From scrap to high-grade steel
Steel production at Swiss Steel is the beginning of a valuable recycling process, and therefore also an important factor of our economy and society from an ecological aspect.
Iron scrap of good quality - mainly of Swiss origin - is melted in our 80-ton electric arc furnace.
The secondary metallurgical processes are conducted in the ladle furnace:
- Alloy and micro-alloying of the heat
- Temperature adjustment
For particulary demanding steel grades, a further secondary refining treatment in the vacuumdegassing unit follows the treatment in the ladle furnace This treatment reduces the oxygen and nitrogen content of the steel through purging in vacuum.
The continuous casting machine then produces the 11 m steel billets of 150 mm square, from which the steel is rolled into bars or wire rod, tested, and finished.
