The two pieces of “Archive” are used to install the roll chock and the roll adjustment device. It needs enough strength and rigidity to withstand the rolling force. There are two main types of racks: closed and open. The closed frame is an integral frame, with high strength and rigidity, and is mainly used in large rolling mills and strip mills. The open frame is composed of two parts: the frame body and the upper cover, which is convenient for roll change. It is mainly used for horizontal profile rolling mills.
In addition, there are no mills.
