近年来,耐火纤维作为一种新型耐火材料由于容重小、导热系数低被广泛地应用于各部门。但由于我国耐火纤维产品品种单一,质量欠稳定,强度差,挂炉丝比较麻烦等原因而没有在电炉产品中应用。近几年,电炉行业研制成了另一种耐火材料——高强度轻质粘土砖。轻质粘土砖是大家熟悉的一种耐火材料,通常使用的是体积密度1.3和 In recent years, refractory fiber as a new type of refractory due to small capacity, low thermal conductivity is widely used in various departments. However, due to the single species of refractory fiber products in China, the quality is not stable, the strength is poor, hanging wire is too cumbersome and other reasons not in the electric furnace products. In recent years, the electric furnace industry has developed another refractory material - high-strength lightweight clay brick. Light clay brick is a well-known fire-resistant material, usually using the bulk density of 1.3 and
