Claim:
A method for hot rolling starting material ( 200 ) in a finishing train ( 100 ), which comprises the following steps: introducing the starting material ( 200 ), which is heated to a run-in temperature (T E ) above a predetermined lower temperature threshold value (T U ), into the finishing train; rolling the heated starting material ( 200 ) in several successive rolling stands ( 110 - n ) of the finishing train to form strip material, where the starting material undergoes cooling from the run-in temperature (T E ) due to heat losses in the finishing train ( 100 ); and compensating for the heat losses by reheating the material between at least some of the successive rolling stands ( 110 - n ) of the finishing train by using heaters ( 120 - k ) arranged between the rolling stands of the finishing train ( 100 ), to an extent that the temperature within the rolling train and the final rolling temperature (T A ) of the strip material when it leaves the finishing train ( 100 ) are not below the predetermined lower temperature threshold value (T U ); the compensating step including determining a first of the heaters, relative to a direction of material flow, at which or downstream of which the temperature of the material threatens to fall below the lower temperature threshold value (T U ) for a first time due to heat losses; then reheating the material so that the temperature of the material is increased by the first heater ( 120 - k ) only to an extent that the temperature falls to the lower temperature threshold value (T U ) due to given local heat losses in the finishing train during further conveyance of the material to a next heater downstream ( 120 -[k+1]) of the first determined heater, as seen in the direction of material flow, or if there is no further heater downstream in the direction of material flow, the temperature of the material is increased to a point at which the material leaves the finishing train ( 100 ); and repeating the reheating of the material by each additional downstream heater within the finishing train, as viewed in the direction of material flow.
