一、前言加热炉是轧钢或锻钢的重要热工设备,使用温度一般在1400℃以下。过去,主要采用烧成耐火砖筑炉,平均使用寿命为1~2年;从六十年代开始,加热炉采用耐火可塑料捣打炉衬,使用寿命约为10年;七十年代后期,用粘土结合耐火浇注料代替耐火可塑
First, the foreword Heating furnace is an important thermal equipment rolling or forging steel, the use of temperature is generally below 1400 ℃. In the past, the main use of fired refractory brick building, the average life of 1 to 2 years; from the sixties onwards, the furnace using refractory plastic ramming lining, the service life of about 10 years; the late seventies, with clay Refractory castable with refractory plastic
