Infrared thermal camera can monitor sintering machine in all aspects

The special thermal imaging temperature monitoring system for the sintering machine of infrared thermal camera can solve the following problems:

1) The maximum temperature distribution of sintering machine section and temperature curve changing with time;

2) Longitudinal temperature distribution of sintering machine section and temperature curve changing with time;

3) The tail section of the sintering machine and the relative position of the red tropics of the sintering table and their changing trend with time;

4) Relative width and variation trend of red tropics over time;

5) Relative burning degree of mixture layer and change trend with time;

6) Establish a sinter quality prediction model;

7) The drum strength and FeO content of sinter are predicted online, and the trend of these sinter quality indexes changing with the production process is given to provide basic information for adjusting and optimizing sinter quality.

Infrared thermal imager can provide important technical basis for the whole process intelligent control

Sintering machine is according to certain proportion coordination of iron ore powder and solvent, powder, granule solid fuel after adding water mixing system grain of tile in sintering machine such as the car, and then the ignition, on the surface of the material at the bottom of the layers in convulsions at the same time, the coal layer surface is lit solid fuel combustion zone, with the help of high temperature burning, the sintering raw materials will occur between the composition of the corresponding physical and chemical changes, and partial melting or softening and generate a certain amount of liquid phase, particles will not melt the stick into pieces, each other become the sinter.

With the completion of upper solid combustion, it marks the completion of sintering process, which is also one of the most important monitoring Windows of sintering quality information. It is of great significance to control and optimize sintering process and sinter quality by obtaining infrared thermal image of sinter tail section and judging sinter temperature distribution information of sinter tail section.
