United States Steel Corp. will invest more than $1 billion to construct a sustainable endless casting and rolling facility at its Edgar Thomson Plant in Braddock, Pa., and a cogeneration facility at its Clairton Plant in Clairton, Pa., both part of the company’s Mon Valley Works. The endless casting and rolling technology combines thin-slab casting and hot-rolled band production into one continuous process and will make Mon Valley Works the first facility of this type in the U.S., according to the company.

The installation of endless casting and rolling technology will improve the quality and attributes of U.S. Steel’s downstream products for customers in industrial and construction markets. With this investment, Mon Valley Works will become the principal source of substrate for the production of the company’s XG3 advanced high-strength steel (AHSS), which assists automotive customers in meeting fuel-efficiency standards. First coil production is expected in 2022.

The new endless casting and rolling facility will replace the existing traditional slab caster and hot-strip mill facilities at Mon Valley Works. Current and future employees will enhance their skills with more advanced manufacturing to operate and maintain the facility through training programs developed in partnership with local universities.

As part of this project, U. S. Steel will also build a new cogeneration facility, equipped with state-of-the-art emissions control systems at its Clairton Plant, to convert a portion of the coke-oven gas generated at its Clairton Plant into electricity to power the steelmaking and finishing facilities throughout Mon Valley Works.
