Professional HIP Sintering Tungsten Carbide Seal Rings Abrasion Resistance
Product Description
1. Mechanical seal ring are used to seal the clearance between the rotating shaft and the stationary housing in equipment .Tungsten carbide is the most excellent seal face material in the seal material world.
2. The cemented carbide seal ring can be divided into both of the rotating seal ring and static seal ring, and constitutes mechanic seal together with the spring, rubber seal-ring and steel jecket.
3. Tungsten carbide seal ring be used mainly for waste water pump, water discharge pump for the mines, centrifugal pump, centrifuge, slag slurry pump and slurry pump in the adverse working conditions of high speed rotation, sand flush abrasion and corrosion. The seal-ring will be installed on the pump body and rotating axle, and forms through the end face of the rotating and static ring a liquid or gas seal.
4. One of main reasons for using tungsten Carbide is the additional wear resistance that can be achieved in both moving and static parts.This is particular the case in serve service conditions, such as high temperature,and high levels of corrosion and abrasion.
5. Mechanical Seal ring raw material: tungsten carbide nickel binder, tungsten carbide cobalt binder, silicon carbide, carbon and graphite.
6. Normal grade only for reference about tungsten carbide, we also can custom the material grade as per request from our customer.
Grade and Recommended Application:
| Grade | Density (g/cm³) | Hardness (≥HRA) | Strength (Mpa) | Recommended application |
| YG20 | 14.30-14.50 | 86.5 | 2500 | Maximum hardness,excellent wear resistance.Mostly for the last 1-2 stands of good high speed bars. |
| YG25 | 14.10-14.30 | 85.5 | 2520 | Higher wear resistance and moderate impact resistance in the series.Mostly for the last 1-3 stands of good high speed bars. |
| YG30 | 13.90-14.10 | 84 | 2520 | Moderate wear resistance and impact resistance.Good for general purpose.Used in the last 1-4 stands or all stands or finishing mills. |
| YG40 | 13.60-13.80 | 83.5 | 2570 | Best for general purpose.Mostly for the front stands of good mills and in the rear stands of common mills. |
| YG45 | 13.45-13.65 | 82.5 | 2570 | Used in the first and second stands of finishing mill and in the stands of pre-finishing rolling mills . For every milling lines of low speed rolling, low precision and unstable operation. |
| YG55 | 12.90-13.10 | 81 | 2570 | Maximum binder content in YGH series Good toughness and thermal crackresistance. For every milling lines for low speed rolling, low precision and unstable operation. Mostly for the stands of pre-finishing rolling mills and hot rolling of cribbed steel. |
