Description
Technical field
The present invention relates to a kind of energy-conservation magnesia brick of hot environment based on thermal boundary and radiative recombination function and preparation technology thereof, belong to ceramic subject fire resisting material field.
Background technology
Energy-conservation is the significant problem of thermal technology's stove user (as iron and steel enterprise, building materials enterprise).In recent years, the enterprise of domestic a large amount of use thermal technology stove is forced to stop production because energy consumption exceeds standard transformation, develops new power-saving technology and becomes the matter of great urgency.The accumulation of heat loss of Industrial Stoves masonry and the heat lost by radiation of stove outside surface, generally account for the 24-45% of fuel consumption.Traditionally, low by thermal conductivity, that thermal capacity is little light material does furnace binding material, can fuel saving consumption.But there is fatal weakness in light material, intensity is low, wear resisting property is poor, pore is many, impermeabilisation and erosion-resisting characteristics poor, the working lining of Industrial Stoves is made not adopt lightweight refractory, but adopt the strong and anti abrasive heavy refractory materials of resistance to fouling at hot operation end (more than 1000 ~ 1600 DEG C), heavy material exactly thermal capacity is large, thermal conductivity is high, be unfavorable for that the incubation chamber of kiln is energy-conservation, in order to reach the effect of post, so (because temperature has been down to less than 1000 DEG C) adopts light material after heavy material, as lagging material, the effect of this kind of insulation is incubated in low-temperature end, in fact kiln has absorbed a large amount of energy, effect is certainly not as being directly incubated more energy-conservation in temperature end.
High in order to solve heavy refractory materials intensity, wear-resistant, anti-erosion is good, but thermal conductivity is high, thermal capacitance is large, heat insulation effect is poor, and lightweight refractory thermal conductivity is low, thermal capacitance is little, high insulating effect, but intensity is low, easy to wear, the contradiction of anti-erosion difference, the method of current employing smears a kind of heat radiation coating on the basis of heavy material, but the coating smeared often combines not strong with heavy material, easy peeling comes off, in addition, the wear resisting property of coating itself is not strong, attrition gradually under the impact of long air-flow and dust, the energy-saving effect of kiln is caused to be deteriorated gradually, finally lose radiation in kiln, the effect of kiln Surgery therapy.
For thermal technology's stove, according to Boltzmann law Q=E
hδ (T
h 4-T
c 4) (wherein Q is the total energy that unit area gives off within the unit time; E
hfor radiation coefficient, or be emittance; δ is this special fence-Boltzmann constant; T
hthe temperature of high temp objects; T
cenvrionment temperature), therefore, high-temperature service environment determine radiative transfer account for total heat transmit more than 80%.Strengthening radiative transfer is the only way of furnace energy-saving, instead of taking in the past reduces thermal conductivity as uniquely energy-conservation approach.The infrared emittance of furnace wall is brought up to 0.9 by current 0.5, can realize more than 15% energy-conservation.This means that thermal technology's stove thermo-efficiency can improve more than 15% by strengthening radiative transfer.
