Why cooling is important for the tungsten carbide rollers during its working?
Well, cooling is to reduce the effect of hot corrosion, thermal fatigue and thermal stress on the rollers during the roller rolling, to prevent roller ring breakage, delay crack propagation, extend groove life, which play an important role in the performance of tungsten carbide rollers.
how to choose the cooling water for tungsten carbide rollers?
The reference specifications for cooling water are as follows:
1. The temperature of the cooling water should be lower than 25 ° C;
2. The pressure of the cooling water (5-6) bar;
3. The amount of water (24-30) m3 / hour frame;
4. The water spray should be radial, with a direction at 15-30 degrees of the roller;
5. The width of the water column is twice that of the groove and should be sprayed directly into the groove. The water cannot be scattered or fogged.
Water quality requirements for different material grade series:
YGH series is required for neutral or weak alkaline water quality with pH ≥ 7.2;
YGR series can use slightly acidic water with PH≥7.2 or PH≤7.2;
Solid content in water <15 mg / liter.
