| description | The embodiment of the invention provides a double-high-speed bar temperature control rolling method. The double-high-speed bar temperature control rolling method comprises the steps that a rough rolling procedure, an intermediate rolling procedure, a pre-finish rolling procedure, a finish rolling procedure, a diameter reducing procedure and a fixed-length shearing procedure are sequentially carried out; wherein a first controlled cooling process is arranged between the pre-finish rolling process and the finish rolling process; and a second controlled cooling process is arranged between the finish rolling process and the diameter reducing process. According to the technical scheme, the multi-stage controlled cooling rolling technology is adopted, the temperature of a rolled piece is always controlled in an austenite and ferrite two-phase area in the controlled cooling process, and therefore a closed-loop tempering structure is effectively prevented from being formed on the surface of the finished deformed stee |
