel by more than one time.Due to the high thermal conductivity of the tungsten carbide rolls, the heat dissipation effect is good.Therefore, the cemented carbide rolls are more resistant to corrosion and cold and heat fatigue than the tool steel roll.
Tungsten carbide rollers main used to produce smooth or ribbed wire for construction reinforcement filed.
Some sizes of tungsten carbide cold rolls:
| Wire Range(mm) | O.D.(mm) | I.D.(mm) | Thickness(mm) |
| 4~8.5 | 123 | 82 | 15 |
| 9~12 | 123 | 82 | 20 |
| 4~8.5 | 125 | 82 | 15 |
| 9~12 | 125 | 82 | 20 |
| 4~8.5 | 140 | 90 | 15 |
| 9~12 | 140 | 90 | 20 |
| 4~8.5 | 150 | 90 | 15 |
| 9~12 | 150 | 90 | 20 |

||||
| E10M | 10 | 14.3 | ≥86.0 | Maximum hardness,excellent wear resistance in the grade series of tungsten carbide rolls.Used in the last 1-2 stands of good high speed finishing mills for rolling common and hard steel bars. |
| E12M | 12 | 14.2 | ≥84.0 | Higher wear resistance,moderate impact resistance in the series of cemented carbide rollers.Used in the last 1-3 stands of good high speed finishing mills for rolling common and hard steel bars. |
| E15M | 15 | 14.0 | ≥83.5 | Moderate wear resistance and impact resistance,good for general purposes.Used in the last 1-4 stands or all stands of finishing mills. |
| E18M | 18 | 13.8 | ≥83.0 | Best for general purposes.Used in the front stands of good mills and in the rear stands of common mills. |
| E20M | 20 | 13.7 | ≥82.0 | Used in the first and second stands of finishing mills and in the stands of pre-finishing rolling mills.For every stand of rolling lines for low speed rolling,low precision and unstable operation. |
| E26M | 26 | 13.2 | ≥81.0 | Maximum binder content in the grade series of tungsten carbide rollers.Good toughness and thermal crack resistance.Used in the stands of the pre-finishing rolling mills and for rolling for hot rolling of ribbed steel. |
