Roller body assembly to be repaired

1. Product Positioning
Vertical Mill Roller Regeneration Service Expert
CNBM Qinhong (Hubei) New Materials Co., Ltd. has been deeply engaged in the field of wear-resistant materials for more than 20 years. Relying on high-chromium cast iron technology and composite surfacing technology, it provides roller assembly full life cycle repair services for cement, power, mining and other industries. Through independently developed gradient composite materials and intelligent remanufacturing processes, the service life after repair is extended by 3-5 times, and the comprehensive operation and maintenance cost is reduced by 50%. It is suitable for the full range of vertical mill models such as ATOX, CK, and MPS, and overcomes the industry pain points such as thermal deformation and long return cycle of traditional surfacing repair.

2. Core Technology Analysis
1. Composite surfacing technology

Gradient wear-resistant layer design:
The composite structure of tungsten carbide cladding layer (Hv2200) + high chromium cast iron transition layer (Cr26, HRC62-65) is adopted, and the wear resistance is improved by 60%1, and the bonding strength is greater than 550MPa.
Dynamic stress optimization:
Based on ANSYS simulation reverse modeling, local stress concentration is eliminated, residual stress is reduced by 35%, and the risk of plastic deformation is avoided.
2. Intelligent remanufacturing process

3D laser scanning modeling: reverse engineering accuracy ±0.3mm, suitable for non-standard wear rollers.
Five-stage gradient heat treatment: intelligent temperature control quenching (including -80℃ deep cold treatment), hardness uniformity error <1.5HRC.
3. Rapid repair capability

72-hour on-site repair: no need to return to the factory, the contact area of the groove with a single-side wear of >8mm is restored to more than 98% after repair.

III. Typical application scenarios

Cement industry: suitable for vertical mills of Conch, China Resources, Huaxin and other groups, the power consumption of grinding is reduced by 1.8kWh/t after repair.
Slag grinding: processing high-hardness materials (Bond index >35kWh/t), the hourly output is increased by 15%.
Power industry: Cooperate with five major power generation groups to repair the roller assembly with a temperature resistance of ＞250℃
Fourth, service guarantee system

1. Quality commitment

ISO 9001/GB/T 33947 certification, warranty period of 18 months.
Each batch comes with a metallographic test report + 3D stress cloud map.
