Kiln furniture is used in heating processes while in the production of individual pieces just like ceramic or metal parts. The kiln furniture carries the charge and is intended to make sure that the components neither deform nor stick to one another. In order to achieve a high product quality and the lowest reject rate, the charge will be heated and cooled while homogeneously and uniformly as possible, regardless of the position within the furnace. The kiln furniture plays a crucial role in the heat management with the furnace. The interaction belonging to the charge with the furnace atmosphere is likewise strongly influenced by that kiln furniture. In order to manipulate the gas exchange, in combination with different carriers and discs, capsules are often needed, in which the heating material is placed.
In addition to the actual material, the kiln furniture must always be heated during the particular heat treatment processes. Therefore, energy consumption rises – should of small components, it might even be doubled. Kiln furniture components are wearing areas, which must be replaced regularly due to thermomechanical and chemical strains during use. Their production causes more energy expenditure and increases the operating costs of the furnace plants. In order to raise the energy efficiency from the heat treating processes so to reduce the costs, the heat capacity in the kiln furniture must end up being reduced and their living cycle increased.
