Description
Technical field
The utility model is related to a kind of burning oxygen pipe igniter.
Background technology
In steel smelting procedure, the relief port of ladle bottom is typically filled using stuffing sand.In continuous casting, ladle
Steel stream can be flow to once opening slide plate in continuous casting production from current by pass by collector nozzle of ladle.But due to drainage
The material difference of sand or liquid steel refining processing time are longer, so as to cause stuffing sand to sinter, cause ladle can not open slide plate
Automatic drainage.In order to carry out burn-through processing to the stuffing sand of sintering, generally using the one end of the rubber strip lighted to burning oxygen pipe
Ignited, reuse the burning oxygen pipe lighted and ladle is carried out to burn oxygen operation.
But, the problem of having following by the way of rubber strip is ignited, i.e. ignition operation need to carry out manually and
Point is then because burning oxygen pipe temperature is relatively low thus combustion instability, overlong time after causing continuous casting production preheating flame-out indirectly,
The resistance to material cooling of tundish is severe and is unable to maintain that normal continuous casting is opened and pours.
Utility model content
The purpose of this utility model is to solve the above problems there is provided a kind of automation for realizing igniting and improves igniting
The burning oxygen pipe igniter of reliability.
To achieve these goals, a kind of burning oxygen pipe igniter involved by the utility model, including：Burn oxygen iron pipe；
Oxygen supply portion, it supplies oxygen to the burning oxygen pipe；Magnetic valve, it is in the on-state, it is allowed to which oxygen is carried out to the burning oxygen pipe
Supply, in the closed state, forbidding to the burning oxygen pipe supply oxygen；Frequency conversion heater, it is used for one to the burning oxygen pipe
Heated at end；Temperature sensor, its temperature of one end to the burning oxygen pipe is detected；Controller, it is in the temperature
When the temperature that sensor detects heated described one end for burning oxygen pipe reaches burning-point, the magnetic valve is cut from closed mode
It is changed to open mode.
In addition, in the burning oxygen pipe igniter involved by the utility model, in addition to：Oxygen handle is burnt, it burns with described
The other end connection of oxygen pipe；Flexible pipe, its one end is connected with the burning oxygen handle, and the other end is connected with the oxygen supply portion, described
The magnetic valve is provided with flexible pipe.
A kind of burning oxygen pipe igniter according to involved by the utility model, can realize the automation and raising of igniting
Igniting reliability.
Brief description of the drawings
Fig. 1 is the burning oxygen pipe ignition device structure schematic diagram involved by embodiment of the present utility model；
Fig. 2 is the structural representation of frequency conversion heater.
Embodiment
Hereinafter, the burning oxygen pipe igniter involved by embodiment of the present utility model is carried out specifically referring to the drawings
It is bright.
As shown in figure 1, the burning oxygen pipe igniter 100 involved by embodiment of the present utility model is included burning oxygen pipe 1,
Oxygen supply portion 2, magnetic valve 3, frequency conversion heater 4, temperature sensor 5 and controller (not shown).In addition, to of the present utility model
Burning oxygen pipe igniter 100 involved by embodiment also includes burning oxygen handle 6 and flexible pipe 7.
Burn oxygen pipe 1 to be made up of metal material, constituted such as the alloy by steel.Oxygen supply portion 2 is by hand off valve, decompression
Valve, oxygen pipeline delivery pipe etc. are constituted, for supplying oxygen to burning oxygen pipe 1.Oxygen handle 6 is burnt by being unlikely to deform not transcalent gold
The materials such as category are constituted, and have a pipeline (not shown) for running through two ends inside it.Flexible pipe 7 is by easily deformable rubber etc.
Material is constituted.The one end for burning oxygen pipe 1 is opening, and the other end of burning oxygen pipe 1 is with burning one end (one end of pipeline) of oxygen handle 6 even
Connect.In addition, the other end (other end of pipeline) for burning oxygen handle 6 is connected with one end of flexible pipe 7, the other end of flexible pipe 7 and oxygen supply
Portion 2 is connected.In addition, being provided with magnetic valve 3 on flexible pipe 7.Thus, burn oxygen pipe 1, burn oxygen handle 6 and the composition oxygen supply stream of flexible pipe 7
Road, the oxygen supply runner can be supplied the oxygen in oxygen supply portion 2 to the one end for burning oxygen pipe 1.
Magnetic valve 3 is under valve opening state (open mode), it is allowed to be stored in oxygen in oxygen supply portion 2 to burning the one of oxygen pipe 1
End is supplied；Under closed valve state (closed mode), block runner to forbid supplying oxygen to the one end for burning oxygen pipe 1.
Frequency conversion heater 4 is used to heat the one end for burning oxygen pipe 1.In addition, as shown in Fig. 2 frequency conversion heater 4 has
Heating coil 41 and insulating ceramics portion 42.After heating coil 41 is powered, burning oxygen tube end just can be made to produce eddy-current heating so as to right
Heated the one end for burning oxygen pipe 1.Insulating ceramics portion 42 is arranged on the inner circumferential of heating coil 41, and oxygen pipe 1 is burnt for placing
One end.
Temperature sensor 5 is realized that the temperature for one end to burning oxygen pipe 1 is examined by infrared temperature sensor etc.
Survey.
Controller carries out wire communication or radio communication with temperature sensor 5 and magnetic valve 3 respectively.In addition, control
The temperature of one end of burning oxygen pipe 1 of the device according to detected by temperature sensor 5 and the state to magnetic valve 3 is switched over.That is, control
Device processed is when the temperature that temperature sensor 5 detects the one end for burning oxygen pipe 1 reaches burning-point (for example, 1500 degrees Celsius), by electromagnetism
Valve 3 switches to valve opening state from closed valve state, is then burnt and is lighted a fire in pure oxygen using metal.
In the burning oxygen pipe igniter 100 of present embodiment, though it is not powered on heating or heater wire in heating coil 41
The temperature for enclosing heated one end for burning oxygen pipe 1 detected by 41 electrified regulations but temperature sensor 5 does not reach the situation of burning-point
Under, magnetic valve 3 is in closed valve state all the time, forbids oxygen to be supplied from oxygen supply portion 2 to the one end for burning oxygen pipe 1.
On the other hand, one end of heated burning oxygen pipe 1 is detected in the electrified regulation temperature sensor 5 of heating coil 41
When temperature reaches burning-point, will reach that the corresponding signal of burning-point is transmitted to controller with temperature, controller receive with
Temperature is reached after the corresponding signal of burning-point, and the signal corresponding with switching to valve opening state, magnetic valve are sent to magnetic valve 3
3 after the signal corresponding with switching to valve opening state is received, valve opening state is switched to from closed valve state.Thus, oxygen supply
Oxygen in portion 2 is supplied to one end of heated burning oxygen pipe 1, so that the one end for burning oxygen pipe 1 can realize that rapid light is gone forward side by side
Row burn-through is handled.
In summary, the burning oxygen pipe igniter 100 according to involved by embodiment of the present utility model, can be realized a little
Fire automation and improve igniting reliability.
