Embodiment Construction

[0032] Step 1: Select the formula of each element and substance according to the table below, and calculate the weight of each substance required based on the total amount of the prepared alloy of 1000kg.

[0033]

[0034] Step 2: First add aluminum ingots or molten aluminum into the melting furnace, heat it to melt it completely and keep it warm at 700-800°C; the melting process is completed in a closed environment;

[0035] Step 3: Add the alloy elements selected in Step 1 according to the proportion of the formula to completely dissolve and melt them, and stir the mixed melt evenly;

[0036] Step 4: Refining the above alloy melt in a furnace; adding a refining agent to the alloy melt and stirring evenly, and the melt refining is operated in a closed environment;

[0037] Step 5: After refining and removing slag, degas the melt with protective gas argon and 0.5% (volume ratio) chlorine, and simultaneously make the cyano complex modifier Y n [M(CN) m ] (50 mesh) is added...

Abstract

The invention discloses an aluminum alloy material processed by cyano complex and a preparation method of the aluminum alloy material. The aluminum alloy material comprises the alloy ingredients by mass fraction: 1.0-3.0% of Cu, less than or equal to 0.2% of Mn, 1.2-1.8% of Mg, 0.8-1.5% of Ni, less than or equal to 0.3% of Zn, less than or equal to 0.15% or less of Ti, less than or equal to 1.2% of Si, less than or equal to 1.6% of Fe and then balance of Al and inevitable impurities wherein a cyano complex modificator Yn[M(CN)m] is 0.01-2% of total mass of furnace charge. The casting defects of the aluminum alloy material disclosed by the invention are obviously reduced.

Description

technical field [0001] The invention belongs to the field of aluminum alloy materials, and relates to an aluminum alloy material treated with a cyano complex and a preparation method thereof. Background technique [0002] Aluminum alloy is a relatively young metal material, which only began to be used industrially in the early 20th century. During World War II, aluminum was mainly used in the manufacture of military aircraft. After the war, due to the sharp decrease in the demand for aluminum in the military industry, the aluminum industry began to develop civilian aluminum alloys, expanding its application scope from the aviation industry to the construction industry, container packaging industry, transportation industry, electric power and electronics industry, Various sectors of the national economy such as machinery manufacturing and petrochemicals are applied to people's daily lives. At present, aluminum is used in a large amount and in a wide range, second only to st...
