Abstract: |
Problems of rotary press modeling roughcast with cold shape correction are introduced during plate-welding and rotary press modeling processing of T250 steel chamber shell for solid rocket motor. Technological idea of rotary press modeling roughcast with hot shape correction is presented, the feasibility of which is theoretically analyzed and studied. The finished tests show that the set processing method is feasible. |
Key words: T-250 steel;chamber shell of solid rocket motor;hot shape correction |
