Embodiment 1
[0028] A rolling process for improving the as-rolled structure of 38CrMoAl steel comprises the following steps:
[0029] (1) Selection of 38CrMoAl steel billet: select the end face 250×280mm continuous casting billet as the 38CrMoAl steel billet;
[0030] (2) Billet heating: raise the temperature of 38CrMoAl steel billet to 1160-1180°C at a rate of 600°C / h, and keep it for more than 1.5h; , to ensure that the 38CrMoAl steel billet is completely evenly fired and then released from the furnace;
[0031] (3) Billet Rough Rolling: The 38CrMoAl steel billet after being released from the furnace is descaled by high-pressure water and then rolled into a Φ135mm process circle by 7 rough rolling racks; Total rolling deformation > 79%;
[0032] (4) Intermediate rolling of steel billet: Φ135mm process circle is carried out intermediate rolling after passing through the heat preservation roller table; the intermediate rolling adopts two-roller continuous rolling, and the process tempera...
