In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a vacuum insertion tube steel courage, includes the steel courage body, the inner chamber of steel courage body passes through welded mode fixedly connected with annular ring, the inner chamber of steel courage body is polytype wedge, welded connection has gas box room and anchor assembly respectively through the mode that argon arc welded on the surface of steel courage body, the bottom intercommunication of gas box room has the argon gas pipeline, the argon gas pipeline is stainless steel.

Preferably, the number of the air box chambers is two, and the air box chambers are symmetrically distributed on the surface of the steel liner body.

Preferably, the anchoring pieces are arranged in a plurality and are uniformly distributed on the surface of the steel liner body.

Preferably, the bottom end of the steel liner body is communicated with a fixed cylinder.

Preferably, the surface of the fixed cylinder is fixedly connected with a support ring and a support ring from top to bottom respectively.

Preferably, the surface of the fixed cylinder is provided with a plurality of air holes which are uniformly distributed on the surface of the fixed cylinder.

Advantageous effects

The utility model provides a steel liner of a vacuum insertion tube. Compared with the prior art, the method has the following beneficial effects:

(1) this vacuum insertion pipe steel container, through the inner chamber at the steel container body through welded mode fixedly connected with annular ring, the inner chamber of steel container body is polytype angle contract, there are gas chamber room and anchor assembly on the surface of steel container body through argon arc welded mode difference welded connection, present whole air chamber box changes upper evenly distributed into, be difficult to burnt out by the molten steel, work that can be stable, thereby improve the life of insertion pipe, reduce each steelworks steelmaking cost, and steel container internal design preparation is polytype angle contract, there is stronger adduction clamping force to inside magnesium data plate brick, the not hard up of the inside magnesium chrome brick of having stopped collapses.

(2) This vacuum insertion tube steel container has the argon gas pipeline through the bottom intercommunication at the gas box room, and the argon gas pipeline is stainless steel, and special stainless steel is selected to the argon gas pipeline, according to evenly arranging, siphons away thermal advanced poling method preparation, has stopped the deformation jam of argon gas pipeline, has effectively improved the life of insertion tube.
