The invention provides a self-adjusting argon blowing connector. The self-adjusting argon blowing connector can solve the problems of weak sealing and argon leakage caused by inclination of the end face of an upper connector. The self-adjusting argon blowing connector comprises an upper connector body and a lower connector body; the lower connector body comprises a connector body and a spring, the connector body comprises a press-fitting part and a tubular part arranged in the middle of the bottom of the press-fitting part, a lower argon channel penetrating through the press-fitting part is formed in the tubular part, and a sealing ring arranged around the lower argon channel is mounted at the top of the press-fitting part; and a spring is arranged outside the tubular part in sleeving mode, and the upper end of the spring abuts against the press-fitting part. The self-adjusting argon blowing connector is characterized in that the lower connector further comprises a spring seat and an aligning block, a seat body of the spring seat abuts against the lower end of the spring, the seat body is provided with a lower guide sleeve extending upwards, and the press-fitting part is provided with an upper guide sleeve extending upwards; and the lower guide sleeve and the upper guide sleeve are connected in a sleeved mode and limited through a vertical limiting structure, and the lower portion of the seat body is matched with the aligning block through an arc face.
Description
technical field [0001] The invention relates to the field of auxiliary equipment in the steelmaking production process, in particular to a self-adjusting argon blowing joint. Background technique [0002] During the molten steel transfer process under the furnace, the molten steel tank needs to blow argon to the molten steel to achieve the effect of stirring the molten steel. Generally, argon blowing devices are usually installed on the transfer equipment under the furnace, such as molten steel tank cars and ladle turrets. When the molten steel It is necessary to connect the argon pipeline of the molten steel tank with the argon blowing device on the transfer equipment when the tank is dropped, and the automatic argon blowing joint is generally used for connection. The existing automatic argon blowing joint includes an upper joint and a lower joint. The upper joint is installed on the seat of the tank on the side of the molten steel tank, and the lower joint is installed on ...
