| titleOfInvention | A kind of anti-coking alloy material processing method |
| abstract | The invention discloses a kind of processing method of anti-coking alloy material, and low oxygen partial pressure atmosphere processing is carried out to anti-coking alloy material, and surface anti-coking, impervious carbon protective film are formed in alloy material；Described low oxygen partial pressure atmosphere gas includes oxidizing gas and reducibility gas and/or inert gas；The anti-coking alloy material is made up of Cr, Ni, C, Fe, Mn, Si and trace element, wherein trace element is selected from least one of Al, Nb, Ti, W, Mo and rare earth element；In described alloy material, Cr content is：20 50wt%；Mn and Si content (wt.%) while meet following relation in the alloy material： 2.0 ≤ [ Mn ] × [ Si ] ≤ 4.0 [ Mn ] ≥ 1.0 [ Si ] ≥ 1.0 The present invention directly can form complex oxide film in common hydrocarbon cracks atmosphere in anti-coking alloy material surface, and film is thin continuous, and chemical stability is high in high-temperature coking atmosphere. |
