Abstract

PURPOSE:To provide a size controller for continuous rolling mills which controls breadth sizes always constant despite change in the temp. of rolling mills by correcting the set tension values of the continuous rolling mills according to the change in the temp. of the rolling mills. CONSTITUTION:The temp. of a rolled material 3 is measured with a thermometer 12 and deformation resistance is operated with an operator 14 for deformation resistance. Said resistance is stored into a memory 15 for tracking of the deformation resistance. More specifically, plural deformation resistance values of the material 3 from the point where the thermometer 12 is installed up to the point right under the roll of the 1st stand roll 2 are stored in the memory 15. From the contents of the memory for said deformation resistance value and the set tension values between the stands, correction values for tension are operated. Said correction values are added 17 to the set tension values, which are then applied as command values of a tension controller 11. Now when the measured temp. drops lower than the reference temp., a change in the breadth sizes arises in the set tension values, but the tension is increased by adding the correction values for tension to the set tension values by an adder 17 for set tension, whereby the change in the breadth size is obviated.

Comparator (11
1)) A control calculator (llc) calculates the speed correction amount of the first stand (2) so that this deviation signal becomes zero, and outputs it to the speed command adder (8). As described above, the tension of the rolled material (3) could be kept constant.

従来の連続圧延機の張力制御装置は以上のように構成さ
れているので、張力を設定値に一定に保つことはできて
も、圧延材（１）の温度変化に起因する寸法変化が除去
できないという欠点があった。The tension control device of a conventional continuous rolling mill is configured as described above, so although it is possible to keep the tension constant at a set value, it is not possible to eliminate dimensional changes caused by temperature changes in the rolled material (1). There was a drawback.

この理由は、圧延材（１）を大形ロールで圧延すると、
張力により巾寸法が質化すると同時に圧延材温度変化に
起因する変形抵抗の変化によって巾寸法が変化するため
でああ。The reason for this is that when rolled material (1) is rolled with large rolls,
This is because the width becomes rougher due to tension and at the same time changes due to changes in deformation resistance caused by changes in temperature of the rolled material.

タンド間張力（圧縮力）により変化する。This will be explained below with reference to FIGS. 2 to 5, using a rolling mill composed of large rolls as an example. FIG. 2 shows a cross section of a rolled material in a continuous rolling mill, and (a) shows 1-1. The cross-sectional shape between the i-stands and the cross-sectional shape after the stand is shown. Figure 3 shows the cross-section of the mouth hole (2) and the rolled material (3) in the first stand. Width dimension BII
i. Since rolling roll (2) K is not comfortably restrained, it changes depending on the tension (compressive force) between the stands.

５図に圧延材温度と変形抵抗の関係を示すが圧延材温度
が高くなると変形抵抗が小さくなる。FIG. 4 shows the relationship between the tension (compressive force) between stands and the width variation ΔB. That is, when the tension is large, the width variation ΔB becomes large in the self-direction, and when the compression force is large, the width variation ΔB becomes large in the positive direction. When the deformation resistance of the flat rolled material (3) is small, the relationship between the medium dynamic ΔB and the tension (compressive force) becomes large. FIG. 5 shows the relationship between the temperature of the rolled material and the deformation resistance. As the temperature of the rolled material increases, the deformation resistance decreases.

延材（３）の巾寸法が変化する。Because of the above relationship, if the temperature of the rolled material changes while the tension value is kept constant, the deformation resistance will also change, and for example, if the temperature at that location drops F as in skin marks, etc.
The deformation resistance increases, and the width of the rolled material (3) changes from point A to point B shown in FIG.

It is intended to.

Since there is a distance from the installation location of 12) to the first stand roll depending on the control conditions of the installation location, the rolled material (
In order to track the transfer process in step 3), the deformation resistance Km calculated using the roll rotation detection device (13) is stored in the deformation resistance tracking memory (15). Therefore, the deformation resistance value KJI11 of the rolled material from the temperature needle (12) installation point to just below the first stand roll is stored in the memory (15).
Multiple items are stored. The memory content Km of the first stand roll direct, and the inter-stand tension setting value Ti, 1-IK
Accordingly, the tension correction value 7Ti, 1-1 is calculated using the following formula.

がある。The above-mentioned operation will be explained with reference to FIG. 7. The solid line shows the relationship between the tension car width variation at the reference temperature, and the dashed line shows the relationship between the tension car width variation at the measured temperature. Set tension Ti,
In the case of the reference temperature at i-1, there is a width variation value at one point on the solid line.

できる。When the measured temperature falls below the reference temperature, the tension setting value Ti,i
'-1, the width variation 7B moves to point B on the dashed-dotted line and a width dimension change occurs, but the set tension adder (17) converts the tension correction value 7Ti, 1-1 into the tension setting value Ti, i-s. By increasing the tension by adding to , it is possible to shift to the 0 point on the dashed line and cause a width dimension change to occur, thereby eliminating it.

A better embodiment in which the stand speed may be directly corrected is shown in FIGS. 8 and 9.

て演算器（１６０）を付加している。In FIG. 8, the roll speed is directly corrected according to the inter-stand tension correction value, and the set tension value is corrected according to the responsiveness of roll speed change - tension change. In the figure, (1
6a) is a calculator that derives the stand tension correction value from the deformation resistance, (16li is a constant that converts the stand tension correction value to roll speed, (16C) f′i stands tension correction value command, This is an arithmetic unit that matches the responsiveness of changes in roll speed and changes in tension.Since the roll speed changes with the output of constant a (161)), the tension of the rolled material changes. If the set tension remains unchanged, the tension control calculator (11) will make the machine constant again, so a calculator (160) is added as a means to prevent this.

Although the case in which the speed of the downstream stand is corrected is shown in 1), the speed of the upstream stand may be corrected. Furthermore, when using the deformation resistance tracking memory, if the distance between the temperature needle (2) and the stand (2) is short or the rolling speed is high, roll rotation detection device (13) and deformation resistance Tracking memory (15
) may be omitted. Mana, deformed resistance calculator (14)
Although an example has been shown in which the tension correction value is calculated after converting the temperature into deformation resistance, the same effect as in 4 can be achieved by modifying the structure so that the tension correction value is directly calculated from the temperature and tension values.

以上のように、この発明によれば連続圧延機の張力設定

することが可能となる。As described above, according to the present invention, the tension setting value of the continuous rolling mill is corrected according to the change in the rolling mill temperature, so that the width dimension can always be controlled to be constant even if the rolling mill temperature changes. becomes possible.
