基于在线激光诱导击穿光谱监控高炉流道中铁水组成的传感器研究

摘要

This paper is devoted to the description of a sensor developed at CRM in the field of the Iron and Steel Making- This sensor I based on the LIBS technique is dedicated to the continuous measurement of the composition and temperature in the blast furnace runners. The goal is to assess on-line the composition of the hot metal,mainly Fe, C, Si and Mn and its temperature. For the slag, the concentration in CaO, MgO, SiOg , A12O3 and MnO can also be determined as well as the presence of iron particles, which is an important issue for safety reasons. This sensor has been submitted to feasibility tests at the ArcelorMittal Gent blast furnace, potential advantages of using such a sensor for the process control are also presented.%本文旨在描述一种比利时冶金研究中心(CRM)研发的用于钢铁生产领域的传感器.这种以激光诱导击穿光谱(LIBS)技术为基础的传感器可以连续测量高炉流道中的化学成分和温度,其目的在于在线评估铁水的化学成分(主要包括铁,碳,硅和锰),以及其温度.这种传感器也可以测量炉渣中氧化钙、氧化镁、二氧化硅、氧化铝和氧化锰的浓度以及铁粒子的存在,这对于安全生产非常重要.这种传感器已用于比利时根特的阿塞洛米塔尔高炉的可行性测试.
