Problems solved by technology
[0004] The above method has a certain effect on strip steel with a thickness greater than 0.18mm. However, when the thickness of the strip steel is less than 0.18mm, it is very difficult to coil and start the strip steel. At this time, the method of optimizing the coiling tension can no longer solve the strip steel wrinkle. Cramps and other problems, often need to repeatedly cut off the poorly coiled strip, which seriously affects the production efficiency

Abstract
The invention discloses ultrathin strip steel coiling equipment which comprises a coiling machine, a compression roller device and a driving device, wherein an L-shaped mechanical arm is used as the compression roller device, and one end of the compression roller device is fixed above the rear side of the coiling machine and serves as the rotating center of the compression roller device; the driving device is arranged on the rear side of the coiling machine, is connected with the rotating center of the compression roller device and drives the compression roller device to rotate around the rotating center. The invention also provides an ultrathin strip steel coiling method which comprises the following steps of: collecting equipment parameters of a winding drum and a compression roller; collecting characteristic parameters of strip steel; giving various working condition coefficients; calculating the lifting position of the compression roller; defining parameters in a coiling process, and giving the maximum coiling radius; calculating the coiling radius; judging the position of the compression roller; judging whether the coiling radius is less than or equal to the difference obtained by subtracting the thickness of the strip steel from the maximum coiling radius. The invention provides a coiling method and equipment suitable for ultrathin strip steel, and the coiling quality of the strip steel can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of cold rolling, and more specifically, relates to a coiling device and method for an ultra-thin steel strip. Background technique [0002] The product specifications produced by the secondary cold rolling unit are relatively thin, the thinnest product thickness of the smooth mode product can reach 0.15mm, and the thinnest product of the secondary cold rolling mode can reach 0.05mm. For ultra-thin strip steel, in the actual production process, in addition to defects such as difficult rolling, poor shape, substandard performance, and unqualified surface quality, coiling defects are also another problem in the production process of ultra-thin strip steel. Difficulties belong to the focus of on-site research. In the production process of extremely thin strip steel, typical coiling defects include strip wrinkling and cramping. Take the coiling cramp defect that usually occurs in the inner core of the steel coi...
