Description

DEVICE AND METHOD FOR SETTING THE CASTING WIDTH AND TAPER OF MOULD NARROW FACE OF CONTINUOUS CASTING MACHINE}

The present invention relates to an apparatus and a method for setting the short side casting width and the inclination of a playing mold in a continuous casting machine, in particular, the upper and lower lateral width of the mold short side is accurately measured as a laser sensor, and the mold short side Is adjusted to 0% inclination and then the top width is adjusted to be close to the set slope of mold short side. It is about a method.

In general, the mold 1, which is a continuous casting facility, is tundished between a mold long side 2a and a mold short side 2b which are cooled by a water jacket 3, 4 as shown in FIG. Tundish molten steel is injected to produce cast steel.

At this time, the spring package 8 and the clamping cylinder 9 provided in the mold main body 10 closely contact the mold long side 2a and the mold short side 2b with an appropriate surface pressure to prevent leakage of the molten steel from the mold 1. In addition, the leaf spring 7 supports four points of the mold 1 that is oscillated stably.

In addition, the mold width changing motor 5 and the mold width changing spindle 6 maintain the mold 1 in the initial state of casting, and move the mold short side 2b for casting to obtain a casting width suitable for the product specification. The inclination of the mold short side 2b is set so that bursting of the solidification shell does not occur during casting.

Here, depending on how precisely the width and the inclination of the initial mold short side (2b) of the casting is set, it is possible to reduce the inherent size deviation amount of the cast continuously generated during the variable width casting operation.

Meanwhile, a conventional mold short side width adjusting method for setting a casting width suitable for a continuous casting operation is illustrated in FIGS. 2 and 3.

This conventional method is to measure the upper and lower end widths of the mold short sides 2b and adjust the short side widths to the set casting width. When the bottom width is to be measured according to the conventional method, the operator's arm does not touch the bottom edge portion of the mold 1, and thus it is not practical to measure it. Therefore, the operator measures the upper end width w1 of the mold short side 2b with a tape measure 12 as shown in FIG. 3, and then adjusts the lower end width w2 of the mold short side 2b with the naked eye.

Then, as shown in FIG. 2, the base 21 of the inclination measuring device 20 is placed over the upper end of the mold long side 2a, and the upper and lower measuring points 22 and 23 closely adhere to the mold short side 2b. In this case, the slope of the short side is displayed on the display screen 24.

At this time, while looking at the inclination of the mold short side 2b displayed on the display screen 24 of the inclination measuring device 20, the short side 2b using the mold width changing motor 5 and the upper and lower width adjusting spindles 6a and 6b. Finely adjust the slope and bottom width.

Therefore, the lower end width w2 of the mold short side 2b, which is measured by the neck of the operator as an approximate value, may inevitably generate a deviation, which in turn causes a deviation in the casting width. In addition, when casting is imminent, the lower end width of the mold short side 2b is set in order to set the inclination of the short side first rather than the bottom width w2 of the short side 2b to prevent the solidification shell from bursting rather than the width of the mold short side 2b. There is greater room for deviation.

In addition, the mold short side (2b) in proportion to the number of casting of the mold is measured by the tape measure 12 of the upper end (w1) hardly wear occurs because the lower edge is mainly worn, as shown in Figure 3 Afterwards, it is almost impossible to accurately apply the amount of wear of the nonlinear bottom edge to the bottom width w2 calculation. Therefore, the occurrence of the deviation DELTA W is inevitable.

The present invention improves the productivity of the mold width adjustment operation by adjusting the casting width by accurately measuring the upper and lower widths of the mold short sides, and the mold width measurement operation is simply standardized, the accuracy of the measurement data is improved to improve the quality of the cast steel It is an object of the present invention to provide an apparatus and a method for setting a casting width of a playing mold short side.

In addition, the present invention provides an apparatus and method for setting the casting width of the playing mold short side which can stably operate the equipment by minimizing the occurrence of break-out during casting by optimally adjusting the inclination angle of the mold short side.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

5 and 6 show the casting width and the slope setting apparatus 100 of the playing mold short side according to the present invention in detail.

The casting width and the inclination setting device 100 of the playing mold short side according to the present invention has a plurality of laser sensors 126 to maintain a predetermined interval up and down on the frame 120 extending downward into the playing mold (1) The width w1 (w2) between the upper and lower ends of the mold short side 2b is measured and output to the outside through the controller 136.

The body frame 120 may be made of aluminum material to achieve a light weight, and a level stand 125a is attached to an upper portion thereof, and stand blocks 127 are integrally attached to both ends of the level stand 125a.

