Product Description

Tungsten Carbide Corrugated Paper Rolls And Rolls


product description:
The super wear-resistant tungsten carbide corrugated paper roll grinding shaft material is made of 50CrMoA alloy steel forgings. The hardness and the wear resistanceis second only to diamond. It is suitable for high-speed operation of corrugated paper to reduce vibration and noise.
Technical specifications of super anti-friction tungsten carbide coated corrugated roll
1. 48CrMo alloy steel precision forgings for corrugated rollers
2. Intermediate frequency quenching> HRC58 hardness
3. The thickness of the wear-resistant tungsten carbide coating is between 0.06mm and 0.08mm
4. Microhardness of tungsten carbide coating> HV1250-1400
5. Comprehensive hardness> 75MPa
6. Visible metallographic porosity<0.1
7. Optimized design of economical corrugated paper sample
8. High-speed roller accuracy

Advantange corrugated roll:
1. The coating is firmly combined with the substrate to ensure long-term use of the coating without falling off;
2. The hardness of the coating is high, the wear resistance is doubled, and the life is linearly extended;
3. The coating thickness is uniform and controllable, which can ensure the accuracy of the corrugated wheel;
4. The surface roughness before coating can reach ra0.3-0.5um. After grinding with a special diamond grinding wheel cutter, the surface roughness reaches and is higher than that of the electroplated hard chrome roller.
5. With UV-type and UVV-type corrugated design, it can effectively improve the hardness of the cardboard and reduce the amount of paste and the waste of core paper;
6. When the corrugated type is used, there will be abrasion in theory, and the paper output rate will remain unchanged for a long time;
7. Since the corrugating roller used this machine, the thickness of the cardboard produced remains unchanged, the printing is always smooth, and the quality of the cardboard and cartons is stably controlled;
8. Using special methods to remove the coating, the wheel blank can be reused;
9. The extension of the service life reduces the frequency of replacement, and also saves labor and material costs;
