摘要： PURPOSE: A steel sheet cooling method is provided to reduce scale during a water cooling process, thereby enabling transformation to a lower temperature structure through rapid cooling without an additional pickling device. CONSTITUTION: A steel sheet cooling method is characterized in that a CxHx based non-oxidizing material is sprayed on a steel sheet having a temperature over 600°C to cool the steel sheet. The non-oxidizing material is one or two selected from the group consisting of pentane(C5H12), hexane(C6H14), heptane(C7H16), and octane(C8H18). The steel cooling method employs a continuous annealing line or continuous hot dipping line.
