Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for detecting a side weir in a twin drum continuous casting facility, a method for detecting a side weir abrasion, a method for controlling a side weir position, and a device for controlling a side weir. The present invention relates to an improvement in a method of pressing against a drum end face.

[0002]

2. Description of the Related Art As shown in FIG. 7, in twin-drum continuous casting, a pair of cooling drums 1 arranged in parallel at a predetermined interval and pressed against both end surfaces of these cooling drums 1 are used. A pair of side weirs 52 arranged in a state
And constitute a continuous casting mold.

[0003] A molten metal 54 stored in a preheating layer called a tundish 53 is continuously injected to form a pool 55 in the continuous casting mold. The metal melt 54 in contact is thinly solidified on the surface of the cooling drum 1.

[0004] Next, the pair of cooling drums 1 with the solidified metal on the surface are rotated as shown by arrows in the figure to form a strip-shaped cast piece 56 on the surface of the cooling drum 1 with the thinly solidified metal. And send it down. A predetermined amount of molten metal 54 is always supplied to the tundish 53 from a molten steel pot 57 called a ladle while the supply amount is adjusted by a stepping cylinder 58.

As shown in FIG. 7, on the back surface of each side weir 52, pressing mechanisms are provided at two places (52a, 52b) at the upper part and one place (52c) at the lower part. Via mechanisms 52a, 52b and 52c,
The front face of the side weir 52 is pressed against the end face of the cooling drum 1 by the stress applied to the back face, and the cooling drum 1 is configured to slide on the front face of the side weir 52 with rotation.

Therefore, the sliding surface between the cooling drum 1 and the side weir 52 is worn. The design including the selection of materials is performed so that the abrasion caused by the cooling drum 1 and the side weir 52 occurs preferentially on the side weir 52 side of the cooling drum 1 from the viewpoint of maintenance cost. I have.

[0007] In order to offset the reduction of the sliding surface of the side weir 52 due to wear, and to ensure a sealing effect, the side weir 52 is constantly pushed forward toward the cooling drum 1 during operation. ing.

Here, it is important that the abrasion of the side weir 52 progresses uniformly over the entire sliding surface. because,
If uneven wear occurs on the side weirs 52, the seal cannot be maintained uniformly on the entire sliding surface, local sealing failure occurs, molten metal leaks, and stable casting continues. This is because the inconvenience of not being able to do so occurs.

Also, there is a problem that uneven wear substantially shortens the life of the side weir 52. In particular, side weir 5
If there is a wear deviation between the upper part and the lower part of 2, it tends to cause hot water leakage, and thus its prevention is extremely important.

The amount of wear on each part of the sliding surface of the side weir 52 is substantially determined by the frictional force acting on the sliding surface.
The friction force is determined by the reaction force from the end surface of the cooling drum 1 to the sliding surface. Therefore, paying attention to this, the reaction force acting on the pressing mechanism provided on the side weir 52 from the end face of the cooling drum 1 was measured, and the side weir 52 was measured based on the measured value.
A method has been proposed in which the amount of forward displacement is controlled to obtain an appropriate pressing force (JP-A-3-230848).

However, as proposed in the above-mentioned Japanese Patent Application Laid-Open No. 3-230848, there has been a problem that the surface pressure on the sealing surface cannot be correctly detected only by detecting the reaction force. That is, (1) since the surface of the side weir 52 is thermally deformed, it is practically impossible to obtain a completely flat state, and (2) the crimping state at the start of pressing varies. This is because a state in which the cooling drum 1 and the side weir 52 are not in close contact with each other even though the reaction force is received occurs.

Further, if the gap between the side dams 52 is shifted due to the frictional force with the end face of the cooling drum at the start of pressing, the reaction force is increased at the gap generating portion, and the pressing load cylinder is retracted. Further, there is a problem that the gap is enlarged and the molten metal leaks.

Further, during the casting, the friction coefficient between the end face of the cooling drum 1 and the side weir 52 changes due to various causes, so that the surface pressure applied to each part of the sliding surface of the side weir 52 also changes separately. However, there is a problem that uneven wear occurs.
Factors of the change in the wear coefficient include delicate metal adhesion to the end face, change in the state of the end face unevenness, and peeling of the end face coating, which do not lead to poor sealing.

In twin-drum continuous casting, it is of great concern how the operation can be continued for a long time. As for the long-time continuous operation, how to maintain the sealing property between the cooling drum 1 and the side weir 52 is a problem.

As a material for the weir that is pressed against the metal cooling drum 1 to maintain good sealing properties, a material that does not scratch the metal cooling drum 1 and that is not easily worn is required. However, in reality, such an easy-to-use device is still being developed, and it is necessary to make the operation possible for as long as possible by devising the operation.

As described above, in the invention described in the above-mentioned publication, the side weir 52 is attached to the cooling drum 1 in accordance with the elapsed time from the start of operation in consideration of the wear of the side weir 52 at the end of the cooling drum 1. I try to push it.

[0017]

In such a case,
When the actual wear amount of the side weir 52 used in the actual operation is measured, the casting time and the wear amount do not have a fixed relationship. This means that the sealing method proposed in the above publication cannot sufficiently cope with the problem. That is, the side weir 52 is moved to the cooling drum 1 at a constant pushing speed.
Even when pressed against the end, the abrasion proceeds further and the sealing performance may not be maintained.

Further, the cooling drum 1 thermally expands as the casting time elapses. In particular, it is pointed out that the end of the cooling drum 1 in contact with the side weir 52 expands rapidly in the early stage of casting. Therefore, unless this phenomenon is accurately grasped and the above-described pushing speed is appropriately corrected, unfortunately there is a problem in that wear is inadvertently accelerated, and conversely, the sealing property cannot be maintained.

