摘　　要：首钢股份3号高炉进行了持续18天高球团矿配比冶炼试验,最高球团矿比例达到38%,并持续了6天。针对球团矿比例由27%提高到38%后,高炉煤气流分布、Z值、IF值、软水温差、透气性指数等操作参数的变化,通过高炉基本操作制度的调整,实现了球团矿在炉内布料平台的准确控制,改善煤气流分布,保证了高炉稳定顺行。球团矿比例提高后,燃料比略有所上升。A test smelting with high rate of pellet is carried out in No.3 BF of Shougang Co.,Ltd.for 18 days.The furnace even operates with highest rate of pellet up to 38%for 6 days.According to the operation parameters,such as BF gas flow distribution,Z value,W value,soft water differential temperature,permeability indicators,etc.which vary as the rate of pellets increase from 27%to 38%,we adjust the basic operating system of the furnace.As a result,the pellet distribution gets accurately controlled regarding the distribution platform inside the furnace,the gas flow distribution is improved,and furnace achieves stable and smooth running.
