    High-Quality Skin Pass Mill Equipment from China Suppliers and Factory for Improved Strip Flatness and Surface Quality

    ,

    MAIN FUNCTION OF THE EQUIPMENT

    ,

    The CR strip coil undergoes a controlled flattening process with a low reduction rate, which effectively reduces stress and elongation at the yield point. This process ensures that during stretching and punching operations, there is no appearance of slip lines on the strip coil.

    ,

    Following the annealing process, the CR coil strip is treated with tempering to significantly enhance its flatness and surface roughness, making it ideal for various applications.

    ,

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

    ,

      Frequently Asked Questions
      Q1 What materials are compatible with these temper mill models (650, 750, 850, 1000)?
      All four models — 650, 750, 850, and 1000 — are compatible with both normal carbon steel and stainless steel. The machines are engineered to handle a range of material thicknesses from 0.16 mm up to 1.5 mm depending on the specific model selected.
      Q2 What is the maximum line speed available across these temper mill models?
      The highest line speed is offered by the Model 1000, which can reach up to 600 m/min. Models 650 and 750 support speeds of 180–300 m/min, Model 850 supports 180–400 m/min, making the 1000 series the best choice for high-speed production requirements.
      Q3 What is the difference between the 2-roll and 4-roll tempering mill configurations?
      The 2-roll configuration is available on Models 650 and 750 and is suitable for lighter processing requirements. The 4-roll configuration, available across Models 650, 750, 850, and 1000, provides greater rolling force and precision, making it ideal for heavier or more demanding steel processing applications.
      Q4 Can the temper mill parameters be customized to suit specific production needs?
      Yes. As stated in the product specifications, all models and parameters shown in the table are for reference only. The design and production of each machine can be fully tailor-made to meet individual user requirements, including material type, thickness range, line speed, and tempering force.
      Q5 What type of motors are used for the main drive, uncoiler, recoiler, and S roll?
      All four models use the Z4 series motors for the main motor, uncoiler motor, recoiler motor, and S roll motor. The specific motor ratings are omitted from the standard parameter table, as they are typically determined based on customized production configurations.
      Q6 What hydraulic station pressure is required for these temper mills?
      All models — 650, 750, 850, and 1000 — operate at a standard hydraulic station pressure of 10 MPa. This consistent pressure requirement across all models simplifies hydraulic system integration and maintenance in production environments.
