specific Embodiment approach 1

[0007] Specific Embodiment 1: The aluminum alloy spectrum and chemical standard sample of this embodiment is composed of the following components according to the weight percentage ratio: Si: 0.05-1.0%, Fe: 0.1-1.5%, Cu: 0.01-0.5%, Mn : 0.05~1.5%, Mg: 1.0~10.0%, Zn: 0.01~0.5%, Ti: 0.01~0.5%, Cr: 0.01~0.5%, Ni: 0.01~0.3%, Be: 0.0001~0.01%, Al: margin.

specific Embodiment approach 2

[0008] Specific embodiment two: In this embodiment, the aluminum alloy spectrum standard sample is processed according to the following steps: a, smelting: first mix Si, Fe, Cu, Mn, Zn, Ti, Cr, Ni, Be in proportion, raise the temperature to Melt the metal at 700-800°C, then add Mg and Al in proportion and stir evenly, then add refiner and refine under the protection of inert gas. The weight percentage of each chemical composition is: Si: 0.05-1.0%, Fe: 0.1-1.5%, Cu: 0.01-0.5%, Mn: 0.05-1.5%, Mg: 1.0-10.0%, Zn: 0.01-0.5%, Ti: 0.01-0.5%, Cr: 0.01-0.5%, Ni: 0.01 ~0.3%, Be: 0.0001~0.01%, Al: balance; b. Casting: After standing still for 30 minutes, in the crystallizer, the water pressure is 0.075~0.05Mpa and the temperature is 730~750℃. Casting at a speed of 1 / min; c, then heat preservation at a temperature of 460-475°C for 12-16 hours, and perform homogenization heat treatment; d, after soaking, use a lathe to peel the ingot for 8-10mm, and use a boring machine to remove the cent...

specific Embodiment approach 3

[0009] Specific embodiment three: the processing method of aluminum alloy chemical standard sample in the present embodiment is characterized in that it is processed according to the following steps: a, smelting: earlier Si, Fe, Cu, Mn, Zn, Ti, Cr, Ni, Be Mix in proportion, raise the temperature to 700-800°C to melt all the metals, then add Mg and Al in proportion and stir evenly, then add refiner and refine under the protection of inert gas, wherein the weight percentage of each chemical component is: Si : 0.05~1.0%, Fe: 0.1~1.5%, Cu: 0.01~0.5%, Mn: 0.05~1.5%, Mg: 1.0~10.0%, Zn: 0.01~0.5%, Ti: 0.01~0.5%, Cr: 0.01~0.5%, Ni: 0.01~0.3%, Be: 0.0001~0.01%, Al: balance; b. Casting: after standing still for 30 minutes, the internal water pressure in the crystallizer is 0.075~0.05Mpa, and the temperature is 730~750℃ Cast at a speed of 170-190mm / min at a temperature of 170-190mm / min; c. Then keep warm for 12-16 hours at a temperature of 460-475°C for homogenization heat treatment; d. ...

Abstract

A method for preparing standard sample includes forming standard sample composition by wt % of 0.05 -1.0% Si, 0.1 -1.5 % Fe, 0.01 -0.5 % Cu, 0.05 -1.5 % Mn, 1.0 -10.0 %Mg, 0.01 -0.5 % Zn, 0.01 -0.5 Ti, 0.01 -0.5 % Cr, 0.01 -0.3 % Ni, 0.0001 -0.01 % Be and Al as allowance ; mixing and melting above material except Mg and Al ; adding mg and Al in and agitating the material for refining ; casting the material in crystallizer after 30 min resting ; carry out homogenizing treatment ; using lathe to move off 8 - 10 mm skin of cast ingot and using the boring mill to cut off phi 22 - 25 mm centre to obtain cylinder spectrum standard sample of aluminium alloy.

Description

Technical field: [0001] The invention relates to a spectroscopic and chemical standard sample of antirust aluminum series aluminum alloy and a production process thereof. Background technique: [0002] With the continuous development of analytical technology and the modernization of analytical testing methods, more users will have more and more demand for standard samples for spectroscopic and chemical analysis. Generally, standard samples of deformed aluminum alloys are subjected to smelting, casting, preliminary inspection of uniformity, homogenization heat treatment, extrusion, and processing before data processing, so that their technological structure state is inconsistent with that of samples used for production analysis, so it cannot be Guarantee the control of product quality. Invention content: [0003] In order to better control the analytical quality of the standard sample for spectral and chemical analysis during use, the present invention provides an aluminum...
