Composite rolls are composites or combinations of cemented carbide roll rings and matching steel shafts using a special method. They are used for rolling round steel, rebar, square steel, flat steel, angle steel and other profiles.
1. Advantages of carbide composite rollers
2. 1. It increases the output of steel products, improves the surface quality and tolerance of rolled materials more thoroughly, and the negative deviation control is very accurate.
3. 2. Reduce the number of groove changes, roll changes and downtime, reduce the labor intensity of employees in the rolling workshop, improve the utilization rate and output of the rolling mill, and enable the rolling mill to create greater economic benefits in the same time
4. 3. Improve product yield
5. 4. Reduce the cost per ton of steel.
According to customer requirement of different grades of cemented carbide rolls have different hardness and strength. They are suitable for different machine frames and must be selected correctly. The cemented carbide roll ring grades selected for the cemented carbide grade composite rolls produced by our company are as follows:
Grade | Chemical Composition | Density | Hardness | Bending Strength | Young's modulus of elasticity | thermal conductivity | Grain size | |
WC | Binding | g/mm3 | HPA | N/mm2 | KN/mm2 | Sec/°C | ||
TW55 | 79.50 | 25.34 | 13.05 | 80 | 2700 | 446 | 66 | 3-6 um |
TW60 | 79.00 | 28.50 | 12.95 | 79.5 | 2600 | 425 | 57 | 3-6 um |
Supporting technical services:
