Abstract
The utility model discloses fin panel casing tube sheet plasma surfacings to prevent deformation device, including water tower, and hose one end connects water tower, the other end connects water-cooling wall tube sheet.Water-cooling wall tube sheet slant setting has certain angle, tube-shape variable with horizontal plane.The utility model has the beneficial effects that the flow velocity of cooling water can be adjusted according to built-up welding speed and built-up welding temperature, so as to eliminate weldment deformation to greatest extent.
Description
Technical field
The utility model 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 when due to coal combustion,
Boiler water wall tube sheet needs regularly to repair and replace, and has upset the normal production order, has increased production cost and repair
Expense directly affects 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 extends its service life, still, in single side weld deposit process, is led since water screen tube uneven heating is even
The temperature difference of cause will bring it about deformation.Although existing at present use water seaoning or use red copper as the methods of cooling pad
Reduce the deformation in weld deposit process, but these methods are often complicated for operation, and there are certain defects for some methods.
Utility model content
The purpose of this utility model is to provide fin panel casing tube sheet plasma surfacings to prevent deformation device, solves water
In cold wall tube sheet single side bead-welding technology thermal deformation is led to the problem of since uneven heating is even.
Technical solution used by the utility model be include water tower, hose one end connects water tower, the other end connects water cooling
Wall tube sheet.
Further, water-cooling wall tube sheet slant setting has certain angle with horizontal plane.
Further, tube-shape is variable.
The utility model has the beneficial effects that the flow velocity of cooling water can be adjusted according to built-up welding speed and built-up welding temperature, so as to
Weldment deformation is eliminated to greatest extent.
Description of the drawings
1 utility model device side view of attached drawing；
2 utility model device vertical view of attached drawing.
In figure, 1. water towers, 2. hoses, 3. water-cooling wall tube sheets.
Specific implementation mode
The utility model is described in detail With reference to embodiment.
The utility model 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
1,2 one end of hose connects water tower 1, other end connection water-cooling wall tube sheet 3.
The course of work of utility model device is as follows：Before built-up welding, according to water in built-up welding temperature and rate adaptation water tower 1
Flow, cooling water through hose 2 from one end of water screen tube tube sheet 3 flow into, from the other end flow out, start to weld.Weld deposit process
In, welding position and surrounding temperature difference are reduced by the constant flow of cooling water, to Reducing distortion.From water screen tube
The water of 3 other end of tube sheet outflow flows into cistern, temporarily stores, and after treatment, is pumped into water tower and is recycled by water pump
It utilizes.
In utility model device, water-cooling wall tube sheet 3 needs slant setting, has certain angle, θ with horizontal plane.It uses
When, each water screen tube water flowing simultaneously of water-cooling wall tube sheet 3, and water flow is identical.2 shape of hose in the utility model can
Become.When welding, it is necessary to guarantee when being completely filled with port from the water flowed out since 3 other end of water-cooling wall tube sheet could weld.
The advantages of the utility model, also resides in：The device can reduce the temperature at built-up welding, and entire weldment temperature is made to tend to
Homogenization, is finally reached the target for making the deflection of weldment reduce.In the device, the flow velocity of water is controllable in water screen tube, thus
The flow velocity that cooling water can be adjusted according to built-up welding speed and built-up welding temperature, so as to eliminate weldment deformation to greatest extent.This practicality
It is novel water screen tube sheetpile weldering application in have unique advantage, can by being passed through cooling water in water screen tube, to
Achieve the purpose that heat dissipation, it is easy to operate, it is easy to accomplish, and can effectively solve problem on deformation.
The above is only the better embodiment to the utility model, not makees any form to the utility model
On limitation, every any simple modification made to embodiment of above according to the technical essence of the utility model is equivalent to become
Change and modify, is all within the scope of the technical scheme of the utility model.
