Description

Measuring Apparatus for Three Dimensional Flow Field of Plate Surface

According to the present invention, in order to analyze the collision pressure of a high-speed jet sprayed on a steel plate surface such as a strip or a coil, the impact pressure applied to the flat surface surface when the high-speed jet collides with a plate corresponding to a steel plate such as a strip or a coil is three-dimensional. In more detail, the present invention relates to a device for measuring the pressure of a strip, and more specifically, to obtain a collision pressure information of a strip surface formed when a high-speed jet flow injected from an air knife collides with a strip (steel plate) surface in a continuous hot dip plating process. The present invention also relates to an apparatus for measuring three-dimensional impact pressure information of a coil surface formed at a coil surface by an impingement jet of air or water upon cooling of a heated coil.

In general, in a continuous hot dip plating process, the steel sheet plating equipment has an air knife for controlling the thickness of the plating solution adhered to the surface of the steel sheet by spraying a gas of an appropriate pressure on the surface of the steel sheet (strip).

The main part of a strip plating machine with an air knife is schematically shown in FIG.

As shown in FIG. 1, the steel sheet 1 is moved along a path rising in the vertical direction after passing through a bath filled with a plating solution such as zinc, and the air knife 20 moves on both surfaces of the steel sheet passing through the bath. It will inject gas into it. That is, the molten metal is blown off by blowing the gas toward the steel sheet 1 from the nozzle of the air knife 20 so that the molten metal attached to the steel sheet 1 can uniformly obtain the target plating thickness in the width and length directions of the steel sheet. .

2 is a view showing a state in which a gas is injected in the conventional air knife 20 to form a jet stream.

As shown in FIG. 2, the air knife 20 has a main body 23 having an open part for discharging gas, and is installed at an open part of the main body 23 so that the gas is injected at a high speed to generate a high speed jet. It includes upper and lower ribs 24, 25 forming a nozzle to form. The air knife 20 allows a gas made of air or nitrogen gas to be supplied to the main body 23 at a proper pressure by a blower and injected into the steel sheet 1 through the upper and lower ribs 24 and 25.

The width of the nozzles formed on the upper and lower ribs 24 and 25 of the air knife 20 is formed to be larger than the width of the steel sheet to be plated, and the discharge direction of the gas injected from the nozzle is in the traveling direction of the steel sheet. It is set to be perpendicular or opposite to the direction.

Thus, the plating thickness and plating quality obtained by the high speed jet sprayed from the air knife 20 largely depend on the magnitude of the collision pressure of the high speed jet impinging on the surface of the steel plate 1 and the uniform pressure distribution in the width direction.

Therefore, in order to secure the target plating thickness and high quality of the plated steel sheet, it is essential to obtain flow information such as impact pressure along the width direction, the longitudinal direction and the radial direction on the high speed jet and the steel sheet surface.

3 and 4 is a perspective view briefly showing a conventional collision pressure measuring device.

As shown in Figs. 3 and 4, the conventional crash pressure measuring apparatus drills a plurality of pressure measuring holes 11 in a line or a specific portion in the crash plate 10 corresponding to the steel plate 1 such as a strip. The pressure measuring hole 11 is drilled on the collision pressure applied to each of the pressure measuring holes 11 from the high speed jet injected from the air knife 20.

At this time, each pressure measuring hole 11 is connected to the tube 40 to measure the pressure applied to each pressure measuring hole 110 using a pressure sensor (not shown) such as a differential pressure sensor.

However, since the impact plate 10 is fixed to the frame 30, such a conventional collision pressure measuring device can only measure the point where the pressure measuring hole 11 is installed, so that only two-dimensional flow information can be obtained.

That is, as shown in FIG. 5, the conventional collision pressure measuring apparatus can measure only the two-dimensional collision pressure distribution in the width direction of the collision plate 10 (corresponding to a steel plate such as a strip) at a specific point. The two-dimensional measurement method has a problem that it is not possible to determine the spatial, that is, three-dimensional impact pressure distribution of the strip surface formed by the collision jet.

In addition, in order to measure the pressure at a plurality of points of the impingement plate 10, a plurality of pressure measuring holes 11 are formed, and each of the pressure measuring holes 11 has a tube 40 and a pressure sensor connected thereto. Since each must be installed, there is a problem that the tube 40 and the pressure sensor takes more than necessary.

In the above, the case of measuring the impingement pressure formed on the surface of the strip when the high-speed jet flow from the air knife collides with the surface of the strip (steel plate) in the continuous melt plating process, for example, but this problem is The same occurs in the case of the impact pressure measurement of the coil surface formed on the coil surface by the impingement jet of air or water during cooling of the heated coil.

Therefore, a three-dimensional collision pressure measuring apparatus that can solve this problem is required.

On the other hand, although not shown in the drawings, the guide member may be installed to limit the rotational movement of the left and right transfer member 165, but only linear movement in the left and right direction, and the configuration of such a guide member is known in various forms, so Description is omitted.

In the above, the upper and lower conveying unit 150 and the left and right conveying unit 160 are made of a screw member to convert and rotate the rotational movement of the screw member to the vertical movement in the vertical or horizontal direction, but the upper and lower conveying unit 150 ) And the left and right transfer unit 160 is not limited to this embodiment.

In addition, in the present specification and FIGS. 6 and 7, the vertical conveying unit 150 is connected to the frame 110, the left and right conveying unit 160 is connected to the vertical conveying unit 150, and the collision plate is connected to the left and right conveying unit 160. Although illustrated and described as being, the left and right conveying unit 160 is connected to the frame 110, the left and right conveying unit 160 may be configured to be connected to the collision plate 130 through the upper and lower conveying unit 150.

