Embodiment 1
[0028] A kind of Fe-Cr-Zr series ferritic heat-resistant alloy described in this example, the mass fraction of each element of alloy is as follows: C: 0.0039%, Cr: 8.96%, W: 2.01%, Zr: 9.5%, surplus is Fe.
[0029] The specific production process steps are as follows:
[0030] 1) Melting: Weigh the raw materials according to the alloy composition ratio, put the prepared raw materials into the crucible of the vacuum induction melting furnace, melt them in the vacuum induction furnace, and cast them into ingots. After the ingots are completely solidified, open the mold and take them out ;
[0031] 2) Forging: Heat the ingot to 1200°C, keep it warm for 1 hour, quickly place it on a hammer forging machine to forge into a slab, then air cool to room temperature, and the final forging temperature is above 900°C.
[0032] 3) Rolling: heat the forged plate to 1200°C, keep it warm for 1 hour, roll it into a plate in a two-roll hot rolling mill, then air cool to room temperature, and ...
