ABSTRACT:
An apparatus for determining the charging profile on the charging surface of a shaft furnace is presented. The apparatus consists of a plurality of level probes, each probe including a weight which is suspended vertically above the charging surface on the first end of a cable which projects from a supporting arm. The second end of each of these cables, in turn, is connected outside the furnace to respective winding drums, each drum being controlled by a driving device which raises or lowers the probe connected to the drum. This invention also consists of a monitoring device for measuring the unwinding of the cable from the drum and the descent of the probe onto the charging surface as well as a method of replacing an individual probe and its cable from outside the shaft furnace.
