一、前言掌握准确的炉料落下轨迹是高炉上部调剂操作、装料装置设计以及布料理论分析和计算的基本依据。上部调剂的重要内容之一就是通过控制和调节料流轨迹即炉料落点、堆尖形成位置和各部分的料层厚度,来满足冶炼过程对矿焦比的分布和煤气分布的要求。现代化大型高炉采用变径炉喉和无钟布料等新技术的成功也进一步
I. Foreword To master the exact trajectory of charging material is the basic basis for the adjustment operation of the upper part of the blast furnace, the design of the charging device and the theoretical analysis and calculation of the cloth. One of the important contents of the upper adjustment is to meet the requirements of the smelting process on the distribution of the coke ratio and the gas distribution by controlling and adjusting the flow trajectory, namely the charging point, the formation position of the pile tip and the material thickness of each part. The success of modern large-scale blast furnaces using new technologies such as variable-diameter furnace throat and bell-less fabrications goes further
