The invention relates to magnesial refractory material, the mass fraction of its component and each component is 20 30 parts of magnesia powder, 5 10 parts of silicon powder, 15 parts of chromium oxide, 13 parts of titanium oxide, 25 parts of zirconium oxide, 0.5 1 parts of carborundum.By above-mentioned technical proposal, a kind of magnesial refractory material of present invention refractoriness under alkaline environment is high, service life length, and the magnesia brick being prepared using the material is resistant to more than 2000 DEG C of high temperature.
Description
Technical field
The invention belongs to technical field of refractory materials, more particularly to a kind of magnesial refractory material.
Background technology
Refractory material refers to that refractoriness is not less than 1580 DEG C of a kind of inorganic non-metallic material.Refractoriness refers to refractory material
Bullet sample is in the case of no loading, and resistance high temperature action is without softening molten Celsius temperature.But only come with refractoriness
Definition cannot describe refractory material comprehensively, and 1580 DEG C are not absolute.Now being defined as all physicochemical properties allows it
The material used in high temperature environments is known as refractory material.Refractory material is widely used in metallurgy, chemical industry, oil, machine-building, silicon
The industrial circles such as hydrochlorate, power, dosage is maximum in metallurgical industry, accounts for the 50%~60% of total output.
Application to refractory in steel, non-ferrous metal, glass, cement, ceramics, petrochemical industry, machinery, boiler, light industry, electric power,
The every field of the national economy such as military project, is to ensure that above-mentioned industry production run and technology develop essential basic material,
Irreplaceable important function is played in hot industry production development.Wherein magnesia refractories is a kind of high-quality alkaline fire resisting
Material, has a variety of excellent performances, therefore enjoys consumers.But what existing magnesia refractories can carry
Temperature is limited and service life is short, it would be highly desirable to improves.
The content of the invention
It is an object of the present invention to propose a kind of high temperature magnesial that can be suitable for alkaline environment and service life length
Refractory material, thus more suitable for practicality.
The object of the invention to solve the technical problems is realized using following technical scheme.According to proposed by the present invention
The mass fraction of a kind of magnesial refractory material, its component and each component is 20-30 parts of magnesia powder, 5-10 parts of silicon powder, oxygen
Change 1-5 parts of chromium, 1-3 parts of titanium oxide, 2-5 parts of zirconium oxide, 0.5-1 parts of carborundum.
The object of the invention to solve the technical problems is also further realized using following technical scheme.
The mass fraction of foregoing magnesial refractory material, its component and each component is 20 parts of magnesia powder, silicon powder 5
Part, 1 part of chromium oxide, 1 part of titanium oxide, 2 parts of zirconium oxide, 0.5 part of carborundum.
