Preparation method of low-heat-conduction multi-layer composite magnesium aluminate spinel brick for rotary kiln
The invention relates to the technical field of refractory energy-saving materials, and discloses a preparation method of a low-heat-conduction multilayer composite magnesium aluminate spinel brick for a rotary kiln, the low-heat-conduction multilayer composite magnesium aluminate spinel brick comprises a working layer, a heat preservation layer and a heat insulation layer, and is characterized in that the working layer is connected with the heat preservation layer, a notch is formed in the heat preservation layer, and the heat insulation layer is located in the notch; the working layer is prepared from an aggregate, a powder material, a binding agent and an additive, the sum of the aggregate and the powder material is 100 wt%, the aggregate accounts for 60-65 wt%, and the powder material accounts for 35-40 wt%. The low-heat-conduction multi-layer composite magnesium aluminate spinel brick for the rotary kiln and the preparation method thereof have the beneficial effects that the product has excellent high-temperature use performance by virtue of the advantages of a multi-layer composite structure, meanwhile, the heat conductivity coefficient of the brick is far lower than that of similar products, and the surface temperature of a cylinder can be greatly reduced when the brick is used in a transition zone of the cement kiln according to a test; and the temperature is 50-80 DEG C lower than that of similar products on the market.
本发明涉及耐火节能材料技术领域，且公开了回转窑用低导热多层复合镁铝尖晶石砖的制备方法，包括工作层、保温层和隔热层，其特征在于：所述的工作层和保温层相连，在保温层上有一个缺口，隔热层位于该缺口内；工作层是由骨料、粉料、结合剂、外加剂制成，骨料、粉料之和为100wt％，骨料占60‑65wt％，粉料占35‑40wt％，该回转窑用低导热多层复合镁铝尖晶石砖的制备方法，本发明的一种回转窑用低导热多层复合镁铝尖晶石砖及其制备方法的有益效果是：本发明产品依靠多层复合结构优势，有着优异的高温使用性能，同时其导热系数远低于同类产品，经测试使用在水泥窑过渡带能大大降低筒体表面温度，相对于市场上同类产品低50～80℃。
