Embodiment 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 materials that need to be processed. The maximum size of the crushing time should not exceed 5cm, and the size control is best within the range of 1-5cm. The size of the crushed recycled materials is appropriate, and the conveyor belt can be used for transportation between processes, saving manpower.

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

[0036] Step 3: Ultrasonic cleaning the reclaimed material after pickling in the cleaning solution, then washing with water until there is no residue on the surface of the reclaimed material, a...

Embodiment 2

[0040] Recycled materials are mainly recycled materials of various zirconium-based amorphous alloys, and the surface of 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 it with water until there is no residue on the surface of the recycled material.

[0043] Step 3: Ultrasonic cleaning the reclaimed material after pickling in the cleaning solution, then washing with water until there is no residue on the surface of the reclaimed material, and drying. The formula of the alkaline solution in the cleaning solution is 12wt% of sodium hydroxide, 10wt% of sodium carbonate, 3wt% of sodium silicate, butylnaphthalene sodium sulfonate as a surfactant, and its content accounts for 1% of the cleaning solution. 10wt%. The ultrasonic cleaning time is 5 min, and the water used in steps 2 and 3 is deionized water. If the dirt cannot be completely removed at on...

Embodiment 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 relatively lightly dirty.

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

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

[0050] Step 3: Ultrasonic cleaning the reclaimed material after pickling in the cleaning solution, then washing with water until there is no residue on the surface of the reclaimed material, and drying. The alkaline solution formula in the cleaning solution is that the addition of sodium carbonate is 15wt%, the addition of sodium pyrophosphate is 8wt%, the addition of sodium silicate is 2wt%, and the surfactant is fatty alcohol polyoxyethylene ether sodium sulfate, the content of which is Cleaning solution 20wt%. The ultrasonic cleaning time is 2min...

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...
