The C-shaped frame rotary type vertical rolling mill has earlier appearance, and the main principle is that a rolling mill body rotates on a C-shaped frame for 90 degrees to realize the switching between a horizontal state and a vertical state. The rolling mill train is characterized in that a set of main motor is adopted for driving, and the main motor is distributed and output to the mill rolls of a flat rolling mill or a vertical rolling mill through a gear box, a clutch and other devices, and the problems of inconvenient installation and maintenance are caused by complex transmission structure and high equipment processing and installation requirement precision.

Because the flat vertical rolling mill shares a set of fixed frame, the flat rolling mill is arranged below the vertical rolling speed reducer platform, and can not be directly hoisted by a crown block to move in and out of the station, and because the traversing stroke is large, a special traversing device is required to be equipped to move the flat rolling mill to a proper position for roll changing of the flat rolling mill.
However, the existing fixed frame type horizontal vertical rolling mill technology does not realize that a horizontal rolling mill and a vertical rolling mill are replaced by a set of roll replacing device, and a special horizontal traversing mechanism is required to be arranged for roll replacement of the horizontal rolling mill. The horizontal traversing device has a complex structure, the transmission of the horizontal rolling mill and the transmission of the vertical rolling mill have different structural dimensions, and key components such as a rolling mill moving base, a spindle bracket, a universal spindle, a spindle hydraulic cylinder and the like cannot be exchanged and used in a horizontal vertical rolling system, so that spare parts are inconvenient to manage, overhaul and maintain.
In the existing patent technology, a vertical rolling roll changing trolley and a transverse moving device are adopted for a vertical rolling mill body and a flat rolling mill body. In patent CN110090863a, the "horizontal rolling mill system is mounted on the base of the gear box", and the gear box, universal joint shaft and rolling mill are integrally moved during hole-changing of the horizontal rolling mill ", and its technical method is to adopt two-section universal joint shaft to increase the traversing stroke and realize the moving out of the horizontal rolling mill. In the CN212190606U, a roll changing trolley is provided for roll changing of the vertical rolling mill, "the vertical rolling mill is transported to the vertical rolling mill stand for installation and use by the roll changing trolley", the horizontal rolling mill is moved and changed by the horizontal rolling mill through a first transmission device to provide power for the horizontal rolling mill, and a horizontal traversing cylinder in a first hydraulic cylinder is installed on the side of the horizontal rolling mill stand opposite to the roll changing trolley to realize the removal and the change of the horizontal rolling mill, so that the roll changing of the horizontal rolling mill and the vertical rolling mill cannot be realized by a set of roll changing trolley.