On the other hand, the three-dimensional impact pressure measuring apparatus 100 according to the present invention may further include a pressure measuring unit 190 for measuring the pressure of the jet introduced into the pressure measuring hole 131.

The pressure measuring unit 190 measures a plurality of tubes 140 connected to each of the pressure measuring holes 131 and the pressure of the jets connected to the tube 140 and introduced into the pressure measuring holes 131. A pressure sensor 170 including a differential pressure sensor or the like, and a data processor 180 corresponding to a digital data acquisition (DAQ) system or the like may be provided to process the pressure measured by the pressure sensor 170 as data. The data processor 180 may be a computer or the like as an example.

On the other hand, in the case where a plurality of pressure measuring holes 131 are installed more than necessary, a plurality of tubes 140 and pressure sensors 170 are required, which may be inefficient. Therefore, as shown in FIG. 8, the pressure measuring holes 131 may be formed in a line in the width direction of the collision plate 130. That is, the three-dimensional collision pressure measuring apparatus 100 according to the present invention installs a plurality of pressure measuring holes 131 in a line in the width direction of the collision plate 130 and transfers the collision plate 130 in the left and right or up and down directions. Since the collision pressure can be measured while the pressure measuring hole 131 is provided only in one line in the width direction, the three-dimensional collision pressure can be measured.

In addition, since the impact pressure changes more at both ends of the width direction than at the center of the collision plate 130, the distance between the pressure measuring holes 131 is shorter at both ends than the center to effectively secure the flow characteristics of the edge portion of the steel plate surface. It is preferably formed so that.

In addition, the collision plate 130 is installed to the left and right conveying member 163 so as to detach the collision plate 130 having various sizes or the collision plate 130 having pressure measuring holes 131 of various shapes. By installing the pressure measuring device, various collision pressure measurements are possible.

It looks at the effect of the three-dimensional impact pressure measuring apparatus according to an embodiment of the present invention having the configuration as described above.

First, referring to FIGS. 6 and 7, the impingement plate 130 is fixedly installed to the left and right conveying units 160 with bolts and the like, and pressure sensors such as tubes 140 and differential pressure sensors are provided in the pressure measuring holes 131. 170 and DAQ Connect a data processor 180 such as a system.

Thereafter, the upper and lower conveyers 150 are adjusted to adjust upper and lower teeth of the impingement plate 130 so that the nozzle center of the jet injection means 120 and the center of the pressure measuring hole 131 of the impingement plate 130 coincide with each other. In addition, the left and right transfer unit 160 is adjusted to adjust the nozzle of the jet injection means 120 to coincide with the center of the width direction of the collision plate 130.

As such, when the high speed jet is injected through the jet injection means 120 after the basic adjustment is completed, the high speed jet collides with the collision plate 130, and the high speed jet opens the pressure measuring hole 131 of the collision plate 130. It is transferred to the tube 140 through the pressure sensor 170 is sampled at a desired period and the impact pressure is stored in the data processing unit 180, such as a mobile DAQ system.

As a result, the two-dimensional collision pressure is measured in the width direction of the collision plate 130.

Subsequently, when the collision plate 130 is measured while moving in the vertical direction or the left and right direction, it is possible to measure a three-dimensional, that is, three-dimensional collision pressure on the entire surface of the collision plate.

In order to achieve the high speed of the continuous hot-dip plating line, the biggest problem is that the flow of the high-speed jet emitted from the nozzle of the jet jetting means such as the air knife hits the strip moving at high speed. Problems on the surface of the strip due to problems (commonly called splash), overplating of the edges of the strip due to the three-dimensional behavior of the high speed jet flow, and vortex flows developed within the wall jet flow along the strip surface. Flow patterns (commonly referred to as check marks) and the like are factors that make the superposition of the hot dip plating and the high quality of the hot dip plating difficult.

In particular, since the conventional collision pressure measuring apparatus shown in Figs. 3 and 4 measures the collision pressure at a specific position or in a line direction, it is possible to obtain a maximum collision pressure value at a specific portion, but as described above. This is the cause of undesirable phenomena. In fact, the jet flow has many vortex flows in the width direction of the wall collision jet in the cross section of the wall impingement jet, and the cross section of the jet impinges the characteristics of vertical, horizontal and asymmetric flows instead of symmetrical flow. Pressure measurement cannot analyze these phenomena.

However, according to the three-dimensional impact pressure measuring apparatus according to the present invention, as shown in Figure 9, the characteristics of the three-dimensional behavior of the impact pressure (flow field) due to the collision of the high-speed jet and the strip surface, that is, three-dimensional on the strip surface Since the impingement pressure distribution can be grasped, it is possible to achieve super high speed of continuous hot dip plating and to produce high quality hot dip coated products.

That is, according to the three-dimensional impact pressure measuring apparatus according to the present invention, since the collision pressure is measured while moving the collision plate vertically and / or left and right by using the transfer device, the obtained data are combined, so that a large area on the strip surface can be easily obtained. You can get the flow information for. In addition, the three-dimensional, i.e., impact pressure distribution over the strip surface thus obtained has the advantage that it can be effectively used to identify the cause of the splash pattern, the cause of the over-plated and molten plated steel sheet surface of the strip edge portion.

In addition, according to one aspect of the present invention, by configuring the three-dimensional collision pressure measuring device to be movable, it is possible to check the performance of the nozzle when installing the jet injection means in a number of sites, the current of the nozzle of the jet injection means used for a long time By easily verifying the condition, it is possible to prevent the quality of the steel sheet from deteriorating due to the aging of the nozzle in advance.
