Problems solved by technology

However, according to measurements and statistics, when high-magnesium alloys are smelted without using sodium-containing slagging agents, the aluminum content in the aluminum slag is about 50-60%, resulting in the loss of metal resources and unnecessary economic losses for enterprises.

Abstract

The invention discloses an aluminum-magnesium alloy slag removing agent, a method for producing an aluminum-magnesium alloy ingot and the aluminum-magnesium alloy ingot, and belongs to the field of chemistry. The aluminum-magnesium alloy slag removing agent contains the following components: KR1, MgR22 and K3A1R36, wherein R1, R2 and R3 are an element in halogens respectively. The aluminum magnesium alloy slag removing agent claimed by the invention does not contain sodium salt, and can prevent combustion of aluminum slag and increase the slag removing capability of a solvent and the aluminum and slag separation effect.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to the field of producing aluminum-magnesium alloy ingots, in particular to an aluminum-magnesium alloy slag breaking agent. Background technique [0002] At present, aluminum-magnesium alloy ingots with high magnesium content such as 5052 and 5083 are produced. Due to the high sodium content in aluminum water, cracks are very serious during casting and hot rolling, which is the "sodium brittleness" of high-magnesium alloys. Therefore, in order to prevent "sodium brittleness", fluxes containing sodium salts are generally not used in the smelting process of high-magnesium alloys, that is, traditional sodium-containing slag agents are not used. However, according to measurement and statistics, when high-magnesium alloys are smelted without using sodium-containing slagging agents, the aluminum content in the aluminum slag is about 50-60%, resulting in the loss of metal resources and unnecessar...
