Description
Technical field
The invention belongs to the smelting of steel, relate in particular to the gas treating process a refining unit.
Background technology
It is that argon gas is blown into molten steel is stirred from ladle bottom that steel ladle bottom argon blowing is processed molten steel, evenly molten steel composition.The ladle argon-blown air feeder of current employing comprises buggy ladle and ladle, and the Argon pipe is set on buggy ladle, and an end is connected with ladle bottom, and the other end and defeated argon are hose connection; On the tension reel that establish the butterfly reel that defeated argon hose reel is established around buggy ladle and ladle car track side, when buggy ladle seesaws, rolling by butterfly reel and tension reel, unreel, the side that the tensioning all the time of defeated argon flexible pipe is suspended on buggy ladle in the air, unlikely mopping floor; The butterfly reel is that two circular steel plate and Cylindorical rods that turn up connect and compose through bolt, and defeated argon flexible pipe, around between two steel plates, is fixed by annular clamp.The defect that this device exists is: butterfly reel operating mode is severe, between two steel plates, very easily piles up slag, easy to clean not, and defeated argon flexible pipe is friction back and forth therein, easily causes wearing and tearing or pulls infringement, changes frequently, and the spare parts consumption amount is large; The butterfly reel is overhead high, the steel plate weight, and after defeated argon flexible pipe armouring, hardness is large, and is difficult fixing, changes the very inconvenience of defeated argon flexible pipe, and time and effort consuming, change once 2-3 hour consuming time, has a strong impact on production, and the serviceman stands in the lifting vehicular operation and also has potential safety hazard.
Summary of the invention
The defect that exists in order to overcome prior art, the purpose of this invention is to provide a kind of steel ladle bottom argon blowing air feeder, avoids slag to pile up, and increases the service life, and reduces and consume; Demolition, installation, easy to maintenance, laborsaving saving time, reduce stop time, is conducive to produce carry out smoothly remedial operation safety.
The steel ladle bottom argon blowing air feeder, comprise buggy ladle, ladle, Argon pipe, swivel joint, defeated argon flexible pipe and tension reel; The Argon pipe is located on buggy ladle, one end is connected with ladle bottom, the other end is connected with the swivel joint delivery port by flexible pipe, defeated argon flexible pipe one end plate twists on tension reel, the other end is connected with the swivel joint input aperture, tension reel is located at ladle car track one side top, characteristics are: buggy ladle is established gear roller support and swivel joint, swivel joint is positioned at gear roller support right side, the swivel joint delivery port connects by flexible pipe and Argon pipe, the swivel joint input aperture is communicated with defeated argon is hose connection, and gear roller support, swivel joint are positioned at the tension reel below.Buggy ladle is moved to the left from the tension reel right side, the tension reel rolling, and swivel joint is turned right, and when buggy ladle was passed through the tension reel below, gear roller support held up defeated argon flexible pipe, and buggy ladle continues to be moved to the left, and tension reel unreels, and swivel joint no longer rotates; Buggy ladle moves right from the tension reel left side, the tension reel rolling, and when buggy ladle was passed through the tension reel below, defeated argon flexible pipe broke away from gear roller support, and buggy ladle continues to move right, and tension reel unreels, and rotational shell turns left.No matter buggy ladle still moves right left, and defeated argon flexible pipe is suspended in the air all the time.During Argon, argon gas is entered in ladle molten steel by defeated argon flexible pipe, swivel joint and Argon pipe.
The present invention further improves, and described gear roller support vertically is connected with the gear roller by column, and the gear roller is round shape, and two ends are baffled, support, retrain defeated argon flexible pipe, and column is fixed on buggy ladle afterbody one side; Defeated argon flexible pipe is drawn by tension reel, by the guiding of gear roller support, with swivel joint, is connected.The purpose that arranges of gear roller support is to guarantee unlikely the mopping floor of the long distance of defeated argon flexible pipe.
The present invention further improves, described swivel joint is connected and composed by swivel joint body and base, the swivel joint body consists of stationary shaft, rotational shell, bearing, sealing and end cap, in stationary shaft, establish the two-way ar gas passage, be connected to respectively two rotational shells, each rotational shell is connected by bearing and sealing member with stationary shaft, and end cap is connected with shell, for location and fastening rotational shell; Each rotational shell and stationary shaft interface arrange tube stub, be used to connecting defeated argon flexible pipe; Base consists of base plate, side plate, cutting ferrule, and the swivel joint stationary shaft is by cutting ferrule, be fixed on base plate wearing bolt and nut, and base is fixed on buggy ladle.Side plate is established flange hole, with the flange that welds on the swivel joint stationary shaft, is connected the rotation of restricting rotation joint stationary shaft.
Compared with prior art, advantage is: novel, compact construction, reasonable, do not pile up slag, and is safe and reliable; Avoid slag to damage defeated argon flexible pipe, greatly extend work-ing life, reduces spare parts consumption, reduces frequency of maintenance; demolition, installation, easy to maintenance, laborsaving saving time, change once defeated argon flexible pipe and only use about 10 minutes; reduce stop time, be conducive to produce and carry out smoothly, also help serviceman's job safety.
