▎ 摘　　要

NOVELTY - The device has a melting casting system (3), a melt runner (5), a centrifugal casting mold (7), a centrifugal casting baffle (6), a centrifugal mold heater (8), a reactive gas injection pipe (9), a first infrared thermometer (12) and a second infrared thermometer (14). The melting casting system heats the main metal material and the other alloying element bar (2) to melt. The outlet of a melt dropping pipe (3-3) of the smelting casting system is located on the upper side of the melt runner. The melt runner is located obliquely, and the lower end is located in one end opening of the centrifugal casting mold. The driving device drives the centrifugal casting mold to rotate under the control of the control device. The first and second infrared thermometers are connected to a signal input end of the control device. A control device is configured to control the centrifugal mold heater to operate according to the temperature measured by the first and second infrared thermometers. USE - Graphene composite material preparation device. ADVANTAGE - The device performs the preparation of the graphene-bismuth metal-based multilayer composite material by multiple centrifugation and solidification, has short preparation time, low energy consumption, and low preparation equipment, and is favorable for large-scale production and promotion. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of graphene composite material preparation device.
