Lightweight refractory castable light brick sand with cement, refractory powder and lightweight aggregate, their variety and amount of different properties are also different; superplasticizer admixture castable, water loss and strength increase is obvious; incorporation of additional material accumulation density of small, lightweight castable castable reduces bulk density, improve its insulation properties, but the intensity decreased exponentially, and the more the amount is more obvious. Therefore, based on thermal furnace conditions of use and the use of castable parts, reasonable preparation and selection of refractory castable light brick sand to reach the furnace longevity and energy saving. Lightweight refractory castable preparation and forming corundum castable, light castable refractory castable and finally to basically the same, the difference is lightweight aggregate density is small, easy to absorb water, so the mixing should say good light aggregate, pour compulsory mixer, the first half of the water plus the amount of water, wet mixing uniformity, coupled with refractory powder and cement, and add the remaining water mixing. When forming, lightweight aggregate easy to float, causing delamination, so vibration time should be shorter, should be controlled. Light brick refractory castable in accordance with the requirements of the sand, forming the initial setting after mixing should be cured in a moist environment. 1 day Chaimo conservation, portland cement and cement CA-50 lightweight refractory castable test body, should continue conservation six days and two days respectively. Then, to test its performance. Light brick sand formulated refractory castable bulk density, typically 1.18-1.58 g? Cm3. Drying compressive strength greater than 6Mpa, with heating temperature, the strength decreased to 1300 ℃, the light casting material strength has gone up, which is caused by the powder is sintered.
