METHOD FOR CHARGING AND DEPOSITING CHARGING MATERIAL IN SHAFT FURNACE CHARGING MATERIAL SURFACE DETECTION DEVICE AND METHOD FOR OPERATING SHAFT FURNACE

摘要

The detection wave from the transmission / reception means is led into the blast furnace through the antenna and the reflection plate, and when the reflection wave due to the surface of the charge is reflected by the reflection plate and received by the transmission / reception means, the reflection plate is rotated together with the antenna, The surface of the charge is linearly or surface-scanned during the turn of the shooter or at every predetermined turn to measure the surface profile of the charge. Based on this surface profile, a sediment profile is found, compared with a previously obtained theoretical sediment profile, and a new charge is charged by controlling the shooter to correct the error with the theoretical deposition profile. The blast furnace is operated using this charging method.
