The invention discloses a detection method of heated intensity of a sintered material surface in an ignition furnace, and belongs to the technical field of sintering. The detection method of the heated intensity of the sintered material surface in the ignition furnace comprises the steps of detecting temperatures of the sintered material surface in the ignition furnace through a thermocouple, andsending a temperature signal to a temperature controller through the thermocouple; drawing a material surface temperature change curve according to the temperature signal received by the temperature controller; obtaining comprehensive heated intensity of the sintered material surface in a high-temperature area according to absolute heated intensity and operation running of a sintering pallet in the high-temperature area in the ignition furnace; obtaining comprehensive heated intensity of the sintered material surface in a medium-high temperature area according to absolute heated intensity andoperation running of a sintering pallet in the medium-high temperature area in the ignition furnace;obtaining ignition quality of the sintering ignition furnace according to the comprehensive heated intensity in the high-temperature area and the comprehensive heated intensity in the medium-high temperature area of the sintered material surface. According to the detection method of the heated intensity of the sintered material surface in the ignition furnace, the ignition quality of the sintering ignition furnace can be judged and estimated in a quantitative mode.
