Abstract

PURPOSE:To improve the accuracies of dimensions and shape of a material in a titled device, by preparing a thickness detector and a width detector provided to the inlet side of a continuous mill, an AGC device, and respectively arithmetic devices used for calculating a roll- gap correcting quantity and its influence. CONSTITUTION:An automatic dimension-controlling device, which forms the size of a material into the prescribed dimensions while the material is running by controlling a continuous mill consisting of horizontal rolls and vertical rolls, is constituted as in the following. That is, a thickness detector and a width detector are provided to the inlet side of the mill. On the other hand, a roll-gap correcting quantity is obtained by an AGC device, which calculates the thickness of material and the roll-gap correcting quantity at the outlet side of the mill basing on a rolling load and a roll gap of the mill. Then the material width which is obtained by delaying the material width detected by the width detector by a prescribed time, the thickness deviation which is obtained by delaying the deviation between the thickness detected by the thickness detector and the standard material thickness by a prescribed time, and an actual correcting quantity of roll gap basing on the roll-gap correcting quantity are calculated by the 1st arithmetic device respectively. Thus a controlling is performed by calculating the influence on the material width, caused by the roll-gap correction, by using the 2nd arithmetic device.

Description

Detailed Description of the Invention (aJ Description of Technical Separation) The present invention is a press machine equipped with a continuous stand consisting of vertical rolls and horizontal rolls, which automatically controls the material dimensions of the pressed material. It is related to the dimension control system@.

(bl Description of the prior art) In general, continuous rolling mills g2 with continuous rolling mills 1 often have a combination configuration of vertical rolls and horizontal rolls in the rough and intermediate row stand groups.Such a configuration and Article m
In continuous rolling, the roll gap is not taken into consideration during the material pressure, and is not controlled by the material.The roll gap is set according to the dimensions of the product before rolling. , the material is pressure-treated in the same state as it is, and between each stand, a looper or looper is used to reduce the tension 141, keeping the tension between the stands at a minute tension, and the material is '+till' and '+ill' are used to change the cross-sectional shape of ``kawasemi'' and indirect (two-point ne-1).

However, since it is 2, it is not possible to expect a further improvement in 1fj1 (21 cross-sectional dimensions and shape 1') using the method described above.

This is because the roll gap includes the gap with the initial setting of j, and the tension between the stands jljll (l). Even if the tension between the stands is minute or phantom, and there is no tension, the material dimension and product can be changed by this difference of 1. This is because it does not get too hot.

, in the rolling direction (in the case of horizontal rolls, the rolling line (two pairs (-
In addition, by modifying this roll gap, the material thickness 7 can be controlled in the vertical direction (in the case of water S1t rolls, in the horizontal direction, vertical roll). In the case of 1 ground direction), there will be an effect on the mouth thickness, but this material thickness will change by 1 gradual correction between the rolls of the next stand (: ζ).

(Taking into account the variation in material thickness in the vertical direction, and taking into account the reduction in the thickness of the downstream stand after the stand and the variation in the thickness of the material in the vertical direction, the next stand is The roll gap of the stand concerned is not corrected so as to reduce the subsequent particle size fluctuation outside pa., and the disadvantages of the Mil W'.

If the roll gap is controlled (in the vertical direction) from 5TNj I-, the effect will appear as thickness variation in the left and right direction, and if this is not controlled, if the thickness variation is large, the downstream There is a side stand (dimension control) 1 limit, and no matter when you cut it out, the thickness will fluctuate if there is no cutout t1. In other words, downstream 11jll is a vertical roll]

The roll gap of the core rolling mill is determined based on the gap correction word obtained from this AGO system fI- and the deviation between the material width detected by the previous Iij II detector and the reference width after a predetermined period of delay. The first operator η'' calculates the actual value of 1'''-corrected, and the second calculator calculates the effect of the actual roll 11Il gap correction on the material thickness 52. An automatic dimension control device whose mission is to (3) Horizontal roll and vertical roll are fixed)l! : The thickness of the paulownia material is set to the predetermined dimension (2) in the nm row.

A) - Detection H1, the width detection cap that also detects the width of the sick and injured material in @11, and the width of the material detected by this width excision. 52 Based on the rolling stock and the roll gap of the rolling mill, the output of the rolling mill is 11
U material J stain and roll gap correction amount are calculated by the AGC device f%+ and this AQC device faVC2. A first computing unit that divides the deviation between the obtained thickness and the reference material thickness by the amount by which the roll gap of the rolling mill is actually corrected based on the deviation by a certain period of time; A second l1iI calculator that calculates the influence on the material width due to the modification, and a second l1iI calculator that calculates the influence on the material width due to the modification, and a current m*,

■The thickness of paper detected by the detection H1 and the detection HIC2 is
1-AGO which calculates the rolling width and roll gap stop knowledge of the rolling mill based on the roll clearance and roll gap of the rolling mill.
The 1-opening difference between the material width detected by the roll gap correction-1 obtained by this A()C device and the reference material width and the reference material width is The roll gap of the 8 machines concerned is actually corrected by (16). In order to reduce the thickness variation in the downstream and Q-direction due to the above-mentioned '48: correction of the roll gap, the roll gap 11 is lowered and lowered (in the white direction). Home-made dimensions characterized by the fact that the thickness variation 1 (i- to 1 key (-soσ)) output is provided with the first performance instrument 1-7, the 3rd performance instrument. 1v control device.

The automatic dimension control device according to claim 2 or 4, characterized in that the automatic dimension control device is used in a device that performs a performance using the device. (7) The automatic size control device for the first to sixth burial mounds, wherein the AGC device is an SRA type AGO device or an absolute value AGO device. (8) Thickness variation in the rolling direction and vertical force direction by adjusting the N between the rolls of the rolling mill The thickness variation conversion coefficient in the rolling direction and the vertical force direction is corrected by taking into account the tension between two stands. Automatic dimensional control 1i ((111ull i'11.',: Principle P11; L1 rolling mill is a continuous compaction machine for steel bars and gyokusen) Approximately % similar to the automatic dimension system described in Sections 1 to 8 of Section 11.
