Advanced Four-High Reversible Design

With its 4 Hi reversible stand configuration, this used cold rolling mill offers enhanced strip flatness and superior thickness reduction. The five stands facilitate consistent processing, while reversibility allows bi-directional rolling, optimizing production efficiency for diverse steel coils. This flexibility enhances the mill's suitability for a range of industrial cold rolling requirements.

Efficient Cooling and Drive Mechanism

The integrated water spray cooling system ensures effective temperature control during operation, promoting high-quality surface finishes and extending roller lifespan. Advanced AC motor drive delivers reliable power and precision to accommodate demanding rolling speeds of up to 600 meters per minute, supporting the mill's substantial hourly capacity and production needs.

FAQ's of 1450 Used Cold Rolling Mill:

Q: How is the strip thickness adjusted during the cold rolling process?

A: Strip thickness is regulated by the 4 Hi reversible mill's hydraulic system and PLC-based controls, which enable precise settings for the roller gap during each pass. Operators can manually or semi-automatically select the desired thickness, ensuring output within the range of 0.2 mm to 2.5 mm.

Q: What materials can be processed with the 1450 Used Cold Rolling Mill?

A: This mill is suitable for mild steel coils, allowing efficient reduction of input sheet thicknesses up to 4 mm into rolled strips of 0.2-2.5 mm thickness. Its robust design ensures consistent processing and surface quality for steel coil applications.

Q: Where can this rolling mill be installed and operated?

A: The mill is designed for installation in steel processing facilities, manufacturing plants, or coil service centers. Its versatility and moderate space requirements (42 meters line length) make it a practical choice for various industrial settings, particularly those focused on cold rolling operations.

Q: What are the operational benefits of the water spray cooling system?

A: The water spray cooling system efficiently removes heat generated during high-speed rolling. This maintains optimal roller and strip temperatures, resulting in improved surface finish, reduced risk of thermal damage, and enhanced mill component longevity.
