PROBLEM TO BE SOLVED: To provide a light rolling reduction control system for a continuously cast slab and a method therefor capable of performing the practice of thermal rating independently of a host computer, in which data required for casting are stored, and improving a control precision. SOLUTION: In a continuous casting apparatus where a plurality of light rolling reduction rolls are arranged in the vicinity of the final solidified region of a continuously cast slab, and the intervals between the respective rolls are made respectively independently controllable, a thermal tracking system 4 where a calculation model in which, within a strand under casting, calculated cross sections vertical to the casting direction are generated at prescribed intervals, and, as holding cooling history information based on two-dimensional solidifying calculation at the time when the respective calculated cross sections pass through a plurality of cooling zones, the slab solidified conditions in the regions at which the light rolling reduction rolls are arranged are estimated is applied to a server client method using a general purpose commercial computer, and a host computer 1 performing the control of the continuous casting equipment body and the storage of steel kinds and operating parameters are independently arranged.
