| 高铝砖与抗剥落高铝砖比较，抗剥落高铝砖是用高铝矾土和锆英石为原料的，强度高，抗化学腐蚀，热膨胀系数低，导热系数低。而高铝砖是用高铝矾土为原料，抗 化学腐蚀性能不如抗剥落高铝砖，主要是抗剥落高铝砖比高铝砖热震稳定性好。 Compared with anti-spalling high-alumina bricks, anti-spalling high-alumina bricks are made of bauxite and zircon with high strength, chemical corrosion resistance, low thermal expansion coefficient and low thermal conductivity. High-alumina brick is made of high-alumina bauxite. Its chemical corrosion resistance is not as good as that of spalling-resistant high-alumina brick. The main reason is that spalling-resistant high-alumina brick has better thermal shock stability than high-alumina brick. 抗剥落高铝砖抗剥落能力强，同时具有抗钾、钠、硫、氯及碱性盐的侵蚀，低热导率等性能，是水泥窑过渡带及分解带的理想材料，显著特点就是耐热震性能良好，适应环境能力强。多用于回转的预热带或分解炉内及篦冷机等部位。 Anti-spalling high-alumina brick has strong anti-spalling ability, anti-erosion of potassium, sodium, sulfur, chlorine and alkaline salts, low thermal conductivity and other properties. It is an ideal material for transition zone and decomposition zone of cement kiln. Its remarkable characteristics are good thermal shock resistance and strong environmental adaptability. It is mostly used in rotary preheating or calciner and grate cooler. |
