The apparatus comprises a hydraulic ram (28) mounted on a movable support designed to be placed in line with the axis of the tuyere or tymp so as to bear on the furnace wall and to act on a gripper (30) composed of two telescopic members respectively displaceable relative to one another in the axial direction of the tuyere or of the tymp in order to ensure the support of the latter, said gripper (30) being axially displaceable through the action of said ram. The hydraulic ram (28) is a double-piston ram comprising a traction piston (38) acting on a pulled member (32) of the gripper (30) and a thrust piston (42) acting on a propelled member (34) of the gripper (30), and is consequently suitable far all forms of tuyeres and tymps.
