Refractory Materials Improve Firing Efficiency And Save Energy
Refractory Materials are the most important auxiliary materials to ensure the sintering efficiency and energy saving of ceramic kiln. The correct choice and use of Refractory Materials for ceramic production enterprises is very important. At present, the domestic building of sanitary ceramics manufacturers have been faced with from big to do a strong qualitative transformation process, in the case of severe ceramic homogeneity, overproduction and other harsh conditions, which
enterprises to the production of fine-grained control, the optimal allocation of energy consumption, environmental pollution requirements to do better, the enterprise will certainly be more vigorous. Therefore, the optimization and allocation of Refractory Materials for the development of enterprises is very important. In the process of optimizing configuration, we can see that a variety of new Refractory Materials have been playing a leading role. We must attach importance to and adopt advanced technology to strengthen the quality control of the products.
Refractory Materials are a branch of the silicate discipline, and silicate materials are generally divided into: cement, glass, ceramics and Refractory Materials. And Refractory Materials from the point of use can be divided into: metallurgical Refractory Materials, Cement industry Refractory Materials, glass industry Refractory Materials and other Refractory Materials. In which ceramic Refractory Materials are classified as other refractory materials, building sanitary ceramics
belongs to a branch of ceramics, so the construction of sanitary ceramics with Refractory Materials for granted is a class of other Refractory Materials. In theory, Refractory Materials and unshaped refractory materials, but the general unshaped refractory to cement, metallurgical kiln, and the glass industry and ceramic industry is not used, so we discuss the use of refractory materials in ceramics when the habit does not discuss unshaped refractory materials, but to emphasize that unshaped refractory materials, especially refractory aggregates, refractory castable and the cementing agent of refractory materials, can play an immeasurable role in the construction of some ceramic kilns, not to discuss not to attach importance to, but to give more attention to it, possibly the author will discuss the unshaped refractory materials and system of ceramic industry.
Kiln refractory materials, including kiln wall Han top, generally divided into three layers inside and outside, the inner layer for light insulation cotton, felt, plate, etc., medium-weight or lightweight insulation brick, the outer layer to red brick or low-temperature insulation brick mainly. The light insulating layer in the inner layer has developed rapidly in recent years, taking the low-temperature mullite fiber as the main, considering the High-temperature mullite fiber, the high alumina mullite fiber, the zirconium mullite fiber and so on, the temperature from the 1200℃~1600℃ system. The process of drawing, throwing, spraying, etc. is adopted in the fiber making process. The inner layer is also useful light mullite, high aluminum, such as lightweight brick or plate, to light alumina, mullite and other hollow ball brick as the main body. Middle-level heavy materials still use low aluminum high silicon, high alumina low silicon, mullite and Cordierite, Gem and mullite materials made of heavy materials mainly. The outer layer of low-temperature Refractory Materials mainly bauxite, caramel, clay and other production, relatively low aluminum content, poor temperature resistance but lower prices.
Kiln truck with Refractory Materials have kiln surface, kiln car bracket, burning plate, casing bowl, etc., in addition to the basic structure of the kiln to form materials, the rest of the material is collectively known as kiln materials. Kiln car with refractory and kiln wall material is basically the same. Kiln materials according to different conditions have mullite, high alumina mullite, Cordierite, Mullite-cordierite, SIC, oxide-bonded silicon carbide, silicon nitride bonded silicon
carbide and so on. In addition to the above materials, modern ceramic kiln can not ignore the roller kiln ceramic sticks, now the ceramic sticks have alumina, quartz, silicon nitride, silicon carbide quality, recrystallization silicon carbide, silicon nitride bonded silicon carbide and so on. The sticks used in the building sanitary ceramic roller kiln are mainly of high alumina quality.
