Problems solved by technology

[0003] As the core component inside the generator, the existing wire tubes are made of solid type or with a rectangular inner hole in the processing process, which makes the coil consumables large and also causes the unit to be bulky; single water and hydrogen cooling or hydrogen cooling are used in the processing process The hydrogen cooling method makes the cooling effect of the coil poor; the coreless stretching is used in the stretching process, which leads to low dimensional accuracy and rough inner surface of the stretched finished product, which eventually shortens the service life of the unit

Embodiment Construction

[0036] A specific embodiment of the present invention, the specific embodiment of stretching the tube blank comprises the following steps:

[0037] Step 1, select the tube blank; when selecting the tube blank, first determine the wall thickness dimension of the wire conduit tube blank according to the maximum wall thickness value on the cross-sectional diagonal of the selected tube blank, and the wall thickness dimension of the wire conduit tube blank is 1.05-1.25 times the wall thickness of the corner line; secondly, determine the size parameters of the movable inner mold according to the stretching conditions of the movable mold; thirdly, calculate the round hole size of the intermediate transition product according to the inner hole size of the product; thirdly, according to the determined circle The hole size and the wall thickness on both sides of the length and width of the product are combined with the processing deformation rate to determine the wall thickness of the in...

Abstract

The invention discloses a method for processing the rectangular round hole conductor copper pipe of a double-water internal cooling generator, comprising the following steps: selecting a pipe blank; casting, extruding and stretching the selected pipe blank to form a round pipe blank; rolling the shaped pipe blank; annealing the rolled pipe blank; transiting and stretching the annealed pipe blank; and stretching the transited and stretched pipe blank to form a finished product. With the method, the technical problems of large coil consumable amount, large unit volume, poor coil cooling effect and short service life of the unit because the coil material adopted in the prior art is solid or has a rectangular bore can be solved, and the method has the advantages of material conservation, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of copper material processing, in particular to a processing method for a rectangular round-hole wire copper pipe of a double-water internal cooling generator. Background technique [0002] At present, the 600MW double water internal cooling generator has the dual concept of high power and double water internal cooling, so it will become the development direction of the generator in the future. [0003] As the core component inside the generator, the existing wire tubes are made of solid type or with a rectangular inner hole in the processing process, which makes the coil consumables large and also causes the unit to be bulky; single water and hydrogen cooling or hydrogen cooling are used in the processing process The hydrogen cooling method makes the cooling effect of the coil poor; the coreless stretching is used in the stretching process, which leads to low dimensional accuracy and rough inner surface of ...
