Hot rolled sheets/plates unpickled or pickled. The quality of the sheets/plates is developped especially for plasma- or lasercutting and also for optimal stamping or bending. LaserpressPlus® is available in different "Steel grades".


Advantages

LaserpressPlus
Advantages for laser and plasma cutting :
- Faster Cutting: up to 30% more productivity due to a lower Silicon content and minimisid surface scale.
- Perfect flatness.
- Limited deformation of the cut piece.
- Minimised burr on the cutting side.


Advantages for automatic bending, stamping and punching:
- Excellent cold transformation due to a higher yield point.
- Flatness tolerance = maximum 3mm/m.
- Refined metallurgy with narrow tolerances: exact bending and perfect reproduction piece after piece.

To be able to enjoy modern technology in steel processing, it is necessary to use sheets adjusted to the most up-to-date technologies. Sheets ought to be free of stress, have a superior degree of flatness and should be better to handle when cold transforming compared to the classic plate.
To answer all these questions Van Heyghen Staal NV has developed a new quality: LaserpressPlus®. Its fine grained structure, high yield point and a guaranteed flatness tolerance of 3mm/m ensure that this quality can answer to the harshest quality requests. A productivity gain of 30% is quite common when you use LaserpressPlus®.
This exceptional result is achieved by our exclusive in line Skin-Pass. This Skin-Pass eliminates all internal stress, improves shape, provides greater thickness control and produces a more desirable surface finish.
Our exclusive in line Skin-Pass continuously corrects the shape of hot rolled sheet and plate, combining continuous cold reduction with corrective levelling equipment. Producing this way, we can guarantee a constant and measured elongation of the full thickness of the sheet/plate.
This unique way of producing ensures a unchallengeable supreme result!
LaserpressPlus® exists in various steel grades of hot rolled steel, pickled or unpickled, with trimmed edges or mill edges.

LaserpressPlus® is obtained in three stages


1. A modern metallurgy with narrow tolerances :

2. A better precision when processing:

- Thanks to a perfect temperature control during hot rolling , LaserpressPlus® sheets are stress free.
- LaserpressPlus® sheets also have a more narrower thickness tolerance than standard sheets.

3. Removal of residual stresses by combining Temper Mill guaranteed elongation and corrective levelling. Our exclusive Temper Mill in line improves shape , provides greater thickness control , produces a more desirable surface finish and eliminates internal stress memories of hot rolled sheet and plate.

Our machines are specially designed to guarantee following flatness tolerances:
