| Abstract: | Laiwu Steel developed the American standard H13 Hot Die Steel and optimized its forging process. The optimized forging process adopted three-heating forming at the temperature of 1 260 ℃. To improve the compaction effect in the center of forgings,anvil width ratio,aspect ratio and other parameters are reasonably controlled in the forging process. Fast cooling after forging and rational spheroidizing annealing inhibits the net carbide precipitation and obtains the homogeneity of the structure. The technical indexes of the forgings fully meet the technical requirements. |
