Problems solved by technology

[0003] The invention overcomes the deficiencies in the prior art. The low-temperature oxidation reaction is an exothermic reaction, which causes the internal temperature of the sand-filling model to be higher than the external temperature of the sand-filling model. The external temperature of the existing sand-filling model is mainly affected by the constant temperature system, which cannot Compensate the external temperature of the sand filling model, resulting in the external temperature of the sand filling model being lower than the internal temperature of the sand filling model during the low temperature oxidation experiment, providing a temperature compensation system for low temperature oxidation intelligent detection, which can realize the low temperature oxidation experiment process The consistency of the internal and external temperatures ensures that the external temperature of the model can be compensated in time during the low-temperature oxidation experiment, and ensures that the external temperature of the low-temperature oxidation model can increase with the increase of the internal temperature, thereby ensuring the consistency of the internal and external temperatures of the model
