Device and method for baking tundish sliding nozzle

The invention relates to a device for baking a tundish sliding nozzle. The device comprises a machine body, an air inlet pipe and a hot air discharge pipe. An air inlet is formed in the upper side of the machine body and extends into the machine body. The air inlet is used for being connected with the sliding nozzle and guiding hot air in the tundish into the machine body. The hot air discharging pipe is connected to the side face of the machine body, communicates with the interior of the machine body and communicates with the air inlet. And one end of the air inlet pipe is communicated with the hot air discharge pipe and is used for introducing compressed air into the hot air discharge pipe. In addition, the flowing direction of the compressed air discharged into the hot air discharging pipe by the air inlet pipe is the direction deviating from the machine body. According to the device for baking the sliding nozzle of the tundish, hot air in the tundish is guided through the compressed air to bake the slidin
