Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for transferring a wire rod thickness measuring device to a multi-row rolling line for wire rods, which makes it possible to measure the thickness of wire rods on any rolling line using one wire rod thickness measuring device. It is related to the device.

Figure 1 shows an outline of the layout of a conventional wire rod rolling line.

In Fig. 1, the four square steel materials that came out of the heating furnace l are
It passes through a rough rolling mill 2 and a first intermediate rolling mill 3, is divided into two directions, passes through a second intermediate rolling mill 4゜4', is sent to finishing rolling mills 5 and 5', and further passes through four rolling lines. It becomes an fFM control coil and is sent to the next process.

The second intermediate rolling mill 4.4' in the rolling line is.

It is a multi-row rolling mill, and usually uses one set of upper and lower rolls to roll steel materials in two rows. Conventionally, in these multi-row rolling mills, the difference in the number of steel sheets that are simultaneously bitten due to the influence of mill springs (in the case of two rows, 2 steel sheets per car weight) causes dimensional fluctuations in the rolled steel materials, and roll wear. We have experienced that the dimensions of the wire rods differ between rows due to differences in the degree of the steel wire and changes in the temperature of the rolled steel material.

To prevent this, conventionally samples were collected using an online shear installed in the middle of the rolling line.
By measuring the dimensions of the steel material, we understood the dimensional variation formula and took measures such as adjusting the reduction of the rolling rolls. However, since the information on the dimensions of this intermediate steel material is intermittent information obtained from sample checks, dimensional defects (deviation in deviation, bite, etc.) occur due to delays in action. In order to eliminate these drawbacks of conventional sample checking methods, thickness measuring devices that use a light source and a detector are used in some cases.

An object of the present invention is to provide a transfer device for shifting and using one thickness measuring device and a plurality of guiding troughs for guiding wire rods between multiple rolling lines. .

According to the device of the present invention, the trolley can be moved as needed.
Since the outer diameter dimension of the wire on any rolling line can be measured in a short time using a table-based thickness measuring device, the above-mentioned drawbacks in the conventional work can be improved.

Embodiments of the apparatus of the present invention will be described in detail below based on five drawings.

Fig. 2 is a plan view of the device of the present invention, and Fig. 3 is taken from BB in Fig. 2.
The cross-sectional view, FIG. 4, is a cross-sectional view taken along line AA in FIG.

The steel material rolled by the second intermediate rolling mill (not shown) is divided into two lines passing through the fixed trough 6 of the first row line in FIG. 2 and the fixed trough 7 of the second row line in FIG. Reference numeral 8 denotes a rail according to the device of the present invention, which is arranged in an arc shape intersecting (orthogonal to) the first and second lines. Trough portion 6 that intersects with rail 8
．． 7 is divided into parts where one carriage 9 passes. A guide trough or a thickness measuring device placed on one carriage 9 is shifted and set in this divided portion.

The trolley 9 is formed into an arcuate (or linear in some cases) box shape, and moves on the rails 8 by operating a hydraulic cylinder 10 fixed to the floor. The moving cart 9 is a parent cart 9
A guide trough 1'7 is provided at the tip of the parent cart 9', and a rail 12 is provided behind it. A child truck 11 loaded with troughs 13 and 14 is provided so as to be moved by a hydraulic cylinder 16 disposed on one truck 9.

That is, the child cart 11 is placed on the parent cart 9' and arranged so as to be able to move freely relative to each other.

However, depending on the case, the child truck 11 may be omitted.

The thickness measuring device may be placed directly on the trolley 9.

Next, the operation of the device of the present invention will be explained.

FIG. 5 is a diagram showing three modes of movement of the device according to the invention, in which reference numerals 6 and 7 indicate the directions of the first and second lines corresponding to the stationary trough 6.7 of FIG.

9' is the parent truck, and work 1 is the child truck + 'L3, 14. l'i
' indicates a guiding trough, and 15 indicates a thickness measuring device. FIG. 5(A) shows a configuration in which the thickness measuring device 15 is set on the first line and the guide trough 17 on the parent truck is set on the second line, and the parent truck 9' is centered around the first line. This is a diagram in which the six child carts 11 are set on the left half of the parent cart 9'.

FIG. 5(b) shows a case where there is no need to measure the dimensions of both the first line and the second line. It is a diagram in which it has been moved by a certain half span (l/2 between lines).

FIG. 5(C) shows a configuration in which the thickness measuring device 5 is set on the second line and the guide trough is set on the first line.
It is a diagram in which the parent truck 9' and the child truck 11 are further moved by half a span.

By adopting the above three working modes, one thickness measuring device can be effectively and freely shifted to a required line.

FIG. 6(A) is a diagram showing a shift form of a truck according to the present invention. A thickness measuring device 15 is provided in the center of the trolley 9,
It is symmetrical about this, and 1 of the distance between the rolling lines.
Guidance troughs are provided at 72 intervals.

Figure 6 (b) is from top to bottom, respectively Figures 5 (a), (b),
This is a shift form corresponding to (c).

The device of the present invention has such a function, and can be easily used even if a thickness measuring device is provided on each line for installation and removal.

As mentioned above, since the device of the present invention shifts one thickness measuring device to multiple lines as necessary, there is no need to manually collect and check samples as in the past. No need to worry, once you set it, you can automatically and continuously measure the specified dimensions.

The information is sent to the second intermediate rolling mill in the previous process, making it possible to control the rolling reduction of the rolling rolls. It also makes the conventional fixed thickness measuring device movable, contributing to the rational use of the device.
