Abstract
The invention discloses a brick resistant to abrasion and corrosion and relates to the technical field of fireproofing material manufacturing. The brick comprises, by weight, 30-40 parts of mullite powder, 10-20 parts of silicon carbide fine powder, 3-5 parts of alumina micro powder, 5-15 parts of sillimanite fine powder, 3-5 parts of silica micro powder and 5-15 parts of Guangxi clay, and is manufactured by means of preparing ingredient, mixing, blank forming, drying and burning. Compared with the prior art, the brick resistant to abrasion and corrosion has the advantages that the brick is resistant to high temperature, high in thermal shock resistance, abrasive resistance and corrosion resistance, less prone to being damaged by abrasion and corrosion and long in service life.
Description
Technical field
The present invention relates to refractory materials manufacturing technology field, especially a kind of wear resistant corrosion resistant brick.
Background technology
In industrial production, many Thermal Equipments need with refractory brick, as will high temperature be born with the place of bed of material contact friction in cement rotary kiln, anti-thermal shock, also to resist erosion and the wearing and tearing of manufacture of cement material, because refractory brick used is at present high temperature resistant, thermal shock resistance is good, but wear resistance and erosion resistance low, easy wearing and tearing and suffer erosion and damage, work-ing life is short.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of wear resistant corrosion resistant brick, to solve refractory brick wear resistance used at present and the low problem of erosion resistance.
In order to solve the problem, the technical solution used in the present invention is: this wear resistant corrosion resistant brick, comprises the raw material of following weight part: mullite powder 30 parts ~ 40 parts, carbide fine powder 10 parts ~ 20 parts, alumina powder 3 parts ~ 5 parts, sillimanite fine powder 5 parts ~ 15 parts, silicon powder 3 parts ~ 5 parts, Guangxi clay 5 parts ~ 15 parts.
In above-mentioned wear resistant corrosion resistant brick technical scheme, technical scheme can also be more specifically: the particle diameter of described carbide fine powder and described sillimanite fine powder is 40 μm ~ 80 μm; Particle diameter≤5 μm of described alumina powder and described silicon powder.
Described mullite is the mineral that aluminosilicate at high temperature generates, have high temperature resistant, intensity high thermal conductivity coefficient is little, the features such as energy-saving effect is remarkable, mullite ore deposit be used to produce high-temperature refractory.
Described silicon carbide, formed by resistance furnace pyrotic smelting with raw materials such as quartz sand, refinery coke (or coal tar), wood chips, its stable chemical performance, thermal conductivity are high, thermal expansivity is little, wear resisting property is good, in order to the high grade refractory made, resistance to thermal shock, volume are little, lightweight and intensity is high, good energy-conserving effect.
Described aluminum oxide, through chemical treatment by bauxitic clay raw material, remove the oxide compound of silicon, iron, titanium etc. and obtain, can be widely used in the strengthening and toughening of the products such as various plastics, rubber, pottery, refractory materials, the wear resisting property particularly improving the compactness of pottery, smooth finish, cool-hot fatigue, fracture toughness property, creep-resistant property and macromolecular material product is particularly remarkable.
Described sillimanite, is a kind of brown, light green, light blue or white glassy silicate minerals, becomes mullite, can do high grade refractory when being heated to 1300 DEG C.
Described silicon powder, by natural quartz or the fused quartz micro mist through multiple tracks processes such as fragmentation, ball milling, flotation, pickling purification, high purity water process, possess that temperature tolerance is good, the excellent performance such as acid-alkali-corrosive-resisting, poor thermal conductivity, high insulation, low bulk, stable chemical performance, hardness are large, be widely used in the fields such as chemical industry, electronics, coating, senior paint.
Described Guangxi clay, it is the soft flame-proof clay that a kind of plasticity-is good, its granularity is superfine, the loose property of leaching and cohesiveness also fine, sintering range is wide, containing kaolinite often more than 70%, and based on disordered kaolinite, can significantly increase its plasticity-and folding strength, be high-quality bonding clay used for refractory material.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention adopts mullite powder, carbide fine powder, sillimanite fine powder to be main raw material, alumina powder, silicon powder and Guangxi clay are bonding agent, fire wear resistant corrosion resistant brick, this wear resistant corrosion resistant brick is not only high temperature resistant, thermal shock resistance is good, and wear resistance and erosion resistance high, not easy to wear and suffer erosion and damage, long service life.
