One Driven One Continuous Rolling Mill Unit

One Driven One Rolling Mill Unit:

One driven one rolling mill Unit is a critical component in hot rolling production lines, typically composed of a roughing mill group (roughing mill) and a finishing mill group (finishing mill). Here is a detailed overview of the one driven one rolling mill:

1. Roughing Mill Group:

Structural Features: The roughing mill group consists of three sets of rolls—upper, middle, and lower. Rolls are typically made of high-strength alloy tool steel to ensure sufficient hardness and wear resistance.

Operating Principle: Steel billets pass through the gap between the upper and middle rolls. Through the rotation and compression of the rolls, the initial plastic deformation of the steel billet is achieved, gradually reducing its thickness.

Roll Gap Adjustment: Equipped with an advanced roll gap adjustment mechanism, the width of the gap can be precisely controlled to accommodate different specifications and requirements of hot-rolled steel billets.

2. Finishing Mill Group:

Structural Features: The finishing mill group typically includes upper and lower sets of rolls. These rolls are often made of high-quality tool steel or hard alloy rolls to ensure high-precision rolling.

Operating Principle: After the initial rolling in the roughing mill group, the steel billets enter the finishing mill group. Here, through the rotation and compression of the upper and lower rolls, further plastic deformation is achieved, resulting in a more refined and uniform thickness.

Temperature Control: To ensure rolling quality, precise control of the temperature of the steel billets is often necessary to maintain the appropriate temperature range for rolling.

3. Application Areas:

One driven one rolling mill is widely used in the production of various hot-rolled products, such as plates, strips, etc. It particularly excels in areas where high surface quality and dimensional accuracy are required.

4. Advantages and Characteristics:

Efficient Production: Through continuous roughing and finishing processes, the mill achieves efficient production.

High-Precision Rolling: The design and control systems of the finishing mill group enable high-precision rolling, ensuring the final product meets specified dimensional and surface quality requirements.

Versatility: Adaptable to various types and specifications of hot-rolled steel billets, demonstrating strong production flexibility.

5. Considerations:

Maintenance: Regular maintenance of equipment, including inspections and lubrication of rolls, is essential to ensure stable and prolonged operation.

Safety Operations: Operators must adhere to strict operational procedures and safety standards to ensure a secure production process.

In conclusion, the one driven one rolling mill plays a crucial role in hot rolling production lines, providing essential processing for the production of high-quality and high-precision hot-rolled products.
