| Abstract: | The experiment is studied by testing of heating temperature, finish rolling temperature on 51CrV4 hardness of the impact of hot-rolled in the continuous rolling production line, to explore the process of lowering hardness of hotrolled fiat steel spring about 51CrV4. Derived when heating temperature is 1 100 ± 20 ℃, finish rolling temperature is 880 -920 ℃ , the hot finisher speed is 3.5 m/s, then the hot hardness reaches the standard. |
