Embodiment 1

[0031] Embodiment 1: see Figure 1-Figure 4 , a method for effectively monitoring the running effect of pickling anti-wrinkle rolls, said method comprising the following steps:

[0032] 1) The uncoiler is running,

[0033] 2) The anti-wrinkle roller is pressed down,

[0034] 3) Pressure detection, WS side position detection, DS side position detection input,

[0035] 4) Pressure detection input, the detection pressure value is <80Kg, the value of the position closed-loop encoder on the DS side = the set value of the pressure, and the inlet is operating normally.

[0036] 5) The input detection pressure of pressure detection is less than 80Kg, the calculation deviation of the position deviation between the DS side and the WS side is less than 5mm, and the inlet is in normal operation;

[0037] 6) Pressure detection input detection pressure < 80Kg, position deviation calculation deviation between DS side and WS side [5mm, 10mm), the screen pops up an alarm prompting that the ...

Embodiment 2

[0046] Example 2: see 2- Figure 4 , a device for effectively monitoring the operation of the pickling anti-wrinkle roll, the device includes an anti-wrinkle roll 1, a support roll 2, a support roll 3, a connecting bolt 4, a bearing seat 5, an encoder 6, an anti-wrinkle roll oil cylinder 7, a connecting Pin 8, support frame 9, swing frame 10, swing shaft 11, pressure roller 12, pressure roller swing bracket 13, pressure roller cylinder 14 and steel coil 15, and the pressure roller 12 is connected to the pressure roller cylinder 14 through the pressure roller swing bracket 13 The anti-wrinkle roller oil cylinder 7 is arranged on the support frame 9, the swing shaft 11 is connected to the swing frame 10, and the support roller 3 and the support roller 2 are fixed on the bearing housing 5 by connecting bolts.

[0047] Work process: before the uncoiler runs, the pressure roller 12 is lifted by the pressure roller cylinder 14 and the pressure roller swing bracket 13, then the uncoi...

Abstract

The invention relates to a method for effectively monitoring the running effect of an acid pickling anti-wrinkle roller. The method comprises the following steps that (1) an uncoiler runs; (2) the anti-wrinkle roller is pressed down; (3) pressure detection, WS side position detection, DS side position detection are put in; (4) pressure detection is put in, the detection pressure value is smaller than 80 Kg, the value of DS side position closed-loop encoder is equal to the press-down set value, and an inlet runs normally; (5) pressure detection is put in, the detection pressure is smaller than80 Kg, the calculation deviation of the DS side and WS side position deviation is smaller than 5 mm, and the inlet runs normally; (6) pressure detection is put in, the detection pressure is smaller than 80 Kg, the calculation deviation of the DS side and WS side position deviation is [5 mm, 10mm), alarm prompt is popped out of the image, and the inlet still runs normally; (7) pressure detection isput in, the detection pressure is smaller than 80 Kg, the calculation deviation of the DS side and WS side position deviation is larger than or equal to 10 mm, and the inlet segment is quickly stopped after 1 s; and (8) pressure detection is put in, the detection pressure is smaller than 80 Kg, and the inlet segment is quickly stopped after 1 s.

Description

technical field [0001] The invention relates to a method, in particular to a method for effectively monitoring the running effect of a pickling anti-wrinkle roller, and belongs to the technical field of electromechanical control. Background technique [0002] Among the various factors that determine the pickling effect of cold-rolled strip steel in today's world, the use of anti-wrinkle rolls plays a considerable role. Therefore, all domestic cold-rolling has adopted the device of anti-wrinkle rolls, and its purpose is to ensure good Excellent scale breaking effect, improving the shape of the strip and preventing the strip from buckling. Since the hot-rolled incoming material itself is not very straight, there are always irregular extensions such as sickle bends and waves. The contact force of the roll surface is inconsistent, so there will be inconsistent wear at both ends and the middle part, resulting in a special-shaped roll surface, which will cause the contact surface...
