• Features and advantages

Rolling Capabilities:

• Can process lead and lead alloy coils with a thickness range of 1.2mm to 6mm and a width range of 550mm to 1400mm.
• Produces cold rolled lead and lead alloy coils with a final thickness as low as 0.15mm.
• Capable of rolling speeds up to 150m/min.

Mill Configuration:

• 2-high reversible mill configuration with work rolls and backup rolls. 
• Work rolls can be adjusted for positive and negative bending to control strip shape. 
• Backup rolls provide support and rigidity to the work rolls during the rolling process. 

Automation and Control:

• Utilizes a programmable logic controller (PLC) for automated control of the rolling process. 
• Includes features like automatic roll gap adjustment, roll force control, and thickness measurement. 
• Operator interface with HMI (Human-Machine Interface) for monitoring and adjusting the rolling parameters. 

Specialized Design:

• The mill is specifically designed for lead and lead alloy materials, which have unique properties compared to other metals. 
• The rolling mill components are made of materials suitable for handling lead, such as special alloy steels, to ensure long service life. 
• Comprehensive safety features are incorporated to protect operators and the equipment during lead processing.

• Technical parameters

Note: The above specifications are for reference only. Customized cold rolling mill as per customer's requirements and demands would be available.

• Process flow:

• Packaging & Shipping

Packaging:

All parts of the Ø550×1400mm 2-Hi Reversible Cold Rolling Mill are fixed inside container by steel wires and special PET straps, in order to make sure all parts will not move during transportation and avoid any kinds of damage of machine and container.

Shipping:

Sea Freight: The Ø550×1400mm 2-Hi Reversible Cold Rolling Mill is often shipped via ocean freight, especially for international transportation. The equipment is securely loaded into shipping containers or flat racks, which are then loaded onto cargo vessels. This mode is suitable for long-distance shipping and can accommodate larger and heavier cold rolling mill.

Air Freight: When there is a need for fast delivery or for shipping smaller or lighter cold rolling mill, air freight can be used. The equipment is packed and loaded onto aircraft for transportation. Air freight is typically more expensive than ocean freight but offers quicker transit times.
