China Skin Pass Mill Suppliers - High-Quality Tempering Mill for Steel Strips | Factory Direct Equipment

,

MAIN FUNCTION OF THE EQUIPMENT

,

The CR strip coil undergoes a flattening process with a small reduction rate, effectively reducing stress and elongating the yield point. This process ensures that during stretching and punching, the strip coil avoids any slip line formation.

,

Post-annealing, the CR coil strip is treated through a tempering process, enhancing both the strip's flatness (coil shape) and surface roughness significantly.

,

By adjusting the tempering reduction rate, manufacturers can achieve a specific range of mechanical properties for the coil strip, thus tailoring its hardness and plasticity to meet various 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 sheet metal processing applications.
    Q What is the material thickness range each model can handle?
    The Model 650 handles material thickness from 0.16 mm to 1.5 mm. Models 750 and 850 support 0.3–0.8–1.5 mm ranges, while the Model 1000 covers 0.3–1.5 mm, catering to both thin and medium-gauge materials.
    Q Which model offers the highest line speed, and what is it?
    The Model 1000 offers the highest line speed, ranging from 240 to 600 m/min. This makes it ideal for high-productivity production lines requiring faster processing throughput.
    Q What types of tempering mills are available across the different models?
    Models 650 and 750 offer the flexibility of either a 2-roll or 4-roll tempering mill configuration, while Models 850 and 1000 are equipped with a 4-roll tempering mill for greater rolling force and stability at higher speeds.
    Q Can the temper mill specifications be customized to meet specific production requirements?
    Yes. All models and parameters listed in the table are for reference purposes only. The design and production of each unit can be fully tailor-made according to the customer's specific operational requirements and technical standards.
    Q What is the hydraulic station pressure used across all models, and what motor series is applied?
    All four models operate at a hydraulic station pressure of 10 MPa. The main motor, uncoiler motor, recoiler motor, and S roll motor all use the Z4 series (specific power ratings are customized based on user requirements and are omitted from the standard reference table).
