A detection wave from a transmitting/receiving means is guided to the interior of a shaft furnace via an antenna and a reflecting plate, and when a reflected wave from the surface of a charging material is reflected by the reflecting plate and received by the transmitting/receiving means, the reflecting plate is rotated together with the antenna, or the reflecting plate is rotated additionally, and the surface profile of the charging material is measured by scanning the surface of the charging material in a linear manner or a dimensional manner during the turning of a chute or for each prescribed turn of the chute. A deposition profile is obtained on the basis of this surface profile and is compared to a predetermined theoretical deposition profile, and the chute is controlled so as to correct the error with respect to the theoretical deposition profile, after which new charging material is introduced. The shaft furnace is operated using this charging method. |
