Inline Pre-Treatment System Solution

Description

The wire rod is subsequently propelled by a horizontal wire rod pay-off system in a combined pull-in, bending and straightening machine (BDM-2S / EG). The scale layer is broken and the wire is straightened without cracks. The wire pull in is considerably facilitated by this system concept.

In the following double-head sanding descaler (SEZ-6-302S), the wire will be cleaned and surface pre-treated for the further coating process through two sanding belts with min. 98% cleanliness result.

The next wire preparation step is done by an electro-phosphating plant (Ephos®) Inline from STAKU.

Production range:

Wire inlet ø8.0 – 15.0mm
Wire outlet drawing speed up to 10m/s
Wire inlet speed up to 1.5m/s

For Example:

Wire inlet ø13.0mm
Finished wire ø5.0mm
Wire inlet speed 1.2m/s
Wire outlet drawing speed 8m/s

Mechanical descaling with inline phosphating at the same drawing speeds as conventionally pickled wires without sacrificing quality.

Technical Specifications

Advantages of this electrolytic process compared to classical chemical phosphating

Bath temperature only 45 ° C instead of 80 ° C
Sludge-free process
33% less zinc by replacement with calcium
40% lower chemical requirements due to compact and fine crystalline layer
3 seconds coating time compared to 7 minutes for classic procedures
Elimination of highly toxic activation chemicals
High binding forces prevent shearing during forming
No waste of old acid, use of economy flushing technology reduces wastewater by 40%
No after-treatment with soaps, lime or similar
