Description
Technical field
The invention belongs to steelmaking technical fields, more specifically to integral-rotation sublance.
Background technique
Sublance is one of the most important application of modern converter automatic Steelmaking technology development, by pair in convertor steelmaking process
Rifle is accurate, real-time measurement data adjusts oxygen gun blowing amount and flux additive amount and judges blowing end point etc..Sublance
Using being converter is quickly tapped and good steel is achieved out guarantee.In today that steel-smelting technology and equipment are constantly progressive, sublance
Have become indispensable one of steelmaking equipment.
Sublance body will be inserted directly into inside the converter of high temperature in sublance measurement process, by hyperthermia radiation heat and melting spray
The influence of object is splashed, therefore sublance body is cooled down using cooling water.Sublance body is set with by three layers of seamless steel pipe, outer layer
Circumferential weld is used for sublance cooling water intake tunnel between pipe and middle tube, and circumferential weld is used for sublance cooling water between middle tube and central tube
Backwater channel, central tube are used for sublance signal cable channel.It is well known that sublance body is by radiating heat affecting in Converter,
Often there is buckling phenomenon in gun body.And it is this bending be all towards oxygen rifle lateral bend, therefore usual way be manually periodically
Rotation sublance is bent to cope with.Sublance outer tube sets a rotary joint, clamps pair by a Chain wrench when needing to rotate
Rifle outer tube manually pulls the rotation that Chain wrench realizes sublance outer tube.I.e. so-called rotation sublance is only to rotate outside sublance
Layer pipe, central tube and middle tube do not rotate.This mode realizes that sublance rotation has the following problems: sublance body is by three layers of nothing
Seam steel pipe is set with, and some locating pieces are arranged between every layer of seamless steel pipe, once sublance is bent, easily causes locating piece and outer layer
It is very big to can be manually rotated sublance resistance, or even can not rotate for pipe asphyxia by external pressure on the chest and abdomen.Only rotate outer tube, i.e. outer tube and middle tube, inner tube
There are suitable rotary motion, pipette tips and the effective O-ring of internal layer are sealed, and relative rotation will affect O-ring sealing, and rotation easily causes close
Envelope infiltration, and by the detecting elements such as cable and connector in inside tube, once it gets wet or moist can all cause can't detect
Signal or signal detection are wrong, this is the problem of outer tube is individually rotated up to.Also because of problem thus, so many steel mills all put
It abandons and uses sublance outer tube rotation function, therefore can not also solve or mitigate sublance bending, while also resulting in sublance and using the longevity
It orders short.
Summary of the invention
Present invention aim to address problem of the existing technology, it is convenient to provide a kind of rotation process, effectively solve or
Person mitigates sublance warp tendency, extends sublance service life, reduces equipment failure rate, meets the entirety of converter safety and stability production
Rotate sublance.
To achieve the goals above, the technical scheme adopted by the invention is as follows: provided this integral-rotation sublance, including
Gun body, the gun body include central tube, and the middle tube outside central tube, are externally provided with outer tube in the middle tube, described
One end of gun body be inserted into converter in pipette tips end, it is characterised in that: the upper end of the gun body be equipped with water inlet rotary joint and
Return water rotary joint, the gun body can be rotated around the water inlet rotary joint and return water rotary joint, the water inlet rotary joint
It is equipped with water inlet, the water inlet is connected to cavity between the outer tube and the middle tube, on the return water rotary joint
Equipped with water return outlet, the water return outlet is connected to cavity between the middle tube and the central tube；Drive is additionally provided in the gun body
Its rotation drive device rotated.
To keep above-mentioned technical proposal more detailed and specific, the present invention also provides optimization technique sides further below
Case, to obtain satisfied practical function:
The rotation drive device includes the pivoting support being connected in the gun body, further includes driving the pivoting support
The drive motor of rotation.
The output end connection driving worm screw of the drive motor, the driving worm screw nibble with the gear being equipped on pivoting support
Close transmission.
It is equipped with mounting base positioned at the upper end of the rotation drive device in the gun body, the rotation drive device is mounted on
In the mounting base.
The rotation drive device lower end is equipped with fixing seat, and when sublance is installed, it is small that the fixing seat is fixedly connected on lifting
Che Shang.
