| titleOfInvention | GH4169 high-temperature alloy special-cross-section large annular piece liquid forging and rolling composite forming method |
| abstract | The invention discloses a GH4169 high-temperature alloy special-cross-section large annular piece liquid forging and rolling composite forming method which comprises the following steps: 1) smelting; 2) liquid forging: fixing a liquid forging mold on an indirect squeezing casting machine, pouring an alloy solution in constant volume into the liquid forging mold, wherein the pouring temperature is 1350-1400 DEG C, the pressurization speed is 35-40mm/s, the type filling time is 1-6 seconds, and the specific pressure is 350-400MPa; and keeping the pressure under the pressure for 35-90 seconds, thereby obtaining a near terminal cross section annular blank; 3) homogenizing: cooling the near terminal cross section annular blank to 1150-1160 DEG C, performing heat preservation for 20-30 hours, then rising the temperature to 1180-1190 DEG C, and performing heat preservation for 110-130 hours; 4) residue heat isothermal rolling: reducing the temperature of the near terminal cross section annular blank after homogenization to 1010-1120 DEG C, and carrying out residue heat constant temperature rolling on a radial and axial composite rolling annular machine; 5) heat treatment: performing heat preservation on the annular blank at a temperature of 715-725 DEG C for 8 hours, and then cooling to 615-625 DEG C in a furnace at a speed of 50 DEG C/h, performing heat preservation for 8 hours, and carrying out air cooling; and 6) finishing. |
