Abstract The high-speed slab continuous casting has attracted more and more attention because of its advantages of reducing equipment investment, increasing production and efficiency and reducing material consumption. In order to solve the problem of matching the casting cycle and refining cycle of low carbon steel and further improve the production efficiency. Some steel plant has carried out the research on the high-speed continuous casting process technology of optimizing the electromagnetic braking parameters of the mold. After applying the magnetic field, with the increase of the upper coil current from Type A to Type C, the surface velocity of molten steel in the mold is reduced from 0.35 m/s to 0.21 m/s, the electromagnetic braking can significantly reduce the surface velocity at high casting speed. With the increase of argon blowing flow from 12 L/min to 20 L/min, the surface velocity of molten steel increases. With the increase of nozzle immersion depth, the flow field shape in the mold does not change significantly. The inclusion index at 2.05 m/min is significantly lower than that at 1.8 m/min.

Key words： high-speed continuous casting low-carbon steel electromagnetic brake inclusion FC mold numerical simulation
