Problems solved by technology

[0003] The technical problem to be solved by the present invention is to realize a tension control method, which fully considers the unfavorable factors for tension control caused by the configuration of the powerful straightening machine to make the production line lengthen, and realizes the automatic belt threading and operation of the unit. The tension is stable and controllable, which avoids the problems of large strip vibration and easy scratches caused by the lengthening of the production line, and ensures the high-speed and stable operation of the hot-rolled skin pass unit

Abstract

The invention discloses a tension control method for a leveling and winding unit, and the tension control method has two working modes: rewinding and leveling. According to the tension control method,stable and controllable tension of the unit in the tape threading and operating process is achieved, and the problems that strip steel shakes severely and is liable to scratch and the like are solved; and powerful support is provided for achieving automatic tape threading of the unit and improving the automation degree as well as the product quality and the finished product rate of hot-rolled strip steel.

Description

technical field [0001] The invention relates to the technical field of metallurgical automation control, in particular to the tension control technology of a hot-rolled skin pass and decoiling unit. Background technique [0002] The hot-rolled tempering and decoiling unit is an important production process to improve the strip shape quality and mechanical properties. Unit tension control tightens the loose strip steel to ensure the smooth transmission of the production line strip steel. Its control method and control accuracy directly affect the production efficiency, product quality and yield of the production line. It is one of the key control technologies for this type of production line . With the continuous development of hot-rolling technology, the strength level of high-strength steel is gradually increasing and the market's requirements for the quality of hot-rolled strips are also getting higher and higher. The capacity is obviously insufficient, and there is a la...
