を図ることかで暑るようにすることにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for detecting roll alignment in continuous casting equipment, and its purpose is to detect roll alignment at all times during operation, thereby improving low-V alignment. Slabs due to F defects (hereinafter referred to as 1 lath)
The aim is to prevent quality deterioration and reduce the number of operational stoppages due to unexpected accidents.

する方法があった。Traditionally, methods for detecting roll alignment in continuous casting equipment include measuring it manually using a measuring instrument during non-operations, or using devices such as roll spacing measuring devices or roll rotation detection devices during non-operating periods. There was a method for measuring by remote control.

また従来はこのような突発事故の頻度が高いため。Specifically, the former method of artificially measuring using measuring instruments includes measuring the roll level V with a level V gauge, measuring the roll outer diameter with a caliper, measuring low A/an with a dial gauge, and using a thickness adjustment gauge. El, 4/between 11
1IiIl constant and manual roll rotation checker, visual bearing inspection, etc. These former methods require one person to enter the machine, i.e. Row A/I#, and m
Since key V alignment cannot be detected at all during operation, it is possible to grasp the ever-changing low V alignment>0@ shift, predict slab quality O14 to 41s1, and take measures such as changing operating methods to deal with this. In order to prevent the quality of the system slab from deteriorating, it is not recommended to perform planned low-V replacements at the next maintenance day or at repair opportunities such as mold replacements.
I was the total. Therefore, in the former method, the abnormality of slab quality due to sudden roll alignment failure or low ivm**o
*It is impossible to prevent accidents from occurring, and sudden accidents can force long-term suspension of operations], which is a factor in reducing the operating rate of continuous casting equipment. ,
Also, in the past, such sudden accidents were more frequent.

であった。It is difficult to plan and maintain spare rolls for replacement, so it is necessary to have a large number of spare rolls, and the cost of maintaining them is also high.Furthermore, since the measurement is done manually, it requires a lot of effort. As if it were a fool, the danger was also extremely high.

Although it is an indicator of L/alignment management, it cannot be said to be a sufficient means of detecting roll alignment.

Roll alignment, casting conditions, and drive tube for drawing slabs
It has a function that calculates the relationship between the current value of the Lemaux warehouse, and the required current value of the motor is calculated from the latest roll alignment and casting conditions that are heated in advance at the start of operation 1, and the current value that is measured during operation. The actual roll alignment is detected by comparing the measured am value of the motor and calculating the amount of change in roll alignment from the difference.This will be explained below with reference to the drawings.

It is continuously transferred to the next process. That is, for drawing out the slab (6), two drive rolls (4) are appropriately arranged between the non-drive rolls (4) and the non-drive rolls (3), and each of these drive rolls (4) is Motor +

流は減少することになる。Here, the cause of the roll alignment failure due to one roll (3) and (4) will be analyzed based on Figure 2). As shown by the broken line, if the drive row A/(4) By applying unnecessary bending force to 6), the pull-out resistance at σ-A/(4)& increases, and therefore the current of the motor (5) that drives the low A/(4)& increases. It turns out. Similarly, if the distance between drive rolls (4)b and (4)00 at opposing positions becomes narrower than the normal dimension, as shown by the broken line, the pulling resistance increases and the first roll (

and appear. Conversely, if the level of roll S (4) a is low, and the distance between rolls (4) b and (4) o becomes wider, the pull-out resistance becomes smaller and the current of the corresponding motor (6) decreases. I will do it.

The rotation speed of this roll (4) d is the same as the rotation of the ag driving motor (6) of the roll (4).

The fact that y(4) A acts as a brake acts as an extra load on the other drive rolls (4) and drive iIb motor a (5), so the current in those drive motors (6) increases. I will do it.

In the case of low rotation (low N0) due to bearing failure, the extraction load similarly increases and the current of the motor (5) increases.

First, the latest roll alignment data (4), which was manually measured in advance on a maintenance mortar or the like before the start of operation, is entered into the memory function of the calculation 1ml monument device (7) using $-&-F (8). At the same time, immediately before the charge is cast into the steel 1111, the keymate (8) similarly calculates the casting condition data (B) such as the billet size, molten steel temperature, steel type, cooling pattern, etc. ) into the memory function.

する。また。The calculation is performed by taking several moderate predetermined points detected by the casting speed needle, and is stored as the required current value at the predetermined casting speed, and after starting casting, the casting speed is calculated. When the speed detected by the meter reaches a predetermined speed calculated from the required current value of 1 m, the value of the current flowing through each motor (6) is measured by the ammeter (9), and the current value *1 is calculated. The value is compared with the required current value by the calculation I control device (7), and the difference is calculated. From this difference in DC value, the Jiro M alignment defect is calculated backwards using the calculation formula, and the cause and numerical value are calculated. The changes in the output data are recorded on I# (B), recorded on Nolinta (B), and further displayed on 0RT (To).
