Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rolling steel technology, especially a rolling mill double guide that can be quickly replaced. BACKGROUND

[0002] The short stress rolling mill is widely used in the hot rolling section production line of the rolling mill as the rough and medium rolling and pre-precision rolling mill unit. The short stress rolling mill unit has the advantages of compact structure, high rigidity and large rolling force, so that the rolling can be accurately controlled by the hole type size to realize the preliminary processing of the shape and size of the steel.

[0003] During the rolling process of the short stress rolling mill, due to the factors such as roll wear, thermal expansion and rolling force fluctuation, it is difficult to maintain good rolling size and stable surface quality for a long time, so it is necessary to replace the rolling groove and the corresponding imported guide or replace the rolling mill, which not only increases the downtime, but also increases the production cost.

[0004] In the operation process of replacing the rolling mill or the guide, the crane needs to be used for lifting operation. When facing the task of replacing multiple rolling mills at the same time, in order to compress the downtime to the maximum extent and improve the production efficiency, multiple workers are often organized to work synchronously on the spot, forming a tense and complex cooperation situation. However, in this multi-line parallel operation mode, all the personnel involved in the lifting must wait for the lifting work of all the rolling mills to be completely finished before they can enter the working area uniformly to adjust and confirm the subsequent rolling center line. If it is in a hurry, the personnel may approach the rolling mill for adjustment without ensuring that all the lifting equipment has been safely removed and the working area has been thoroughly cleaned, which may increase the risk of being hit by unstable objects or tripping over ground objects when the crane is moving.
