Abstract
The invention discloses a preparation method for a dry method revolving furnace pipe in nuclear energy industry. The furnace pipe is formed through adopting the integral cold drawing manner; the formed furnace pipe barrel body is processed by an aligning machine; flange blanks are welded with the barrel body in a pairing manner; shoveling plates and rib plates at the two ends are subjected to group-welding; the excircles and the sealing surfaces of the flanges are processed for forming; the bolt holes of the flanges are processed, and the shoveling plates are connected through rivets. The furnace pipe comprises a barrel body, flanges at the two ends of the barrel body, and the shoveling plates uniformly distributed on the inner wall of the barrel body, wherein the barrel body is formed through integral cold drawing; the rib plates in the barrel body are welded onto the inner walls of the two end openings of the barrel body; annular plates are welded with the shoveling plates in a pairing manner and are uniformly distributed in the longitudinal direction of the shoveling plates; the shoveling plates and the rib plates are connected through rivets. According to the preparation method, the integral cast expensive in cost and the sheet metal technology easy to cause corrosion are abandoned, and through adopting the furnace pipe integral cold drawing, the straightness and the roundness of a prepared furnace pipe barrel body can completely meet the quality requirements for the dry method revolving furnace pipes in nuclear energy industry; moreover, as the shoveling plates adopt a detachable rivet connection structure, the problems such as the shoveling plates are difficult to weld and easy to corrode are solved, and the shovelling plates are convenient to replace.
Description
Technical field
The invention belongs to equipment processing technique field, be specifically related to a kind of preparation method for nuclear energy industry dry method converter boiler tube.
Background technology
At present, in nuclear energy industry field, need to use a kind of dry method converter, its converter boiler tube is all generally from French import, by whole cast, expensive.And the current casting technique of China can not reach this requirement, therefore cannot process preparation dry method converter boiler tube.
The current domestic converter boiler tube of making generally adopts sheet metal process segmentation to roll and is welded, flight segmentation welding.Because welding stress is large, welding region easily corrodes, and boiler tube service life that the method is made is short and be difficult to maintenance, once this converter that is damaged only has to stop production, changes boiler tube, and the economic loss causing is larger.
Summary of the invention
The object of the invention is to propose a kind of monoblock cast and sheet metal process of not adopting, and adopt the boiler tube preparation method of global formation.
Main technical schemes of the present invention: for the preparation method of nuclear energy industry dry method converter boiler tube, it is characterized in that described boiler tube comprises flange and the uniform flight of cylinder inboard wall at cylindrical shell, cylindrical shell two ends, cylindrical shell is that whole cold-drawn forms, in cylindrical shell, gusset is welded on cylindrical shell two-port inwall, ring flat-plate and flight assembly welding, uniform along flight length direction, flight adopts rivet to be connected with gusset; Described boiler tube adopts following preparation method: (1) boiler tube adopts whole group's body cold-drawn to form; 2) the boiler tube cylindrical shell centering machined after moulding; 3) by the welding of flange blank and Cylinder assembly, the flight gusset plate at assembly welding two ends, detect qualified after, body vibration stress-removal is processed; 4) Vehicle Processing flange excircle, sealing surface moulding, the bolt hole of boring processing flange, rivet connects flight.
Dry method Converter tubular construction of the present invention, modal boiler tube main body is cylindrical shell, the uniform 6 groups of flights of cylinder inboard wall, have stricter requirement to the linearity of cylindrical shell and circularity.The little cylindrical shell length of this diameter of work is long, and flight assembly welding is the making difficult point of workpiece, and will note flight welding impact on linearity on the impact of circularity and girth welding.
Dry method Converter tube preparation method of the present invention, abandon expensive integral casting method and easily caused the sheet metal process of corrosion, adopt the whole cold-drawn preparation technology of boiler tube, the boiler tube cylindrical shell linearity of preparation and circularity meet the quality requirement of dry method converter boiler tube in nuclear energy industry completely.The difficult problems such as flight employing rivet connection dismountable structure has solved flight welding difficulty, perishable, and be convenient to change, significant to the technology upgrading of breakthrough China nuclear industry development bottleneck, promotion nuclear energy industry.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention dry method converter boiler tube; Fig. 2 is flight and gusset rivet junction structural representation in embodiment.
In figure, 1-flight; 2-gusset; 3-rivet; 4-ring flat-plate.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail.
Embodiment: for the preparation method of nuclear energy industry dry method converter boiler tube, shown in described boiler tube figure accompanying drawing 1, the flange and the uniform flight of cylinder inboard wall that comprise cylindrical shell, cylindrical shell two ends, cylindrical shell is that whole cold-drawn forms, referring to accompanying drawing 2, in cylindrical shell, gusset 2 is welded on cylindrical shell two-port inwall, ring flat-plate 4 and flight 1 assembly welding, uniform along flight 1 length direction, flight 1 adopts rivet 2 to be connected with gusset 2.
Embodiment boiler tube adopts following preparation method: (1) boiler tube adopts whole group's body cold-drawn to form; 2) the boiler tube cylindrical shell centering machined after moulding; 3) by the welding of flange blank and Cylinder assembly, the flight gusset plate at assembly welding two ends, detect qualified after, body vibration stress-removal is processed; 4) Vehicle Processing flange excircle, sealing surface moulding, the bolt hole of boring processing flange, rivet connects flight.
The difficult problems such as embodiment method is easy to make, and flight adopts rivet to connect dismountable structure, has solved flight welding difficulty, perishable, and be convenient to change.Boiler tube cylindrical shell, flight are all without welding, simple for production, have reduced work difficulty, have extended service life of equipment, have increased substantially economic benefit.
