Process

From scrap to high-grade steel

Steel production at Swiss Steel is the beginning of a valuable recycling process, and therefore also under ecological aspects an important factor of our economy and society.

Iron scrap of good quality - mainly of Swiss origin - is melted in our 80 tons electric arc furnace.

The secondary metallurgical processes pass off in the ladle furnace:

• Alloy and micro-alloy of the cast
• Temperature adjustment

 
After treatment in the ladle furnace, for particularly high-quality demanding steel goods there follows a secondary metallographic treatment in the vacuum machine. This treatment reduces the oxygen and nitrogen content of the steel through powerful rinsing in a vacuum. 
  
As a next step the 11 m steel billets of 150 mm square are produced by continuous casting machine, forming the billets from which the steel is rolled into bars or wire rod.

The entire production process is liable to an effective quality assurance, either by technological processes, or by continuous testing