When the water level 125 is installed at the center of the upper surface of the level stand 125a and the main frame 120 is mounted on the mold long side 2a, whether the level stand 125a is horizontal Let the operator know. A plurality of level adjusting screw holes 127a are formed in the stand block 127, respectively.

In the level adjusting screw hole 127a, a seating jaw 127b is formed in the middle of the inner circumferential surface thereof, and a stand pin 124 is inserted to span the seating jaw 127b. The level adjustment bolt 128 is screwed so as to be located at the top of the

In particular, the stand pin 124 has a seating jaw 124a formed at the lower side thereof, and when the stand block 127 is fixed to the mold long side 2a, the seating jaw 124 is mounted at the upper edge 1a of the mold long side 2a. 124a is interviewed and supported.

In addition, the body frame 120 is mounted with a semi-cylindrical seating rod 129a and 129b in the center while maintaining a predetermined interval up and down, and the seating rods 129a and 129b have a circular bar-shaped space bar. 122 are fitted respectively. These space bars 122 respectively support the rear ends of the sensor fittings to be described later. Although two space bars 122 are shown in FIGS. 5 and 6, they may be arbitrarily selected according to a casting width among a plurality of space bars having different lengths, respectively, and fixing pins 122a protruding from one side thereof. The mounting holes 129a and 129b are inserted into and fixed to the fixing holes 129a 'and 129b', respectively.

In addition, a pair of fasteners 130a, 130b, 132a, and 132b for fixing the sensor mounting holes are located on the left and right sides of the seating posts 129a and 129b, respectively. 129b is attached to the front surface of the main body frame 120 at left and right sides thereof, and fixing screw holes 131a and 131b are respectively inserted into the fixing bolts 131 in the middle thereof.

Here, the sensor mounting holes 121 are fixed to the fixtures 130a, 130b, 132a, and 132b, respectively, and since they have the same configuration, only one of them will be described in detail. The same applies to each.

The sensor mounting holes 121 are provided with key grooves 129a in the longitudinal direction along the outer circumferential surface of the support shaft 129 inserted and inserted into the fixtures 130a, 130b, 132a, and 132b. The fixing bolt 131 is inserted into and tightened through the fixing screw holes 131a and 131b of the fasteners 130a, 130b, 132a, and 132b. It is coupled to the fixtures 130a, 130b, 132a, and 132b to prevent rotation and axial movement.

In addition, the sensor mounting holes 121 are formed with recesses 121a for embedding the laser sensor 126 in the outer side of the support shaft 129, respectively, and cover 126a to protect the laser sensor 126. ) Is covered.

The laser sensor 126 scans the laser beam through the front opening of the sensor mounting hole 121 and then detects the measurement distance using the laser beam reflected from the mold short side 2b. To this end, the laser sensor 126 is provided with a light emitting unit and a light receiving unit on the upper and lower sides. When the laser beam is irradiated from the light emitting unit to the mold short side 2b, the laser light is reflected from the mold short side 2b, and the light receiving unit is provided. This is detected by the to measure the distance between the mold short side (2b).

On the other hand, since the laser sensor 126 has a short measuring range, if the distance between the mold short side 2b is too long, the entire width of the mold short side 2b cannot be measured. Therefore, the space bar 122 whose length is selected according to the casting width of the mold 1 is fitted to the seating posts 129a and 129b, so that the sensor mounting holes 121 mounted to the fixtures 130a and 130b are provided. It is located between the rear support shaft 129 of. Therefore, the space bar 122 maintains the distance between the support shafts 129 on both the left and right sides so as to be far from each other, thereby allowing the laser sensor 126 to approach the mold short side 2b by the space bar 122. As a result, the entire width of the mold short side 2b can be measured accurately.

On the other hand, holes 140a and 140b are formed in the main body frame 120 at the upper sides of the seating posts 129a and 129b, respectively, and zero adjustment bars 147 are fitted into the holes 140a and 140b. . Then, the horizontal support 138 for maintaining the horizontal level of the zero adjustment bar 147 is attached to the main body frame 120 so as to be located on both sides of the mounting holes (140a, 140b).

The zero adjustment bar 147 is a reference chuck. When the space bar 122 is replaced according to the casting width of the mold 1, the laser sensor 126 whose mounting position is changed is exactly the width of the mold short side 2b. Make sure that you measure in advance.

