Air inducing device for baking of tundish

The utility model provides an air inducing device for baking of a tundish, comprising a top tray, a gas flue and an injecting tube; the arced gas flue in the middle of the tundish divides into a vertical stage and a horizontal stage, an injecting tube connected with an compressed air duct is inserted along the arc top of the horizontal stage, the top tray is disposed at the upper end of the gas flue vertical stage, and is connected with a fire leading brick at the bottom of the tundish. After a butt joint of the top tray and the fire leading brick and a butt joint of the injecting tube and the compressed air, a compressed air switch is opened and a top baking cover is ignited, then the baking of the tundish can be performed. Since an air inducing device is increased, a high-temperature gas flow through a stopper rod and an upper water opening is increased, baking effect at the head of the stopper ord and the upper water opening is improved, phenomenon of local cold steel and liquid fluctuation is prevented, s
