The support unit consists of a first bottom plate 1 and a second bottom plate 22, which are fixedly connected to form the foundation of the rolling mill. A frame 2 is fixed above the first bottom plate 1, and a crossbar 7 is fixed inside the frame 2. Then the execution unit is installed: the execution unit, i.e., the roller 31, is installed below the crossbar 7. The roller 31 consists of two sets of parallel and symmetrical rollers, with end covers 35 at both ends. The end covers 35 are connected to the upper bearing seat 34 and the lower bearing seat 30 to support and protect the roller 31.
