中心压实锻造法生产工艺的改进

Improvement of J.T.S Forging Process in Production

运用高温云纹法模拟技术,对中心压实锻造法(J·T·S)现行生产工艺进行实验研究,提出了改进意见。实验结果表明:温度梯度合理选择范围为230～270℃;对称锻压锻件4个面,压下率均为7％～8％,并保证错砧;对某些锻件也可只锻压其垂直两面,压下率为13％左右;拔长方向最佳砧宽比为0.6。改进工艺可降低能耗20％～25％,节省操作时间约40％,降低压机吨位23％～43％。

J.T.S forging process is investigated for improving in current production by high temperature moire modelling technique. Some suggestions which can be used for improving current production are put forward. The rational range of temperature gradient is 230℃~270℃. The reduction rate is 7%~8% on each side for fourfold side symmetrical forge piece. The reduction rate is 13% that can be used for vertical two side unsymmetrical forge piece, The optimun of anvil width ratio (W1/H0) is 0.6, The improving J.T.S forging process can decrease the consumption of energy 20%~25%; It can save operating time 40%; and decrease the deformation load 23%~43%.
