一,一般概念 高炉炉料的空隙度,对料柱透气性和炉况顺行的影响极大。国内外高炉工作者对高炉炉料空隙度的研究始终是十分重视的。 高炉就其实质而言,是一个逆流式层状充填料化学反应器(如图1)。高炉冶炼过程中,风口前热风与燃料燃烧产生的高温煤气流,在上升过程中与不断下降的散料状料柱相接触,使两个逆流流股间进行着动量传 First, the general concept of blast furnace charge porosity, permeability of the column material and the furnace condition of the great impact. Blast furnace workers at home and abroad on the blast furnace charge porosity has always been very important. In essence, the blast furnace is a countercurrent layered charge chemical reactor (Figure 1). In the process of blast furnace smelting, the hot gas flow generated by the hot air in front of the tuyere and the combustion of the fuel comes into contact with the falling bulk material column during the ascending process, so that the momentum flows between the two countercurrent streams
