Example Embodiment

[0031] Example 1

[0032] The recycled material is mainly Zr-Ti-Ni-Cu quaternary alloy, and the surface of the recycled material is slightly dirty.

[0033] Step 1: Mechanically crush the zirconium-based amorphous alloy recycled material, and control the size within the range of 1-5cm.

[0034] Use a roller crusher to crush the recycled material that needs to be processed. The crushing time is suitable for the maximum size not to exceed 5cm, and the optimal size is controlled within the range of 1-5cm. The crushed recycled material has a suitable size, and can be transported between processes by using a conveyor belt, saving manpower.

[0035] Step 2: Wash the crushed recycled material with oxalic acid solution, and then wash with water until there is no residue on the surface of the recycled material.

[0036] Step 3: ultrasonically clean the pickled recycled material in the cleaning solution, then wash with water until there is no residue on the surface of the recycled mat...

Example Embodiment

[0039] Example 2

[0040] The recycled materials are mainly recycled materials of various zirconium-based amorphous alloys, and the surface of the recycled materials is seriously dirty.

[0041] Step 1 is the same as in Example 1.

[0042] Step 2: Wash the crushed recycled material with phosphoric acid solution, and then wash with water until there is no residue on the surface of the recycled material.

[0043] Step 3: ultrasonically clean the pickled recycled material in the cleaning solution, then wash with water until there is no residue on the surface of the recycled material, and then dry. The formula of the alkaline solution in the cleaning solution is that the addition amount of sodium hydroxide is 12wt%, the addition amount of sodium carbonate is 10wt%, the addition amount of sodium silicate is 3wt%, and the surfactant is sodium butylnaphthalene sulfonate, and the content accounts for the cleaning solution. 10wt%. The ultrasonic cleaning time was 5 min, and the wate...

[0046] Example 3

[0047] The recycled material is mainly a mixture of recycled materials of various zirconium-based amorphous alloys containing aluminum elements, and the surface of the recycled materials is less dirty.

[0048] Step 1 is the same as in Example 1.

[0049] Step 2: Use citric acid solution to wash the crushed recycled material, and then wash with water until there is no residue on the surface of the recycled material.

[0050] Step 3: ultrasonically clean the pickled recycled material in the cleaning solution, then wash with water until there is no residue on the surface of the recycled material, and then dry. The alkaline solution formula in the cleaning solution is that the addition amount of sodium carbonate is 15wt%, the addition amount of sodium pyrophosphate is 8wt%, the addition amount of sodium silicate is 2wt%, and the surfactant is fatty alcohol polyoxyethylene ether sodium sulfate, and the content is Cleaning solution 20wt%. The ultrasonic cleani...

Abstract

The invention discloses a recovery method of zircon-based amorphous alloy. The method comprises the following steps: crushing; pickling; performing alkaline cleaning; adding oxophile elements to smelt; filtering through foamed ceramics. With the adoption of the recovery method, the content of oxygen elements in the recovered zircon-based amorphous alloy can be greatly reduced, and moreover, inclusions in the alloy can be effectively removed, so that the recovered zircon-based amorphous alloy can reach the purity for recycling. Meanwhile, the method is simple, practical, easy to operate, and suitable for popularization and application.

Description

technical field [0001] The invention relates to a recovery method of a zirconium-based amorphous alloy, in particular to a method for removing impurities in the zirconium-based amorphous alloy by cleaning, blowing inert gas and filtering through foam ceramics to achieve the purpose of recovering the alloy. Background technique [0002] Amorphous alloys have attracted great attention because of their special amorphous structure, high hardness, high strength, self-sharpening, high fracture toughness and excellent corrosion resistance. At present, more and more amorphous alloy systems have been developed and applied, such as iron-based amorphous alloys, zirconium-based amorphous alloys, cobalt-based amorphous alloys, aluminum-based amorphous alloys, etc., among which zirconium-based amorphous alloys have high With excellent amorphous forming ability and good casting performance, it has been widely used in consumer electronics, medical equipment, automobile industry, military in...
