Light weight refractory is the most important auxiliary material for ceramic kilns to ensure firing efficiency and energy-saving. The proper selection and using of refractory materials is very important for ceramics production enterprise energy conservation. A variety of new refractories has been playing a leading role in refractory process optimization and configuration. The choice of kiln materials and kiln car materials is one aspect of energy efficiency in ceramic firing process.

     Furnaces of roller kiln and tunnel kiln is divided into preheating zone, firing zone, heat zone and cooling zone. Proper refractory materials can be selected according temperature curve segment in preheating zone. But firing zone and insulation zone are combined to firing zone in modern kiln. This is the stage with highest temperature and maximum cooling phase which refractory material selection is very important. The principle to choose refractory for kiln and kiln car is energy-saving insulation according kiln situation and chemical properties such as intensity, corrosion etc. General speaking, it is better to use new refractory as internal insulation such as aluminum silicate fiber and board or felt made from high alumina fibers. And other light weight refractory material can be as a supplement. Ceramic fiber can be divided into common ceramic fiber, standard ceramic fiber blanket, HP ceramic fiberblanket, HZ ceramic fiber blanket based on operation temperature. These product can be used in different parts of the kiln furnace. As the top export ceramic fiber brand, CCEWOOL has been serving 300 large scale furnace enterprises in more than 30 countries. CCEWOOL ceramic fiber blanket is made through special inside needle flower technology and its shot content is only 12%.
