Abstract: A screw smelting machine melts raw materials with a different chemical ratio in a mixing funnel in a feeding order to prevent the long-range diffusion of a melt, and controls outflow at a suitable speed. A centrifugal casting machine solidifies the melt with the ingredients gradient varying into a radial ingredient gradient material by a centrifugal casting style. A temperature sensor monitors temperature of an outer surface of a centrifuge cavity of the centrifugal casting machine during centrifugal casting, and transmits the temperature to a control platform. The control platform determines an optimal flow rate of the melt at an end of screw rod according to ingredient gradient of ingredient radial-gradient pipe materials and a thickness of each component gradient material required with preparation, in combination with a real-time data fed back from the temperature sensor, and feeds back to a feeding end.
