Kiln furniture
Ceramics are fired at high temperatures. This is where they get their final properties. Since the ceramic products undergo various transformation processes during the firing process, these products are not always dimensionally stable during the "firing". With a view to efficient condensing technology, so-called kiln furniture used. They are used to arrange and stabilize the blanks in a furnace so that they do not deform or stick together. They are usually made of ceramic or metal, or a mixture of these two materials. In contrast to this, a bomb is an unfired auxiliary body that experiences almost the same shrinkage during firing as the material to be fired.
In addition to this supporting effect, the kiln furniture also has the disadvantage that they strongly influence the energy consumption during the firing process. The process technicians or the designers of the furnace manufacturer have in the development of the various furnaces, such. B. tunnel kilns to optimize the design of kiln furniture, especially with regard to their energetic influence.
