我国初轧厂均热炉,一般都使用硅砖炉墙、粘土砖炉口。由于用小块砖砌筑,灰缝多、整体性差和材质本身的缺欠,均热炉炉衬寿命平均为一年,好者为一年半左右。炉衬寿命短,已经不能满足初轧厂某些生产指标要求。为解决高产长寿炉衬问题,近年来有关单位对不定形耐火材料,开 China’s early rolling mill are hot furnace, the general use of silica brick furnace wall, clay brick furnace mouth. Due to the use of small brick masonry, more cracks, poor overall and the lack of material itself, average furnace lining life of an average of one year, good for about a year and a half. Furnace lining life is short, can not meet some of the early rolling mill production targets. In order to solve the problem of high yield longevity lining, in recent years the relevant units of amorphous refractory material, open
