摘要： PROBLEM TO BE SOLVED: To achieve a stable winding even over a wide range of a sheet thickness in a coil circulating and cold rolling method and coil circulating and cold rolling equipment.SOLUTION: A set sheet thickness determining function 41 inputs 5.0 mm of a sheet thickness after a first pass is finished from a rolling schedule, determines that the sheet thickness is not less than 4.0 of the set thickness, and outputs a command to a grip type winding controlling function 42 (step S41). The grip type winding controlling function 42 performs control based on a grip type (step S42). After the N-th pass is finished, if a sheet thickness of a buildup coil 31 is less than 4.0 mm (for example, 3.5 mm), the set sheet thickness determining function 41 inputs 3.5 mm of a sheet thickness after the N-th pass is finished from the rolling schedule, determines that the set sheet thickness is less than 4.0, and outputs a command to a belt wrapper type winding controlling function 43 (step S41). The belt wrapper type winding controlling function 43 performs control based on a belt wrapper type (step S43).
