PURPOSE: A steel sheet manufacturing method is provided to prevent a failure due to overcooling at the edge of a material by maintaining uniform temperature distribution of the material. CONSTITUTION: A steel sheet manufacturing method comprises the steps of: extracting a material(S) from a heating furnace(102) and air-cooling the material, roughly rolling the material through multiple passes(2N+1, N=1,2,..., n) wherein the material is queued before the final pass(N=n), finally rolling the material, and coiling the rolled material. |
