一、前言高炉内气流运动的情况是影响高炉强化冶炼的重要因素.近代随高炉容积的大型化,炉内气体动力学已成为高炉工作者研究的主要对象.因此了解炉内气流状态的实际情况,有着重要的意义. 鞍钢高炉无论按其使用的原料或是操作方法,都有其独自特点,尤其大型高炉与国际上的同类型炉子相比较更有差别.因此探讨其冶炼过程中的气流动态和规律,借以强化高炉冶炼及改善指标是非常必要的. 1981年12月10日-24日间,在鞍钢7号高炉的不同风口发射了示踪剂,在炉身部分测气流的停留时间.首次取得炉内平均气流
I. INTRODUCTION The airflow movement in the blast furnace is an important factor that affects the blast furnace smelting.In recent years, with the enlargement of the volume of the blast furnace, the gas dynamics in the furnace has become the main object of blast furnace workers research.Therefore, to understand the actual situation of the furnace airflow , Has an important meaning.Angang Iron and Steel blast furnace regardless of the use of raw materials or operating methods, has its own characteristics, especially in large-scale blast furnace with the international comparison of the same type of furnace is more different.Therefore, to explore the gas flow in the smelting process And regularity, in order to strengthen the blast furnace smelting and improve the index is very necessary .In December 10, 1981 -24 day, in the Anshan Iron and Steel Company No. 7 blast furnace fired different trace agent, measured in the furnace body part of the flow of residence time. For the first time to obtain the average furnace airflow
