Abstract

The invention discloses a temporary substitute device for rolls of a continuous rolling mill unit. The temporary substitute device comprises a lower roll table base, an upper guide and guard frame and a roll assembly. The lower roll table base is connected with the lower portion of the upper guide and guard frame, and the upper portion of the upper guide and guard frame is connected with the roll assembly. The lower roll table base comprises a transmission side base body and an operation side base body, and the transmission side base body and the operation side base body are connected through a steel plate. The distance between the inlet plane of the operation side base body and the outlet plane of the operation side base body is matched with the width of an operation side bearing pedestal of a rolling unit bottom working roll, and the distance between the inlet plane of the transmission side base body and the outlet plane of the transmission side base body is matched with the width of a transmission side bearing pedestal of the rolling unit bottom working roll. The temporary substitute device can improve the efficiency of a production line, guarantee the surface quality of rolled products and lower the consumption of the rolls, and is reasonable in structural design and convenient to install and use.

Description

technical field [0001] The invention relates to a roll replacement device, in particular to a temporary roll replacement device when a single frame in a continuous rolling mill breaks down. Background technique [0002] In the continuous rolling production line, the continuous rolling unit is the core equipment of the whole production line and the key to the stable operation of the whole production line. Its complex equipment, high degree of automation and high equipment precision determine the production efficiency of the whole production line. The continuous rolling unit is composed of multiple similar rolling mills that are combined, allocated, and coordinated to complete the entire rolling process. When one of the stands fails, the entire rolling unit will not be able to operate, especially as the drive system of the rolling mill - the main drive system. This results in longer downtimes and seriously affects the efficiency of the rolling line. Generally, a single rack i...
