Abstract: A method for regenerating different types of copper-containing aluminum alloys using aluminum alloy scrap from aeronautical industry includes detecting a chemical composition of said aluminum alloy scrap and optionally adding a suitable amount of a metal or alloy additive according to a composition requirement of a target aluminum-copper alloy, thereby obtaining a mixture of aluminum alloy scrap and metal or alloy additive; vacuum smelting the mixture of aluminum alloy scrap and metal or alloy additive in a vacuum furnace, wherein impurities are removed and an aluminum alloy solution is formed; filtering the aluminum alloy solution using a filter to obtain a melt comprising a target aluminum alloy composition; and casting the target aluminum alloy composition from said melt.

Abstract: A method for recycling an aluminum alloy scrap includes performing selective oxidation roasting and washing treatment on the aluminum alloy scrap to obtain an uncoated aluminum alloy scrap; melting the uncoated aluminum alloy scrap in a refining furnace to obtain aluminum alloy melt liquid, online-detecting components of the aluminum alloy melt liquid and adding a metallic copper, a copper alloy, a magnesium alloy or a zinc alloy to the aluminum alloy melt liquid according to the requirements of target alloy components, performing pressure-controlled and oxygen-controlled melting through regulating pressure intensity and oxygen partial pressure in the refining furnace and coupling an external-field stirring mode to obtain refining aluminum alloy melt liquid; filtering the refining aluminum alloy melt liquid, to obtain an aluminum alloy melt with the target alloy components; and casting the aluminum alloy melt.

Abstract: The present application relates to an intelligent recommendation method, a terminal, and a server. The method includes: displaying a first modification interface in response to a first operation that is input by a user. The first modification interface displays a plurality of recommendation parameters. The method further comprises sending a first modification request to a first server in response to a second operation that is input by the user. The first modification request requests the server to modify at least one recommendation parameter. The method further comprises sending a recommendation request to the server, receiving a recommended content from the server and displaying the recommended content.
