Finishing 4 high rolling mill for strips and plates

The strengths of the QR48 rolling mill are::

  • il the fast change of work cylinders, which can be replaced by hand in just 15 minutes, without using particular equipment;
  • the four high configuration, also used in the QR65 mono-stand rolling mill.

This model also includes: :

  • the possibility of carrying out operations on reduced lengths or on rolls using the reversible mode;
  • customized spoolers inbound and outbound for work on rolls or rollers for straight bars;
  • two options to carry out vertical adjustment (assisted manual handwheel or brushless motor and high precision encoder)

  • multi-metallic materials
  • special alloys and superalloys

QUARTO rolling mills configuration

Four high configuration includes insertion of two large support cylinders to support the two work cylinders of small diameter, necessary to:

  • reduce separation force during rolling;
  • reduce deformation energy;
  • guarantee a constant end thickness;
  • reach reduced minimum thicknesses;

The work cylinders are also cooled to make the result even more precise.

Advantages

Over 55 years of business has allowed INVIMEC to design and create mono-stand rolling mills with endless strengths:

  • the strong and rigid design guarantees extreme precision and consistency of the final measurement;
  • the machine is extremely intuitive, thanks to the ample HMI display and the multiple manual commands that simplify use in manual and automatic mode;
  • the operator is completely safe, while at the same time maintaining maximum accessibility and easy inspection:
