Experimental method for measuring temperature field in sintering process

The invention relates to the technical field of iron and steel smelting, and provides an experimental method for measuring the temperature field in the sintering process. The method includes the following steps: dosing, wetting, rotary drum granulation, screening and high-temperature sintering. The thickness and the temperature of a combustion zone and the shrinkage of a material bed in the sintering process are measured in real time through a transparent sintered cup experiment assisted infrared thermometer, and the mineralization temperature of a sintered cake is determined by using a relative coordinate technology, that is, the temperature distribution of the sintered cake in a height direction in the sintering process is different from finite element simulation. The method can well describe the actual sintering process. The temperature field of the sintering process can be obtained, and the change of the liquid phase amount, the liquid phase component, the solid phase amount and the solid phase component
