| 英文摘要: |
| Based on the research of the continuous grain flow crankshaft forging in the RR- equipment and TR- equipment, the problem of eliminating forging accessorial block was brought forward. Through careful analysis of the reasons for the formation and position of forging accessorial block on the cranks, some ways to eliminating the block were found. These new techniques were applied on making the 21/31 crankshaft and good effect was obtained. |
