Rolling mill and rolling system

Abstract

The invention provides a rolling mill and a rolling system. The rolling mill comprises a base, a rolling roller set, a first driving device and a second driving device. The rolling roller set is detachably arranged on the base, the rolling roller set is provided with a rolling mill center line; the rolling roller set can be overturned under the action of an external overturning mechanism, so thatthe rolling mill center line is capable of extending in the longitudinal direction or transverse direction; the first driving device is provided with first connecting shaft groups, and the first connecting shaft groups are arranged above the base at intervals; the first connecting shaft groups can be in transmission connection with the rolling roller set when the rolling mill center line extends in the longitudinal direction; the second driving device is provided with second connecting shaft groups; the second connecting shaft groups are arranged on one side of the base, and the second connecting shaft groups are located below the base; and the second connecting shaft groups can be in transmission connection with the rolling roller set when the rolling mill center line extends in the transverse direction. According to the embodiment manner, the rolling mill and the rolling system which can ensure connection in place and can improve the connecting stability are provided.

Description

technical field [0001] The present application relates to the technical field of steel rolling, in particular to a rolling mill and a rolling system. Background technique [0002] In the steel rolling process, it is necessary to use a horizontal or vertical rolling mill for a certain pass. Therefore, in the prior art, the rolling mill of this pass is designed as a horizontal and vertical convertible mode. [0003] Such as figure 1 As shown, the horizontal-vertical convertible rolling mill in the prior art generally includes a rotating movable frame 57, a rolling mill body 59, a third speed reducer 61, a third connecting shaft 63, a third motor 65, a clutch 67, a bevel gear box 69, Overturn hydraulic cylinder and traverse hydraulic cylinder 71. Wherein, the rolling mill body 59 , the third speed reducer 61 , the third connecting shaft 63 , the turning hydraulic cylinder and the traverse hydraulic cylinder 71 are fixed on the rotating movable frame 57 . When the mill body ...

AI Technical Summary

Problems solved by technology

[0004] Since the rolling mill body 59 is fixed on the movable frame, and the movable frame is easily deformed during long-term use, when the movable frame deforms, it is easy to cause the extension direction of the center line of the rolling mill body 59 to deviate from the original horizontally or vertically. As a result, when the movable frame drives the rolling mill body 59 to switch between the horizontal state and the vertical state, the connection between the rolling mill body 59 and the clutch 67 is not in place, thus affecting the stability of production
