Description

Technical Field

[0001] The utility model relates to the technical field of ladle argon blowing, in particular to an argon gas protection device for a ladle. Background Art

[0002] The argon gas is blown through the argon blowing device on the surface of the ladle car. The ladle bottom blowing gas control system design at the waiting station behind the converter adopts nitrogen and box gas as two media to automatically switch for bottom blowing stirring and gas washing. Two independent bottom blowing ventilation elements are used at the bottom of the ladle. The ladle bottom blowing control system design meets the requirements of bottom blowing stirring and gas use of the molten steel ladle.

[0003] For a ladle argon protection device used when the ladle is blown and connected, the current ladle bottom blowing docking method is manual docking. After the ladle is seated, the workers need to climb onto the ladle car and approach the ladle filled with molten steel to perform manual docking operations. The docking process takes a long time and it is dangerous for the workers to run up and down. Once abnormal conditions such as the ladle tipping over occur, there are major safety hazards, which can easily cause burns and falls to people.

[0004] For this purpose, we propose a ladle argon protection device. Utility Model Content

[0026] Working principle: When argon gas is needed to be transported and supplied, the second argon ball valve 9 is connected to the connected transport pipe, and the argon gas is transported into the transport gas valve 4 through the pressure argon gas source 3 of the argon supply station, and then enters the argon blowing device 2 on the top of the ladle car body 1 through the first argon ball valve 6. The argon gas is transported into the one-way valve 8 through the argon blowing device 2. The one-way valve 8 flows the argon gas into the second argon ball valve 9 for subsequent transportation and argon blowing work.
