What does the export foreign trade SK series refractory brick represent?

SK is a brand name representation method for foreign refractory bricks, representing the index of refractoriness (Seger cone). SK a test index name for a foreign test method for the refractoriness of refractory bricks, which is slightly different from our domestic test method for the refractoriness of refory bricks. Refractoriness refers to the temperature at which a material reaches a specific softening degree under the action of high temperature, characterizing the material's resistance to high. The meaning expressed by refractoriness is different from the melting point. The melting point is the temperature at which the liquid phase and solid phase of a crystal are in equilibrium.ractoriness is the temperature at which a multiphase body reaches a certain specific softening degree. Therefore, to characterize the softening and melting characteristics of this material at high temperature, can only be measured by refractoriness. Refractoriness is not an absolute physical quantity unique to a substance, but a relative technical index of the material that reaches a specific soft degree under specific test conditions. Zhengzhou Hua ang Refractory Material Co., Ltd. produces SK34 refractory bricks, SK35 refory bricks, SK36 refractory bricks, SK37 refractory bricks, SK38 refractory bricks, which are exported to foreign regions such as South, Japan, Indonesia, Vietnam, South Africa, Kazakhstan, etc. Products are used for: boiler, cement kiln, glass kiln, tunnel kil, rotary kiln and vertical kiln, etc., as well as various kiln linings and thermal equipment, and are widely used in metallurgy, chemical industry,amics, coke, carbon, casting, machinery, electric power, building materials, petroleum and other industries.
