Descalers

Descalers are used on drawing, cold rolling and stretching machines to remove the calamine formed during the hot rolling process and the oxide from the wire surface caused by a prolongated exposition of the material with the air and humidity.

Descalers are designed and tailored according to the customer target requirements in terms of cleanness and specific installation layout of the machines and customer company.

Our range of mechanical descalers includes:

• Vertical descaler machine
• Horizontal descaler machine

The vertical and horizontal descaler cleans the rod surface by eliminating the scale that is the surface oxide coating by means of alternate bending of the wire rod during its passage through different rolls positioned on different planes.

They are composed of a rigid base and support, manufactured in steel on which are installed several rolls with anti-wear tungsten carbide insert long life use. They are totally closed, and the scale can be collected through a container present in the lower part of the descaler.

The vertical type is used for wire rod up to a diameter of 8 mm and the position of al the rolls is fixed.

The horizontal model allows the entry of wire rod up to a diameter of 20 mm and the degree of descaling, is given to the ability of two (2) adjustable rolls to penetrate the wire. The position of the adjustable rolls can be regulated directly from the operator control pulpit thanks to the use of motorized screw-jack (an electrical sensor permits to record and recall by recipe the position of the rolls, setting them automatically).

Both these devices are indicated to remove the heavy calamine before cold rolling, drawing or stretching operation or to works in combination with successive cleaning wire systems to reach a deeper cleaning degree.
