The invention discloses a steel ladle bottom argon blowing gas flow control device and control method, and solves the technical problem that existing steel ladle bottom argon blowing gas flow cannot be controlled automatically and accurately. The steel ladle bottom argon blowing gas flow control device comprises a camera, a steel ladle, an air brick, an image processing and control center server and an argon gas flow control valve. The camera is arranged above a mouth of the steel ladle; the camera is connected with the image processing and control center server through a cable; the image processing and control center server is connected with the argon gas flow control valve arranged on an argon gas pipeline through a cable; the input end of the argon gas flow control valve is communicatedwith an argon gas source through the argon gas pipeline; the output end of the argon gas flow control valve is communicated with the air brick through the argon gas pipeline; and the air brick is arranged on the bottom portion of the steel ladle. The control device realizes automatic and accurate control of steel ladle bottom argon blowing gas flow, and improves quality of liquid steel.
