摘　　要：高炉炉缸炉底耐材寿命是影响高炉一代炉役寿命的限制性环节,及时了解炉缸炉底的侵蚀情况并作出针对性调整措施至关重要。基于传热学、数值模拟、遗传算法等研究方法,结合炉缸炉底侵蚀、结厚的形成机理,利用炉缸炉底热电偶在线采集的温度数据,开发了沙钢3号高炉炉缸炉底侵蚀结厚智能监测系统。该系统还原了沙钢3号高炉整个炉缸炉底区域的温度场分布,实现了侵蚀结厚的动态模拟。此外,相比以往模型,本模型改进了人机交互方式,使炉缸炉底侵蚀结厚模拟结果以更加直观的图像与视频方式予以展示,从而使炼铁工作者更容易掌握炉缸炉底侵蚀现状及变化趋势。The life of blast furnace hearth and bottom refractory material is a restrictive link that affects the service life of the first generation of blast furnace.It is very important to know the corrosion situation of the hearth and bottom and make targeted adjustment measures in time.Based on the research methods of heat transfer,numerical simulation,genetic algorithm,combined with the formation mechanism of erosion and freezing of hearth and bottom,and using the temperature data collected online by the hearth and bottom thermocouple,intelligent monitoring system for erosion and freezing of hearth and bottom of No.3 blast furnace in Shasteel is developed.The system restores the temperature field distribution of the entire hearth and bottom area of Shasteel No.3 blast furnace,and realizes the dynamic simulation of erosion and freezing.In addition,compared with previous models,this model improves the human-computer interaction mode,so that the simulation results are displayed in a more intuitive way of images and videos,which makes it easier for iron smelters to grasp the current status and changing trends of hearth and bottom erosion.
