Embodiment Construction
[0044] Below, the structure and working principle of the present invention will be further described in conjunction with the accompanying drawings.
[0045] figure 2 It is a schematic structural view of the first embodiment of the device for controlling residual oil on the surface of the single-stand cold-rolled strip steel of the present invention. As shown in the figure, a first emulsion injection mechanism 3 is set at the inlet end of the cold-rolling mill 1 for In cooperation with the existing roll gap emulsion spraying mechanism 7, the emulsion is sprayed towards the upper and lower surfaces of the strip steel 6. The first emulsion spraying mechanism 3 has a first injection port 21 arranged above the strip steel 6 and a The lower second spray port 22, the first spray port 21 and the second spray port 22 spray the emulsion vertically toward the upper and lower surfaces of the steel strip 6, respectively.

The invention discloses a single-stand cold rolling mill rolled strip steel surface residual oil control device and method. The device comprises a first emulsion spraying mechanism provided with a first spraying opening and a second spraying opening, the first spraying opening and the second spraying opening are formed in an inlet of the rolling mill, the first spraying opening is formed above strip steel and used for spraying emulsion towards the upper surface of the strip steel, and the second spraying opening is formed below the strip steel and used for spraying emulsion towards the lower surface of the strip steel. By means of the single-stand cold rolling mill rolled strip steel surface residual oil control device and method, the surface residual oil of a single-stand rolled steel plate can be effectively controlled, no special requirement for on-site production and operation exists, and the use value is high.
Description
technical field [0001] The invention relates to the technical field of cold rolling, in particular to a device and method for controlling residual oil on the surface of a single-stand cold-rolled strip. Background technique [0002] At present, in the production of modern cold rolling mills, based on the consideration of rolling efficiency, yield and manufacturing cost, continuous rolling is generally used for production. However, the continuous rolling production process faces problems such as huge investment, fixed rolling passes, and poor production flexibility. Therefore, when producing some high-strength and thin-gauge cold-rolled steel products, they are usually produced with single-stand reversible rolling equipment. The main consideration is that the production process of this type of rolling mill is not limited by the number of stands and rolling passes. . [0003] Usually, in the production of cold rolling technology, a complex emulsion system is used to spray a ...
