Disclosed is a method for controlling the layer thickness of a sintering starting material for a sintering machine, which properly controls the layer thickness of the sintering starting material on the entry side of the sintering machine. The pre- and post-ignition furnace layer thickness on the ignition furnace entry side and the ignition furnace exit side for the sintering starting material upon a palette is detected while the palette conveyance speed of the aforementioned palette and the feeder rotation speed of a drum feeder are detected, and a gate opening command for a split gate is obtained on the basis of: a gate opening reference value for the aforementioned split gate, which was obtained from the aforementioned ignition furnace entry-side layer thickness, a first opening correction value based on the aforementioned palette conveyance speed and the aforementioned feeder rotation speed, and a second opening correction value based on the amount of decrease from the size of the sintering starting material layer at the initiation of ignition and absorption, which was obtained from the aforementioned ignition furnace entry-side layer thickness and the aforementioned ignition furnace exit-side layer thickness. |
