Abstract
The invention discloses a refractory brick for a boiler and relates to the technical field of manufacturing of refractory materials. The refractory brick comprises, by weight, 30-40 parts of calcined bauxite, 20-30 parts of mullite powder, 10-20 parts of quartz sand, 8-12 parts of Guangxi clay and 2-3 parts of calcium aluminate cement and is manufactured by mixing, blending, ageing, making blank, drying and baking. Compared with the prior art, the refractory brick for the boiler is good in heat resistance, insulation and sealing property and high in compression strength and is not easy to burn when used in the boiler, and service life is prolonged.
Description
Technical field
The present invention relates to refractory materials manufacturing technology field, especially a kind of boiler refractory brick.
Background technology
Burned flame in boiler and each heating surface are hedged off from the outer world by boiler refractory brick, therefore refractory brick used requires to have thermotolerance, thermal insulation and stopping property, compressive strength is high, and the thermotolerance of existing refractory brick, thermal insulation and good airproof performance, but compressive strength is lower, use as boiler refractory brick and easily damage, work-ing life is short.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of boiler refractory brick, to solve the lower problem of existing refractory brick compressive strength.
In order to solve the problem, the technical solution used in the present invention is: this boiler refractory brick, comprises the raw material of following weight part: bauxite clinker 30 parts ~ 40 parts, mullite powder 20 parts ~ 30 parts, quartz sand 10 parts ~ 20 parts, Guangxi clay 8 parts ~ 12 parts, aluminous cement 2 parts ~ 3 parts.
Described bauxite clinker, is called for short high aluminium material, the various high alumina bricks manufactured with its grog, is metallurgical industry and the widely used fire-resistant or impregnating material of other industry.
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 quartz sand, it is the quartz particles that quartzite processes through fragmentation, quartzite is a kind of silicate minerals of hard, wear-resisting, stable chemical performance, its main mineral constituent is SiO2, quartz sand is important industrial mineral raw material, is widely used in the industry such as glass, casting, pottery and refractory materials, smelting duriron, flux for metallurgy, metallurgy, building.
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.
Described aluminous cement, it coordinates by a certain percentage with calcium carbonate (Wingdale) with natural bauxitic clay or commercial alumina, makes, in refractory materials, be commonly used for bonding agent through calcining or electric smelting.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention adopts bauxite clinker, mullite, quartz sand to be main raw material, Guangxi clay and water glass are bonding agent, fire boiler refractory brick, the thermotolerance of this refractory brick, thermal insulation and good airproof performance, and compressive strength reaches 35MPa ~ 40MPa, be not easy to damage as boiler refractory brick, work-ing life improves.
