【Abstract】 Causes to the crackings on the sealed head of 1Cr18Ni9Ti cleavage furnace have been analyzed by an optical microscope and an electronic scanning probe-energy spectrograph.Results show that crackings of the sealed head are caused by expansion of the inter crystalline corrosive cracking and recarburization in the inner wall of the sealed head is the primary factor to the inter crystalline corrosive cracking.更多还原
