Walking Hearth Furnaces for Flat Products
Walking hearth reheating furnaces are highly flexible solutions featuring some key advantages such as: low scale production, low decarburization and no product remains in the furnace when the furnace has to stop operation (ability to walk final product piece through).
The Tenova walking hearth furnace design produces a high quality final product due to the lack of mechanical marking. Our proven wheels, ramps and guide systems provide reliable furnace operation. Long refractory life, minimized deflection and convenient scale collection are the advantages of our hearth design.
Applications include the reheating of:
- billets
- blooms
- slabs
- beam blanks
- pipes
Tenova Walking Hearth Furnaces for Long Products (Billets, Blooms and Beam Blanks), as all its reheating furnaces, are engineered to achieve top performances in all conditions while strongly limiting the pollutant emissions. This results is possible following the breakthrough improvements applied in the recent years by Tenova to the combustion system and to the process control technology.
Value for Money
- Reduced OPEX due to the strong energy saving
- Reduced maintenance activities
- Due to its design it is possible to charge even very short slabs eventually on multiple independent rows thus optimizing handling operations.
Efficiency
- Strong energy saving due to the ultimate combustion technology
- Optimized process control
Safety
- No budget limitation for safety issues
Service
- Engineering services for upgrades of existing equipment
- Turnkey solutions and installations of integrated systems

Reheating Furnaces for Flat Products
Pusher Type Furnaces for Flat Products
Modern design techniques and solutions adopted for new furnaces can give fresh life to old plants. New offset skid systems, new hot rider designs, burners with low NOx emissions are some of the advances applied to older furnaces to boost production capacity, improve temperature uniformity, enhance surface quality and save energy.
Roller Hearth Furnaces for Thin Slab
Tenova roller hearth furnaces implementing latest-generation direct rolling technology are suitable for slab lengths of 30-50 m and, in special cases, for endless rolling of bar lengths up to 300 m. Typical thickness ranges between 40 to 90 mm. With a constant focus on critical components such as rollers and burners, Tenova designs outstanding roller hearth furnaces. Milestones include the longest furnace, the furnace with the highest temperature and the first operating furnace with three lines.
Walking Beam Furnaces for Flat Products
Tenova has installed some of the world’s largest walking beam reheating furnaces for a variety of applications. Our walking beam furnace design combines the latest advancements in hot rider and skid system technology, process control and Level 2 automation as well as advanced burner technology.
