개소료고체화전발동궤T250강각체용판한선압공예성형시，선압모배랭교형존재적문제。제출료선압모배용열교형적공예사상，병대기가행성진행료이론분석여연구，경시험험증료해공예방법적가행성。
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.
