Italian plant builder Tenova, has successfully started up two 400 tonnes/hr walking beam furnaces at Ternium’s new hot strip mill facility in Pesqueria, Mexico.

Ternium, a leading steel manufacturer in the Americas, produces and processes a wide range of steel products.

According to Tenova, the advanced features of its two state-of-the-art WBFs provide Ternium with reduced emissions and energy savings. The furnaces are designed to heat steel slabs (up to 39 tonnes) at 1,250°C, with a specific consumption of 1.16 MJ/kg, while keeping NOx emissions lower than 60 ppm.

“The Ternium Industrial Centre started its first phase in 2013 focused on downstream products such as cold rolled and galvanized for the industrial market. Now, we have started up the main production line of the 2nd phase, a new hot rolling mill with a capacity of 4.4 million tons. The two new WBFs are part of the plant’s new lines and will produce coils to be used in the automotive market in the USMCA area, granting Ternium an increased access in this sector”.

Paulo Lopez, Pesquería plant director at Ternium.

Both furnaces incorporate Tenova’s SmartBurner Monitoring System (SBMS), which, it is claimed, enables the monitoring and optimizing of burner performance, operation and maintenance. Tenova says that the SBMS is a network of embedded sensors connected to Tenova’s digital infrastructure, through secure connection protocols and intrinsic system reliability. The collected data is post-processed locally on an edge computing unit as well as remotely on the Tenova Cloud. By constantly monitoring the status of the burner, the SBMS is claimed to offer breakthrough approaches to inspection, maintenance and tuning, as well as reducing safety risks related to on-site operations.

Walking beam furnaces from Tenova are not new to Ternium. The steelmaker has installed them at its plants in San Nicolas in Argentina and in Monterrey, Mexico.
