      Product Details

      Product Introduction

      The continuous rolling mill achieves continuous plastic deformation of metal materials by connecting multiple rolling mills in series. Its core principle is based on the equal second flow model, meaning the volume flow of metal between each stand remains constant. Uniformity of the strip thickness (with an accuracy of ±5μm) is ensured through speed matching and tension control.

      The equipment consists of reducers, motors, universal joint shafts, roller systems, etc., and supports four-high, six-high or twelve-high stand configurations, suitable for the production of high-precision sheet and strip materials.

      ★Cold Continuous Rolling Mill

      Using hot-rolled coils as raw materials, after pickling, they are rolled through multiple stands, with thickness accuracy reaching ±1μm. It is used for high surface quality products such as home appliance panels and car bodies.

      Frequently Asked Questions (FAQ)

      Q1 What is the core working principle of a continuous rolling mill?
      The continuous rolling mill operates on the equal second flow model, where the volume flow of metal through each stand remains constant. Multiple rolling mills are connected in series, and through precise speed matching and tension control, the metal strip is continuously deformed to achieve the target thickness with high accuracy.
      Q2 What thickness accuracy can the cold continuous rolling mill achieve?
      The cold continuous rolling mill achieves a strip thickness accuracy of ±1μm, making it suitable for high surface quality applications such as home appliance panels, automotive body panels, and other precision sheet products.
      Q3 What stand configurations are available for the continuous rolling mill?
      The continuous rolling mill supports multiple stand configurations, including four-high, six-high, and twelve-high arrangements. Each configuration is suited for different product requirements, ranging from standard sheet production to ultra-thin, high-precision strip materials.
      Q4 What materials can be processed by these rolling mills?
      The mills listed in the technical parameter table are designed to process carbon steel and low alloy steel. The input material thickness ranges from 2.0 to 3.0 mm (hot-rolled coil after pickling), and the finished product thickness can be reduced to as thin as 0.40 mm.
      Q5 What control system is used for the rolling mill's drive and automation?
      The mills are equipped with Siemens 6RA70 DC speed regulators for precise motor control and Siemens PLC systems for electric control and automation. The pressing method uses Hydraulic AGC (Automatic Gauge Control) to maintain consistent strip thickness throughout the process.
      Q6 Can the rolling mill be customized to meet specific production requirements?
      Yes. All technical parameters — including mill model, rolling speed, pressing force, roll specifications, and strip width — can be tailor-made according to the user's specific requirements. The table values are provided as a reference baseline for standard configurations.
