Kiln furniture and tunnel kiln cars

Steuler‘s refractory concepts and the associated kiln furniture are specifically designed for applications in the heavy ceramics industry and often make the key difference to the quality of the end product.

Steuler tunnel kiln cars and kiln furniture are designed to be as lightweight as possible while maintaining structural stability and safety, thus ensuring durability and a long service life.

Tunnel kiln cars are the most heavily stressed pieces of equipment used in tunnel kilns. Rapid cyclical heating and cooling, the physical loads involved during loading and unloading and the cleaning process all result in stresses within the car system that have to be sustainably and reliably managed over their long service lives.

• Lightweight but stable construction with low inherent weight
• Pultruded perimeter blocks and cover slabs provide for lower heat transfer thus reducing energy consumption
• Combinations of pressed and pultruded materials (dry-pressed perforated shelves and batts, trays, supports), cordierite-containing materials feature excellent thermal shock properties thus maximising the service life of the car system
• Andalusite- and bauxite-containing materials allow for high operating temperatures of > 1,400 °C

Our customers benefit from our decades of experience and the continuous further developments by our development department and engineering. The service life of the kiln furniture is extended and the running operating costs are reduced. Steuler kiln furniture is customer-friendly, the solutions diverse, the operational reliability perfect. At Steuler, thermal, mechanical and geometric requirements are considered together and combined in a meaningful qualitative unit.

Steuler kiln furniture is precision-manufactured using the dry-press or pultrusion method depending on application. This results in tight dimensional tolerances of the workpieces and minimises the amount of post-processing required, a big advantage when it comes to automating production lines. The materials we use, in particular cordierite, andalusite and bauxite, are characterised by excellent thermal shock resistance – a key requirement for rapid kiln cycles.
