Abstract

The invention relates to a novel magnesia refractory material comprising the components in parts by mass: 35-40 parts of magnesite particles, 15-20 parts of silicon micro-powder, 3-5 parts of calcium oxide, 3-5 parts of chromic oxide, 2-4 parts of manganese oxide, and 2-4 parts of silicon dioxide. By the technical scheme, the novel magnesia refractory material has the advantages of high refractoriness, strong corrosion resistance and long service life under an alkaline environment, and a magnesite brick prepared from the material has high density and can resist a high temperature of more than or equal to 2300 DEG C.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, in particular to a novel magnesia refractory material with high temperature resistance. Background technique [0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting without load. However, it is not possible to fully describe refractory materials only by the definition of refractoriness, and 1580°C is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are used in the largest amount in the metallurgi...
