First, the opening of the casting mold (8) is sealed with a sealing plate (12), and then the metal liquid is added into the casting mold (8) from the feeding pipe (16); S2, the motor (3) then drives the annular frame (7) and the casting mold (8) to rotate, so that the metal liquid in the casting mold (8) fills the gap in the casting mold (8) in a centrifugal state; S3, after the casting mold (8) rotates for a certain period of time, the motor (3) stops driving the casting mold (8) to rotate, and then the hydraulic expansion unit 1 (21) drives the box body 2 (22) to move upward, so that the casting mold (8) contacts the water in the box body 2 (22), thereby quickly cooling the casting mold (8) and accelerating the cooling speed of the metal liquid in the casting mold (8); S4, the closing plate (12) is then moved inwardly so that the opening of the casting mold (8) is opened, and then the heat-insulating pusher block (15) is driven by the electric telescopic unit (13) to push out the steel back formed inside the casting mold (8) and drop it into the inside of the box body (22); S5, push plate 1 (27) moves backward to push the steel back, then push plate 1 (27) moves to the front, and then push plate 2 (30) moves rightward to push the steel back to the inner right area of ​​box body 2 (22), so that the staff can remove the steel back easily.

10. The centrifugal casting method of a centrifugal casting device for a brake steel back for high-speed railway braking according to claim 9, characterized in that: The S1 also includes the following steps: S11. After the molten metal enters the casting mold (8), the electric telescopic unit three (17) drives the scraper cone (20) to move above the feed pipe (16), and then the electric telescopic unit four (19) drives the scraper cone (20) to move downward to scrape off the molten metal on the inner wall of the feed pipe (16).
