Celsa Barcelona has contracted SMS group to revamp the section mill at its Castellbisbal location in Spain.

Since 2000, Celso Barcelona has been producing I and H beams on a medium-section mill supplied by SMS group. The mill was originally designed for an annual production of 500.000 tons.
The German supplier first expanded the initial range of products rollable on the mill during a revamp in 2007. According to the company, continuous plant optimization has raised the mill’s annual capacity to 1 million tons since then.

The recent contract for SMS group now covers the replacement of the existing cooling bed with a new, higher-capacity one and the upgrade of the CRS (Compact Roller Straightener), making it capable of straightening heavier products. These measures will require adjustments to and upgrades of the existing electrical and automation systems, all of which will be performed by SMS group.

The new cooling bed will come with an aerosol cooling system that will boost the cooling efficiency and, consequently, the mill’s productivity. Another special feature of the new cooling bed will be a turning device designed to turn I and H beams through 90 degrees into or out of the upright position. This device will further increase the through-put rate of these products. The planned revamp will enable Celsa Barcelona to add HEA y HEB de 600 to its portfolio and further enhance its production efficiency.

The work on the straightening machine is planned to be performed during the 2020 summer break. The new cooling bed is to be installed and commissioned during the 2021 summer break.
