Roller press sleeve production, replacement 2

Customized production and replacement service for roller press sleeves——China National Building Materials Qinhong (Hubei) New Materials Co., Ltd.
I. Service background
The roller press sleeve is the core wear-resistant component of the grinding system. It is subjected to high pressure, high impact and material wear for a long time, and is prone to surface peeling, cracks, dimensional deformation and other problems, resulting in reduced grinding efficiency and increased energy consumption.
China National Building Materials Qinhong (Hubei) New Materials Co., Ltd. focuses on the research and development and manufacturing of wear-resistant materials, providing customized production and professional replacement services for roller press sleeves, from material selection to installation and commissioning, to help customers achieve efficient, stable and low-consumption production.

II. Core technology for roller sleeve production
Selection of high-performance materials

Using wear-resistant materials such as high chromium alloy (Cr20-Cr30) and tungsten carbide composite materials, the hardness reaches HRC60-65, and the impact toughness is increased by 50%.

The material formula can be customized according to the material characteristics (such as hardness and humidity) to extend the service life of the roller sleeve by more than 30%.

Precision casting process

Vacuum casting + directional solidification technology, reduce pores and slag inclusion defects, material density ≥ 98%.

Combined with computer simulation to optimize structural design, avoid stress concentration and improve fatigue resistance.

CNC precision machining

Large CNC machine tools process the roller sleeve surface, with a dimensional accuracy of ±0.05mm and a surface finish of Ra≤0.8μm.

Strictly match the original parameters of the equipment to ensure the uniformity of the roller gap and smooth operation.

Heat treatment strengthening

Multi-stage quenching + low-temperature tempering process to balance the hardness and toughness of the material and reduce the risk of cracking during use.

The surface hardness uniformity error is ≤2HRC, and the wear-resistant life is increased by 2-3 times year-on-year.
