摘要
为了提高高炉温度在线监测能力,通过双路解调方案构建分布式拉曼光纤温度测试系统,采用外部触发方式,实现相互协调的工作状态。温度测试结果表明:对常温状态下的系统各通道分别进行距离为10 m范围的温度精度达到±1℃,保持良好的稳定性。该系统在高低温测试范围内具备较优的响应性能,能够满足高炉测温要求。该研究能够有效地降低高炉燃烧器温度控制器受到经验因素的影响,也能够更加稳定调节燃烧器温度,最终实现高炉温度智能参数的控制功能。
In order to improve the on-line monitoring ability of blast furnace temperature,a distributed Raman fiber temperature test system is constructed by means of dual-channel demodulation scheme.The temperature test results show that the temperature accuracy reaches±1℃when the distance of each channel of the system is 10 m respectively under normal temperature condition,and good stability is maintained.The system has better response performance in the range of high and low temperature test and can meet the requirements of blast furnace temperature measurement.The research can effectively reduce the influence of experience factors on the temperature controller of blast furnace burner,and also can adjust the burner temperature more stably,and finally realize the control function of the intelligent parameter of blast furnace temperature.
