At present, the firing of table ware, sanitary ware, electronic ceramic and ceramic and craft ceramic mostly adopt the highly efficient thermal equipment such as tunnel kiln, shuttle kiln and so on. The supports of kiln car mostly are silicon-carbide products; especially crossbeams made of the very expensive R-SIC increase the expenses of consumption by a big margin. Although R-SIC square-beam has better high temperature properties, it is difficult for it to overcome its innate weakness of bad oxidation resistance, which can be proved form that its flexural strength at high temperature sharply reduces after used for a period of time, for the reason of that the structure becomes fragile due to oxidation. Undoubtedly, its using life is fairly short.

Our company introduces the SF-F square-beam properly, it is produced with advanced technology and imported raw materials. SF-F square-beam has good properties at high temperature, thermal shock resistance, straightness and flatness and can bear heavier load of products, it also can be used in any atmosphere at high temperature without oxidation and reduction. The life will up to 300 times.