The present invention has been made in view of the above-described problems, and has been made to reduce the amount of wear on the side weirs so as to increase the durability and to maintain good sealing between the cooling drum and the side weirs. The purpose is to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a method for detecting the amount of side weir wear, a device for detecting the amount of side weir wear, a side weir position control method, and a side weir position control device for a twin drum continuous casting facility according to the present invention will be described. This will be described with reference to FIG.

FIG. 1 is a block diagram showing an embodiment of the present invention and showing a configuration of a side weir abrasion detecting device. As shown in FIG. 1, the side weir amount detection device of the present embodiment includes a position detection unit 11, a reaction force detection unit 12, a stiffness detection unit 13, a thermal expansion characteristic detection unit 14, and a wear amount detection unit 10.
It is constituted by.

As shown in FIG. 7, the position detecting means 11 detects the amount of pushing of a pair of side weirs 52 disposed on the end faces of a pair of cooling drums 1 arranged opposite to each other at a predetermined interval. The detection result is used as a position detection signal S11 as a wear amount detection means 1.
Output to 0.

The reaction force detecting means 12 is provided for detecting the reaction force applied to the side weir 52, and outputs the detection result to the wear amount detecting means 10 as a reaction force detection signal S12. I do.

The rigidity detecting means 13 is provided for detecting the rigidity of the mechanism for supporting the side weir 52, and outputs the detection result to the wear amount detecting means 10 as a rigidity detection signal S13. .

The thermal expansion characteristic detecting means 14 is provided for detecting the thermal expansion characteristic of the cooling drum 1 which changes with the lapse of time from the start of operation of the twin drum continuous casting facility. The detection result is output to the wear amount detecting means 10 as a thermal expansion characteristic detection signal S13.

The wear amount detecting means 10 includes signals S11 to S11 input from the position detecting means 11, the reaction force detecting means 12, the stiffness detecting means 13 and the thermal expansion characteristic detecting means 14, respectively.
A predetermined calculation is performed using S14, the amount of wear of the side weir 52 is detected, and a wear amount detection signal S10 is output.

The calculation performed by the abrasion amount detecting means 10 is as follows: the amount of abrasion of the side weir 52 = the amount of indentation− (measurement reaction force (F) / support mechanism rigidity (M)) − reaction force (F) dt ± drum heat The expansion is performed using the following equation (1).

In the above (Equation 1), the pushing amount and the reaction force are measured by a sensor. Also, since it is difficult to measure the amount of expansion of the cooling drum 1, it is approximated by a first-order time function as shown in a characteristic diagram showing the relationship between the time and the amount of expansion as shown in FIG. The correction amount is determined by timing. Further, the support mechanism rigidity (M) uses a value obtained off-line.

Incidentally, the expansion of the cooling drum 1 is different between the drive side DS and the work side WS in the cooling drum 1. This is the cooling drum 1
When the cooling water 40 is supplied to the inside of the drum shaft, it is supplied from the drive side DS side of the drum shaft 41 as shown in FIG.

Therefore, the temperature distribution in the cooling drum 1 is low on the drive side DS side and high on the work side WS side. In particular, as shown by shading in FIG. 4, the temperature near the end of the cooling drum 1 is high.

Because of such a temperature distribution characteristic, the amount of pushing in the side weir 52 on the drive side DS side is normally properly set and the sealing property is kept good, but the casting is started. After about 30 minutes have elapsed from the start of the wear, the wear progresses and a gap is generated slightly.

On the other hand, since the work side WS has a high temperature, the thermal expansion of the cooling drum 1 is large, and the side weir 52 is pushed into the cooling drum 1 more than expected in synergy with the pushing amount. . This means that the side weir 52 is worn by humans.

It is known that various problems occur if the pushing amount of the side weir 52 is not set properly. For example, when the side weir 52 is pushed too much, the wear proceeds, and the casting time becomes extremely short. Conversely, if the pushing amount is insufficient, the sealing performance is reduced, and hot water leaks between the cooling drum 1 and the side weir 52.

On the other hand, in the present embodiment, since the amount of wear of the side weir 52 is accurately detected as described above, it is necessary to determine the amount of pushing from the cooling drum 1 according to the true gap. Can be.

At 21, the amount of pushing of the side weir 52 is detected.

Next, the process proceeds to step S21, where the reaction force of the side weir 52 is detected. The detection of the pushing amount and the detection of the reaction force are performed by the sensor (not shown) provided on the cooling drum 1 as described above.

Next, the process proceeds to step S23, where the side weir 5
The rigidity of the mechanism supporting 2 is detected. Then, in step S24, the thermal expansion characteristic of the cooling drum 1 that changes according to the elapsed time since the twin-drum continuous casting facility started operation is detected. These detections are performed off-line, as described above.

Next, in step S25, a predetermined calculation is performed using the values obtained in the above steps, and the amount of wear of the side weir 52 is detected. The detection of the amount of wear is performed by sequentially performing the processing described above.

Next, the routine proceeds to step S26, where it is determined whether or not to continue the processing for detecting the amount of wear. As a result of this determination, if the processing is to be continued, the process returns to step S21 and the above-described processing is repeated. If the process is not to be continued, the process ends.

A weir pressing means 51 is provided.

The side weir pressing means 51 is for pressing the side weir 52 against the cooling drum 1 based on the calculation result of the pressing amount calculating means 50.

2 can be automatically performed, and labor saving and stabilization of operations performed using the twin-drum continuous casting facility can be greatly improved.

In step S62, the side weir 52 is used on the basis of the calculation result obtained in step S61.
