Method for adding instant silicon in aluminum alloy smelting process and aluminum alloy smelting

Technical Field

The invention relates to the technical field of metal smelting, in particular to an adding method of instant silicon in an aluminum alloy smelting process and aluminum alloy smelting.

Background

Because the weight of the instant silicon is light, the instant silicon is added in the process of smelting the aluminum alloy and then floats on the surface of the aluminum liquid, the aluminum liquid can not be completely absorbed, when the aluminum alloy with high silicon content is smelted, such as 6 series aluminum alloy, the actual yield of the instant silicon is far from the expectation, the instant silicon alloy is wasted, the production progress is delayed, and the production efficiency is verified to be influenced.

Disclosure of Invention

The invention mainly solves the technical problem that the absorption efficiency of the instant silicon is low in the aluminum alloy smelting process in the prior art.

A method for adding instant silicon in an aluminum alloy smelting process comprises the following steps:

before smelting, the instant silicon is uniformly paved on the bottom of the furnace, and then other smelting raw materials are added for smelting.

An aluminum alloy smelting method comprises the following steps:

before smelting, uniformly spreading instant silicon on the bottom of a furnace;

adding other raw materials required by smelting, and then carrying out a material melting process;

removing floating slag after material melting;

then adding the rest alloy;

and stirring uniformly after the instant silicon is fully absorbed.

According to the method for adding the instant silicon in the aluminum alloy smelting process, before smelting, the instant silicon is uniformly paved on the bottom of the furnace, and then other smelting raw materials are added for smelting. The detection shows that the yield of the instant silicon in the product finally obtained by the instant silicon adding method of the embodiment reaches 98-99%, the production cost is reduced, and the production efficiency is greatly improved.
