Refractory construction for Heat treatment – continuous

Continuous furnaces are the backbone of industrial heat treatment: walking beam furnaces, pusher furnaces, roller hearth furnaces, tunnel kilns and rotary hearth furnaces provide the continuous heating of slabs, billets, sheet and components. The refractory lining has to meet the highest demands in terms of temperature resistance, energy efficiency and mechanical load-bearing capacity.

SBS Refractory Service offers tailor-made refractory solutions for every type of continuous furnace — from the suspended roof in the walking beam furnace and the roller openings in the roller hearth furnace through to the sand seal in the tunnel kiln. We rely on zone-specific material concepts that optimise service life and energy efficiency.

Our teams plan repairs in close coordination with your production cycles in order to reduce shutdown times to a minimum. Execution follows documented quality and safety standards.

Typical challenges

01

Thermomechanical loading from continuous operation and temperature gradients

02

Mechanical abrasion from moving components (walking beams, rollers, kiln cars)

03

Sealing problems at roller openings, sand seals and rotary hearth seals

04

Energy losses through outdated or damaged insulation

05

Scale attack on the furnace hearth and support surfaces
