Description

A kind of firing highly heatproof and shockproof bauxite brick and its production technology
Technical field
The present invention relates to Industrial Stoves Material Fields, and in particular to a kind of firing highly heatproof and shockproof bauxite brick and its production work Skill.
Background technology
High-alumina brick is one kind of refractory material, and the main component of this fire proof material brick is Al2O3.Alumina content exists A kind of 48% or more neutral refractory.By alumina or the higher raw material of other alumina contents through being molded and calcining. Thermal stability is high, and refractoriness is at 1770 DEG C or more.Resistance to slag is preferable, for building steel-smelting electric furnace, glass-melting furnace, cement rotary furnace by laying bricks or stones Deng lining.
Currently, existing high-alumina brick is typically alundum (Al2O3) (Al2O3) content, that is, aluminum content be 48% aluminosilicate property it is resistance to Fiery material product.But existing high-alumina brick primary raw material is alumina, the glassy composition contained in alumina is when the temperature rises Ternary system, quaternary system low melting point eutectic are easily generated, the thermal shock resistance of bauxite brick can be influenced.
Invention content
The present invention provides a kind of firing highly heatproof and shockproof bauxite brick, is existed with the glassy composition for solving to contain in above-mentioned alumina The problem of temperature easily generates ternary system, quaternary system low melting point eutectic, can influence the thermal shock resistance of high-alumina brick when increasing.
To solve the above problems, the technical solution adopted by the present invention is as follows:
A kind of firing highly heatproof and shockproof bauxite turn, it is characterised in that:The firing highly heatproof and shockproof bauxite brick, including it is following The component of parts by weight:52-58 parts of high alumina bauxite mixture, 15-20 parts of sillimanite powder, 8-12 parts of cordierite powder, aluminium oxide 3-8 parts of powder, 10-15 parts of Guangxi white clay, 1-5 part of zircon powder, 1-5 part of carbide fine powder.
Alumine, referred to as high aluminium material.The essential mineral of high aluminium material is diaspore and high alumina silica composition.Diaspore contains Amount increases with the raising of the ratio of alundum (Al2O3) and silica.Secondary mineral are rutile, take off iron ore etc..Sometimes Also contain a small amount of Baume stone and dickite.
Alumina is a kind of aluminum oxide ore, is in yellow to red because containing iron oxide, therefore also known as " bauxite ".Alumina is anti- The ability that acid, basic clinker corrode is strong, and elevated temperature strength is high, is widely used in the industries such as steel, coloured, but its anti-chilling thermal energy power Difference, high volume stability are bad, lead to the deformation and peeling of material, reduce the service life of material.
Sillimanite, also known as sillimanite, it is a kind of brown, light green color, light blue or white glassy silicate mineral. The crystal of sillimanite be column or needle-shaped, these crystal condense together often in threadiness or it is radial, with silk gloss or Glassy lustre.Mullite is become after sillimanite heating, is used as high grade refractory.
Cordierite is a kind of silicate mineral, is originated in schist, gneiss and alteration igneous rock, and fire resistance is good, is heated swollen Swollen rate is low.
Aluminium oxide, chemical formula Al2O3.It is a kind of compound of high rigidity, fusing point is 2054 DEG C, and boiling point is 2980 DEG C, in height Ionizable ionic crystals under temperature is usually used in manufacturing refractory material, and industrial alumina powder is by bauxite (Al2O3·3H2O) and Prepared by diaspore.
Guangxi white clay is a kind of soft kaolin, can also be soft flame-proof clay.The ingredient of Guangxi white clay includes unordered Kaolinite, quartz and micro ilmenite ores, and Guangxi white clay has the characteristics that good plasticity, good fluidity, associativity are good etc..
Zircon is natural mineral matter, is usually used in refractory material, and zircon also has lower thermal expansivity, higher leads It is hot, and have stronger chemical stability, main component is zirconium dioxide.Zirconium dioxide, chemical formula ZrO2, it is zirconium Main oxides are white odorless, tasteless crystal under usual condition, are insoluble in water, hydrochloric acid and dilute sulfuric acid.It is general often to contain on a small quantity Hafnium oxide.Chemical property torpescence, and the property with high-melting-point, high resistivity, high refractive index and low thermal coefficient of expansion, Important heat-resisting material, ceramic insulating material and ceramic opacifier are made it, is also the primary raw material manually bored.
Diamond dust also known as silicon carbide (are needed when production green silicon carbide with quartz sand, petroleum coke (or coal tar), sawdust Add salt) etc. raw materials formed by resistance furnace pyrolytic semlting, stable chemical performance, thermal coefficient are high, coefficient of thermal expansion is small, wear-resisting Performance is good.
Existing bauxite brick, generally using alumine and alumina as raw material, refractoriness is preferable, belongs to advanced fire proofed wood Material, but alumina thermal shock resistance is poor, anti-chilling thermal energy force difference, high volume stability are bad, lead to the deformation and peeling of material, Reduce the service life of material.
From the above problem, what the present invention innovated is found that the cooperation of zircon powder and alumina, can effectively improve aluminium The thermal shock resistance of alumina brick.Firing highly heatproof and shockproof bauxite brick in the present invention, using high alumina bauxite mixture as primary raw material, Expected supplemented by sillimanite powder, cordierite powder, alumina powder and Guangxi white clay, then is aided with zirconium dioxide to improve the anti-of bauxite brick Thermal shock resistance.Alumina is arranged in pairs or groups in proportion with sillimanite powder, and the aobvious porosity of bauxite brick can be made suitably to increase, help to improve aluminium alum The anti-scour property of cob brick.Cordierite powder is arranged in pairs or groups in proportion with high alumina bauxite mixture and zircon powder, can be appropriate The thermal expansion for reducing bauxite brick, to effectively improve the thermal stability of bauxite brick.Alumina powder is mixed with high alumina bauxite Material is arranged in pairs or groups in proportion, the aluminum content that can be effectively increased in bauxite brick, to improve the refractoriness of bauxite brick.Guangxi white clay It arranges in pairs or groups in proportion with high alumina bauxite mixture, can effectively enhance the plasticity of high-alumina brick, contribute to being pressed into for high-alumina brick Type.Contain a large amount of zirconium dioxides in zircon powder, zirconium dioxide has low thermal coefficient of expansion and preferable high temperature resistant property, zirconium Diamond stone powder and high alumina bauxite mixture dispensing in proportion, repressed, burning process, the first one-step forming of bauxite brick, therein two Zirconium oxide is undergone phase transition so that several fine cracks is formed inside cob brick, when temperature change generates thermal stress, these are small Crackle can be such that the energy in refractory material is released, to improve the thermal shock resistance of bauxite brick.
Therefore, firing highly heatproof and shockproof bauxite brick provided by the invention, can effectively improve the anti-thermal shock of bauxite brick Property.
In addition, cordierite powder is arranged in pairs or groups with zircon powder, sintering model can also be widened under the premise of not influencing thermal stability It encloses.
To achieve the above object, the present invention also provides the production technologies of above-mentioned firing highly heatproof and shockproof bauxite brick, including with Lower step:
(1) it mixes, stir:Proportionally sequentially add high alumina bauxite mixture, water, sillimanite powder, cordierite powder and Alumina powder is mixed 10 minutes, adds Guangxi white clay, is mixed 10 minutes, obtains head product;
