Description

technical field

[0001] The high aluminum alloy product belongs to the category of master alloy of steel or iron, is a deoxidation product used for deoxidation of molten steel in the steelmaking process and a master alloy mixed with aluminum element in steel, and its preparation method belongs to the technical field of ferroalloy smelting. Background technique

[0002] As we all know, steelmaking is an oxidation-reduction reaction at high temperature. The steel material will be oxidized to different degrees during the melting process, and the oxygen content in the steel will also increase sharply due to the oxidation of the steel material, which will cause a large loss of alloy elements added to the steel during the refining process, which not only enhances the steelmaking process Cost, waste of resources, but also directly affect product quality due to excessive oxygen content in steel. For a long time, in order to reduce the oxygen content in steel, pure aluminum is genera...
