Embodiment 1
[0041] A die forging method for a deformed superalloy blade forging, comprising the following steps:
[0042] S1. Planetary polishing: put the qualified nickel-based superalloy GH4169D bar into the centrifuge, the water level is 2-3cm higher than the abrasive and forging, and the polishing time is 10min to remove the machining burr and surface dirt of the bar;
[0043] S2, visual inspection and spraying lubricant: put the GH4169D bar stock after planetary light decoration in step S1 into an oven, heat the furnace temperature to 120 ° C, and heat up for 60 minutes, then take out the bar stock spraying glass lubricant from the oven, The thickness of the coating is 0.10±0.02mm. After spraying, place it at room temperature for at least 1 hour to obtain a bar material sprayed with glass lubricant;
[0044] S3. Extrusion heating: put the rod in step S2 into a furnace for heating, the furnace temperature is 950° C., and the holding time is 60 minutes.
[0045] S4. Extrusion: The ext...
Embodiment 2
[0053] A die forging method for a deformed superalloy blade forging is carried out according to the method in Example 1, the difference is that:
[0054] S3. Extrusion heating: put the bar material in step S2 into a furnace for heating, the furnace temperature is 1100° C., and the holding time is 10 minutes.
[0055] S4: Extrusion: The extrusion ratio is 9. Quickly take out the bar from the forging furnace and put it into the extrusion die of the screw press, put the chamfered end downward into the extrusion mold, and quickly strike for extrusion molding to obtain For extruded parts, the total time for billet out of the furnace, transfer and forging shall not exceed 15 seconds, and the extruded parts shall be taken out and cooled;
[0056] S8. Heating for final forging: put the extruded part in step S7 into a furnace for heating, and the furnace temperature is 1060° C. when the furnace is put into the furnace, and the holding time is 5 minutes;
[0057] S9. Final forging: Qui...
Embodiment 3
[0059] A die forging method for a deformed superalloy blade forging is carried out according to the method in Example 1, the difference is that:
[0060] S3. Extrusion heating: put the rod in step S2 into a furnace for heating, the furnace temperature is 1060° C., and the holding time is 25 minutes.
[0061] S4: Extrusion: The extrusion ratio is 6. Quickly take out the bar from the forging furnace and put it into the extrusion die of the screw press, put the chamfered end downward into the extrusion mold, and quickly strike for extrusion molding to obtain For extruded parts, the total time for billet out of the furnace, transfer and forging shall not exceed 15 seconds, and the extruded parts shall be taken out and cooled;
[0062] S8. Heating for final forging: put the extruded part in step S7 into a furnace for heating, the furnace temperature is 1030°C during furnace charging, and the holding time is 15 minutes;
[0063] S9. Final forging: Quickly take out the extruded part...
