Problems solved by technology

However, the design did not take into account the thick and thin layers of tin-plated products, and the tin-plated products have high requirements for coiling. Collapsing and deviation are prone to occur during coiling, which affects the appearance and quality of finished coils.

Embodiment 1

[0032] Coiler threading tension control method to prevent collapse phenomenon, control the coiler threading tension according to the thickness of the strip, when the thickness is below 0.206mm, use the threading tension of 1.38 times the set tension, and the thickness is 0.206mm When the thickness is between 0.358mm and 0.358mm, the threading tension is 1.4 times the set tension; when the thickness is above 0.3580mm, the threading tension is 1.5 times the set tension.

[0033] The system automatically judges the thickness grade of strip steel based on the incoming thickness data of the strip steel, and transmits the corresponding set value of threading tension to the tension parameter variable. The threading tension of the specification strip. In this way, by controlling the threading tension of the coiler, the collapse of the coil caused by improper threading tension can be effectively avoided.

Abstract

The invention relates to an anti-buckling coiling machine strip steel threading tension control method. Currently, in the aspect of coiling tension control of a coiling machine of an electrolytic tinning machine set, a single and fixed strip steel threading tension control mode is adopted, obvious thickness grades of tinned products are not considered, buckling and displacement are prone to happen in the coiling process, and the appearance and quality of a finished coil are affected. In the method, strip steel threading tension of a coiling machine is controlled in a graded mode according to the thickness grades of the strip steel, strip steel threading tension 1.38 times larger than set tension is adopted when the thicknesses are smaller than 0.206 mm, strip steel threading tension 1.4 times larger than the set tension is adopted when the thicknesses range from 0.206 mm to 0.358 mm, and strip steel threading tension 1.5 times larger than the set tension is adopted when the thicknesses are larger than 0.3580 mm. By means of the method, buckling caused by incorrect strip steel threading tension can be effectively avoided, and stable and effective operation of a machine set are guaranteed.

Description

[0001] Technical field: [0002] The invention relates to a method for controlling the threading tension of a thin strip steel in a tinning machine, in particular to a method for controlling the threading tension of a coiler to prevent collapse. [0003] Background technique: [0004] Coiler is one of the main equipment on the strip production line, tension coiler is widely used in the production of strip steel and non-ferrous strip. In addition to being used in reversing rolling mills and continuous rolling mills, tension coilers are also widely used in production lines such as pickling units, skin pass units, finishing units and coating units. The coiler is basically composed of a reel and a reducer body, and some are equipped with floating bases, pressure rollers, coiling aids and auxiliary supports as needed. [0005] The tension of the coiler should be selected carefully, especially for thinner tinned products. If the tension is too large or too small, it will cause st...
