Embodiment Construction

[0032] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate, and these examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0033] like Figure 1-2 As shown, the present invention proposes a kind of smelting method of ZL114A alloy, comprises the steps:

[0034] S1, adding high-purity aluminum ingots to melt;

[0035] S2, adding high-purity Si at 700-800°C;

[0036] S3, master alloy modification and refinement;

[0037] S4. Refining by high-purity argon rotary blowing method;

[0038] S5, pouring after standing still.

[0039] In this example, in S3, the alloys added in modification and refinement include imported AlTiB wire, Al-Sb inter-addition alloy and Al-Te inter-addition alloy.

[0040] In this embodiment, as shown in Figure S4, the rotary injection device used in the rotary injection method includes a furnace body 1 for refi...

Abstract

The invention discloses a smelting method of a ZL114A alloy. The smelting method comprises the following steps of S1, adding a high-purity aluminum ingot for melting; S2, adding high-purity Si at the temperature of 700-800 DEG C; S3, performing intermediate alloy modification and refinement; S4, performing refining by a high-purity argon rotary blowing method; and S5, performing pouring after standing. The method is easy to operate, short in smelting time and high in efficiency, and the alloy is not prone to gas suction; by performing intermediate alloy modification, alloy liquid is pure, and molten aluminum is high in quality; and by performing refining by the high-purity argon rotary blowing method, the effect is good, no toxicity or odor exists, environmental friendliness is achieved, and no pollution is caused.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and in particular relates to a method for smelting a ZL114A alloy. Background technique [0002] The aerospace base is a large thick-walled part (thickness 0.2m, length 10m), which requires alloys with good fluidity and high mechanical properties. At present, ZL114A is mainly used in the aerospace field. Because of its high Si content, the liquid metal has good fluidity and can form large thick castings. Due to the addition of trace Mg elements, it can form Mg 2 Si is precipitated and subjected to aging strengthening treatment, so it has higher strength and better ductility. In order to ensure high mechanical properties of aerospace products, the ZL114A aluminum alloy material used is generally made of refined aluminum (Al≥99.85%) in a vacuum test furnace. However, in the actual production process, the operation is more complicated, the smelting time is long, and the alloy is not easy to...
