摘要:
高炉热风炉为炼铁核心配套设备，炉内正压气密恶劣工况下，传统接触式热电偶易出现精度衰减、损耗快、响应滞后、炉体气密性破坏、高温气体泄漏等问题，难以满足智能化生产与安全运行需求。该文采用仿热电偶安装形式、全密封结构黑体测温技术，在保持与传统热电偶一致安装方式的基础上，实现超工况等级密封，彻底解决正压泄漏难题。以江苏沙钢2#正压气密型高炉热风炉为例开展应用测试，结果显示：该技术测量偏差±10 ℃ 以内，响应时间 ≤200 ms，密封性能远高于工况要求，可在正压气密环境下实现长期稳定高精度测温，性能显著优于传统热电偶，为正压热风炉安全高效运行提供可靠支撑。
Abstract:
Hot blast stove is a core supporting equipment for ironmaking. Under the harsh working condition of positive pressure and airtightness in the furnace, traditional contact thermocouples are prone to problems such as accuracy attenuation, rapid loss, response lag, damage to furnace airtightness, and high - temperature gas leakage, which are difficult to meet the requirements of intelligent production and safe operation. This paper adopts a blackbody temperature measurement technology with thermocouple - simulated installation form and fully sealed structure, which maintains the same installation mode as traditional thermocouples and realizes sealing performance exceeding working condition requirements, completely solving the problem of positive pressure leakage. Taking No.2 positive pressure airtight blast furnace hot blast stove of Jiangsu Shagang as an example, the application test is carried out. The results show that the measurement deviation of this technology is within ±10 ℃, the response time is ≤200 ms, the sealing performance is much higher than the working condition requirements, and it can realize long - term stable high - precision temperature measurement in positive pressure airtight environment. Its performance is significantly better than traditional thermocouples, providing reliable support for the safe and efficient operation of positive pressure hot blast stoves.
