Abstract

The invention discloses Cu-Fe composite material double-melt mixed casting equipment and technology. The Cu-Fe composite material double-melt mixed casting equipment comprises a first melting furnace,a second melting furnace, a mixing cavity, an induction heater, a crystallizer, a stopper rod mechanism and an air pressure adjusting mechanism, wherein the first melting furnace is used for heatingand melting pure Cu, the second melting furnace is used for heating and melting a Cu-Fe alloy, the mixing cavity communicates with liquid outlets of the first melting furnace and the second melting furnace through guide pipes, the heated and molten pure Cu and the heated and molten Cu-Fe alloy are mixed, the induction heater is used for heating and electromagnetically stirring a mixed melt in themixing cavity, the crystallizer is in butt joint with a liquid outlet of the mixing cavity, the stopper rod mechanism is used for controlling opening and closing of the liquid outlets and the melt flow of the first melting furnace and the second melting furnace, and the air pressure adjusting mechanism is used for adjusting air pressure in the first melting furnace and the second melting furnace.The casting equipment and the process not only solve the problem that the composition and the structure of a Cu-Fe composite material are uneven in the casting process, but also obviously improve theproduction efficiency, reduce the production cost, and are suitable for industrial scale production.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a Cu-Fe composite double-melt mixed casting equipment and process. Background technique [0002] The Cu-Fe composite material combines the high electrical conductivity and thermal conductivity of Cu with the soft magnetic properties, high strength and stiffness of Fe, and has unique electromagnetic shielding properties. It is widely used in pulsed strong magnetic field systems, particle acceleration electromagnetic launchers, High-energy synchrotron radiation light sources and other high-tech fields. [0003] During the solidification process of Cu-Fe composites, two kinds of liquid phase regions will be formed, namely the Cu-rich region (L 1 ) and Fe-rich region (L 2 ). Due to the different composition of the two liquid phases, the Stokes motion caused by the density difference leads to macrosegregation under the action of the gravity field,...
