Tension control system and method for planetary gear structure tension roller type evener

Abstract

The invention discloses a tension control system of an epicyclic gear tension roll leveler, which comprises an inlet pull tension gage and an inlet tension feedback device, an outlet pull tension gage which is provided in the outlet of the leveler for measuring the strip tension in the outlet, an outlet tension feedback device for feedback the strip tension in the outlet which measuring by the outlet pull tension gage, a tension control device for receive the strip tension in the outlet which is feedback from the outlet tension feedback device. The roll-force, the elongation and the speed of the leveler can be definite by the association of strip tension in the inlet and outlet. The three key parameters comprises the roll-force, the elongation and the speed of epicyclic gear tension roll leveler, the coordinate cooperated controlled can be constructed among the three key parameters. According to the addition of tension in outlet with the outlet pull tension gage by the technical scheme of the invention, meanwhile the stable elongation, roll-force and tension control can be realized, and the order of stable strip steel property and shape can be achieved.

Description

Technical field [0001] The invention relates to the technical field of the control of a tension roller leveler, and more specifically, to a tension control system and method for a tension roller leveler with a planetary gear structure. Background technique [0002] The original leveling machine of the continuous annealing line belongs to a unique planetary gear structure, and there is only a set of tension measuring device at the entrance, which is installed at the entrance of the leveling machine. Therefore, it has instability in rolling force and tension control accuracy. Especially the tension at the exit of the leveler is out of control. [0003] reference figure 1 , figure 1 It is a structural diagram of a leveling machine used in the prior art. Such as figure 1 As shown, the leveling machine 100 includes: [0004] The motor 102 of the leveler adjusts the speed of the leveler; [0005] The speed calculation and adjustment device 104 calculates the speed of the leveler according...

Problems solved by technology

Since only the entrance tension meter 118 detects the entrance tension, the stability of the exit tension cannot be controlled, and only the entrance tension of the tempering machine can be adjusted

If all external factors are in a stable state, elongation, inlet and outlet tension, and rolling force may have a short-term balance, but it is also an unstable system that cannot withstand external interference (such as changes in the internal material of the strip, often Causes unstable rolling force of the temper mill or unstable outlet tension, or even loss of tension, resulting in edge waves, middle waves and other plate shape defects)

[0019] Based on the above analysis, the shortcomings of the original technology are: (1) lack of control means for the exit tension, the strip is prone to slack, which affects the quality of the plate shape, resulting in defects such as edge waves or rolling wrinkles at the exit; (2) the rolling force , Tension parameters can not be well matched, often appear the phenomenon of neglecting the other
