Industrial Metal Rolling Mill

Product Specifications

Technical details and manufacturing context for Industrial Metal Rolling Mill

Definition

An industrial metal rolling mill is a standalone machine used in basic metal manufacturing to reduce the cross-sectional area of metal workpieces through compressive forces applied by rotating rolls. It transforms ingots, billets, or slabs into sheets, plates, bars, or structural shapes with precise dimensional control. The machine is essential for producing semi-finished metal products with improved mechanical properties and surface quality. Rolling mills operate at various temperatures (hot, warm, or cold) depending on material requirements and final product specifications. The equipment typically includes a housing, work rolls, backup rolls, drive motors, and a control system for roll gap adjustment. The rolling process involves passing the metal between counter-rotating rolls that apply compressive stress, causing plastic deformation and reducing thickness while increasing length. The mill can be configured for different product types, such as flat rolling for sheets and plates or shape rolling for bars and structural sections. Key parameters include maximum rolling width, rolling speed, motor power, thickness reduction ratio, roll gap adjustment, maximum entry thickness, roll diameter, rolling force, rolling temperature, electrical supply, operating temperature, ingress protection, and machine weight. These parameters are reference ranges that must be confirmed for the specific model and application. The machine is designed for use in basic metal manufacturing facilities, and its selection depends on the material to be processed, desired output dimensions, and production capacity. Proper maintenance and operation are critical to ensure consistent product quality and equipment longevity. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement or use.

Working Principle

The metal workpiece passes between two or more counter-rotating rolls that apply compressive forces, reducing thickness while increasing length through plastic deformation. The rolls are typically made of high-strength alloy steel, tungsten carbide, or chromium-molybdenum steel. The gap between the rolls is precisely adjusted to control the final thickness. As the metal is drawn through the rolls, it undergoes plastic deformation, which changes its shape and improves its mechanical properties. The process can be performed at hot, warm, or cold temperatures, depending on the material and desired outcome. The rolling force and speed are controlled to achieve the required reduction and surface finish.

Frequently Asked Questions

What is the typical range for maximum rolling width?

According to the reference data, the maximum rolling width is typically between 1000 and 2500 mm. However, this value must be confirmed for the specific model and application with the manufacturer.

What materials are commonly used for the rolls?

The rolls are commonly made from high-strength alloy steel, tungsten carbide, or chromium-molybdenum steel. The choice depends on the material being rolled and the required performance.

What is the significance of the rolling temperature?

Rolling temperature affects material properties and roll life. For hot rolling, the temperature typically ranges from 900 to 1200 °C. The appropriate temperature depends on the metal and desired final properties.

What electrical supply is required?

The electrical supply is typically 380–690 V AC, with a frequency of 50/60 Hz, according to IEC 60038. However, the exact requirements must be verified with the manufacturer for the specific installation.
