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.
Most of our pusher furnaces designed between twenty and thirty years ago are still in operation today and provide quality products. Tenova pioneered the use of hot riders for skids in these applications and developed the technology for almost 30 years. Today, we offer an innovative modular pusher furnace design for cost effective installations.
In addition to complete installations, we provide advanced modifications and solutions to enhance pusher furnaces including:
- New skid systems
- Off-set of the skids
- New hot rider designs
- Burners with low NOx emissions
- Waste heat recovery systems
Tenova has provided revamp projects for productivity increases (up to 30%), optimum temperature uniformity, increased surface quality and improved energy efficiency.
We have pusher furnace references for various types of products such as:
Intermediate products/pre-shaped blanks

Reheating Furnaces for Flat Products
Roller Hearth Furnaces for Thin SlabTenova 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 ProductsTenova 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.
Walking Hearth Furnaces for Flat ProductsWalking 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.
