Manufacturing process
TYCSA PSC manufactures high-strength wires and strands by cold deformation (drawing) using high-carbon wire rod as raw material, which is transformed in the different stages of the production process.
Our process is developed through the following milestones:
1. Wire rod pickling
It consists of two main processes:
- Cleaning and preparation of the wire rod surface for subsequent drawing. The process begins with the wire rod passing through the automatic pickling line. This line chemically cleans the iron oxide (Fe₂O₃) accumulated on the surface, as well as the scale formed during hot rolling. This process is carried out using chemical or mechanical attacks and is followed by cleaning with water.
- Preparation of the wire rod surface for subsequent drawing. Coating the steel surface with products that reduce friction during drawing and improve corrosion resistance.
2. Cold drawing
A process that involves drawing wire rod through a series of dies to achieve the appropriate physical strength and ductility characteristics to meet our customers’ needs.
As a result of the mechanical treatment, which involves a constant and uniform reduction in cross-section, the material hardens, resulting in a smooth product surface.
The maximum tensile load reaches values between 1,600 and 2,300 N/mm².
3. Stabilized
The stabilization treatment of wires and strands consists of a stress-relieving operation achieved by heating the resulting product after the wire drawing process and simultaneously subjecting it to mechanical stress. Finally, it is cooled along the way, using water at a controlled temperature.
Upon leaving the cooling section, the cord is air dried to prevent it from reaching the folding reel when wet.
