Walking Hearth Furnace for Vinton Steel

Vinton Steel, headquartered in Vinton, Texas, has commissioned a new walking hearth reheating furnace. The furnace will be engineered for high-carbon steel billets used to manufacture large-diameter grinding media, a high demand product for the mining sector.

This addition is intended to operate alongside a new initiative to increase Vinton Steel’s rebar production capacity up to 400,000 tons per year. The initiative is called Green CityMill™ Flex, which represents an efficient and sustainable long products production platform.

Wieland Rolled Products North America was delivered the furnace by Tenova, which is integrated with a selective catalytic reduction (SCR) deNOx emissions control system. The equipment will enable Wieland to expand the production of high-grade copper products, essential for several key industrial sectors. This installation is a key element of Wieland’s broader investment to upgrade and expand its East Alton, Illinois facility.

“We are pleased to continue our collaboration with Tenova as we enter the next phases of this expansion project. Their technology and project management expertise are expected to support our production goals and sustainability efforts,” said Greg Keown, president of Wieland Rolling & Recycling.

Francesco Memoli remarked, “This project is particularly meaningful for us because it integrates advanced combustion and fume treatment technologies to meet both performance and environmental targets. It’s a clear example of how we tailor heat treatment solutions to the unique requirements of non-ferrous production.”

The furnace, engineered by Tenova Italimpianti, has a processing capacity of up to 110 metric tons per hour. Powered by a natural gas combustion system, it features Tenova’s proprietary TR Flat Flame Roof burners equipped with integrated recuperators and post-combustors. The configuration ensures a substantial 90% reduction in NOx emissions. This technology has already delivered positive environmental performance in both reheating and heat treatment applications.

Wieland’s expansion project includes a new hot rolling mill designed to increase production capacity for copper and copper alloy components used in electric vehicles (EVs), EV charging networks, and renewable energy systems.

Fringe Friday: Sustainable Long Steel Production in Texas

We’re celebrating getting to the “fringe” of the weekend with a Heat Treat Fringe Friday covering news about a Texas steelmaker making strides in sustainable metal heating with a new facility. An electric arc furnace and a technology platform are included in the company’s strategy to lower emissions and energy consumption and increase production.

While not exactly heat treat, “Fringe Friday” deals with interesting developments in one of our key markets: aerospace, automotive, medical, energy, or general manufacturing.


Vinton Steel LLC, the U.S. subsidiary of Kyoei Steel, is bolstering its steelmaking operations with a melt shop at its facility in El Paso, Texas, which includes an electric arc furnace (EAF) and an advanced technology platform designed to increase production capacity to 400,000 tons per year while significantly reducing emissions, energy consumption, and operational costs. This expansion is a major step in the company’s North American expansion.

Tenova, a developer and provider of sustainable solutions for the green transition of the metals industry, will supply the Green City Mill Flex platform, with construction expected to begin the summer of 2025 and plant startup scheduled for the first quarter of 2027.

“This project marks a significant milestone for Kyoei Steel Group’s expansion in North America,” said Masahiro Kitada, chairman of Vinton Steel LLC. “By investing in state-of-the-art green steelmaking technologies, we are not only strengthening our presence in the U.S. market but also contributing to the economic development of the local community and the entire West Texas region. We are proud to bring advanced and sustainable steel production to El Paso at the Border area, creating new opportunities for growth. We are happy to embrace our largest investment outside Japan with a long-lasting partner like Tenova.”

Tenova’s Green City Mill Flex is redefining the future of long steel production by setting new benchmarks in efficiency, product flexibility, and environmental responsibility. Engineered to manufacture a wide range of long steel grades with the lowest carbon footprint on the market, this innovative platform integrates cutting-edge technologies, including the third generation Consteel® Electric Arc Furnace technology. The plant will also feature continuous casting and rolling capabilities in collaboration with Pomini Long Rolling Mills. By leveraging the local steel scrap recycling supply chain, Green City Mill Flex strengthens the principles of circular economy and self-sufficiency, minimizing the environmental impact of steel production in urban settings.

“This project sets a new benchmark for regional steelmaking plants,” said Francesco Memoli, president and CEO of Tenova Inc. “The Green City Mill Flex platform represents the latest evolution of the mini-mill concept, adding unprecedented levels of flexibility, efficiency, and safety. It is a game-changer for long-steel producers looking to modernize and meet the demands of sustainable manufacturing.”

Under the contract, Tenova will supply a complete suite of next-generation technologies, including a 45-ton Consteel® EAF with continuous scrap preheating, an in-line ladle metallurgy furnace for precise steel refining, a multi-strand continuous casting machine, and a fully automated material handling system. The project will also include an advanced fume treatment plant with a quenching tower and pulse-jet baghouse, a zero-water-consumption water treatment plant, and a new electrical distribution system, all designed to maximize efficiency and sustainability.
