METHOD FOR HOT ROLLING STAINLESS STEEL

摘要

PURPOSE: A method for hot rolling stainless steel is provided to guide inhomogeneous transformation produced inside a rolled plate of stainless steel into homogeneous transformation by rough rolling and finish rolling the rolled plate after securing transformation resistance in the rolled plate of stainless steel in the hot rolling process. CONSTITUTION: The method further comprises the step of maintaining a surface temperature of the rolled plate (2) to a hot rolling temperature of 800 deg.C or less right before the rolled plate (2) passes through the rolling roll (3) in a method for hot rolling by passing a rolled plate of stainless steel through a plurality of rolling rolls, wherein cooling water is sprayed toward the surface of the rolling plate charged into the rolling roll at an angle of 10 to 20 degrees, and the rolled plate passes through the rolling roll within 2 seconds after the cooling water is sprayed on the surface of the rolled plate.
