Description

(54) Rolgang

The invention relates to equipment for metal forming and can be used in rolling ingots or billets in reversing rolling mills.

. Rollers for transporting rolls in the line of a rolling mill / including a frame with drive rollers (1) are known.

To increase the productivity of reversing rolling mills, it is widely used; with multiple or co-rolling of ingots or preparations, it consists of two or more ingots or billets being rolled to the given dimensions, which increases the productivity of the mill by reducing the total time of pauses in the rolling cycle in relation to the millioin rolling time 2.

The disadvantage of multi-facet rolling vehicles is the limitation of the performance of the reversing rolling mill with an increase in the number of simultaneously rolled ingots due to the insufficient length of the roll bars from the front side of the rolling mill stand. .

This problem can be solved, for example, by temporary removal of one

or several rolls from the roller conveyor: the front stand and the release of the roller table for rolling the remaining ingots, and after rolling the latter by returning the removed rolls and rolling them.

The roller conveyor is different in that; that it is equipped with two parallelsMMHFjtMH meh: a1niems with a common drive, installed on both sides

5 frames of the roller table and interconnected horizontal crossbars, which are placed between the rollers of the roller table.

This embodiment provides for the formation of reserve zones for placing the rental on the roller table without increasing the production area occupied by it, for example, while simultaneously rolling several rolls.
