And a rolling material cutting device is also arranged at each rolling port, and consists of rolling cutters and hydraulic cylinders for driving the rolling cutters to move relatively, wherein the hydraulic cylinders are connected with a hydraulic control system, and the hydraulic control system is electrically connected with an integrated control system, namely the integrated control system can control the opening or closing (releasing or cutting off the bars) of each rolling cutter.
And each group of rollers is also provided with a hydraulic cylinder capable of controlling the distance between the rollers, the hydraulic cylinders are also respectively connected with the hydraulic control system and can be controlled by the integrated control system, namely the integrated control system can control the distance between the rollers of the rolling mills in each group of rolling mills, thereby controlling the diameter of the bar material output from the rolling mills.
An embodiment includes the following steps:
s1, continuous casting: preparing a continuous casting billet;
s2, continuous casting machine: inputting a continuous casting blank into a continuous casting machine and outputting a bar material by a continuous casting machine;
s3, drawing: straightening the bar through a straightening mechanism and drawing the bar onto a transmission guide rail;
s4, transmission: the bar is conveyed to a rolling mill unit by the conveying mechanism;
