PROBLEM TO BE SOLVED: To provide a method for controlling pallet speed in a sintering machine with which the pallet speed can be controlled with good followability by compensating a time delaying characteristic in a temperature measuring means, in the sintering process. SOLUTION: In the pallet speed control method for controlling speed of the pallet 3 when sintering raw material 20 is supplied on the pallet 3 in the sintering machine and carried to an ore discharging part, exhaust gas temperature is measured with thermocouples 5 set in a plurality of wind boxes 4 in the machine length direction, and the time delaying characteristic of the measured temperature is compensated with a reverse filter 6. The burning point is assumed based on the relation between the wind box position in the machine length direction and the exhaust gas temperature at an BTP assumption part 7 based on the output of the reverse filter 6, and a deviation between the target value set at a target value setting part 8 and the assumed burning point, is inputted to a PID control part 10, and thus a driving motor 11 is controlled.
