| Abstract: | The chemical ingredient range of Cummis exhaust pipe was ascertained by production tests.The thin-walled cast of non-ionization QT400-15 was successful to realize the production in as-cast state by the effective nodulizing treatment process and thrice compound inoculants,its property attained the goal: percent of spheroidization > 85%, percent of ferrite 95%. The working procedure of the heat treatment was released. |
