Feuerfest-Systeme Kiln furniture
STEULER-KCH kiln furniture for traditional and new areas of application Above: Anchored toothed support structures ensure high stability, even for automatic cycles. Shelf spacing can be varied in the toothed supports. STEULER-KCH kiln furniture is customer-friendly, providing versatile solutions and perfect operating reliability. STEULER-KCH considers the thermal, mechanical, chemical and geometrical requirements as a whole and combines them in a logical qualitative unit. For this purpose, we use a variety of raw material components including cordierite, mullite, andalusite and corundum. Our customers benefit from our decades of experience and the continual product development carried out by our research and development department. The service life of your kiln furniture is extended and operating costs are reduced. After sales service is a high priority at STEULER-KCH. A wide range of solutions and comprehensive service ensure operational reliability and performance. Our products and our knowhow are used by leading firms all over the world. Our own laboratories for research and development, our own production facilities and international marketing by our trained staff guarantee know-how and reliability from a single source, certified in accordance with the internationally recognised quality management standard DIN ISO 9001/EN 29001. STEULER-KCH kiln furniture in the ceramics industry Continually rising energy costs and frequently changing products in the ceramics industry demand versatile rack systems. Optimum use must be made of the kiln space available. The variable kiln car system from STEULER-KCH offers the required flexibility and stability. This means STEULER-KCH kiln car systems are also suitable, among other things, for use in automatic tunnel kilns, muffle kilns and bogie hearth furnaces. When there are extreme mechanical stresses, especially during long processing periods in a tunnel kiln, STEULER-KCH has developed a special plug-in system. Racks are installed stably without mortar, so an undisturbed service cycle is guaranteed. Special interlocking nubs also compensate for temperature stresses in the heating and cooling phases. Above: Tunnel kiln car for the firing of roof tiles in H cassettes. Lightweight but sturdy car assembly with special supports extended down to the car chassis for stabilisation.

Above: Underlay plate with very good resistance to temperature variation in the powder metallurgy industry. STEULER-KCH kiln furniture for powder metallurgy and technical ceramics Above: Skillet for automatic loading and circulation in the ferrite industry. The finishing costs for powder metallurgical sinter mouldings can be minimised by the use of special kiln furniture. The smoother the firing surface, the smoother the moulding after heat treatment. Support points can be arranged at different heights and shrinkage can also be preset to any degree needed. Steuler kiln furniture is produced using a dry press process where all dimensions can be controlled with high precision. This ensures close dimensional tolerances in the workpieces and minimises finishing work, a definite bonus when automating production lines. The materials we use, especially cordierite, are characterised by very high resistance to temperature variations a crucial requirement for fast kiln cycles. Take advantage of our many years of experience and our knowhow even at the development stage of your sinter moulded components. We can advise you and together we can then develop solutions which also minimise your production costs. Our own tool-making facilities give us great flexibility in fulfilling your requirements. As a plant operator, you can also benefit from our close contacts with kiln and machine constructors. Practical requirements can be met flexibly and innovatively by our research and development departments. Technical ceramics We offer customer-specific design and efficient solutions for use as firing and transport aids. These may be capsules, plates, frames or supports, for example. Electroceramics For the sintering of electroceramics (e.g. ceramic components, capacitors, varistors, piezo-ceramics, soft and hard ferrites), we also produce state of the art kiln furniture. High precision thin-walled designs ensure trouble-free use in automatic cycles. Low-MgO versions, specially developed for use in roller kilns, minimise reactions with the support rollers and also with the products being fired. Magnetic ceramics For the firing of hard ferrites in roller kilns, a special low-mgo version has been developed to prevent reactions with the support rollers and the products being fired. Left: Skillets with capsules in technical ceramics, in which the capsules are locked together and the skillet is also locked to each capsule. STEULER-KCH Kiln furniture 4 5 Kiln furniture STEULER-KCH
