Abstract

The slag crust thickness on the hot surface of the copper cooling staves in the high thermal load areas of a blast furnace is crucial for the safe operation and long campaign of the blast furnace. In this study, a heat transfer model for the slag crust and the copper cooling staves in a blast furnace is established. The temperature distribution in the slag crust and copper cooling staves is calculated and the temperature variation in the copper cooling stave with the change of slag crust thickness is also studied. The temperature measurement data of the copper cooling staves are fitted with the corresponding slag crust thicknesses, and an online model for calculating the slag crust thickness is established. The slag crust thickness is displayed in the form of a contour map by unfolding the slag crust and the copper cooling staves along the circumferential direction of blast furnace, by which the visualization of slag crust thickness distribution and the variation in slag crust thickness with time can be achieved. This online visualization model can help operators accurately judge the locations where the slag crust thickness fluctuates severely, and take timely and effective measures to guarantee the normal operation condition.

高炉铜棒渣壳厚度在线可视化模型

高炉高热负荷区铜冷却板热表面的渣壳厚度对高炉的安全运行和长期运行至关重要。本研究建立了高炉内渣壳和铜冷却条的传热模型。计算了渣壳和铜冷却条的温度分布，并研究了铜冷却条的温度随渣壳厚度变化的情况。将铜冷却条的温度测量数据与相应的渣壳厚度进行拟合，建立了在线计算渣壳厚度的模型。通过沿高炉圆周方向展开渣壳和铜冷却棒，以等高线图的形式显示渣壳厚度，从而实现渣壳厚度分布和渣壳厚度随时间变化的可视化。这种在线可视化模型可以帮助操作人员准确判断渣壳厚度波动严重的位置，并及时采取有效措施保证正常的操作状态。
