Application requirements of dimensional cemented carbide roll rings
|
1. Any striking on and collision with roll rings is strictly prohibited. |
2. When installing the whole assembly of roll rings, the clearance of the bearings in relation to the casings should be on the tighter side .
|
3. The precision of rotation of the whole assembly ( circular runout and end runout ) should be kept within ±0.05mm.
|
4. The fitting -in of the whole assembly and the roll rings shall be a transitional fitting -in and fastened.
|
5. The roll rings should not be cooled by water or oil water emulsion.
|
| 6. The joints of the pipes in the internal cooling system should not be leaky and it is advisable that no cooling is applied. |
Tungsten Carbide Roll Ring as the characters of high wear resistance, high corrosion resistance and good compressive properties. It's widely used in petrochemical industries and other industries which call for high properties of the mechanical sealing rings or prats.
We can offer roll rings with different dimensions and can also
produce roll according to your special requirements, like making
groove before the sintering which can shorten the delivery time
effectively and leave out the expensive and time-consuming
machining process for you.
