一、前言 测量热风炉顶温度是保护热风炉,监视热风工艺的重要手段。多年来,热风炉顶温度的测量都是采用铂铑-铂热电偶,这种测温方法在高温和振动下热偶寿命很短,且成本高、工人劳动强度大。过去,我们就热风炉顶测温专题进行过很多探索,但始终没有获得理想结果。最近一年多来,首钢总计控室与江苏海门县电子研究所合作,用红外线技术进行炉顶测温,经不懈努力,克服种种困难,终于研制成功热风炉顶红外测温装置,并成功地用于首钢十四座热风炉顶,取 First, the foreword Measuring hot stove top temperature is to protect the hot stove, hot air monitoring an important means of craft. Over the years, the temperature of the hot stove roof is measured using platinum and rhodium - platinum thermocouple, this temperature measurement method under heat and vibration thermocouple very short life expectancy, and the high cost, labor-intensive workers. In the past, we did a lot of exploration on the topic of hot stove roof temperature, but we did not get the desired result. Over the past year or so, Shougang Total Control Room and Jiangsu Haimen Electronics Research Institute, with infrared technology for roof temperature measurement, the tireless efforts to overcome all difficulties, and finally developed a hot air stove top infrared temperature measuring device and successfully used In Shougang fourteen hot stove top, take
