轻质矽砖是近年来发展的一种新型隔热材料,在1941年,苏联耐火材料研究院即已研究成功。但是,大规模地生产及使用还是近几年的事。使用实践证明,轻质矽砖具有广泛的用途:它可以直接作为加热炉炉衬,顶盖,在不宜于使用轻质粘土砖地方可以使用轻质矽砖。在加热炉炉衬中使用轻质矽砖可以缩短加热期,降低35%的燃料消耗量(与粘土砖比较)。耐火材料工业窑炉炉顶部位使用轻质矽砖,可延 Light silica bricks in recent years developed a new type of insulation materials, in 1941, the Soviet Union Institute of Refractories has been successfully studied. However, large-scale production and use is still a matter of recent years. Practice has proved that lightweight silica bricks have a wide range of uses: it can be used directly as a furnace lining, roof, light clay brick should not be used where light silica bricks. The use of lightweight silica bricks in the furnace lining can shorten the heating period and reduce the fuel consumption by 35% compared to clay bricks. Refractory industrial furnace top of the furnace using lightweight silica tiles, renewable
