Title:
IRON-ALUMINUM ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/169074
Kind Code:
A1
Abstract:
Disclosed are an iron-aluminum alloy and a preparation method therefor. In the iron-aluminum alloy, iron accounts for 50-80% in percentage by weight, and the balance is aluminum. The method comprises: adding metallic aluminum or molten aluminum into a container, wherein the temperature of the molten aluminum is 700-800°C; adding a metal iron raw material into the molten aluminum, closing a furnace cover, measuring the pressure, and injecting argon so as to cause the interior of a magnetic induction electric furnace to be in a positive pressure state, and performing stirring with a graphite stirring head; powering on the furnace and performing heating to raise the temperature, so that the temperature of the metallic aluminum or molten aluminum is increased to 1000°C or above until same is molten, and maintaining the temperature between 1000°C and 1500°C; and after alloying is completed, performing cooling to approximately 1000°C, opening the furnace cover and taking out the iron-aluminum alloy. Compared with existing products, the iron and aluminum in the iron-aluminum alloy prepared by the present invention are fully alloyed, improving the absorption rate of an iron additive as an alloying element in the molten aluminum during an aluminum processing and smelting process, improving the physical properties of the processed aluminum, and reducing environmental pollution in the production process.
