6 is a schematic view showing an operating state of the refractory cover drying apparatus according to the present invention.

First, when the cover 10 is seated on the push pin 34 to dry the cover 10, the push pin 34 descends and compresses the spring 38.

Since the pressing pin 34 is lowered, the connecting rod 36 fixed to the pressing pin 34 and the ring 30 fixed to the connecting rod 36 are lowered.

Since the ring 30 is lowered, the pin 16b of the bracket 30a inserted into the long hole 22a formed in the protruding bar 22 of the pipe 16 is lowered to rotate the pipe 16.

Since the pipe 16 is rotated, the gas inlet pipe 18 and the opening 42 formed in the pipe 16 coincide with each other so that the gas inlet pipe 18 and the ring 30 communicate with each other.

Next, the gas valve 20 is opened, the gas is introduced into the nozzle 14 through the pipe 16, and the introduced gas is ignited to dry the refractory cover 10.

When the gas is burned as described above and the refractory cover 10 is dried, the gas valve 18 is closed to cut off the supply of gas.

Next, when the refractory cover 10, which has been seated, is lifted by a lifting means such as a crane, the push pin 34 is raised by the elasticity of the spring 38.

Since the push pin 34 is raised, the connecting rod 36 fixed to the pressing pin 34 is raised, and at the same time, the ring 30 fixed to the connecting rod 36 is raised.                     

When the ring 30 is raised, the pipe 16 hinged to the ring 30 rotates.

At this time, as the pipe 16 is rotated, the nozzle 14 moves downward, and the gas inlet pipe 18 and the opening 42 of the pipe 16 do not coincide.

Therefore, since the gas inlet pipe 18 and the pipe 16 are not in communication, the gas does not leak through the pipe 16.
