近年来,国外广泛地采用炉喉挡料板,无钟炉顶的装料设备也日益增多,这就极大地丰富了高炉上部调剂的内容和措施.然而,以目前鞍钢的状况而言,钟式装料设备仍然是唯一的装料设备.尽管装料设备种类繁多,其控制煤气流分布都是以下列几种作用因素,改变高炉径向的焦炭负荷分布来实现的,即:1. 炉料在料面上的堆尖位置;2. 炉料在料面上的堆角;3. 炉料对料面的冲击作用;4. 炉料性质差异所引起的效应.高炉冶炼工作者,就是以上述因素,控制炉料的分布状态,以达到充分利用煤气能量的目的.本文将以简单的力学关系分述上述有关影响布料的因素.
In recent years, extensive use of furnace throat block board, bell-less top loading equipment is also increasing, which greatly enriched the contents of the upper part of the blast furnace and measures.However, the current status of Angang, the bell Although the charging equipment is still the only charging device, despite the wide variety of charging equipment, the control of gas flow distribution is achieved by varying the coke load distribution in the radial direction of the blast furnace by the following several factors, namely: The heap tip position on the surface of the material; 2. The heap angle of the charge on the surface of the material; 3. The impact of the charge on the surface of the material; 4. The effect caused by the difference of the charge characteristics. The blast furnace smelting workers are based on the above factors, Control the distribution of charge in order to achieve the purpose of making full use of gas energy.This article will be a simple mechanical relationship between the above-mentioned factors that affect the fabric.
