“…Wang Hui et al [ 8 ] found that there is a process of mutual promotion between carburization and oxidation of the Cr35Ni45 steel furnace tube through the study of its oxidation mechanism in long-term service. Du Chen-yang et al [ 9 , 10 ] studied the detection method of carburization damage of cracking furnace tube based on a magnetic analyzer, ultrasonic guided wave, low-frequency electromagnetism, and other technical means, which provides a new method and means for the practical engineering application of carburization damage of cracking furnace tube. Stamatis A. Sarris [ 11 ] and others studied the effect of oxidation on the coking of furnace tubes and found that the oxide of Cr can play an anti-coking role.…”
