Abstract

PURPOSE:An operation method of blast furnace with which at the feeding of raw materials the flowing of the pellets onto the center part of the furnace and the unbalanced heaping are prevented, an uniform and stable layer of the pellets can be formed, and the coke ratio can be lowered, by improving remarkably the contact friction resistance and the angle of repose of the pellets themselves.
