Three Dimensional Cemented Carbide Roll

3-dimensionall cemented carbide roll rolled ribbed steel appearance quality, dimensionally accurate, clear the ribs, while improving the overall performance of the reinforced. 3-dimensional cemented carbide roll repeatable grinding, grinding rolling capacity can reach 600 to 2000 tons, compared with ordinary tool steel rolls 20-30 times, which can effectively reduce production costs, improve production efficiency.

Note:
1.The specifications in the table are recommended for use. We can also produce roll rings according to the drawings provided by customers.
2. The grooves of the roll rings can be designed and manufactures according to GB13788-2000 standard and they can also be designed based on customers' requirements and marked in a special way.
3. We can supply compatible tool steel systems to customers for assisting them with modifying their mills and rolling process.

Application requirements of 3-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 bearing 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 any internal cooling is not to be applied.
