摘要
铜冷却壁要长期安全地工作,在其热面必须有渣皮覆盖；同时铜冷却壁的高导热能力很可能导致炉墙结瘤,因此,对炉墙监控有利于高炉长寿,同时也是实现长寿和高效的结合点。结合首钢高炉的现场实际情况,采用传热学反问题的方法,开发了铜冷却壁炉墙内型管理模型,对渣皮状况进行跟踪,从而为高炉操作提供依据和条件,有利于避免铜冷却壁裸露、炉墙结瘤等异常发生。
The hot surface of copper cooling stave need to be covered by the slag in order to allow it working safely for a long time, meanwhile, high heat transmission feature of copper cooling stave may cause skull generated on the furnace wall. The monitoring system of furnace wall will be helpful for long campaign of blast furnace and is critical for realizing high efficiency of blast furnace. The paper introduces the development of model for inner profile control of furnace wall lined with copper cooling stave based on philosophy of the inverse problem on heat transmission with purpose of wall slag tracking with respect to actual condition on site of blast furnace in Shougang Co. , this model lays basis and provide preconditions for furnace operation and effectively protects the copper cooling stave losing liner and prevents the furnace wall from skull generation.
