Widest CSP® plant worldwide

A new, consumption-optimized CSP® furnace and a plant wider than ever before: The CSP® plant of Big River Steel is setting new standards worldwide and is characterized by lower energy losses and very low emission levels.

With a finished strip width of 1,930 millimeters the CSP® plant of Big River Steel is the world’s widest of all CSP® plants. And not only that: SMS group implemented also a number of technological innovations in the 29th CSP® plant and attained optimum performances which impressively demonstrate the efficiency of CSP® technology. The CSP® plant consists of a CSP® continuous casting plant of the VSB (Vertical Solid Bending) type, the CSP® tunnel furnace, the six-stand CSP® rolling mill, the laminar cooling system and a downcoiler.

The first strip was produced on the CSP® plant on December 10, 2016. In January 2017, the first full production month, 57,000 metric tons (approx. 63,000 American short tons) left the plant – world record for all CSP® plants. At the beginning of November 2017, Big River Steel broke the mark of one million tons produced on the CSP® plant. Another outstanding achievement is also an extremely low cobble rate. Here, the figure for example in July and August 2017 was below 0.06 percent.
