Failure Analysis on Furnace Tube of Fertilizer Plant
Feng Yao-rong · Inner Mongolia Petrochemical Industry · 2011
In this paper,the performance and chemical composition of furnace tube are tested,and by microstructure analysis,EDS analysisontain we found out the failure reason of the furnace tube.The furnace blast is it encounted high temperature suddenly in the service process,and it caused the microstructure of furnace tube has emerged reticular σ phase,and the σ phase is so low intensity and low toughness,so the blast is caused.