That is, the zero adjustment bar 147, which is manufactured with the average width or the maximum production width of the cast product as the reference length, is respectively inserted into the mounting holes 140a and 140b, and the zero point adjustment is performed by the repositioned laser sensor 126. The distance to the both ends target part 147a of the bar 147 is measured, respectively. And it is checking whether the said measured value is correct.

The operator measures the actual distance from the laser sensor 126 to the target portion 147a at both ends of the zero adjustment bar 147 as a scale calculation and then to the target portion 147a at the both ends using the laser sensor 126. By comparing the distance detection measurement with, the laser sensor 126 determines whether the correct measurement value is detected, and the laser sensor 126 and the control device 136 are calibrated to obtain an accurate measurement value.

As shown in FIG. 8, the ball spacers 137 mounted on the front and rear surfaces of the main body frame 120 in opposite directions so as to be located at the left and right sides of the mounting holes 140a and 140b are respectively viewed. It is provided with a hollow fixing tube 135 accommodated therein 133, the fixing tube 135 is fixed to the front and rear surfaces of the body frame 120, respectively, the spring 134 under the ball 133 It is built so that the ball 133 is elastically projected toward the front side.

The ball spacer 137 is supported so that the lower portion of the body frame 120 is located in the middle of the width direction between the mold long side 2a while the embedded ball 133 is elastically in close contact with the mold long side 2a. The shaking of the frame 120 is prevented.

On the other hand, the control device 136 is electrically connected to the laser sensor 126 and receives the measurement data from the laser sensor 126 and outputs it to the outside as a numerical value, as shown in Figure 9, the laser sensor 126 And a plurality of sensor plugs 136b, which are electrically connected to the liquid crystal display 136a, which is a data output unit for indicating a value from the figure, to the outside, and the conductive wire 136i from the laser sensor 126.

Then, the control device 136 has a microcomputer 136c, which is a data operation unit, and its function keys 136d, and outputs a power input terminal 136e and its result as a printed matter on one side of the microcomputer 136c. 136f, and has a sensor controller 136g.

Therefore, the measurement width of the mold short side 2b detected by the laser sensor 126 is transmitted as an analog signal to the sensor controller 136g in the control device 136 via the sensor lead 136i, and the microcomputer 136c. Is converted into a digital signal by adding the lengths of the space bar 122 and the sensor mounting holes 121 on both sides to display the detected value of the short width of the mold 1 numerically on the LCD screen 136a. do.

In addition, the control device 136 selects the type of the mold short side 2b and the type of the space bar 122 as the function key 136d, and inputs the set lower width and the inclination% of the mold short side 2b. The data for which the difference between the set input value and the measured detection value is calculated by the microcomputer 136c indicates the taper amount (mm) and width deviation of the mold short side 2b on the liquid crystal display 136a.

That is, on the LCD screen 136a, the type of the mold short side 2b (the upper and lower side trajectories are linear or curved) and the type of the space bar 122 based on the bottom width of the mold short side 2 are selected. If the lower width and the taper (%) of the mold short side 2 are inputted, the taper amount (mm) and the width deviation of the current mold short side 2b appear. And, if necessary, this output value is printed as the printer 136f.

Hereinafter, the effect of the present invention will be described.

First, when the product design of the product to be cast is determined, the space bar 122 is selected according to the width of the slab of the object to be measured and seated on the seating posts 129a and 129b, and then the zero adjustment bar 147 is mounted to the mounting hole ( 140a) and 140b respectively.

Then, a switch (not shown) of the control device 136 is operated to scan the laser light from the laser sensor 126 to the target portions 147a of the zero point adjusting bar 147, and reflect the laser light reflected therefrom. The width detection accuracy of the laser sensor 126 is compared by comparing whether the detected value measured and received and the reference value by the scales from the laser sensor 126 to the target portions 147a of the zero point adjusting bar 147 coincide with each other. Will be confirmed.

Then, the controller 136 selects and enters the type of the mold short side 2b and the type of the space bar 122, and inputs the bottom width and the slope of the mold to be produced. On the other hand, after confirming that the width detection accuracy of the laser sensor 126 is good as described above, each of the zero adjustment bar 147 is removed from the frame 120, the frame 120 as shown in FIG. It is inserted into the mold 1 as well.

In this case, the stand block 127 is placed on the center of the upper surface of the mold long side 2a so that the seating jaw 124a of the stand pin 124 is placed, and then the level adjusting bolt 128 is located while watching the water level 125. To level the level stand 125a.

Then, the laser sensor 126 scans the laser beam by the switch operation of the control device 136, and measures the upper and lower widths of the mold short sides 2b on the left and right sides, respectively. Output to the outside, and the deviation between the set value and the measured value of the mold short side (2b).

