For more than 50 years, Novelis PAE has built up unique expertise in the field of continuous strip casting. With over 120 Jumbo 3C-3CM® twin-roll casters in operation worldwide, we are recognized as the leader in this technology and are proud to offer our customers a wide range of production capabilities in terms of strip width, alloy composition and end-product applications.
Principle: The Jumbo 3CM®, the latest generation of Novelis PAE continuous casters, produces strips of aluminium alloys by feeding molten metal between water-cooled rolls on a 2-hi mill. The process combines metal solidification and hot rolling in a single step.
|BENEFITS OF CONTINUOUS STRIP CASTING VS HOT ROLLING|
|On-site scrap processing
All scrap can be recycled into value-added products.
|Modular investment and flexible operation
Production capacity can be progressively increased to keep pace with market demand.
|Low capital and operating costs
A continuous caster performs an all-in-one process that replaces DC casting, scalping, sawing, preheating and hot rolling. This short process reduces capital and conversion costs, including manning and energy.
As a single-step process, continuous casting produces strips from molten metal in a shorter time compared with conventional processing routes. This enables a rapid response to customer demand and reduces inventory

The control of metal feeding in terms of metal level, flow and temperature distribution throughout the width of the strip is critical to guaranteeing the required strip gauge and profile quality.
Novelis PAE has designed a metal feeding system that enables the operator, during the casting process, to adjust the flow of metal in the tundish before it enters the tip.
The tip position can be adjusted with precision in every direction thanks to the tip table mounted on the floor. An appropriate gap is maintained between the tip lips and the rolls to avoid any touching.
