摘要

近年国内外多座高炉面临着炉缸侵蚀加剧的问题甚至发生了炉缸烧穿事故,炉缸寿命已成为现代高炉安全高效生产的限制性环节,但目前由于缺乏系统和量化地研究,炉缸安全预警机制尚未明确。笔者依据对不同容积、结构及耐材选择的多座高炉炉缸进行的传热学计算、热负荷及侵蚀监测,比较分析了不同类型炉缸的热负荷及侵蚀特点,对炉缸监测的一次检测元件、软件模型、评判标准、预警方法进行了探讨,提出了现代高炉炉缸安全预警机制建议。

Abstract

Lots of blast furnaces (BFs) recently face the problem of hearth severe erosion even burnt out accidents. The campaign life of hearth has become the limiting factor for safe and high efficiency production of modern BFs. However, the early warning mechanism of hearth has not been clear due to the lack of system research. Based on the heat transfer calculations, heat load and erosion monitoring for various BF hearths with different volume, structure and refractory, the features of heat load and erosion for different kind hearth were compared and analyzed. The primary detecting elements, software models, evaluating standards and warning methods were discussed. The early warning mechanism of modern BF hearth was proposed.
