摘要
针对当前高炉长寿管理滞后和针对性差的现状,将高炉炉缸工艺设计、传热学理论与高炉操作工艺相结合,开发了一套炉缸长寿智能管理系统。除传统炉缸侵蚀模型的炭砖侵蚀曲线计算功能以外,还具有凝铁层在线监控、炉缸气隙判断、凝铁层减薄原因诊断和给出针对性改善建议4项核心功能。该系统全部模块均进行在线监测、计算、诊断和建议,其关键目的不是计算侵蚀曲线,而是防止炉缸侵蚀的发生,可为做好高炉的长寿管理、延长高炉寿命起到重要作用。
Corresponding to the current situation of hysteretic nature and poor pertinency of blast furnace longevity management,combined with the process design of blast furnace hearth,heat transfer theory and operation of blast furnace process,a set of hearth longevity intelligent management system was developed.In addition to calculation function of carbon brick erosion curve by conventional hearth erosion model,it had another 4core functions including the monitoring for the iron freeze layer online,the judgment for the hearth air gap,the diagnosis of the iron freeze layer,and the corresponding improvement suggestions.All monitoring,calculation,diagnosis and suggestions were online in the system.Its key purpose was not to calculate the erosion curve,but to prevent the occurrence of hearth erosion,which could give excellent help to blast furnace longevity management,and play an important role in extending life of a blast furnace.
