[0039] refer to figure 1 , figure 1 It is a schematic flow chart of a dummy rolling method for thin slab continuous casting and rolling in an embodiment of the present invention.
[0040] In this embodiment, the dummy rolling method of thin slab continuous casting and rolling is applied to an industrial computer, and the method includes:
[0041] 1) Steelmaking: molten steel is obtained through conventional smelting;
[0042] 2) Thin slab continuous casting: casting the molten steel into a slab through a thin slab continuous casting machine, controlling the casting speed of the thin slab continuous casting machine to be 4.8-5.5 m / min, and controlling the thickness of the slab to be 50 ~55mm, control the temperature of the slab entering the soaking furnace to exceed 950°C;
[0043] 3) Soaking: Soaking the slab through the soaking furnace, controlling the time of the slab in the furnace to exceed 40 minutes, the temperature deviation of the same plate does not exceed 5°C, and...
