Abstract
The invention relates to a high-temperature-resistant magnesium oxide refractory material comprising the components in parts by mass: 30-35 parts of a magnesium ore powder, 25-30 parts of a silicon micro-powder, 2-5 parts of calcium oxide, 2-5 parts of ferric oxide, 2-5 parts of titanium oxide, and 3-6 parts of a silicon-magnesium alloy. By the technical scheme, the high-temperature-resistant magnesium oxide refractory material has the advantages of high refractoriness, long service life, and good anti-corrosion effect, and a magnesite brick prepared by the material has high density and can resist a high temperature of more than or equal to 2500 DEG C.
Description
Technical field
The invention belongs to technical field of refractory materials, particularly relate to a kind of resistant to elevated temperatures magnesia refractory materials.
Background technology
Refractory materials refers to that refractoriness is not less than a class ceramic of 1580 DEG C.Refractoriness refers to that refractory materials cone-shaped body sample is not having in loading situation, resists high temperature action and does not soften molten centigradetemperature.But only define with refractoriness and can not describe refractory materials, 1580 DEG C is not absolute comprehensively.Now be defined as the material that all physicochemical property allow it to use in high temperature environments and be called refractory materials.Refractory materials is widely used in the industrial circles such as metallurgy, chemical industry, oil, machinofacture, silicate, power, and in metallurgical industry, consumption is maximum, accounts for 50% ~ 60% of ultimate production.
Application to refractory is in the every field of the national economy such as iron and steel, non-ferrous metal, glass, cement, pottery, petrochemical industry, machinery, boiler, light industry, electric power, military project, be ensure above-mentioned industry production run and the requisite basic material of technical development, in hot industry production development, play irreplaceable vital role.Wherein magnesite refractory is a kind of high-quality basic refractory, has multiple excellent use properties, therefore enjoys consumers.But the temperature that existing magnesite refractory can carry is limited and work-ing life is short, urgently improves.
Summary of the invention
The object of the invention is to, propose a kind of high temperature resistant and magnesia refractory materials of long service life, thus be more suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to the resistant to elevated temperatures magnesia refractory materials of one that the present invention proposes, the mass fraction of its component and each component is magnesite powder 30-35 part, silicon powder 25-30 part, calcium oxide 2-5 part, ferric oxide 2-5 part, titanium oxide 2-5 part, Si-Mg alloy 3-6 part.
The object of the invention to solve the technical problems also adopts following technical measures to realize further.
Aforesaid resistant to elevated temperatures magnesia refractory materials, the mass fraction of its component and each component is 30 parts, magnesite powder, silicon powder 25 parts, 2 parts, calcium oxide, ferric oxide 2 parts, titanium oxide 2 parts, Si-Mg alloy 3 parts.
Aforesaid resistant to elevated temperatures magnesia refractory materials, the mass fraction of its component and each component is 32 parts, magnesite powder, silicon powder 27 parts, 3 parts, calcium oxide, ferric oxide 3 parts, titanium oxide 3 parts, Si-Mg alloy 4 parts.
