Rolling method capable of reducing as-rolled hardness of 42CrMo steel
The invention relates to a rolling method capable of reducing an as-rolled hardness of 42CrMo steel. The rolling method comprises the following steps: (1) carrying out heating treatment on a blank of the 42CrMo steel; and (2) sequentially carrying out rough rolling, medium rolling and finish rolling...

| description | The invention relates to a rolling method capable of reducing an as-rolled hardness of 42CrMo steel. The rolling method comprises the following steps: (1) carrying out heating treatment on a blank of the 42CrMo steel; and (2) sequentially carrying out rough rolling, medium rolling and finish rolling on the treated blank of the 42CrMo steel to obtain the 42CrMo steel with a low as-rolled hardness. The rolling method capable of reducing the as-rolled hardness of the 42CrMo steel, which is disclosed by the invention, has the following beneficial effects: 1. a low finish rolling temperature is controlled, a high pressure stress on the core part of the steel is achieved during a rolling process, structure uniformity is greatly improved, and grains are further refined; and 2. the finish rolling temperature is lowered to be approximate to an actual critical phase change point (Ar3), thus phase change of the 42CrMo steel from phase gamma to phase alpha is promoted, finally an as-rolled structure is a balanced ferrite |
