摘　　要：采用回旋区经验公式对850~5500m^(3)高炉生产数据进行了计算分析,探讨了回旋区形状的变化规律及对综合指标的影响,确定高炉合理回旋区面积占比的区间。通过数据分析得出,随着高炉容积的增大,回旋区面积占比逐渐减小1000m^(3)级高炉回旋区面积占比最大,3000m^(3)级以上高炉回旋区面积占比在同一区间内。不同容积的高炉回旋区面积占比对利用系数、燃料比的影响规律不同,使高炉综合指标最优的合理回旋区面积占比为:1000m^(3)级高炉应大于0.78;2000m^(3)级高炉为0.59~0.61;3000m^(3)级高炉为0.51~0.52。The production data of 850-5500m^(3) BFs is calculated and analyzed via the empirical formula of the tuyere race-ways,followed by a discussion on the change law of the raceway shape and its influence on the comprehensive indexes,so as to determine a reasonable ratio of the raceway area and the hearth area.The data analysis indicates that the ratio of raceway area decreases gradually as the furnace volume increases:the said ratio of BFs around 1000m^(3) is the highest,while that of BFs over 3000m^(3) varies in the same range.For different sizes of BFs,the influence rule of raceway area ratio on BF produc-tivity and fuel rate is different,and the ratio which enables to achieve the best comprehensive BF indexes is also different.It is over 0.78 for 1000^(3) BFs,0.59-0.61 for 2000m^(3) BFs,0.51-0.52 for 3000m^(3) BFs.
