Problems solved by technology

For the ultra-thin steel strip below 0.05mm, due to problems such as poor plate shape and large inclusion size during the production process, if the tension control is unreasonable, it is easy to cause problems such as strip draw and strip breakage during the rolling process, resulting in strip failure. The finished product rate is reduced, which causes a large economic loss to the production

Embodiment Construction

[0037] In order to better understand the purpose, structure and function of the present invention, a method for controlling the coiling tension of an ultra-thin steel strip according to the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 , figure 2 , image 3 , Figure 5 Shown is an embodiment of the invention, figure 1 It is a block diagram of the structure of the rolling mill in the embodiment of the present invention, from figure 1 It can be seen that the rolling unit includes: uncoiler, entrance thickness gauge, rolling mill roll, exit thickness gauge, tension gauge roll, and coiler. The steel strip passes through the entrance thickness gauge, rolling mill roll, exit thickness gauge and tension gauge roll from the uncoiler to the coiler, and the coiler uses a belt coiler to complete the coiling of the steel strip. For the specific structure of each of the above devices, reference may...

Abstract

The invention relates to an ultra-thin steel strip coiling tension control method. The technical problem that tension is difficult to control in the ultra-thin steel strip rolling process is solved. The tension control method comprises the following steps that firstly, static tension is established for an uncoiler and a coiler before a steel rolling unit operates; secondly, after the steel rolling unit operates, a tension value of a steel belt is detected, and a detection result is used for adjusting the output torque of a motor of the coiler; and thirdly, in the ultra-thin steel strip rolling process, torque compensation is conducted on the coiler, the tension of the steel strip is made to be constant, and the load torque MZ of the coiler comprises the steel strip tension torque MF, the rotational inertia torque MD, the steel strip bending torque Mw and the transmission system friction torque Mf. According to the technical scheme provided by the invention, strip drawing and strip breakage are avoided in the ultra-thin steel strip coiling process, so that a steel coil can be tightly and neatly coiled, the performance requirement of a product is met, and the production efficiency is also improved.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a method for controlling the coiling tension of an ultra-thin steel strip. Background technique [0002] Ultra-thin stainless steel strips have entered aerospace, medical electronics, communication semiconductors, auto parts and other fields, and have very high added value. For the ultra-thin steel strip below 0.05mm, due to problems such as poor plate shape and large inclusion size during the production process, if the tension control is unreasonable, it is easy to cause problems such as strip draw and strip breakage during the rolling process, resulting in strip failure. The finished product rate is reduced, thereby causing greater economic losses to production. Contents of the invention [0003] In order to solve all or part of the above-mentioned problems, the object of the present invention is to provide a method for controlling the coiling tension of an...
