A method for setting process lubrication system for single-stand reversing rolling mill in cold rolling

Abstract

The invention relates to a technological lubrication system setting method for a cold rolling single stand reversing mill. Through adjusting the flow of an emulsified liquid during a rolling process,the rolling pressure in the whole rolling process can be uniform, the whole rolling force deviation is smaller, the thickness fluctuation during the whole rolling process is reduced, and the problemsthat during an actual production process of an existing cold rolling single stand, the relatively fixed emulsified liquid flow is adopted, so that a big difference of the rolling force of each pass iscaused, and the thickness difference control fluctuation during the production process is larger are solved.

Description

technical field [0001] The invention relates to the technical field of cold rolling, in particular to a method for setting a process lubrication system for a single-stand reversing rolling mill of cold rolling. Background technique [0002] In the production of modern cold rolling mills, based on the consideration of production efficiency and investment cost, two manufacturing methods are generally used for production: continuous rolling method and single stand method. The continuous rolling production process has high efficiency but huge investment and poor rolling flexibility. Relatively, the single-stand reversible rolling method is used for production, which has low production efficiency, but the initial investment is small and the production process is not limited by the number of stands. For the production of special steel grades or high value-added products. [0003] Usually, in cold rolling production, a certain amount of emulsion is sprayed to the roll gap and the ...

Problems solved by technology

[0009] The purpose of the present invention is to provide a method for setting a process lubrication system for a cold-rolled single-stand reversing mill. The method of the present invention makes the rolling pressure of the entire rolling process uniform, and the overall rolling force deviation becomes small. Thickness fluctuations in the entire rolling process are reduced to solve the problem that the existing cold-rolled single stand often uses a relatively fixed emulsion flow rate in the actual production process, resulting in large differences in the rolling force of each pass, resulting in thickness differences in the production process Problems with large fluctuations in control
