Abstract
The invention discloses a fabrication method of a zirconium alloy pipe. A pipe blank with a through hole is mechanically machined, is preheated and subjected to heat preservation in an electric resistance furnace, is heated in the electric resistance furnace after being coated with a glass antioxidant, then is lubricated with glass powder and is broached by a broaching machine; the blank is air-cooled to room temperature and mechanically machined, then is clad with red copper skin, is then placed in the electric resistance furnace to be heated to 600-800 DEG C, and is extruded in an extruder; and finally, the copper skin coating the inner and outer surfaces of the blank is removed after air cooling is finished, therefore, the zirconium alloy pipe is obtained. The fabricated zirconium alloy pipe has high quality, cannot be oxidized easily, is unlikely absorb hydrogen, is corrosion-resistant, and has long life, high yield and stable performance.
Description
Technical field
The present invention relates to technical field of alloy, specifically the preparation method of a kind of zirconium alloy pipe.
Background technology
Zirconium is a kind of rare metal, has the characteristics such as surprising corrosion resistance, high fusing point, the hardness of superelevation and intensity, is widely used in Aero-Space, military project, nuclear reaction, atomic energy field.Zirconium and zircaloy plasticity are good, can be made into tubing, sheet material, bar and silk material, and wherein tubing is major product.The processing technique of zirconium and zircaloy depends on fundamental property and the nuclear reactor particular/special requirement to zirconium component of zirconium.The fundamental property of zirconium is: is easily polluted by oxygen, nitrogen, hydrogen etc., easy sticking mould, has allomorphism to change.The requirement of zirconium component is that dimensional accuracy is high by nuclear reactor, and microstructural requirements is strict, stable performance.Therefore on prepared by this compo pipe, there is the problems such as suction hydrogen oxidizable, easy, and traditional preparation methods lumber recovery is relatively low, waste metal.
Summary of the invention
The preparation method that it is an object of the invention to provide a kind of zirconium alloy pipe, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of preparation method of zirconium alloy pipe, concrete preparation process is as follows:
(1) Slug preparing, prepares the pipe with through hole by machining, and this pipe one end is with horn mouth, reduce and bore macropore metal loss, and horn mouth is for counter-bore head location and glass dust lubrication；
(2) preheating 100～200 DEG C in resistance furnace, be incubated 1～2h, at pipe sprayed glass antioxidant, it is to avoid during high temperature, hydrogen problem is inhaled in the oxygen uptake of zircaloy；
(3) pipe puts into resistance furnace heating to 700～900 DEG C, is carrying out glass dust lubrication after carrying out glass dust lubrication or sensed stove temperature raising；After glass dust lubrication, enter staving press and carry out reaming, improve the lumber recovery of zircaloy；
(4) after reaming, blank air cooling, to room temperature, carries out machining or Watch glass powder is removed in reconditioning, remove the glass hardening impurity on surface, it is to avoid bring surface defect in follow-up extrusion process；
(5) it is coated with sheet copper, after cladding is good, puts into resistance furnace and heat to 600～800 DEG C, after reaching temperature, enter extruder extruding, remove the copper sheet of surfaces externally and internally cladding after air cooling, obtain zirconium alloy pipe.
As the further scheme of the present invention: in described step (1), the through-hole diameter of pipe is 40～80mm.
As the present invention further scheme: in described step (2), counter bore diameter is big 8～10mm than squeezing needle diameter.
Compared with prior art, the invention has the beneficial effects as follows: the zirconium alloy pipe quality that the present invention prepares is good, not easily oxidized, not easily inhaling hydrogen, corrosion-resistant, the life-span is long, and lumber recovery is high, stable performance.
