For adjusting the burn-through point (D) in a sintering machine (1), in which the material to be sintered is charged onto a conveying path (3), ignited and transported past windboxes (6) arranged in conveying direction (F) up to a material dump (5), the temperature is measured at at least three measurement points (10) consecutively arranged along the conveying path (3) and the conveying speed of the sintering machine (1) is adjusted in dependence on the position of the maximum measured temperature (D(i)) relative to the position of the selected burn-through point (D) on the conveying path. The profile of the temperature of three consecutively arranged measurement points (10) is compared, wherein a maximum of the temperature is assumed when the first and third measurement points (10) in conveying direction (F) have a lower temperature value than the second measurement point (10), and wherein no maximum of the temperature is assumed when all measurement points (10) form an ascending series of temperature values. With an assumed maximum of the temperature, the conveying speed is adjusted in dependence on a deviation between the position of the measurement point with the maximum temperature value (D(i)) and the position of the selected burn-through point (D), whereas with no assumed maximum of the temperature the conveying speed is reduced by a specified value. |
