Aluminum-magnesium alloy composite casting device

Abstract

The invention relates to an aluminum-magnesium alloy composite casting device, which comprises a composite crystallizer consisting of an inner crystallizer and an outer crystallizer arranged outside the inner crystallizer, and an integrated ingot leading device which has an integrated structure consisting of a base, a core layer ingot leader and a cover layer ingot leader, wherein the core layer ingot leader is aligned to enter the inner crystallizer to form a core layer molten bath before casting; meanwhile, the cover layer ingot leader enters a space between the inner crystallizer and the outer crystallizer, and a cover layer molten bath is formed between the wall of the outer crystallizer, the cover layer ingot leader and the side face of the core layer ingot leader. By introducing a composite crystallizer technology and an integrated ingot leading device technology, the core layer metal and the cover layer metal are synchronously subjected to composite casting, a composite ingot casting process is simplified, and the yield of products is improved. The aluminum-magnesium alloy composite casting device is suitable for composite casting of two or three layers of metal between aluminum, aluminum base alloy, magnesium and magnesium base alloy, and can implement vertical shaft semi-continuous casting and horizontal continuous casting.

Description

technical field [0001] The invention belongs to the technical field of processing and forming of non-ferrous metal metallurgical materials, in particular to a compound casting device for two or three different materials of aluminum, aluminum-based alloy, magnesium and magnesium-based alloy. Background technique [0002] Metal composite board refers to a board covered with another metal on one layer of metal to achieve the effect of saving resources and reducing costs without reducing the use effect (corrosion resistance, mechanical strength, etc.). The traditional metal clad plate adopts rolling clad technology, that is, two or more alloys are melted, homogenized, and hot-rolled into a plate, and the surface is treated, and at high temperature, more new surfaces are created through a large reduction rate to complete the cladding. . This process has defects such as long production cycle, numerous procedures, and high labor intensity, and the composite interface is easily oxi...

Problems solved by technology

[0006] Synchronous casting of core layer and cladding layer dummy ingots mentioned in the patent "Multilayer Dissimilar Aluminum Alloy Simultaneous Composite Casting Method" (Application No.: 200810244176.6) and "Multilayer Dissimilar Aluminum Alloy Synchronous Composite Casting Device" (Application No.: 20081024475.1) , but the dummy part is solidified first by using the core metal (casting first), and then the cladding layer (pouring after) is attached to the core metal to solidify and composite. Separate control can be achieved, otherwise there will be a greater potential safety hazard on site

and limited to shaft type semi-continuous casting
