China Skin Pass Mill Factory: High-Quality Suppliers for CR Strip Coil Processing Equipment

,

MAIN FUNCTION OF EQUIPMENT

,

The CR strip coil undergoes a flattening process with a small reduction rate, which effectively eliminates certain levels of stress and elongation of the yield point. This ensures that during stretching and punching, the slip line phenomenon is prevented.

,

Post-annealing, the CR coil strip is subjected to tempering, significantly enhancing both its flatness (coil shape) and surface roughness.

,

By fine-tuning the reduction rate during the tempering process, we can achieve a specific range of mechanical properties, allowing the hardness and plasticity of the coil strip to meet diverse functional requirements.

    Frequently Asked Questions (FAQ)
    Q What materials are compatible with these temper mill models?
    All four models (650, 750, 850, and 1000) are compatible with both normal carbon steel and stainless steel, making them suitable for a wide range of industrial processing applications.
    Q What is the maximum material thickness that can be processed?
    The maximum material thickness across all models is 1.5 mm. The Model 650 supports thicknesses from 0.16 mm to 1.5 mm, while models 750, 850, and 1000 support a range starting from 0.3 mm up to 1.5 mm.
    Q Which model offers the highest line speed?
    The Model 1000 offers the highest line speed, ranging from 240 to 600 m/min, making it the best choice for high-throughput production environments requiring fast processing speeds.
    Q What is the difference between the 2-roll and 4-roll tempering mill types?
    The 2-roll type is simpler in structure and suitable for lighter processing tasks, while the 4-roll type provides better rolling stability and force control, making it ideal for demanding applications. Models 650 and 750 offer both options, whereas models 850 and 1000 use the 4-roll type exclusively.
    Q Can the equipment parameters be customized according to specific production requirements?
    Yes. All models and parameters listed in the table are for reference only. The design and production of the equipment can be fully tailor-made according to the user's specific requirements, including material type, width, thickness, and speed preferences.
    Q What type of motor is used across all models, and what does "omit" mean?
    All models use Z4 series DC motors for the main motor, uncoiler motor, recoiler motor, and S roll motor. The notation "(omit)" indicates that the specific power rating or detailed motor specification is not listed in this reference table and will be determined based on customized project requirements.
