120 strips at a time and high-speed trimming operation

Modern slitting lines aim at processing heavier and wider coils to decrease coil-to-coil time, and thus optimize output. To follow this trend, an increased number of cuts -already guaranteed for up to 120 cuts, together with excellent and repeatable finished product characteristics- is made possible by implementing CNC slitting shear technology.
Lower investment costs due to elimination of pre-cutting systems can be reached through automatic coil and spool handling, hydraulic clamping of recoiler mandrels and a 50% reduction of slitting-tool changing time. Line speeds up to 1500 mpm already have been realized.

Super Slitter

Continuous operation and large strip length call for the best possible -and repeatablecutting results. Great value is attached not only to the strip-width tolerances, but also the strip-edge quality (burr) over the complete strip length. The Super Slitter is the right answer to these requirements, already tested in several applications for both ferrous and non-ferrous applications. Through a reduced bearing distance and an optimized whole bearing system, the new slitting head features a 44% deflection reduction and a knife-shaft rigidity that’s increased by more than 130% compared to conventional systems.

ECB system for touchless braking of sensitive material

A rotating magnet system (Eddy Current Brake) can apply an adjustable tension to the non-ferrous metal strip with no need for any additional braking devices. Braking force can be adjusted and controlled according to actual working conditions in a closed-loop mode. The unit is of compact design and can easily be implemented in existing lines.
Smooth braking is especially suitable for surface-sensitive strip such as high-gloss or tinned material. Optimum strip thickness ranges from about 0.2 mm and thicker.

Narrow 20-high cold rolling mills

10 μm “thickness” at a copper cold rolling mill, with max speed of 600 mpm will be rolled on one of the latest 20-high mills supplied. The design of these cluster mills combines various adjustment and control mechanisms that have different effects, such as tilting of the top rolls, hydraulic bending of outer and inner intermediate rolls, or shifting of inner intermediate rolls.
The roll gap contour can be rapidly adjusted to the changing profile of the entering strip. The design is especially suitable for narrow applications where pre-slit strip having a wedged shape will be rolled to a perfectly shaped finished material.

Melting and continuous casting

Horizontal conticasting of NF metals requires a high quality melt that can be reached through electric channel-type induction furnaces with proper operating practices and control of raw materials. Continuous casting is achieved by pulling solidified strands with a special pre-programmed withdrawal machine. The solidification occurs inside graphite dies that are effectively
water-cooled. This enables casting speeds of up to 600 mmpm and, therefore, also small and uniform grain structure that is very beneficial for further processing. To meet the high capacity of the horizontal conticasters, melting furnaces can reach a capacity of 6 tph each.

Chain track drawing

Chain track continuous drawing is the latest and patented innovation in high-speed drawing -up to 600 mpm- of tubes and solid profiles. Thanks to the electronically controlled hydraulic pressure closing system, the pressure applied by the pulling jaws onto the material is optimized, avoiding slippage and ensuring good surface quality. For finishing lines, the pulling jaws with quick couplings can be replaced easily in less than 10 minutes. The sturdy machine design reduces maintenance requirements.
The chain track machines can be arranged in cascade, and they are available in sizes from 1 up to 26 tons of pull power.

ECT Endless Copper Tube

This innovative process applies continuous casting of hollow shells to high output rolling in a 4-roll planetary mill. Then the rolled mother tube coils are breakdown drawn in highspeed chain track drawing machines arranged in cascade, followed by conventional drawing into finished dimensions. With this automated, compact and easy-to-operate process, tube coils heavier than 1 ton can be handled. The process benefits are high capacity (up to 70,000 tpy), high yield and excellent eccentricity,
enabling a profitable world-class quality copper tube production, including the most demanding thin wall ACR-tubes.

Front loading extrusion presses

Front loading sytem is the innovative solution that reduces idle times during the extrusion cycle and, at the same time, makes possible a remarkable improvement of the final product quality. Danieli front loading charging system allows to load the billet into the front side of the press, between the container and the die, giving absolute accuracy in centering the billet position along the centerline of the press. The speed of execution, the accuracy of positioning, and the extremely variable billet length possibility are the points of excellence of our system.
