  • The most advanced mathematical model of X-Pact® Prometheus

Furnace types

  • Pusher type furnace

    Affordable investment combined with robust design

    Main data

    Pusher furnaces are typically suitable for low-production mills for common steel grades, for example rebar mills. Top-fired pusher type furnaces combine the benefits of a sturdy construction and simplicity in design with low consumption. Top and bottom-fired pusher type furnaces are capable of high production rates. Pusher type furnaces are an inexpensive, yet sturdy and reliable, alternative to more sophisticated walking hearth furnaces or walking beam furnaces for the production of long and flat products.

  • Walking beam furnace

    High productivity combined with operational flexibility

    Main data

    SMS group walking beam furnaces, both top and bottom-fired, allow for high production rates and top quality steel grades. Billets, heavy blooms, slabs and beam blanks can be processed. Walking beam furnaces feature special skid beams with cast alloy parts which endure high temperatures and mechanical stresses. SMS group continuously works on the development and integration of new designs and materials. Thanks to the advanced combustion system, all SMS walking beam furnaces are highly flexible in operation.

  • Walking hearth furnace

    High production rates at minimum specific consumption figures

    Main data

    Walking hearth furnaces are the optimum choice for many long products mills with production rates of up to 150 tons per hour. A major advantage of this furnace type is that it allows for very low specific consumption figures, achieved thanks to the absence of water-cooled elements inside the furnace.

  • Rotary hearth furnace

    Reheating and heat treatment for seamless tube production

    Main data

    We believe in holistic solutions as the key to quality leadership. That’s why we combine our seamless tube mill with high-end furnaces. Both, rotary hearth furnaces and shell reheating furnaces, are fully integrated into the rolling process. They combine high capacities with special materials and components for maximum temperature endurance to withstand the high temperatures typical of this process – in order to reduce your maintenance costs.

    High-tech combustion systems guarantee temperature uniformity and minimum energy consumption.
