Tenaris takes another step towards cleaner steel production in Argentina

Tenaris’s integrated seamless pipe mill in Campana, Argentina, will install a new Electric Arc Furnace (EAF) equipped with Tenova’s Consteel® technology. The investment will reduce CO2 emissions, generating greater energy efficiency while increasing production.

The new Consteel® EAF will replace one of the two existing EAF units at the mill and will by itself have the same productivity as the two existing EAFs combined. It will have a production capacity of 950,000 tons of liquid steel for seamless pipe manufacturing.

Tenova’s Consteel® technology uses a continuous feed of raw materials instead of a batch process. Raw feed materials are heated and charged continuously into the EAF and melted by immersion in the liquid steel present in the furnace, while simultaneously controlling gaseous emissions.  This increases energy efficiency and productivity of the steel shop as well as offering much improved emissions control.

In addition to the Consteel® EAF, Tenova’s scope of work also includes Consteerrer® technology. Developed in partnership with ABB, this innovative electro-magnetic stirring system significantly lowers operating costs, while offering reliable operations and superior quality steel. Tenova will also provide engineering services for the project.  

“At Tenaris, we are transforming our production process to meet new requirements for cleaner steel. The Consteel® furnace is part of a series of investment projects that will allow us not only to continue increasing production capacity in our steel shop, but also to reduce CO2 emission intensity of our steel process. Together, with the use of renewable electricity from the wind farm we are building in Argentina, it will result in a significant reduction of our carbon footprint, in line with our 2030 decarbonization goal," said Javier Martínez Álvarez, Tenaris President for Southern Cone.
