Description
Technical field
The application belongs to welding aid technical field, and in particular to the preheating and insulation of a kind of welding or postwelding heat
The heater of processing, it can also be used to heating when steel construction is orthopedic.
Background technology
In GB150《Pressure vessel》It is more than 30mm's for the high strength steels such as chrome-molybdenum steel or thickness etc. in standard regulation
When steel manufacture pressure vessel, weld seam must be preheated before equipment welding, welding process must also be incubated, and postwelding is often needed
Eliminate the heat treatment of stress, so preheating and insulation, and the heat treatment of postwelding is a very important link.
The preheating and insulation combustion gas that the country is generally used at present have device in Gas, natural gas, acetylene gas etc..Due to device in Gas and
Gas Prices are higher, therefore, and chrome-molybdenum steel welding preheating and insulation combustion gas generally use acetylene gas.Acetylene gas can occur when lighting a fire
Detonation, combustion process over-emitting black exhaust produces clogged with soot heater nozzles, and the toxic gases such as hydrogen sulfide, hydrogen phosphide are discharged after burning,
And easily there is tempering phenomenon, easily operating personnel are caused with larger harm, but also pollute environment and equipment.
In the prior art, the heater of weld preheating is carried out using acetylene gas, for example, Authorization Notice No. is
CN202162515U Chinese utility model patent discloses " a kind of heater for weld preheating ", as shown in figure 1, its skill
" including mixed combustion gas piping (30), the mixed combustion gas piping (30) includes point of two parallel arrangements to art scheme
It is provided with uniform flame passage (31) towards commissure to be preheated on bye-pass, the length direction of the branch line.Institute
State the entrance point of mixed combustion gas piping 30 to connect with oxygen pipeline 10 and acetylene gas pipeline 20 respectively, other end closing；
Valve 11,21 is designed with the oxygen pipeline 10 and acetylene gas pipeline 20.The mixed combustion gas piping 30 is in arc
Shape structure, flame passage 31 is located at the medial surface of arc mixed combustion gas piping 30.The outside of flame passage 31
Provided with gas skirt 33, the gas skirt 33 is supported on flame passage 31 by gas skirt supporting leg 32." heater two
The flame that flame passage 31 on the parallel branch line of bar is produced can carry out simultaneously whole to the weld seam of two docking parts to be welded
Body is preheated, and the moisture in weld seam its mother metal after such the pre-heat treatment is completely removed, and prevents stomata, the production of crackle in welding
It is raw, while also reducing weld seam due to the stress produced by preheating temperature inequality, it is ensured that welding quality.
The heater of above-mentioned weld preheating is the application for acetylene gas, however, defect of the acetylene gas due to above-mentioned record
And the application combustion gas of non-optimal, also, there is also following some problems in itself for the heater assembly of above-mentioned weld preheating：
（1）The two ends of the branch line of two parallel arrangements in above-mentioned technical proposal constitute frame by pipeline communication respectively
Shape structure.Because there are four right-angled corners in frame-shaped construction so that mixed gas swerves when by right-angled corner, unfavorable
Flowed in the stability of mixed gas, further influence the burning stationarity and uniformity jetted out flames, and the structure causes

Buffering and transition of the gaseous mixture after right-angled corner, are not only wasted, and reduce efficiency of combustion, furthermore gaseous mixture in structure
Flow distance increase cause burning have hysteresis quality, not in time, open spend at top speed it is slow.
（2）The mixed combustion gas piping entrance point respectively with oxygen pipeline and acetylene gas pipeline connection.Oxygen with
Acetylene gas is to be transported to mixed combustion gas piping by respective transfer pipeline respectively to be mixed, in mixed combustion gas
Only have a bit of pipeline in pipeline to be connected with frame-shaped construction pipeline so that oxygen does not have sufficiently to mix with acetylene gas to be begun to
Into the stage to be combusted.
（3）The curved structure of mixed combustion gas piping, and the arcuate structure is the arc along gaseous mixture airintake direction
The center line of shape, i.e. arcuate structure along its length is parallel with gaseous mixture airintake direction or overlaps, and gaseous mixture is entered by pipeline
By once shunting when entering the mixed combustion gas piping of arcuate structure, then arcuately the width of structure is conveyed, by turning
Just enter the position burning for being provided with flame mouth after the second diffluence of Angle Position, burning not in time, is opened and spent slowly at top speed, it is impossible to meet
The quick demand for opening fire；And the device of the structure less stable of itself, the requirement to support will be higher, nose heave pin
Gently, it is careless slightly during operation, it will greatly to influence the quality of Product jointing.
To sum up, a kind of weld heating device of research and development is needed badly.
