specific Embodiment approach 1

[0015] Specific Embodiment 1: In this embodiment, the mass percentage of each element in an aluminum alloy for an erbium-containing tank body is as follows: Mg: 4.0% to 4.9%, Mn: 0.40% to 1.00%, Er: 0.25% to 0.40%, Zr: 0.15%~0.30%, Be: 0.0005%~0.005%, Si﹤0.15%, Fe﹤0.25%, Ti<0.15%, single impurity≤0.05%, total impurity≤0.15%, the balance is Al.

[0016] The impurity elements in this embodiment originate from aluminum ingots; impurities Si﹤0.15%, Fe﹤0.25%, Ti<0.15%, other individual impurities≤0.05%, and the total impurities≤0.15%. performance is not affected.

[0017] Compared with general aluminum-magnesium alloys, the aluminum alloy for erbium-containing tanks in this embodiment can achieve the effects of grain refinement, recrystallization inhibition and solid solution strengthening due to the reasonable addition of Er element, and the addition of Zr element , refine the casting structure, change the crystal shape of the second phase, form a fine dispersed phase, and avoid ...

specific Embodiment approach 2

[0018] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the mass percentages of the elements in the aluminum alloy for erbium-containing tanks are as follows: Mg: 4.6%, Mn: 0.6%, Er: 0.26%, Zr: 0.16% , Be: 0.0025%, Si﹤0.15%, Fe﹤0.25%, Ti<0.15%, single impurity≤0.05%, total impurity≤0.15%, and the balance is Al. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0019] Specific embodiment three: the manufacturing method of a kind of aluminum alloy sheet material for erbium-containing tank body in this embodiment comprises the following steps:

[0020] 1. Ingredients: According to the mass percentage of each element in the aluminum alloy containing erbium tank, Mg: 4.0%-4.9%, Mn: 0.40%-1.00%, Er: 0.25%-0.40%, Zr: 0.15%-0.30%, Be: 0.0005% to 0.005% and the ratio of the balance Al to weigh pure aluminum ingots, pure magnesium ingots, aluminum-manganese master alloys, aluminum-erbium master alloys, aluminum-beryllium master alloys and aluminum-zirconium master alloys;

[0021] 2. Melting: A. Add the pure aluminum ingot, aluminum-manganese master alloy and aluminum-zirconium master alloy weighed in step 1 into the melting furnace. The melting temperature is 750-800°C. When the melt temperature reaches ≥780°C, add aluminum erbium For the master alloy, after adding the aluminum-erbium master alloy, keep warm for 20 minutes and then stir for ...

Abstract

The invention relates to aluminum alloy for an erbium-containing tank and a plate manufacturing method for the aluminum alloy, and aims to improve the welding property and the corrosion resistance ofthe alloy for the erbium-containing tank. The aluminum alloy for the erbium-containing tank comprises the following elements: Mg, Mn, Er, Zr and Be. The method comprises the following steps: (1), blending, (2), smelting, (3), casting, (4) homogenizing annealing, (5) hot rolling, and (6) saw cutting of a finished product to obtain the aluminum alloy for the erbium-containing tank. By a manufacturedalloy plate for the erbium-containing tank, the welding property and the corrosion resistance are improved while various properties of common aluminum magnesium alloy are ensured, and therefore, thealloy can meet requirements of a dangerous chemical supplies tank material. The plate manufacturing method is applied to the field of manufacturing of aluminum alloy.

Description

technical field [0001] The invention relates to an aluminum alloy for an erbium-containing tank body and a manufacturing method thereof. Background technique [0002] At present, the tank trucks used for transporting hazardous chemicals such as asphalt, methanol, and ethylene glycol are made of 6mm steel plates and weigh about 4 tons. Because the country has clear regulations on the total weight of transport vehicles, the loading capacity of steel tank trucks is limited and transportation costs increase. The aluminum alloy material is used to make the tank body, which can reduce the weight by more than 50%. The welding performance and corrosion resistance of the currently used high-magnesium aluminum alloy plates are poor, and the service life of the tank body is short. Contents of the invention [0003] The object of the present invention is to provide a kind of aluminum alloy for erbium-containing tank body and a manufacturing method thereof in order to solve the probl...
