Description

Technical Field

[0002] The appropriate temperature can ensure good fluidity of molten steel and uniformity of the final casting. Therefore, monitoring the temperature of molten steel can ensure product quality and improve production efficiency. The method of monitoring the temperature of molten steel in the prior art is: using a radiation pyrometer to measure the temperature of molten steel in a non-contact manner and monitor the measured temperature.

[0003] However, the above method also has the following technical problems:

In addition, the measurement results of radiation pyrometers are highly dependent on the emissivity of the object being measured. If the emissivity of the object being measured is unknown or changes, it will directly affect the accuracy of the measurement results. Since the emissivity of molten steel may change under different conditions (such as composition changes, surface oxidation, etc.), the temperature of the molten steel measured by the above method has low accuracy, and monitoring the temperature will reduce product quality and production efficiency.

[0015] S6. Let count=count+1, a=c 0 、b=d 0 So that count, a and b are updated and the process goes to step S2.
