Abstract

The invention relates to a multiple-transmission device for a rolling mill and belongs to a multiple-transmission device for a rolling mill in metallurgy industry. The multiple-transmission device is used for solving the technical problems of high possibility of slipping, low quality passing percent of products and small rolling range of a working roll in an existing four-roll or multi-roll rolling mill. In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the multiple-transmission device for the rolling mill comprises two rolling transmission devices, wherein one rolling transmission device is a support roll transmission device; the support roll transmission device is connected with a support roll and used for realizing large-torque rolling; the other rolling transmission device is a working roll transmission device; and the working roll transmission device is connected with the working roll and used for realizing high-speed small-torque milling. The multiple-transmission device has the advantages of multiple transmission devices, good product surface quality of rolled pieces, independent transmission and simultaneous transmission.

Description

technical field [0001] The invention relates to a multiple transmission device for a rolling mill, which belongs to a multiple transmission device for a rolling mill in the metallurgical industry. Background technique [0002] At present, there are two commonly used transmission methods for four-roll or multi-roll mills. One transmission mode is: the support roller is connected with the transmission device. The backup rolls of this transmission mode are power rolls, and the work rolls are passive rolls. The rolling range of the rolling mill in this transmission mode is large. When the reduction is large and the rolling force is large, the working condition is good and the quality of the rolled piece is good; When the reduction, rolling force and rolling torque are small to a certain value, the work roll often slips when the back-up roll is driven, causing scratches on the surface of the rolled piece and resulting in unqualified product quality. [0003] Another transmissio...
