摘　　要：基于在线黑体空腔理论的研究成果,设计了一种新型黑体空腔式钢水连续测温传感器,解决了钢水连续测温这一难题。介绍了传感器的结构原理,并对机理进行了详细的分析。实验结果表明,测量误差≤±3℃,测温管寿命可达20～40h,测温成本与现行的快速热电偶实际消耗相当或略低,具有较强实用性,现已成功应用于28家钢铁公司。Based on theoretic research of on-line blackbody radiation, a new sensor of blackbody cavity-based continuous temperature measurement for liquid steel is designed, the structure and principle of the sensor are detailed as well. The test results exhibit a measuring error of less than or equal to ±3°C, a measuring tube service life of 20 to 40 hours and lower consumed costs corresponding to that of quick-thermocouple. It has been used in 28 steel works.
