| Abstract: | A new grade ZGMnl3Mo was selected to improve the welding performance of the ordinary high-manganese steel in the large excavator. Molding material, pouring temperature, alloying and heat treatment process have been changed to find the optimal combination by orthogonal test method. The production has been proven these measures can control chemistry burnt-on sand defect, refine the grain, improve the life and ensure the quality of high - manganese steel castings. |
