摘要
The method for manufacturing a high-manganese steel cast slab according to the present invention includes manufacturing a cast slab by continuously casting a molten high-manganese steel having a specific chemical composition. In the manufacture, in a continuous-casting machine or during transportation before subsequent charging into a heating furnace for hot rolling, a processing strain is applied to the cast slab having a surface temperature of 600° C. or higher and 1100° C. or lower in such an amount that a processing strain amount calculated by a certain formula is 3.0% or more and 10.0% or less.
