| Abstract: | This article expounds the forging process of 9Cr2Mo small size roller. The forging ratio of the last heat must not be less than 1.5, meanwhile the temperature of the final forging has to be controlled within 750～850℃ and fast cooling shall be performed after forging so that the large reticulate carbide can be released, which is advantageous to obtain better balling structure. |
