摘要

高铝耐火材料由于具有较高的耐火度和抗渣性，在高温工业中广泛应用于炼钢厂、玻璃炉和水泥回转窑的内衬。原料中的杂质反应形成玻璃相，玻璃相在高温下可以熔化成液体。耐火材料的断裂模量很大程度上取决于玻璃相的含量和组成。本文在不同理论的基础上，采用拟合的方法对高铝砖的冷、热断裂模量进行了研究。结合高铝耐火材料的相组成、断口形貌和孔隙率分析了玻璃相对断裂模量的影响。

The Effect of the Glass Phase on the Modulus of Rupture of High-Alumina Refractories

Owing to their high refractoriness and slag resistance, high-alumina refractories are widely used in the lining of steelmaking furnaces, glass furnaces and cement rotary kilns in high-temperature industries. The impurities in the raw materials react to form the glass phase, which can melt into liquid at high temperatures. The modulus of rupture of refractories depends intensively on the content and composition of the glass phase. In this work, the cold and hot modulus of rupture for high-alumina bricks were investigated by means of fitting based on different theories. The effect of the glass phase on the modulus of rupture was analyzed by combining the phase composition, morphology of fracture surfaces and porosity for high-alumina refractories.
