Magnesium aluminum silicate fibrous refractory material
The present invention relates to a formula of a refractory material, and particularly to a magnesium aluminum silicate fibrous refractory material. The magnesium aluminum silicate fibrous refractory material is characterized in that the formula of the magnesium aluminum silicate fibrous refractory material comprises the following components in parts by weight: 45-52 parts of magnesium oxide and oxidizing calcareous materials, 1-2 parts of aluminum silicate fibers with a diameter of 2-4 microns and a length of <=1 cm, 1-2 parts of glass microspheres with a particle size of 10-250 microns and a wall thickness of 1-2 microns, 8-15 parts of silicon carbide, 12-14 parts of quartz sands, 0.2-6 parts of an Mg-Zr alloy, 3-8 parts of magnesium aluminum silicate and 2-5 parts of a binder for a carbon-containing refractory material. The magnesium aluminum silicate fibrous refractory material prepared by using the technology of the present invention considers oxidation resistance, high temperature resistance, slag penetration resistance, thermal shock resistance and productivity.
