摘要：
A machine is provided for piercing a taphole for a shaft furnace for applying the piercing rod method. The machine comprises a mounting (20), a drive means (42, 44), a clamp (34) for coupling the drive means to the rod (26) during its extraction. It is characterised by a push-member (34) transmitting the said thrust force to the rear end of the rod (26) during the insertion of the rod (26) into the taphole clay and by intermediate guides (55i) surrounding the rod (26) at several places during the insertion of the rod (26) into the taphole clay. The said guides (55i) being successively placed in a position in which they do not hinder the advance of the said push-member (34, 78) on the mounting (20).
