The 18-HI cold rolling machine is an industrial equipment used for precise processing of metal materials. Its main functions and effects include:
Efficient metal forming: Through multiple passes of cold rolling, it deforms steel, stainless steel, aluminum and other metal materials, significantly improving the surface quality and dimensional accuracy of the materials. Its small-diameter working rolls (about 30% of traditional four-roll mills) combined with side support technology can effectively prevent lateral deviation of the rolls and achieve a more stable rolling process.
Enhanced material performance: During the cold processing, the crystal stability of the material's central section is retained, while the tensile strength, yield strength and elongation are increased, making the finished products suitable for high safety-level construction and industrial applications.
Technical advantages: The patented side support system (mechanical/hydraulic) ensures the stability of the working rolls; the axial movement technology of the middle roll axis enhances the flexibility of the rolling process; energy-efficient and highly efficient, suitable for the production of advanced materials such as high-strength steel;
The characteristics of the 18-HI cold rolling machine can be summarized as follows:
1. Innovative roll system structure: Small-diameter working rolls (about 30% of traditional four-roll mills) combined with the side support system (mechanical/hydraulic) prevent lateral deviation, significantly improving the rolling stability. Multi-row supporting roll layout: 18 supporting rolls are arranged in three rows in sequence, providing excellent isotropic rigidity and capable of withstanding high rolling forces and strip tension.
2. High precision control capability: Forming system: Through the axial movement of the middle roll, bending force and tilting roll technology, dynamic form control is achieved, reducing edge thinning and wave-shaped defects. Automated thickness control (AGC): Using high-precision sensors and servo valves, the thickness control accuracy can reach ±2.5 μm, suitable for ultra-thin strip steel production.
3. Efficient rolling process
High-pressure reduction design: Small working rolls combined with high-torque transmission support single pass large reduction rate rolling, reducing the annealing process. Automatic roll changing system: Robots quickly replace the working rolls, middle rolls and side support rolls, shortening downtime.
4. Material adaptability
High-strength steel processing capability: Specifically designed for high-strength materials such as stainless steel and silicon steel, the rolling width can reach 200mm, and the thinnest thickness is 0.3mm. Energy-saving and environmentally friendly: Compared to traditional mills, energy consumption is reduced by more than 40%, and no acid washing pretreatment is required, reducing pollution.
