The present invention comprises: zirconium sponge is pressed into zirconium electrodes; the present invention is characterized in that prepared niobium bars, which have the length of equal to that of the zirconium electrode, and the zirconium electrodes are welded into zirconium-niobium composite electrode bars; the zirconium niobium composite electrode bars are welded into consumable electrodes, and then the consumable electrodes are smelted. The present invention has simple technical process, the prepared zirconium-niobium alloy has accurate ingredient, and the present invention is an ideal method for preparing a zirconium-niobium alloy.
Description
A kind of preparation method of zirconium-niobium alloy relates to a kind of preparation method who is used for the non-ferrous metal binary alloy of nuclear reactor, particularly adds the method for niobium in the zirconium metal.
At present, in the preparation process of existing zirconium-niobium alloy, the adding of niobium is to add with the form of Zr-Nb master alloy in its alloy.Its concrete grammar is at first selected short grained atomic level zirconium sponge and the pure niobium of scutellate refining, press the proportioning of 60%Nb-40%Zr, in the non-consumable arc furnace or the copper crucible in the weldering case of vacuum argon filling, with electric arc make that it is melt-blended, solidify, melt-blended, resolidification again, repeated multiple times, till be sure oing both mix, be cooled to room temperature.Be machined into chip after the taking-up.When the compacting electrode, be the centre that strip is clipped in zirconium sponge by the amount of calculating with pure zirconium paper tinsel parcel master alloy, be pressed into electrode, be smelted into ingot twice through vacuum consumable electrode arc furnace then.This alloy preparation method at first needs preparation and melting master alloy, and complex process is wanted artificial spreading master alloy during the compacting electrode, and the granulous master alloy drops out easily, influences the accuracy of alloy ingredient.And the master alloy alloy only is present on the medullary ray of electrode, is not easy to stir, and easily causes the segregation of alloy ingredient.
Purpose of the present invention is exactly the complex process that exists among the preparation method who overcomes above-mentioned zirconium-niobium alloy, be difficult to accurately control alloying constituent, cause the shortcoming of composition segregation easily, provide a kind of new method simple, can accurately control alloy ingredient, effectively reduce the preparation method of the existing zirconium-niobium alloy of composition segregation.
The objective of the invention is to be achieved through the following technical solutions.
A kind of preparation method of zirconium-niobium alloy, the weight ratio that this zirconium-niobium alloy contains niobium is 0.35%-2.8%, it is characterized in that preparation process is: a. selects the zirconium sponge of atomic level, through removing impurity, cleaning, vacuum drying, being pressed into zirconium electrode; B. with atomic level niobium bar, purify, become ingot, pass through forging, hot rolling, cold rolling one-tenth niobium plate then through electron beam furnace; C. the niobium plate is cut into the niobium bar identical, the niobium bar tightly is attached on the zirconium electrode with zirconium electrode length, in vacuum argon filling weldering case, that the niobium bar is welded together with zirconium electrode then, make zirconium niobium combined electrode rod; D. the zirconium niobium combined electrode rod that makes is welded into consumable electrode, will makes consumable electrode and in consumable electrode vacuum furnace, carry out melting, obtain zirconium-niobium alloy.
The preparation method of a kind of zirconium-niobium alloy of the present invention, its technological process is simple, saved the process of preparation master alloy in the prior art, adopt alloy preparation method of the present invention, overcome artificial spreading master alloy, the granulous master alloy drops out the shortcoming of the inaccurate and composition segregation of the alloy ingredient that causes, and the zirconium-niobium alloy composition of preparation is accurate, being evenly distributed, is a kind of preparation method of more satisfactory zirconium-niobium alloy.
