Multilayer heterogeneity aluminum alloy synchronous compound casting device

Abstract

The invention provides a multilayer heterogeneity aluminum alloy synchronous compound casting device. A cooling separating board is arranged inside a crystallizer so as to divide the crystallizer into a core solidification area and a coating solidification area; the cooling separating board is a hollow structure with a water inlet and a water outlet provided on the upper part thereof; the lower part thereof is of a double conical shape; a dummy ingot base is designed with unequal height and comprises the core solidification area and the coating solidification area, wherein the coating solidification area is higher than the core solidification area; part of the core solidification area is an indent curve; an oil injection hole and an oil cavity are arranged on upper side of the crystallizer; and the lubricating oil is continuously fed to the compound dummy ingot by the oil cavity during the casting process. When the device is used to perform compound casting, the alloy having higher melting point is firstly casted, the alloy having lower melting point is secondarily casted and various compound aluminum alloy dummy ingots are synchronously casted.

Description

technical field [0001] The invention relates to a multi-layer dissimilar aluminum alloy synchronous composite casting device, which belongs to the technical field of aluminum alloy semi-continuous casting. Background technique [0002] Aluminum alloy bimetal or three-layer metal composite sheet is an important material for manufacturing radiators and heat exchangers. It is widely used in industries such as automobiles, air conditioners, and oxygen generators, and has a very broad market prospect. At present, the production process of aluminum alloy composite plates in my country is to firstly prepare the core layer and cladding layer ingot blanks by direct water-cooling semi-continuous casting, and then carry out surface milling, hot rolling, and Cutting, pickling, alkali washing and other related treatments, and finally produce aluminum alloy composite plates by hot rolling and compounding.

AI Technical Summary

Problems solved by technology

[0003] Using this hot rolling composite process to prepare aluminum alloy composite panels not only has a long production cycle, many procedures, and high labor intensity, but also the composite interface is easily oxidized during the rolling composite process of the core layer and cladding layer, and the bonding strength of the metal composite layer is low.
