Steel ladle bottom argon blowing automatic butt joint device and using method thereof

Abstract

The invention relates to the technical field of ferrous metallurgy, in particular to a steel ladle bottom argon blowing automatic butt joint device and a using method thereof. The device comprises an emitter and a receiver, wherein the emitter comprises a positioning head and an external argon blowing device; the receiver comprises a receiving bowl opening and an argon interface of a steel ladle; the external argon blowing device comprises an argon pipe connector, the axis of the argon pipe connector coincides with the central axis of the positioning head, and the argon pipe connector is embedded into the positioning head and is in sliding connection with the positioning head; the inner surface of the top of the receiving bowl opening is matched with the surface of the positioning head; and the shape of the inner surface of the argon interface is matched with the shape of the outer surface of the argon pipe connector. The argon pipe connector is controlled to be connected with the inner surface of the argon interface after an electromagnet controls the positioning head to completely coincide with the top of the receiving bowl opening, so that the steel ladle bottom argon blowing automatic butt joint accuracy and the butt joint success rate are improved, the operation process is simple, the automation degree is high, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy. Specifically, the invention relates to an automatic docking device for argon blowing at the bottom of a ladle and a use method thereof. Background technique [0002] During refining in the LF refining furnace in the steelmaking process, it is necessary to use the argon blowing process at the bottom of the ladle to stir the molten steel or promote the floating of inclusions. One end of the breathable brick is connected to the argon tube, and the other end is in contact with molten steel. Since the ladle is frequently changed in the steelmaking process, it is necessary to use devices such as cranes or ladle cars to move the ladle. Therefore, the argon pipe in the ladle and the external argon source cannot be kept in a constant connection state. During the LF refining process, the external argon gas The source is connected to the argon tube in the ladle. After the LF refining is c...

Problems solved by technology

However, due to the complex process conditions on site, the large ladles are lifted by driving, and it is impossible to ensure that the ladles are positioned accurately and without deviation to the specified position. If the position of the steel ladle deviates, the central axes of the male and female components will not coincide. , will affect the docking accuracy
