Description
Technical field
The invention belongs to boiler technology field, and being related to fin panel casing tube sheet plasma surfacing prevents deformation device.
Background technology
In boiler running process, sulphur and other harmful substances can corrode boiler water wall tube sheet during due to coal combustion, therefore,
Boiler water wall tube sheet needs regularly to repair and change, and has upset the normal production order, has added production cost and maintenance
Expense, directly affect the benefit of enterprise.One layer of resistant material of built-up welding will greatly improve water screen tube on water-cooling wall tube sheet
The corrosion resistance of plate, extend its service life, still, in one side weld deposit process, led because water screen tube uneven heating is even
The temperature difference of cause will bring it about deformation.Although at present using water seaoning or the methods of by the use of red copper as cooling pad
Deformation in reduction weld deposit process, but these methods often complex operation, and some methods have the defects of certain.
The content of the invention
It is an object of the invention to provide fin panel casing tube sheet plasma surfacing to prevent deformation device, solves water-cooling wall
The problem of thermal deformation being produced in tube sheet one side bead-welding technology because uneven heating is even.
The technical solution adopted in the present invention is to include water tower, flexible pipe one end connection water tower, other end connection water screen tube
Plate.
Further, water-cooling wall tube sheet slant setting, there is certain angle with horizontal plane.
Further, each water screen tube of water-cooling wall tube sheet water flowing simultaneously, and water-carrying capacity is identical.
Further, tube-shape is variable.
Further, port is completely filled with from the water of water-cooling wall tube sheet other end outflow before welding.
The beneficial effects of the invention are as follows can be according to built-up welding speed and the flow velocity of built-up welding temperature adjustment cooling water, so as to maximum
The elimination weldment deformation of limit.
Brief description of the drawings
Apparatus of the present invention side view of accompanying drawing 1；
Apparatus of the present invention top view of accompanying drawing 2.
In figure, 1. water towers, 2. flexible pipes, 3. water-cooling wall tube sheets.
Embodiment
With reference to embodiment, the present invention is described in detail.
The present invention is the device for preventing weldment from deforming in a kind of weld deposit process.As depicted in figs. 1 and 2, including water tower 1, it is soft
The one end of pipe 2 connection water tower 1, other end connection water-cooling wall tube sheet 3.
The course of work of apparatus of the present invention is as follows：Before built-up welding, according to the stream of built-up welding temperature and the reclaimed water of rate adaptation water tower 1
Amount, cooling water flow into from one end of water screen tube tube sheet 3 through flexible pipe 2, are flowed out from the other end, start to weld.In weld deposit process, lead to
The constant flow of supercooled water reduces welding position and the temperature difference around it, so as to Reducing distortion.From water screen tube tube sheet 3
The water of other end outflow is flowed into cistern, temporarily storage, and after treatment, is pumped into water tower and recycled by water pump.
In apparatus of the present invention, water-cooling wall tube sheet 3 needs slant setting, has certain angle, θ with horizontal plane.In use, water
The water flowing simultaneously of each water screen tube of cold wall tube sheet 3, and water-carrying capacity is identical.The shape of flexible pipe 2 in the present invention is variable.Welding
When, it is necessary to ensure from the water flowed out since the other end of water-cooling wall tube sheet 3 be completely filled with port when could weld.
It is also an advantage of the present invention that：The device can reduce the temperature at built-up welding, whole weldment temperature is tended to be uniform
Change, be finally reached the target for reducing the deflection of weldment.In the device, the flow velocity of water screen tube reclaimed water is controllable, thus can root
According to built-up welding speed and the flow velocity of built-up welding temperature adjustment cooling water, so as to eliminate weldment deformation to greatest extent.The present invention is in water
There is unique advantage in the application of cold wall pipe sheetpile weldering, can be by being passed through cooling water in water screen tube, so as to reach radiating
Purpose, it is simple to operate, it is easy to accomplish, and can effectively solve problem on deformation.
Described above is only the better embodiment to the present invention, not makees any formal limit to the present invention
System, any simple modification that every technical spirit according to the present invention is made to embodiment of above, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
