      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.

      🔄 Process Flow: Hot Coil Pickling → Multi-Stand Rolling → Annealing → Tempering

      Supports headless rolling technology to enhance continuity.

      Frequently Asked Questions (FAQ)

      Q What is the core working principle of a continuous rolling mill?
      The continuous rolling mill operates based on the equal second flow model, which ensures the volume flow of metal remains constant between each rolling stand. Speed matching and tension control are used to maintain uniform strip thickness with an accuracy of ±5μm throughout the continuous rolling process.
      Q What stand configurations are available for the continuous rolling mill?
      The continuous rolling mill supports four-high, six-high, and twelve-high stand configurations. These configurations make the mill suitable for the production of various high-precision sheet and strip materials, depending on the specific requirements of the application.
      Q What thickness accuracy can the cold continuous rolling mill achieve?
      The cold continuous rolling mill can achieve a thickness accuracy of ±1μm. This extremely high precision makes it ideal for manufacturing high surface quality products such as home appliance panels and automotive body components.
      Q What materials are compatible with these rolling mill models (650 / 750 / 850)?
      All three mill models — 650, 750, and 850 — are compatible with carbon steel and low alloy steel. The input material thickness ranges from 2.0 to 3.0 mm, and the mills can reduce it to a finished thickness between 0.40 and 0.6 mm.
      Q What control systems are used for the rolling mill's speed and automation?
      The rolling mills use Siemens 6RA70 DC speed regulators for precise speed control and Siemens PLC for overall electric control and automation. The pressing method employs Hydraulic AGC (Automatic Gauge Control) for consistent and accurate thickness control.
      Q Can the rolling mill be customized to meet specific production requirements?
      Yes. The models and parameters listed in the technical table are provided for reference only. The design and manufacturing of the rolling mill can be fully tailor-made according to each customer's unique production requirements, including material width, rolling speed, pressing force, and other specifications.
