It is well known that a "hanging" in a blast furnace makes the productivity of blast furnace lower. However, the growth behavior and the cause of hanging have not been fully ascertained, excepting only some assumptions. Therefore, an experimental apparatus was devised, in which the reducing gas passed through the iron ore bed the same as in a blast furnace. With this experimental apparatus, the phenomenon similar to the hanging in the shaft of blast furnace was observed. Then, studies were made on the relation between the gas analysis, the iron ore size, the rate of carbon deposition and the variation of bed permeability. Consequently, it was found that the tendency to occur the hanging varied with the change in gas composition, ore size and ore qualities. It was also confirmed that the hanging was closely connected with the rate of carbon deposition.
