Embodiment 1

[0022] Example 1: Grinding the electrolytic manganese flakes into powder, the particle size of the manganese powder is below 0.6 mm (30 mesh). Divide the content into MgCl 2 Base fusion 70% (mass percentage) of MgCl 2 Heat and melt with 30% (mass percentage) of KCl, stir evenly, cool and solidify, then crush and grind into powder, the powder particle size is less than 0.6 mm (30 mesh), forming MgCl 2 base fusion powder. Take 700g of manganese powder and 300g of MgCl 2 The base fusion powder was uniformly mixed, and then pressed into blocks of 1000 g each with a press.

Embodiment 2

[0023] Example 2: Grinding the electrolytic manganese flakes into powder, the particle size of the manganese powder is below 0.6 mm (30 mesh). Divide the content into MgCl 2 40% (mass percent) MgCl of base fusion 2 Heating and melting with 60% (mass percentage) of KCl, stirring evenly, cooling and solidifying, then crushing and grinding into powder, the powder particle size is less than 0.6 mm (30 mesh), forming MgCl 2 base fusion powder. Take 700g of manganese powder and 300g of MgCl 2 The base fusion powder was uniformly mixed, and then pressed into blocks of 1000 g each with a press.

Embodiment 3

[0024]Embodiment 3: Grinding the electrolytic manganese flakes into powder, the particle size of the manganese powder is below 0.6 mm (30 mesh). Divide the content into MgCl 2 Base fusion 58% (mass percentage) of MgCl 2 Heating and melting with 42% (mass percentage) of KCl, stirring evenly, cooling and solidifying, then crushing and grinding into powder, the powder particle size is less than 0.6 mm (30 mesh), forming MgCl 2 base fusion powder. Take 900g of manganese powder and 100g of MgCl 2 The base fusion powder was uniformly mixed, and then pressed into blocks of 1000 g each with a press.

Abstract

Disclosed is an alloy element additive used for aluminum alloy production. The alloy element additive is composed of alloy element powder to be added, mgcl2-group fusion powder and an adhesive. The components comprise, by mass, 70%-90% of the alloy element powder, 10%-30% of the mgcl2-group fusion powder and 0-5% of the adhesive. The sum of the mass percents of the three components is 100%. Alloy elements are organically combined with a refining agent, so that the alloy element additive not only has an alloying function, but also has a refining effect. According to the alloy element additive and a preparation method thereof, mgcl2-group fusion serves as a fusing agent, so that not only is the fusing function to the alloy element powder achieved, but also the refining function to aluminum water is achieved, and accordingly the agent is multipurpose indeed. The alloy element additive does not contain toxic substances, thereby being safe and environmentally friendly

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy production, and in particular relates to an alloy element additive for aluminum alloy production. Background technique [0002] In the production process of aluminum alloy, it is often necessary to add various alloying elements such as manganese, iron, silicon, magnesium, and copper. The addition of these alloying elements is mainly carried out through intermediate alloys or alloying element additives. The so-called alloying element additive is a block formed by mixing alloying element powder and other fluxes. [0003] Since the advent of alloying element additives, it has been welcomed by the casting industry. This additive is easy to use and can be easily put into the melting furnace without requiring special equipment. The additive block has a relatively large specific gravity, and it sinks naturally after being put into the metal solution, which prevents the powder from being scatter...
