【Abstract】 Large scale high manganese steel alligator board produced by EPC process can meet the request of design, and use with hot remained water toughening treatment. Owing to preventing the deformation and crack, the key factors of the angle?direction and speed of putting into water should be well controlled. From the statistics data of 100 castings, the deformation and crack have not been seen after controlling.更多还原
