Abstract
The utility model relates to a joint structure of argon blowing at ladle bottom, which comprises a bottom argon blowing pipe at the bottom of a steel ladle, and an argon gas pipe joint connected with the bottom argon blowing pipe. The structure is characterized in that an angle between the argon gas pipe joint and the bottom argon blowing pipe ranges from 120 degrees to 150 degrees. The utility model has the advantages that an operating personnel can connect the argon gas pipe to the argon gas pipe joint easily without need of walking on a steel ladle vehicle on which molten steel slag is distributed, the operation is easy, and potential safety hazards caused by going up and down the steel ladle vehicle by the operating staff can be effectively avoided.
Description
Technical field
The utility model belongs to the steelmaking equipment technical field, particularly relates to a kind of steel ladle bottom argon blowing joint design.
Background technology
At present, in the iron and steel converter production process, adopt the mode of steel ladle bottom argon blowing that the molten steel in the ladle is stirred usually.When the interior ladle that molten steel arranged be transported to specify station after, need operator that tunger tube is connected to carry out Argon with tunger tube joint on the ladle, treat that the BOTTOM ARGON BLOWING operation finishes, by operator tunger tube is unloaded from the tunger tube joint again, afterwards, ladle is transported to next station.The BOTTOM ARGON BLOWING pipe that is communicated in the ladle bottom of the prior art is connected at an angle of 90 with the tunger tube joint, operator must be pedaled by staircase on the molten steel hired car that is covered with the molten steel slag and tunger tube can be connected with the tunger tube joint, operation is very inconvenient, and has serious potential safety hazard.
Summary of the invention
The utility model provides a kind of simple in structure, the steel ladle bottom argon blowing joint design that can be convenient to the installation and removal of tunger tube and tunger tube joint for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of steel ladle bottom argon blowing joint design, comprise connection the BOTTOM ARGON BLOWING pipe of ladle bottom and with the tunger tube joint of BOTTOM ARGON BLOWING pipe coupling, it is characterized in that: the angle between described tunger tube joint and the BOTTOM ARGON BLOWING pipe is 120-150 °.
Advantage and the positively effect that the utlity model has are: because the utility model adopts as above technical scheme, be that angle between tunger tube joint and the BOTTOM ARGON BLOWING pipe is 120-150 °, compare with original technology, the molten steel hired car that the steel ladle bottom argon blowing joint of this structure can make operator to climb up and be covered with the molten steel slag can be connected to tunger tube on the tunger tube joint easily, processing ease, the potential safety hazard of effectively having avoided operator to bring because of molten steel hired car up and down.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, ladle; 2, BOTTOM ARGON BLOWING pipe; 3, tunger tube joint; 4, molten steel hired car; 5, staircase.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of steel ladle bottom argon blowing joint design comprises that connection is used to carry the BOTTOM ARGON BLOWING pipe 2 of argon gas and the tunger tube joint 3 that is connected with BOTTOM ARGON BLOWING pipe 2 in ladle 1 bottom.Between described tunger tube joint 3 and the described BOTTOM ARGON BLOWING pipe 2 120-150 ° angle is arranged, in the present embodiment, the angle between tunger tube joint 3 and the BOTTOM ARGON BLOWING pipe 2 is 135 °.Above-mentioned ladle 1 is located on the molten steel hired car 4 that has staircase 5.By changing the angle between BOTTOM ARGON BLOWING pipe 2 and the tunger tube joint 3, operator only need be stood on the staircase 5 can be connected tunger tube with tunger tube joint 3, thereby realize that the molten steel in the ladle 1 is carried out Argon to be stirred, processing ease, and can eliminate the potential safety hazard that operator bring because of molten steel hired car up and down.
