METHOD OF PRODUCING ALUMINIUM ALLOYS CONTAINING LITHIUM |
| 摘要 |
A method of producing molten aluminium-lithium alloys for casting a feedstock in the form of an ingot, the method including the steps of: preparing a molten first aluminium alloy with a composition A which is free from lithium as purposive alloying element, transferring the first aluminium alloy to an induction melting furnace, adding lithium to the first aluminium alloy in the induction melting furnace to obtain a molten second aluminium alloy with a composition B having lithium as purposive alloying element, optionally adding further alloying elements to the second aluminium alloy, transferring the second alloy via a metal conveying trough from the induction melting furnace to a casting station. |

1. A method of producing molten aluminium-lithium alloys for casting a feedstock in the form of an ingot, the method comprising the steps of:
(a) preparing a molten first aluminium alloy with a composition A which is free from lithium as purposive alloying element, (b) transferring the first aluminium alloy to an induction melting furnace, (c) adding lithium to the first aluminium alloy in the induction melting furnace to obtain a molten second aluminium alloy with a composition B having lithium as purposive alloying element, (d) optionally adding further alloying elements to the second aluminium alloy, (e) transferring the second alloy with optional further alloying elements, if any, via a metal conveying trough from the induction melting furnace to a casting station. |
