Aluminum alloy material production technology

Abstract

The invention provides an aluminum alloy material production technology. The aluminum alloy material production technology comprises the following steps of S1, smelting in a smelting furnace; S2, primary refining in the smelting furnace; S3, replenishing of intermediate alloy according to a component pre-analysis result, and stirring to make the mixture uniform; S4, secondary refining in the smelting furnace; S5, heat preservation in a standing furnace; S6, after-purification in a tilting furnace; and S7, casting of the purified aluminum alloy melt by using a casting machine to obtain aluminumalloy ingots. An aluminum alloy material is directly produced by using electrolytic aluminum liquid, remelting of the aluminum material is avoided, the technical process is shortened, the loss is reduced, and the performance of the aluminum alloy material is ensured.

Problems solved by technology

[0003] However, in the actual production and manufacturing process, there will always be various metallurgical defects, such as air bubbles and solid inclusions in the product, which ultimately make the product unable to meet the needs of use. Generally speaking, the main reasons for the above defects are The following:

[0004] 1. The smelting process uses block cold aluminum material to remelt the aluminum material to generate an electrolytic aluminum solution. During this remelting process, the metallographic structure of the aluminum alloy is easily changed and the performance of the aluminum alloy material is affected;

[0005] 2. Using traditional refining agents, it is easy to introduce other new impurity elements during the refining process, which will affect the performance of aluminum alloy materials;

[0006] 3. The purification effect is not complete, so that the gas in the aluminum alloy solution is not easy to discharge, which affects the performance of the aluminum alloy material;

[0007] 4. Traditional refining gases are prone to produce new high-temperature refractory substances, which affect the performance of aluminum alloy materials
