直至目前为止,人们对炉温的判断都是以生铁含矽为标志。从1963年起,我们开始点测铁水温度,发现同样的生铁含矽有很不相同的铁水温度。为了找出铁水温度与高炉工作状况的关系,1965年4月份开始进行了连续测量铁水温度试验。试验得出,铁水温度曲线变化,能反映炉缸工作状况,高炉顺行情况,比生铁含矽更灵敏的反映炉温变化动 Until now, people’s judgment of the furnace temperature is based on pig iron silicon. Starting in 1963, we started to measure the hot metal temperature and found that the same pig iron silicon had a very different hot metal temperature. In order to find out the relationship between the hot metal temperature and blast furnace working conditions, a continuous measurement of hot metal temperature was carried out in April 1965. The experiment shows that the change of temperature curve of molten iron can reflect the working condition of the hearth and the blast furnace goes on-line, reflecting the change of furnace temperature more sensitively than that of pig iron silicon
