Reheating furnaces

Profitable, sustainable heating How to slash your energy consumption.

Today, reducing pollutants such as NOx is a key priority in combustion technology. Regulations on CO2 emissions trading as well as ultra-low NOx requirements demand greater investment in green technologies. So, pivotal in cutting fuel consumption is a prime focus on efficient state-of-the-art furnace design. Not only good for the environment, this also generates immediate financial benefits for you.


Walking-beam furnaces

High productivity and flexibility

Top and bottom-fired walking-beam furnaces ensure high production rates and excellent quality steel grades. They handle billets, heavy blooms, slabs, and beam blanks. Included here are a number of cooled elements as well as special alloy parts that withstand high temperatures and mechanical stresses. Furthermore, due to the sophisticated combustion system, all our walking-beam furnaces are highly flexible.

Our high-tech machines prevent misalignment in the discharging area, even coping with workpieces of very different sizes and shapes. They virtually eliminate vibrations and positioning errors. Plus there are further key advantages such as reverse movement in emergency situations as well as the option of manual handling. You can choose from a wide range of kick-in and kick-off machines, operated both electro- mechanically and hydraulically - so you meet even the most challenging demands.

Typical data

Billet size range: > 120 mm: blooms slabs or beam blanks
Production range: > 100 t/h
Specific consumption: ≤ 280kcal/kg

Walking-hearth furnaces

Lower consumption figures

Walking-hearth furnaces are the perfect choice for many long product mills, with production rates of up to 140 tons per hour.

Operating with top heating alone means they are ideal for products with a maximum thickness of 160 mm. It also benefits you that this furnace type significantly cuts specific consumption because there are no water- cooled elements inside the furnace.

Typical data

Billet size range: ≤ 160mm
Production range: 60 to 120 t/h
Specific consumption: ≤ 260kcal/kg

Pusher furnaces

Low investment costs, robust design

Have you ever thought about heavy-duty, no-frills furnaces for billet reheating? Then a pusher furnace is a smart choice. Why? Because this type is designed specifically to operate in low-production-rate mills for common steel grades such as rebars.

Highly adaptable

Top-fired pusher-type furnaces combine the benefits of sturdy construction and simplicity in design with low consumption rates. Common to both top and bottom- fired pusher-type furnaces is the fact that they attain high production rates. So, if you produce simple products, pusher-type furnaces are an inexpensive alternative to more sophisticated walking-hearth or walking-beam types.

Better combustion for customized steel quality and less fuel consumption

Now available is SMS PROMETHEUS®, a great way to enhance your furnace's overall performance. This advanced combustion optimization system improves the parameters that make a difference in the production of special steel qualities. That's because SMS PROMETHEUS® systematically refines metallurgical properties such as increased temperature uniformity, and suppresses negative effects including steel decarburization or scale formation.
