Abstract
The present invention discloses a tension control method and system for a looper for an annealing production line. A tension control method for the looper comprises the steps of obtaining a current operating speed of the looper; and determining a tension set value in linear matching with the current operating speed, and sending the determined tension set value to a tension controller such that the tension controller controls the tension between the looper and strip steel based on the tension set value in linear matching with the current operating speed. According to the present invention, the technical problem of strip breakage due to mismatching of the tension between the looper and the strip steel with the field operating state of the strip steel in the prior art is solved, and therefore, long-time trouble-free operation of the annealing production line is ensured.
Description
technical field [0001] The invention relates to the technical field of annealing, in particular to a looper tension control method and control system in an annealing production line. Background technique [0002] When the 1420 continuous vertical annealing production line is in normal production, the strip thickness is generally between 0.15mm-0.25mm. In the production process, the speed of the looper of the 1420 continuous vertical annealing production line is not constant, but is constantly changing according to the specifications and steel types of the strip to be produced, but the tension of the looper controls the thin-gauge strip When the looper is running at a low speed, setting too much tension between the looper and the strip will cause the strip to wrinkle and break; Insufficient frictional force, severe slippage between the strip steel and the rollers will cause the surface of the strip steel to be scratched or even broken. Therefore, in the prior art, the tensio...
