| Abstract: | Microstructure and properties of GH4648 alloy bar rolled by hot continuous rolling production line was studied.It was found that the hot-rolling bar with uniform grains and suitable α-Cr phases can be rolled by the controlling of both rolling and finishing temperature,which can be controlled by automation control system in the hot continuous rolling process.Compared with that by the open-train mill,the hot-rolling bar with stable microstructure and improved properties can be obtained by the hot continuous rolling production line. |