Next, the operator sets the lower end width w2 of the mold short side 2b to be produced by inputting the upper and lower width measurement values of the mold short side 2b output to the outside from the control unit 136 to the control unit 136. In accordance with the above, the mold short side 2b is adjusted to a vertical state with a taper of 0%. That is, the operator changes the mold width changing motor 5 and the upper and lower mold width changing spindles 6a through a separate mold position control panel (not shown) so that the measured lower width value output from the control device 136 matches the set lower width. Operate (6b). Then, the upper and lower width measured values continuously output from the control device 136 are adjusted to match the set lower width, and then the mold short side 2b is positioned in a vertical state with a taper of 0%.

In this case, the taper 0% of the mold short side 2b means that the top width w1 and the bottom width w2 of the short side 2b are the same as each other, as shown by a) in FIG. 11, and thus the short side 2b. I'm talking about the state of being vertical.

As such, when the adjustment of the taper 0% of the mold short side 2b is completed, the operator converts the mold short side 2b into a tapered state while gradually reversing only the upper variable spindles 6a as shown in b) of FIG. 11. When the detected inclination value of the mold short side 2b continuously measured by the laser sensor 126 coincides with the set inclination value already input to the control device 136, the operation of the mold short side by stopping the operation of the upper variable spindle 6a ( Casting width and inclination of 2b) are adjusted simultaneously.

On the other hand, in order to match the casting width and the inclination of the mold short side (2b) as shown in FIG. 11 b in the above, if the lower variable spindles 6b is stopped, and the position is adjusted while reversing only the upper variable spindles 6a, The actual casting width w3 of the mold short side 2b is somewhat smaller than the set bottom width w2. The reason is that the mold short side 2b rotates about the lower variable spindles 6b due to the pulling of the upper variable spindles 6a, and the lower edge of the mold short side 2b is set to the lower end width (b) due to the rotation. w2) is entered into the inside, and the actual casting width w3 is smaller than the set lower width w2.

However, the mounting position of the lower variable spindles 6b is always connected to a fixed position with respect to the lower edge of the mold short side 2b, so that any of the mold short sides 2b due to the pulling of the upper variable spindles 6a is arbitrary. It can be seen that the inclination of causes a lower edge displacement of the mold short side 2b which is always proportional to the inclination.

Therefore, the casting width w3 of the cast steel to be produced can be plotted according to the inclination of the set lower end width w2 and the mold short side 2b, and the operator can cast the casting width w3 of the cast steel to be produced from the chart. The set lower end width w2 of the mold short side 2b corresponding to) can be input to the control device 136. Then, the taper 0% of the mold short side 2b is adjusted based on the set lower width w2, and then only the upper variable spindles 6a are reversed to adjust the inclination of the mold short side 2b. The actual casting width w3 of (2b) can also be obtained correctly according to the inclination.

Even in such a setting operation of the inclination, the upper and lower end width detection signals of the mold short sides 2b are continuously provided from the laser sensor 126 to the control device 136 in the apparatus of the present invention, whereby the position of the control device 136 is adjusted. The current upper and lower widths and inclinations of the mold short sides 2b are output in real time. Therefore, the mold short sides 2 are inclined so as to match the set lower width and the inclination of the control device 136 previously input using the upper and lower widths and the inclinations detected in real time.

Hereinafter, a method for setting the short side casting width and the inclination of the playing mold according to the present invention will be described in detail with reference to FIG. 12.

In the method of the present invention in FIG. 12, first, step 210 of measuring the vertical width of the mold short side 2b is performed using a plurality of laser sensors 126. The laser beam is irradiated from the light emitting unit of the laser sensor 126 toward the mold short side 2b, and when the laser light is reflected and incident to the light receiving unit, the laser beam is detected and converted into an electrical signal. The microcomputer 136c calculates this and transmits the upper and lower widths of the mold short sides 2b in real time.

In addition, a step 220 of setting the mold short side from the measured width of the mold short side 2b to a vertical state with a vertical taper of 0% according to the set bottom width w1 is performed. The mold width changing motor 5 and the upper and lower mold width changing spindles 6a through a separate mold position control panel (not shown) so that the current measured bottom width value of the mold short side 2b output from 136 matches the set bottom width. 6b), and the upper and lower width measurement values continuously output from the control device 136 are adjusted to match the set lower width w2.

As described above, when the continuously measured upper and lower width measurements are equally adjusted to match the set lower width w2, it can be seen that the mold short sides 2b are accurately positioned in the vertical state with a taper of 0%. It is.

