A method and an arrangement for rolling hot wide strips from continuously cast thin slabs in successive steps of operation of a rolling line which includes a continuous finishing train. One or more casting lines and individual thin slabs are severed from the cast strand. The thin slabs are homogenized and adjusted to rolling temperature in an equalizing furnace and the thin slabs are transferred from the equalizing furnace to the rolling line. Roller-type turning furnaces provided in each of the casting lines and in the rolling line are use by turning the roller-type turning furnaces toward each other into positions which are inclined relative to the casting and rolling lines in the manner of switches for alternatingly conveying thin slabs from one of the casting lines through the roller-type turning furnaces into the rolling line.
