A new automatic cold cutting and stacking area has been installed at METALLURGICA MARCORA S.p.A

A new automatic cold cutting and stacking area has been installed at METALLURGICA MARCORA S.p.A., in order to allow for:

-      Increased productivity

-      Fully automatic operation

-      Possibility to have buffers along the area in order not to stop production in case of any downstream delay

-      Possibility to handle the bar layer within the min cooling bed cycle

-      Automatic removal of tails and sample collection at cold shear

-      Automatic removal of short bars

-      Perfect square stack shape

-      In line automatic strapping and weighing

Scope of supply of NCO was including the complete dismantling of the old equipment and the installation of the new machines:

• New bar layer formation chain transfer and translating trolleys at cooling bed exit;
• New cold shear 300 t capacity, “C” shaped, in order to allow its installation in front of the cooling bed and therefore allowing for increased max commercial bar length within the available space;
• New motorized movable gauge, cantilever type, ensuring max visibility of the area and easy access for maintenance, and equipped with servo-motors in order to allow for stricter cutting tolerances and positioning for the different bar lenghts even at rollers area.
• New bar layer preparation area at stacker entrance, operating into two sections and including an automatic bars aligning roller table and short bars extraction and rejection system;
• New automatic non-magnetic stacker fully electrically controlled via brush-less type motors, ensuring:
  • highest speed movements
  • maximum positioning precision
  • cycle repeatibility
  • possibility of adjusting acceleration and deceleration ramps depending on the finished product size
  • maintenance-free operation.
• In-line automatic strapping, weighing and storing area;
• Hydraulic and Lubrication systems.

Interconnecting piping, fully pre-fabricated off-line in order to minimize the plant shut-down time.

Metallurgica Marcora and NCO are glad to maintain and revive their successful and lasting cooperation in the business of steel making.
