In the figure, (20) is a fitting having an inner cavity portion having a shape substantially similar to that of the frustoconical packing material (11). A large number of suction / blowing holes (21) are provided on the inner peripheral surface, and these suction / blowing holes (21) communicate with the suction mechanism and the compressed air source via the communication part (22) and the hose (23). There is.

The means for mounting the conical packing material (11) on the insert nozzle (24) using the mounting tool (20) of the above mechanism will be described below.

The conical packing material (11) is fitted into the inner cavity of the mounting tool (20), and the packing material (11) is held by suction. On the other hand, the insert nozzle (24) is supported by an insert nozzle support tool (26) that can be mounted on, for example, a robot hand, and can support the insert nozzle (24) by an internal cylinder (25).

The insert nozzle (24) is fitted into the inner cavity of the conical refractory packing material (11) held by the mounting tool (20) by the operation of the supporting tool (26) by the robot hand or the like, and the insert is inserted. The refractory packing material (11) is adhered to the outer periphery of the nozzle (24). At this time, if necessary, a refractory adhesive may be used on the joint surface.

As described above, the insert nozzle in which the outer peripheral surface is covered with the refractory packing materials (2) and (11) can be externally attached and fixed to the nozzle receiving brick at the bottom of the molten metal container by an automated mechanism such as a robot.
