Composite ingot set for continuous casting of Cu-Al bimetal in down-pulling reverse solidification process

Abstract

The continuous Cu-Al bimetal composite ingot casting set operating on down-pulling reverse solidification process has improved including effect and may be used in industrial production. The present invention includes one melting and maintaining furnace and one ingot drawing unit, and features that there are a crucible below the liquid outlet of the melting and maintaining furnace, a heating and temperature regulating unit outside the crucible, a crystallizer below the crucible, a ingot drawing unit below the crucible, a metal aluminum core mounted onto the dummy bar of the ingot drawing unit and located inside the crucible, a casting speed controller, and a vacuum chamber for all the melting and maintaining furnace, the crucible, the heating and temperature regulating unit, the crystallizer and the casting speed controller to be set inside. Copper as the coating material is smelted in the melting and maintaining furnace and coated to the aluminum core with the crucible and the crystallizer while the composite ingot is drawn out with the ingot drawing unit.

Description

technical field [0001] The invention belongs to a casting device, in particular to a pull-down reverse solidification method continuous casting copper-aluminum bimetal compound ingot casting device. Background technique [0002] Copper-clad aluminum bimetal composite wire is a new type of wire. It uses aluminum as the inner core and copper as the outer skin, that is, a layer of copper is concentrically coated on the aluminum core wire to form a copper-aluminum composite wire. This kind of wire does not affect the conductive performance, and can save a lot of copper. The finished wire can be widely used in CATV, mobile communication cables and other fields. The market prospect is huge, so it has been valued by all parties. [0003] At present, there are many methods of copper-clad aluminum in industrial production, and the most widely used method in China is the cladding welding method. The specific process is: the cleaned copper strip is gradually made into a circular tube ...
