Abstract: 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%.
