Feature: Si Mullite brick is based on the large and medium-sized cement rotary kiln refractories for demanding,based on conventional products, by adding mineralizerand other trace elements, and further strengthen the property of thermal shock resistance and high temperature performance. Has the characteristics of high thermal shock resistance, high strength, good abrasion resistance, high temperature resistance to chemical corrosion and so on, in accordance with the refractoriness under load can be divided into 1680,1650,1550 and three varieties, in the course of continuous form a protective layer,characterized by reduced ring,mainly is suitable for the large and medium-sized cement kiln transition zone etc.
Si Mullite brick uses the high quality silicon carbide and high pure Gong soil clinker as the main raw material,using the refractory composite modified principle, adding oxide superfine powder and special additives,the series products of dense glaze film is formed on the high temperature surface, prevent the refractory lining and the material response, so that the refractory products high chemical resistance and excellent wear resistance,is the best material of large cement kiln anti erosion, thermal shock resistance,abrasion resistance.
