ABSTRACT:
The servicing of clay guns used in plugging the pouring holes of blast furnaces is facilitated by providing for the access to the sealant receiving cylinders of such clay guns through the front end thereof and without disassembling the clay gun from their actuators. Ease of access results from providing a cylinder front end extension which may easily be removed from axial alignment with the cylinder and which receives and accommodates at least that portion of the clay gun ejector piston which bears sealing rings when the piston has been extended to its limit of travel.
