高炉炉缸活性量化计算模型的开发与实践

Development and practice of quantitative calculation models of blast furnace hearth activity

在对传统炉缸活性计算模型研究分析的基础上,针对本钢新1号高炉等国内大型高炉操作惯性大的特点,提出了两个炉缸活性量化计算模型,即炉缸工作活跃指数优化模型和炉缸活跃性指数优化模型。通过采集与处理本钢新1号高炉生产数据以及编程技术完成了模型的离线计算,并成功应用于本钢新1号高炉的生产中,实现了对炉缸活性的量化计算。实践证明,模型的计算结果可以真实地反映炉缸活性状态,有效地帮助高炉操作者及时把握炉缸活性,当炉缸活性下降或失常时,可以在第一时间发现并尽早进行操作干预,将炉缸不活抑制在萌芽状态,及时地避免了因炉缸活性恶化所造成的一切损失,从而在维护炉缸活性、保持高炉长期稳定顺行等方面发挥重要作用。

According to the big inertia of new No.1 BF and in BX steel and other modern huge blast furnaces,two hearth activity quantitative calculation models were put forward based on the analysis and research of traditional hearth activity calculation models,which the blast furnace hearth working activity index optimization model and the blast furnace hearth activity index optimization model.The off-line calculations of the models were realized and practiced in the production of new No.1 BF in BX by the technologies of data acquisition,processing and programming,which can make hearth activity quantitative calculation come true.Practice has proven that the calculation results of the models could truly reflect the hearth activity and effectively help foremen better grasp the blast furnace hearth activity in real time.the hearth activity was becoming declining and abnormal,the foremen could find out it and make the correct operating intervention as early as possible,which could timely avoid all the losses caused by the deterioration of hearth activity.There fore,the models were playing important roles in the aspects of keeping blast furnace good hearth activity and long-term stability.
