Collection Roll Device

Collection Roll Device in Hot Rolling Mill

1. Structure and Components:

Coiling Shaft: The core component of the collection roll device is the coiling shaft, used to wind metal sheets or strips. The design of the coiling shaft depends on the specifications and process requirements of the coiling material.

Straightening Rolls: The device typically includes a series of straightening rolls used to adjust the shape and surface of the metal material, ensuring that the coiled material has consistent thickness and flatness.

Drive System: The collection roll device is equipped with a drive system, including an electric motor, reducer, and coupling, to ensure the smooth operation of the coiling process.

2. Functions and Applications:

Straightening and Coiling: The primary function is to straighten the metal material using straightening rolls and then coil it onto the coiling shaft. This contributes to the production of high-quality and consistently sized coils.

Shape Adjustment: The design and layout of the straightening rolls allow for the adjustment of the shape of the metal material, ensuring that the coiled material meets the required geometric specifications.

Speed and Tension Control: By controlling the speed of straightening and coiling, as well as the tension on the coiling shaft, the device ensures that the coiled material maintains proper tension and speed throughout the process.

Coil Conveyance: The coiled metal coil can be further processed or transported to downstream processes through a conveying system.

3. Features and Advantages:

Efficient Coiling: The design of the device enables efficient straightening and coiling of metal material, enhancing overall production efficiency.

Flexibility: It is adaptable to different materials and production requirements, exhibiting strong production adaptability.

Automation Control: Advanced collection roll devices are often equipped with automated control systems, allowing for precise adjustments of coiling parameters.

Space-saving Design: Typically designed to occupy a relatively small footprint, suitable for hot rolling production lines with limited space.

4. Maintenance and Safety:

Regular Inspection: To ensure normal operation, regular inspections and maintenance are necessary, including adjustments to straightening rolls, lubrication, and checks on the drive system.

Safety Measures: The device is usually equipped with safety features such as emergency stop buttons and protective covers to ensure the safety of operators.

In summary, the collection roll device is a critical auxiliary equipment in the hot rolling mill, providing essential functions for straightening and coiling metal materials produced through hot rolling.
