| Abstract: | The deposit-awl in the fluid entrance of the steel ingot to be used to manufacture large axis forgings is always a knotty problem, A new kind of technology called reverse squeezing with a flaw millstone was applied to settle this problem. The die laying , technological steps and characteristics, and economic benefits about the technology were detailed. And a site experiment was carried out to prove the correctness and feasibility of the technology. |
