The method for rolling the steel slab to thick plate, comprises controlling the camber which is one of defects generated in the flatness of the thick plate. When the steel slab is rolled through a plurality of paths, the roll gap of the primary path satisfies the following equations: SWi = SWi*+1/2Lrhi {&phgr;i-1-(Pi-1/ξi&lgr;2)} and Sdi=sdi*+1/2Lrhi{&phgr;i-1-(Pi-1/ξi&lgr;2)}, where Swi is a set amount Swi* and Sdi* is the set amount of roll gap at i-path rolling step, Lr is adistance between loading points of the rolling mills, and hi is an average steel-plate thickness in i-path rolling step.
