Brushes for Rolling Mills and Coils Treatment | Mechanical Pickling of Steel and Aluminium

Line Steel of Roller Brushes for the industry of Rolling Mills and of pickling by SIT Tecnospazzole

In the Rolling Mills and in Coils Treatment in iron, with filaments, aluminium and alloys you may need some Pickling or Superficial Treatment, and for this it is necessary to have brushing groups mounting Technical/Special Cylindrical Brushes suitable for this goal.

Line of Rolling Mills summarized. The SIT brushes are used in the phases of removal, finishing and polishing

Type of Brushes - Building Techniques

Spiral brushes with high density of filaments mounted on with high density cavo a Tube

Technical Brushes for Rolling Mills and pickling can be mounted on cores a Tube empty or "filled" with hubs. Cores can be mono-use or reusable.

Spiral brushes with high density of filaments mounted on a full metal core with hubs for mounting

SIT Tecnospazzole offers to its customers the service of returning the brush worn out to reuse the core. This way the customer has an economical saving and a lower environmental impact.

The interchangeable SIT Brushes for pickling and in general the large size ring or spiral brushes are mounted on the core with hubs e locking sleeves that allow for a rapid replacement of the brush. Every item is designed and built in accordance with the needs of mounting and processing of the customer.

Materials, types of Surfaces and Filaments

The surface treated can be of type ferrous (carbon and with filaments) and non ferrous (aluminium and special alloys). Depending on the type of finishing required, you may choose a filament with rectangular or elliptic or circular section.

How it's Made: Trimming and Balancing

A special trimming allows to obtain a perfect cylindricity of the brush with reference to the rotation axis. As a result all the surface of the brush works equally and uniformly on all the surface of processed sheet.
All the brushes are balanced dynamically ISO 1940 g. 6,3 and accompanied by the relative certificate.
