Embodiment Construction

[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The present invention proposes a process lubrication system setting method suitable for cold-rolled single-stand reversible rolling mills. The number of stand rolls in the cold-rolled single-stand reversible rolling mill can be 4 rolls, 6 rolls, 12 rolls, 18 rolls or 20 rolls. roll. The process lubrication of the cold-rolled single-stand reversing rolling mill of the present invention adopts such as figure 2 In the shown structure, the emulsion injection mechanism 7 is equipped at the roll gap of the single-stand reversing rolling mill in cold rolling. In other embodiments, emulsion injection beam devices 3 can also be added on both sides of the rolling mill. The emulsion is cold During rolling production, a small amount of rolling oil and a large amount of water are mixed through a stirring device; the concentration, tempera...

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 ...
