一、综合炉底好——是与全粘土砖或全高铝砖炉底比较而言的四十年代前广泛采用的全粘土砖或全高铝砖高炉炉底,在高炉生产中常发生炉底及炉缸破穿事故,严重者被迫停炉大修,从而缩短了这类铝硅酸盐材料炉底的寿命。1963年对我国大多数300米0以上高炉的铝硅酸盐材料炉底寿命进行的调查表明,高炉一代平均寿命仅为4年9个月。武钢2号高炉(1436米~3)第一代全高铝砖炉底曾发生烧穿事故,一代寿命只有5年7个月。当然全粘土砖炉底偶而也有长寿的。国外有人在较长寿命的粘土砖炉底及炉缸的大修拆除时,了
First, the integrated furnace is good - is compared with the whole clay brick or full-height aluminum brick furnace compared with the 40’s widely used before the full clay brick or full-height aluminum brick blast furnace bottom often occur in blast furnace bottom and furnace Cylinder breakage accident, in severe cases were forced to shutdown furnace overhaul, thereby reducing the life of such aluminosilicate furnace bottom. A survey of the bottom life of aluminosilicate materials for most blast furnaces in China over 300 meters in 1963 showed that the average life expectancy of the blast furnace generation was only 4 years and 9 months. WISCO No.2 blast furnace (1436m ~ 3) The first generation of full-height aluminum brick bottom burned through accident occurred, the generation of life is only 5 years and 7 months. Of course, all clay brick furnace floor occasionally have longevity. Some people abroad in the longer life of the clay brick hearth and furnace overhaul demolition, the