Next, a step 230 of simultaneously adjusting the casting width w3 and the inclination of the mold short side 2b is performed by adjusting the top width w1 of the mold short side and moving it to match the set inclination. This step 230 converts the mold short side 2b to be tapered while gradually reversing only the upper variable spindles 6a, and the detected inclination value of the mold short side 2b measured by the laser sensor 126 is controlled. If the set slope value already input to the apparatus 136 is matched, the casting width w3 and the slope of the mold short side 2b are simultaneously adjusted by stopping the operation of the upper variable spindles 6a.

On the other hand, in Fig. 13 additional steps preceding the method of the present invention are shown with the method of the present invention.

In FIG. 13, when the product design of the product to be cast is determined, the position adjusting step 200 of the laser sensor 126 according to the mold casting width is performed. This step 200 uses the casting width and the slope setting device 100 of the playing mold short side, as shown in FIG. The space bar 122 is selected according to the width of the cast steel to be scattered and seated on the seating posts 129a and 129b, and then the laser sensors 126 are paired to the left and right sides of the seating posts 129a and 129b, respectively. Fix at intervals of up and down.

A step 202 of inputting operation information including the set lower width w2 of the cast steel and the inclination to the control device 136 is performed, which is performed by the control device 136 as the function key 136d of the mold short side 2b. The type and the type of the space bar 122 are selected, and the set bottom width w2 and the slope degree (%) of the mold short side 2b are input.

In addition, a step 204 of verifying the measured value of the laser sensor 126 is performed, in which step 204 is equipped with a zero adjustment bar 147 on the frame 120, and operates the control device 136. The laser beam from the laser sensor 126 to the target portions 147a at both ends of the zero adjustment bar 147, and receive the laser beam reflected therefrom, and the zero point from the laser sensor 126. The width detection accuracy of the laser sensor 126 is detected and checked by comparing whether or not the reference values by the scales up to the target portions 147a of the adjustment bar 147 coincide with each other.

Then, after confirming that an accurate measurement of the laser sensor 126 has been obtained, a step 206 of mounting the laser sensor 126 into the mold 1 is made, which is to stand the stand block 127 of the frame 120. The ball spacer 137 seated on the mold long side 2a, interviewed and supported by the upper edge 1a of the mold long side 2a, and mounted on the front and rear surfaces of the body frame 120 in opposite directions. The built-in ball 133 is elastically in close contact with the mold long side 2a so that the lower part of the main body frame 120 is located in the middle of the width direction between the mold long sides 2a and prevents shaking of the main body frame 120. It is.

When the frame 120 is mounted on the mold long side 2a using the water level 125 and the level adjusting screw hole 127a of the level stand 125a, the level stand 125a. Step 208 is performed such that the laser sensors 126 are positioned horizontally so that the laser beams are mounted horizontally.

In addition, in this state, the steps 210, 220 and 230 of the present invention are performed to set the short side casting width and the slope of the playing mold.

On the other hand, using the present invention, a mold having a multi-tapered short side 2b 'as shown in Figs. 11C and 11D may be used. The mute tapered short side (2b ') is formed on the side facing the cast piece based on the solidified shell shape of the cast, which is a structure for preventing the lower edge of the mold short side (2b') is worn on the cast piece and deformed to be.

This multi-tapered short side 2b 'knows in advance the profile trajectory of the side facing the slab, and adopts the same method as the present invention to simultaneously adjust the casting width and the slope of the mold short side 2b'. .

That is, the upper and lower lateral widths of the multi-tapered mold short sides 2b 'are measured using the plurality of laser sensors 126, respectively, and the lower width of the measured multi-tapered mold short sides 2b' is set to the lower width. The casting width w3 of the mold short side 2b 'by adjusting the displacement of the lower edge along the profile trajectory by reversing the top width of the multi-tapered mold short side 2b' and adjusting the displacement amount of the lower edge in accordance with the profile trajectory. And the slope are adjusted to the desired values at the same time.

As described above, according to the present invention, the upper and lower one-side widths of the mold short sides 2b are accurately measured by the laser sensor 126, and the mold short sides 2b are vertically set to 0% inclination with the set lower width w2. After adjusting to a state, the casting width w3 and the inclination of the mold short side 2b can be adjusted simultaneously by moving the upper end width of the mold short side 2b to approach the set inclination.

Therefore, mold casting width and inclination setting work for casting work is quickly made to increase the productivity, mold casting width measurement work is simply standardized, and the accuracy of data is improved to improve cast quality.
