摘要： PROBLEM TO BE SOLVED: To develop a technology for performing a stable operation of a blast furnace by correctly grasping gas and liquid permeability in a lower part of a blast furnace under operation.
SOLUTION: An assumed drop of the blowing pressure at a lower part of a blast furnace 1 under operation is obtained, and the grain size of filled stuff in the lower part of the blast furnace is estimated using the assumed drop. The assumed drop of the blowing pressure in the lower part of the blast furnace under stable operation is obtained in advance, and the grain size of filled stuff in the lower part in that condition is estimated by using both assumed drops. The ratio of the grain size of the filled stuff in the blast furnace under operation to the grain size of the filled stuff under stable operation is used as an index of the operational stability of the blast furnace. In a method for obtaining the assumed drop, the assumed blowing pressure P
b ' on the tuyere axis 4 is obtained by using the pressure in the vicinity of the inner wall of the furnace at two or more points belonging to a tapered part 10 above the tuyere, and the differential pressure between P
b ' and the measured pressure P
min at the highest position among the two or more pressures is defined as the assumed drop. The average grain size of the filled stuff in the lower part is obtained from the assumed drop by using the Ergun formula.

摘要： PROBLEM TO BE SOLVED: To provide a method for charging a raw material into a blast furnace so that fine grains in the raw material may not be charged onto the central part or peripheral part of the furnace and deposit there, even when the grain sizes of the raw material discharged from a hopper at the furnace top fluctuate.
SOLUTION: When charging one batch of the raw material 5 into the blast furnace with the use of a slewing chute 1 in a bell-less type charging device provided at the furnace top, this charging method comprises the steps of: adjusting a tilt angle θ of the slewing chute so that the tip of the slewing chute directs at a central position (S) in a radially middle part of the blast furnace, and starting charging of the raw material; then, continually charging the raw material 5 gradually toward the furnace center while changing the tilt angle so that the tip of the slewing chute sequentially directs at the central part of the furnace; subsequently, charging the raw material 5 gradually toward the peripheral part of the furnace while changing the tilt angle so that the tip of the slewing chute directs at the periphery of the furnace; and changing the tilt angle so that the tip of the slewing chute directs at the furnace center again, and finishing the charge at a central position (F) in the middle part.

摘要翻译：要解决的问题：提供一种将原料装入高炉的方法，使得原料中的细晶粒可能不被装入炉的中心部分或周边部分并沉积在炉中，即使炉顶料斗排出的原料粒度波动。
解决方案：在炉顶设置的无铃式充电装置中，通过使用回转斜槽1将一批原料5装入高炉中时，该充电方法包括以下步骤：回转斜槽的倾斜角度θ，使得回转斜槽的尖端在高炉的径向中间部分的中心位置（S）处引导，并且开始对原料充电; 然后，在改变倾斜角度的同时，将原材料5逐渐向炉中心充满，使得回转斜槽的尖端依次引导到炉的中心部分; 随后，在改变倾斜角度的同时使原料5逐渐向炉的周边部分充电，使得回转斜槽的尖端在炉的周边引导; 并且改变倾斜角度使得回转滑槽的尖端再次引导到炉中心，并且在中间部分的中心位置（F）处完成充电。版权所有（C）2008，JPO＆INPIT
