| Abstract: | The deposit cone in the fluid entrance of the steel ingot to be used to manufacture heavy axis kind forgings is always a knotty problem.Reverse squeezing with flaw millstones tries to seek after a way to solve this problem.In this paper,the dies laying,technology steps,technology characteristics and economic benefit of this technology are list to the point.And the technology experiment was carried out to prove the correctness and feasibility.Besides,with numerical simulation the technology is researched from the three aspects reverse squeezing course,point tracking and load of dies.And the correctness and feasibility of the technology are testified further. |
