HOT ROLLING METHOD OF FERRITE STAINLESS STEEL WITH HIGH ANTI-RIDGING AND ANTI-STICKING PROPERTIES

摘要

PURPOSE: A hot rolling method of a ferrite stainless steel with high anti-ridging and anti-sticking properties is provided to promote recrystallizing environment of a complex organization of ferrite or austenite by decreasing a rear part rolling temperature by spraying cooling water while increasing the rolling speed, thereby improving the ridging and reducing a coefficient of friction between a workpiece and rolling rolls for preventing sticking defect. CONSTITUTION: In a hot rolling method of a ferrite stainless steel with high anti-ridging and anti-sticking properties for carrying out hot rolling of a ferrite stainless steel sleeve by inserting between a plurality of hot rolling rolls (12) of a hot rolling machine (10), cooling water is sprayed onto the steel plate at least at one position before advancing the steel plate to a rolling roll of a last stage of the hot rolling machine for maintaining a surface temperature of the steel plate at 835-875°C, wherein the cooling water is sprayed in front of a third hot roll from the last hot rolling roll for maintaining the surface temperature of the steel plate at 948-960°C.
