Descaling in copper production
Descaling in copper production with HERMETIK technology
Descaling in copper production – inclusion-free non-ferrous metal processing with HERMETIK
Conventional descaling of copper semi-finished products is costly and, if carried out using pickling, has many disadvantages for the environment. Water milling descaling in copper production enables a production process without a pickling plant and is therefore significantly more environmentally friendly in comparison. This is where HERMETIK come into play.
In contrast to chemical descaling, a modern HERMETIK descaling system removes oxides (so-called scale) and impurities from the material surface using high-pressure water jets. All that remains is pure copper, free of oxides and inclusions. The oxidized copper particles can then be filtered out of the water at low cost. Highly efficient hermetic descaling enables future-oriented copper production without a pickling plant.
You too can take advantage of the efficiency-enhancing functionality of HERMETIK descaling for copper production and optimize production in your company. Get in touch – we will be happy to advise you.

HERMETIK Descaling in Copper Production at a Glance
Customized HERMETIK scale washers offer maximum efficient descaling in copper production for every company. Optimally adapted to your production process, HERMETIK descaling solutions offer significant time and cost savings as well as an environmentally friendly method of inclusion- and oxide-free copper semi-finished product production.
Descaling before rolling
Program-controlled HERMETIK rotors remove residues before the rolling process with pressures of over 1,000 bar. The process emulsion can be used here – for residue-free surface quality and efficient production.
Interstand descaling
Conventional stationary nozzle bars ensure residue-free surface quality between the roll stands. HERMETIK scale washers offer program-controlled adaptability to the product – this allows productivity to be optimized.
Descaling in the continuous production process
HERMETIK offers significant efficiency improvements in the production of copper wire for the electrical industry, among other things. A rail-guided water milling system as part of the hot strip line removes the scale from the entire surface of the copper strand using high pressure water.

HERMETIK TORNADO – ROTATING NOZZLES
Introducing: The HERMETIK patented rotating TORNADO nozzles for high pressure water milling. The nozzle for ultra-high impact force.
The HERMETIK rotating nozzles (patented) have a spiral movement pattern. They enable highly efficient descaling and remove scale from the entire surface, regardless of the type and composition of the scale.
THE TORSION TEST
The torsion test is a recognized quality control for coated and painted copper wires (15 turns in one direction)
After twisting the wire, the difference between rotor descaling and descaling without a rotor is visible. HERMETIK Rotor descaling removes the scale completely.

HERMETIK: Efficient descaling in copper production
When manufacturing copper wire, it is of the utmost importance that the product is free of oxides and production defects – thorough descaling in copper production is therefore an essential step. HERMETIK scale washers descale the copper surface in an environmentally friendly way using high-pressure water. Patented rotating nozzle heads, so-called descaling rotors, process the surface of the glowing copper strand and reliably remove all scale in the run-up to the rolling process. Instead of a costly and environmentally harmful pickling system, HERMETIK offers intelligently controlled water milling systems that erode scale and copper particles highly effectively and separate them from the water in a downstream filter system and recycle them.
With an ultra-high-performance scale washer system from HERMETIK, there are numerous advantages in descaling for copper production:
Perfect surface
Pure copper surface with hydropower.
Environmentally friendly
A HERMETIK system replaces the electrolysis plant.
Cost-efficient
With a HERMETIK oxide washer, no pickling plant is necessary. No second media circuit is required, the rolling medium is used for descaling. ROI < 18 months
Energy-saving
Significant energy savings compared to a conventional system. No significant temperature drop in the rolling process.
