Problems solved by technology

[0002] The tension before the annealing furnace is very important to the tension in the furnace of the strip continuous processing unit. The fluctuation of the strip tension will cause the strip to wrinkle if it is light, and cause the belt to break in the furnace and stop the production of the unit if it is serious.

[0044] Please refer to figure 1 , this embodiment provides a buffered tension closed-loop control system 100, which is applied to the strip tension adjustment at the entrance of the galvanizing line, and includes a tension roller group 1, a tension stabilizer 2 and a furnace front tension roller 3 arranged in sequence.

[0045] In this embodiment, the tension stabilizer 2 includes a first turning roller 21, a buffer roller 22, a second turning roller 23 and a driving mechanism. The buffer roller 22 and the second diverting roller 23 enter the annealing furnace through the furnace front tension measuring roller 3. The cooperation of the first diverting roller 21, the buffer roller 22 and the second diverting roller 23 can adjust the tension of the strip steel and relieve the tension of the strip steel. Due to the influence of tension factors in the furnace, the driving mechanism is connected with the buffer roller 22, and the buffer roller 22 is driven to move along the forward...

[0054] This embodiment provides a buffered tension closed-loop control method, including:

[0055] At the exit of the looper at the entrance of the galvanizing unit, the tension roller group 1, the tension stabilizer 2 and the tension roller 3 in front of the furnace are arranged in sequence;

[0056] Tension roller group 1 close-loop adjusts the tension in front of the furnace;

[0057] The tension stabilizer 2 closes the loop to adjust the tension in front of the furnace.

[0058] In the step of "arranging and distributing the tension roller group 1, the tension stabilizer 2 and the tension measuring roller 3 in front of the furnace in sequence at the exit of the looper at the entrance of the galvanizing unit", the strip passes through the tension roller group 1, the tension stabilizer 2 and the furnace front in sequence. The tension measuring roller 3 enters the annealing furnace, and the tension measuring roller 3 in front of the furnace is provided with a tension sensor ...

Abstract

The invention relates to a tension closed loop control method with buffer and system, which belong to the technical field of metallurgical automation. The outlet of a galvanizing unit inlet loop is sequentially provided with a tension roll group, a tension stabilizer and a stokehole tension measurement roll. The tension value of a strip steel is detected in real time through a stokehole tension sensor, together with the tension roll group and the tension stabilizer, a two-closed loop tension adjustment control system is formed, the damping characteristics of the tension stabilizer are used toabsorb and buffer instantaneous disturbance of stokehole tension, the stable closed loop adjustment characteristics of the tension roll group are used to together stabilize and adjust strip steel tension fluctuation before an annealing furnace, the stokehole tension control precision and the stability are thus improved, and influences of impacts in dynamic processes of tension fluctuation in the case of charging and discharging of the inlet loop and other factors can be solved.

Description

technical field [0001] The invention relates to the technical field of metallurgical automation, in particular to a buffered tension closed-loop control method and system. Background technique [0002] The tension before the annealing furnace is very important to the tension in the furnace of the strip continuous processing unit. The fluctuation of the strip tension may cause strip wrinkles in the slightest, and cause strip breakage in the furnace and shutdown of the unit in severe cases. On the strip steel continuous processing unit that does not require high tension control accuracy, the general tension control can meet the requirements, but for the strip steel continuous processing unit with high requirements, the requirements for product shape and surface quality are very high, so the tension in the furnace is required Controls are more precise and stable. Contents of the invention [0003] The purpose of the present invention is to address the above problems, providi...
