ATOX roller repair, maintenance, production

1. Product positioning
Full-cycle service expert for vertical mill rollers
CNBM Qinhong provides an integrated solution of repair-maintenance-customized manufacturing based on the high stress and high wear working conditions of ATOX vertical mill rollers. Relying on gradient composite repair technology + intelligent remanufacturing process, it can extend the service life of cement raw materials, slag grinding and other scenes by 3-5 times after repair, reduce the comprehensive operation and maintenance cost by 50%, and adapt to the full range of ATOX 30-60 roller systems

2. Core technology analysis

1. Repair technology innovation

Four-dimensional composite repair system:
Surface strengthening: tungsten carbide plasma cladding (Hv2200), wear resistance increased by 60%6
Matrix reconstruction: Solei polymer metal polymer material (compressive strength 179MPa), fill the wheel hub wear gap to 0.05mm accuracy26
Stress optimization: ANSYS simulation reverse modeling, eliminate local stress concentration (residual stress reduced by 35%)4
Seal upgrade: ceramic-based composite sealing ring, temperature resistance increased to 220℃3
2. Intelligent remanufacturing process

Laser cladding repair: layer thickness control accuracy ±0.1mm, interface bonding strength >550MPa6
Gradient heat treatment: five-stage temperature control (including cryogenic treatment), hardness uniformity error <1.5HRC5
Digital twin detection: based on 3D scanning reverse modeling, dimensional adaptation tolerance ±0.3mm4
3. Preventive maintenance system

Lubrication intelligent monitoring: real-time monitoring of return oil temperature (fluctuation value <3℃), vacuum negative pressure (-0.45~-0.25bar)3
Wear warning system: predict the risk of liner cracks through vibration spectrum analysis (amplitude <5mm/s)
III. Full-cycle service scenario
1. Damage repair service

Wheel wear: fill the gap > 6mm plastic deformation (100% contact surface fit after repair) 6
Liner crack: handle stress cracks with a depth of ≤50mm (98% compression recovery rate) 2
Bearing failure: quickly replace SKF/FAG customized bearings (installation accuracy ±0.02mm) 3
2. Preventive maintenance service

Lubrication system optimization: 8000h oil replacement cycle, real-time monitoring of filter element dirtiness 3
Sealing system upgrade: quarterly addition of high-temperature grease (temperature resistance >200℃) 5
3. Customized manufacturing service

Non-standard liner: support Cr26/Cr30 material gradient composite design (thickness error ±0.5mm) 1
Smart roller sleeve: integrated stress sensor (data sampling rate 100Hz)
