HOT ROLLING METHOD FOR PREVENTING STICKING DURING FINISHING HOT ROLLING OF STAINLESS STEEL

摘要

PURPOSE: A hot rolling method for preventing sticking during finishing hot rolling of stainless steel is provided to manufacture hot rolled stainless steel sheet having superior quality by installing a high frequency induction heating equipment at the exit side of a rough mill, thereby forming scale layer serving as lubricant layer on the surface of a material to be rolled. CONSTITUTION: The hot rolling method for preventing sticking during finishing hot rolling of stainless steel comprises the processes of installing a high frequency induction heating equipment(40) at points that are 100 to 400 mm distanced from both edges of upper and lower parts of the strip (S) at the exit side of rough rolling rolls(21-24) of a rough mill(10) in a hot rolling plant for producing stainless strip; heating a stainless strip to be rolled to 1200 to 1300 deg.C using the high frequency induction heating equipment(40) operated in the range of 40 to 50 kw; and forming appropriate scale layer on the surface of the stainless strip to be rolled before the stainless strip to be rolled is rolled by finish hot rolling rolls(31-33) of a finish hot rolling stand(30) so that the scale layer functions as a lubricant between the rolls and the stainless strip to be rolled during rolling of the stainless strip to be rolled (S).
