Description

technical field [0001] The invention relates to the technical field of steel rolling machinery, in particular to a water-cooled roller table with a guide ring. Background technique [0002] Roller tables are widely used in steel rolling production lines to convert rotary motion into linear motion for conveying intermediate blanks and rolled pieces. It is an important transportation equipment for realizing workshop automation. In the hot rolling production line, the roller table generally runs through the entire production line, connecting adjacent equipment and conveying intermediate billets and rolled pieces. The operation of the roller table directly affects the production of the rolling line. Therefore, the correct and reasonable design of the roller table is of great significance for reducing the cost of workshop equipment and increasing the output of the rolling mill. During hot rolling production, the weight of the intermediate billet and rolled piece is large, the i...

Problems solved by technology

However, the cooling water flowing inside the roller table is mostly turbulent flow, resulting in uneven cooling of the roller table, large and uneven temperature gradient inside and outside the roller table, and the roller table not only bears radial temperature stress, but also bears large axial temperature stress. , reducing the life of the roller table

At the same time, due to the uneven distribution of cooling water in the roller table, good dynamic balance performance cannot be guaranteed when the roller table is running at high speed, causing the roller table to shake

In order to improve the cooling effect, the cooling water flow is often increased, resulting in a waste of water resources
