This utility model relates to a turbid circulating water pressurization system for a finishing mill, belonging to the field of mechanical equipment technology. It includes a main inlet pipe, the outlet of which is connected to the cooling circuit of the finishing mill. A centrifugal pump is installed on the main inlet pipe, driven by a variable frequency motor. The centrifugal pump pressurizes the turbid circulating water and pumps it into the cooling circuit of the finishing mill. An inlet butterfly valve, an inlet pressure gauge, and an inlet pressure sensor are installed on the inlet side of the main inlet pipe, and an outlet butterfly valve, an outlet pressure gauge, and an outlet pressure sensor are installed on the outlet side. The inlet pressure sensor, outlet pressure sensor, and variable frequency motor are connected to a PLC control cabinet. The inlet and outlet pressure sensors detect the water pressure at the inlet and outlet of the main inlet pipe and feed it back to the PLC control cabinet. Upon receiving the signal, the PLC control cabinet adjusts the speed of the variable frequency motor. This application can locally increase the turbid circulating water supply pressure of the finishing mill rolls, improve the cooling effect of the roll rings, and ensure the surface hardness of the roll rings.

The utility model discloses a kind of anti-deviation steel strip rolling device, it is related to steel strip rolling technical field.The utility model includes bottom box, the bottom box top side is fixedly connected with rolling frame, the rolling frame inside is fixedly connected with bottom roll, the bottom roll rear side is fixedly connected with drive box, the rolling frame inside is threadedly connected with adjusting lever, the adjusting lever bottom is movably connected with top roll by bearing.The utility model is designed by anti-deviation roller of conical body shape, when steel strip deviates, its inclined plane is contacted with steel strip edge, because the linear velocity gradient of roll surface changes along axial direction and forms asymmetric lateral friction force, restoring force pointing to rolling center is generated, drive steel strip automatic return normality.Anti-deviation roller is driven by second driving motor, keeps same direction rotation, avoids shear stress caused by reverse rotation, reduces steel strip edge scratch, indentation and edge curl risk, significantly improves rolling precision and product quality.

The limiting device comprises a base plate installed on a hot rolling mill body, a sliding groove is formed in the base plate, a two-way lead screw is rotationally connected into the sliding groove, connecting blocks are connected to two sections of rod bodies, opposite in thread turning direction, of the two-way lead screw in a threaded mode, and the connecting blocks are slidably connected into the sliding groove. A limiting plate for limiting the steel plate is arranged on the connecting block, and an operation assembly for driving the bidirectional lead screw to rotate is arranged on the base plate. The effect of improving the rolling quality of the hot mill is achieved.

The application discloses an abnormal vibration detection method, device, equipment and medium, comprising: obtaining historical running data of a target rolling mill, the historical running data comprising vibration measurement data, rolling piece plate shape data, rolling piece production data and rolling process data corresponding in time sequence; constructing a training sample set and a test sample set according to the historical running data; training a preset prediction model according to the training sample set and the test sample set to obtain a target prediction model; obtaining real-time running data of a rolling mill to be detected, and inputting the real-time running data into the target prediction model to determine whether the rolling mill to be detected has abnormal vibration. The application can find the best speed reduction window before the abnormal vibration causes great damage to the rolling mill or the rolling piece, and thus the rolling mill can be controlled to reduce the speed in time, the occurrence probability of abnormal vibration is reduced, the rolling quality of the rolling piece is improved, and the service life of the rolling mill is prolonged to a certain extent.

The utility model relates to the field of steel rolling, discloses a roller cooling mechanism for steel rolling, and solves the problems that the existence of impurities can interfere with the full contact between a cooling medium and the surface of a roller, hinder heat transfer, reduce the cooling efficiency and further influence the performance of the roller and the rolling quality of the steel. A roller cooling mechanism for steel rolling comprises a base, a first supporting plate fixedly connected to the upper portion of the base and a roller arranged on the inner side of the first supporting plate, and a rotating mechanism is arranged, so that when rotating, the rotating mechanism drives a scraping plate to move transversely, and then scraping is conducted on the scraping plate. And the scraping plate is always kept to clean in front, and the water spraying head is always kept to spray cooling liquid behind, so that the cooling liquid can be better contacted with the roller for heat exchange, the cooling effect is improved, and the rolling quality of steel is improved.
