Problems solved by technology

[0003] The traditional way of obtaining such clad plates is to hot-roll join slabs of different alloys, thus joining them, for example by welding, and to subsequently roll them into the final product, which has the disadvantage that the interface between the slabs Often metallurgically unclean and layer to layer interbonding can be problematic

Embodiment Construction

[0014] The method according to the invention comprises the following steps:

[0015] (a) providing an elongated solid substrate comprised of a first alloy and a melt of a second alloy;

[0016] (b) providing a casting mold, the base material and the casting mold being movable relative to each other, wherein the casting mold includes a melt supply end for supplying the casting mold with a molten second alloy and a second alloy with a molten second alloy; two alloys downcast onto the output end of the at least one outlet on the substrate;

[0017] (c) while the casting mold and the substrate are continuously moved relative to each other, the molten second alloy is cast down onto the upper surface of the substrate through the at least one outlet of the casting mold at a temperature at which, by weight, Starting from the reference point of the melting zone, the base material is locally at least partially remelted and at least partially mixed with the molten second alloy to form a...

Abstract

The invention relates to a method and equipment for casting a composite metal ingot. The composite metal ingot comprises at least two layers formed by one or more alloys respectively; the method comprises the following steps: providing a long-strip-shaped solid base material composed of a first alloy and a melt of a second alloy; providing a casting crystallization device, wherein the base material and the casting crystallization device can move relatively and the casting crystallization device comprises a melt supplying end for supplying the melted second alloy to the casting crystallization device and an output end for downward casting the melted second alloy to at least one outlet of the base material; downward casting the melted second alloy to the upper surface of the base material at a temperature through the at least one outlet of the casting crystallization device when the casting crystallization device and the base material continuously move relatively; locally re-melting at least part of the base material from a standard point of a re-melting region at the temperature, and mixing at least one part of the base material with the melted second alloy to form an alloy liquid tank; after re-melting, continuously cooling the melted alloy liquid tank, condensing at a position far away from the standard point and connecting the base material, so as to form the composite ingot before the casting crystallization device leaves.

Description

technical field [0001] The present invention relates to a method and an apparatus for casting a composite metal ingot comprising at least two layers each formed from one or more alloys. Background technique [0002] Metal ingots, especially aluminum ingots, have been manufactured for many years using a semi-continuous casting process known as direct chill casting or electromagnetic casting. In this process, molten metal is injected into the top of a bottomless mold and a cooling medium is applied directly to the solidifying surface of the metal as it is withdrawn. Such systems are often used to manufacture square ingots for the manufacture of rolled products such as aluminum alloy sheet. There is a large market for composite ingots consisting of at least two layers of different alloys. Such ingots are used for rolling to make clad plate for various applications such as brazing plate, aircraft plate, automotive clad plate and other uses where surface properties different fr...
