Abstract

PURPOSE:To improve the accuracy in controlling the thickness of a rolled material by virtue of measurement in desired positions by obtaining the outputs of a pulse generator which generates the pulses corresponding to the number of revolutions of a rolling roll and the timing for measuring the thickness from the rolling force of the rolled material. CONSTITUTION:A rolled material 2 advances by DELTAl at every one pulse of a pulse generator 7. The generator 7 generates n0 pulses since the preceding end of the material 2 is gnawed in a rolling mill 1 until the same arrives at the part right under a width gage 6. Similarly, the pulse generator 7 generates n1 pulses since the preceding end is gnawed in the mill 1 until the same arrives at the l1 right under the thickness gage 5. In other words, the material 2 is right under the gage 5 at the timing of the pulse given by the equation 1 after the gnawing in the mill 1. In the case of controlling the width, it is possible to control a vertical roll in conformity with the timing at the horizontal roll by placing the vertical roll in the position of the thickness gage.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides 1ii) a method for uniformly controlling the rolling thickness of the rolled material in 41. ＃It is also possible to use a synchronizing device that provides a constant timing. @Conventional ζ
There was one shown in the M1 cabinet as an O-class device. In the figure, (υ is the rolling machine, (2J, (3) is the material to be rolled, (4; is the pressure constant device, and (5J is the abrasive material (210 plates The thickness needle αa keeps the thickness constant, and the rolling # (27 pressure island force 7 thickness 'S, the pressure constant device cage 4) and the thickness 1 measurement curve are individually timed to make it constant a. This is an information processing S device that appropriately adjusts the 0@ constant value to KJ61m.

Next, I will explain the operation. The plate thickness of the plate rolled by the rolling mill 113K is determined by calculating the following equation using the rolling force F, which is made constant by the positive arc force measuring device 141K, by the taste processing device (41).

This invention was made in view of these points,
It is an object of the present invention to provide a synchronizing device that can easily maintain the same thickness of a rolled material at the same location.

An embodiment of the present invention shown in FIG. 2 will be described below. In the figure, the same reference numerals as those in the kite 1 figure indicate the same or corresponding parts, so the explanation thereof will be omitted.

(6) is a plate width meter that optically keeps the width of the rolled material 123 constant; (7) is a pulse generator (hereinafter referred to as PLG) that keeps the rotation of the rolling roll of the rolling stock 117 constant; It is attached to the above-mentioned rolling roll. go is the distance between the plate width gauge (63) and the rolling mill (1), and #0 is the distance between the koji press machine 113 and the thickness gauge (57).

Next, the operation will be explained. PLG (7) is the rotation angle Δ# of the rolling roll (one pulse is generated every radian, and if the rolling roll radius of the rolling mill 11 is Fem, the applied pressure K is calculated for every pulse of PLO (7). Material 12+ is ΔI Δ#=(1+d)r・Δω・・・・・・・・・・・・
・・・・・・・・・・・・・・・・・・(It is known that C is advanced by 21. Here, Cα is called the advance rate, and it changes depending on the state of reduction in normal rolling, but it has almost no effect on the rolling speed. Under the above assumption, the tip of the pressurized material (2) is bitten by the rolling mill (11) and the KPLG is (73 is no. Assuming that a pulse is generated, go = Δ1lXn o −(1+d) r ”ΔQI
Similarly to Xnl"""137, piG(7) is inserted into the rolling mill (1) and reaches just below the thickness gauge 153.

...... The thickness needle of the rolled material 123 is located directly below the needle (57).

Normally, the timing when thickness gauge 157 can be read is thickness gauge 1
57, but this method allows timing to be given completely independently.

Note that the rolled material + 21 (if the tip of the D shape is straight as shown in Fig.
The tip shape of J is the 3rd t! In many cases, the timing of the rising 6t'' of the thickness needle does not match at all.However, according to the present invention, it is possible to provide timing in synchronization even in such cases. This will be explained below using Fig. 114. In Fig. 114, a typical example in which the shape of the rolled material (2) is lbJ will be explained.

In Fig. 4, the rolling mill (lJ 1 width gauge (61), the central thickness gauge 15J, and the end thickness needle (octopus) were arranged as shown in the figure.The horizontal axis represents the output of each 7 gauges. (7) Assume that the waveform shown in the figure is obtained when the number of pulses C is increased by σ.If the time delay of each instrument is ignored, the rise of the rolling force meter output (101) and the plate width meter output CIOω are The difference in the rise 9 is no pulse.However, the rise of the output of the thickness needle (51) largely depends on the tip shape of the material to be rolled (2), and in the case shown, the center thickness gauge L5J

7 am does not have a very large value 0 In this way, the OVA difference changes depending on the tip shape of the material to be rolled (2) and the position in the width direction of the thickness needle. Now, if we take the timing of the rolling force and plate width meter when the fore-side compression force and width exceed 9011, the warpage part can be determined in the rolled material (2) (#@4 Figure 71) ) of this invention, the method Cn+ = kX no

Timing C1 It becomes possible to provide the timing when the above-determined portion comes to the true position of each thickness gauge.

According to this method, these timings are the same as the rolling material (2)
Regardless of the shape.

In addition, although the above-mentioned embodiment C has been described as an example in which the measurement timing of the thickness gauge 163 is provided, it can also be applied to cases in which all kinds of constant timings are provided, such as the side leg timing of a thermometer, the planar shape measuring meter, etc. be.

In addition to measurement, when performing board width control etc., place a vertical roll (edger roll) at the position of the thickness gauge, and adjust the timing when controlling the edger roll to match the timing of the horizontal roll C. C can also be applied to giving.

As described above, according to the present invention, the timing signal is obtained from the output of the pulse generator that generates pulses corresponding to the rotation speed of the rolling rolls of the rolling mill and the rolling force of the rolled material. An accurate timing signal can be obtained regardless of the shape of the material to be rolled, the -j constant of the thickness at a desired position of the material to be rolled can be determined, and the accuracy of thickness control can be improved.
