ABSTRACT:
To open a furnace taphole that is closed by a body of plugging material and a tapping rod the tapping rod is driven into the interior of the furnace. Because the tapping rod is driven in and not withdrawn, it is not necessary to provide a second hammer striking blows in the opposite direction, but the hammer used to drive the tapping rod into the body of plugging material is again employed.
