Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a layout of continuous casting equipment for continuously casting cast iron, cast aluminum, aluminum, etc.

In recent continuous casting equipment for cast iron, cast iron, aluminum, etc., molds with overlapping upper and lower molds are continuously made using molding fins, and then sent onto a tufted 24-button continuous mold conveyor line. The mold is moved to the pouring section, - the molten metal to be poured is loaded from the melting furnace into a ladle and conveyed to said pouring section, where a skilled worker pours the molten metal into the pool of unfilled mold. The usual method is to pour the appropriate amount of molten metal by tilting the ladle and adjusting the amount.

These working environments are extremely dangerous and bad, with high temperatures and molten metals such as iron and aluminum often scattering. Moreover, as mentioned above, the pouring operation requires a high degree of skill and requires a certain amount of work. For this reason, there was a strong demand for hot water pouring by Kabujin, and various automatic hot water pouring devices were provided. Research and development of automatic pouring equipment itself has progressed dramatically in recent years, but there are still issues regarding the layout of continuous casting equipment that allows these automatic pouring equipment and mold production lines to operate efficiently and perform continuous casting. Research and development were not sufficiently conducted. One of the biggest reasons for this is that in the past, the new automatic S
This is because the most important thing was to make maximum use of existing equipment when introducing equipment and/or molded fins. However, it has become increasingly recognized that it is extremely important to have an optimal casting equipment layout in order to make the most effective use of pouring equipment and molding lines.Therefore, the object of the present invention is to It is an object of the present invention to provide a layout of casting equipment for continuous casting that can fully utilize the functions of a pouring device and a molding line.

First, an example of an automatic pouring device that can be conveniently used in the layout of continuous casting equipment according to the present invention will be described.

-e v The preferred pouring method of the automatic pouring device and the principle structure of the pouring device described herein are described in the applicant's previous application, for example, Japanese Patent Application No. 4
9-78176, Japanese Patent Application No. 49-78177, Japanese Patent Application No. 50-126302, etc., the present invention will be briefly explained in order to facilitate understanding of the present invention.

As shown in FIG. 1, the pouring device includes a ladle 1, a t-th ladle holding device 2 held inside the ladle 1, and a holding bag Ttz.
It is installed on a base 5 and consists of a T-rail 4 for running. The mold 100 is a hot water pool 100C't-
The upper die 100a and the lower die 100k) are attached to a trolley 104 running on an L/-ru 105, and transported to the pouring section where the molten metal is poured. Next, the ladle 1 of the pouring device is tilted and rotated to the closed position at 11, and the bath water in the ladle is poured from the ladle sprue 10 into the pool 100C. At this time, the positional relationship (
1, h) r; is kept constant. In other words, the axis of rotation of the ladle passes through a point Y near the sprue so that the point 101 where the molten metal starts falling from the sprue does not change due to the tilting of the ladle @b-
It is configured to pivot around b'. These will be explained in more detail below.

@2 figures and l! Referring to Figure 3, the principle of ladle 1
To explain the structure and function, the ladle 1 has a groove shape with a radius W and an axis passing through a point Yt- in the vicinity of 10.
When the bath is poured into the mold 100 through the sprue with an inclination around b-b', the g-out surface horizontal 8 of the residual bath in the drawer I11 is the slope of the drawer -1. #4 is formed in a shape that remains approximately constant regardless of rotation. In other words, it passes vertically through the ladle sprue 10 to the ladle 1! ! As shown in FIG. 3, the 1'r surface shape includes a front wall 8 included at a point Y1 on the ladle rotation axis bb', and a radius R1 from the point Y of this front wall 8.
The arc a-a"j- is shaped perpendicularly to the inner wall surface l1i9, and the whole is formed into a fan-shaped box shape. In particular, the side walls 6.7 are not limited to the shape shown in the figure. , any shape may be used as long as it is symmetrical with respect to the sprue 10. On the inside of the front wall 8, a semicircular convex portion 8' with an axis of rotation b-b' (base point Y) and an edge radius R is provided. , as will be explained later, serves to keep the surface level of the molten metal constant in the ladle.Furthermore, the sprue 10 is provided by forming a groove having a width W in the front wall 8 and the convex portion 81. , the part forming the lower horizontal plane Hi of the virtual flow bath when the bath water at the bottom of the sprue 10 is discharged is formed into an arc shape with a radius R1 from the base point Y. In this ladle, the thickness of the front wall is 2 It will be formed at R1.

The inner wall 12 of the ladle 1 is made of heat-resistant furnace material, and the outer wall 1 surrounding the On! S11 is formed by bath-welding an iron plate.

When the ladle 1 formed as described above is moved by VCC around the rotating shaft @b-b1, the bath water flows out into the mold 100 through the sprue 10 formed in the front wall 8. For this state sound: If we closely observe it, we can see that the w1
In the first rotation, L is positioned above the hypothetical outflowing molten metal lower horizontal plane H by an amount of outflowing molten metal V shown by diagonal lines, and this amount of molten metal flows out from the sprue due to the action of gravity. This hypothetical flowing molten metal lower horizontal plane ■ is located at a position R1 above the rotation axis @b-b', and the bottom of the sprue 1o created by this lower horizontal plane Ht- is in the shape of an arc of R1. The position of the lower horizontal plane H of the molten metal does not change.

In other words, assuming that the point 101 at which the outflowing molten metal V starts to fall into the pool 100c is completely imaginary, this falling starting point 10° always maintains a constant degree t regardless of the rotation of the ladle 1. Therefore, if the outflow bath 1jk is indicated by the hatched area and the outflow bath 1#v is kept completely constant, the molten metal flow will follow a trajectory that is quite constant. That is, f# hot water fall starting point 101 and hot water pool 1
Molten metal is poured while keeping the positional relationship (1, h) with respect to 00c constant.

Furthermore, according to the structure of the ladle 1 described here, the exposed surface species S of the bath water in the ladle is always constant.

In other words, in Fig. 2, the large area gs and the small sprue area S.

The sum of the bath $11 and the outlet surface area S is the small area area of the sprue 8.
, Tsuu Nabe. Rotation, yo, wazuyuyu fluctuation a, ya, a too.
1. Since it is extremely small compared to the large side part S, and can be ignored, and the large side part S is always constant, it can be said that the exposed surface of the molten metal S is always kept constant. Therefore, by rotating the tray 91 according to this embodiment at a constant inclined rotation speed, the flow tf! The melt lhv is always constant, and it becomes possible to pour the metal while always drawing a constant flow @T.

At the outer end of the #A side wall 6.7 there is a rotation axis that passes through the Y point @

The lower frame 20 is attached to the upper frame 18 by being suspended from the upper frame 18 via load cells at four locations on the upper part as described fc. The load f'L is used to send a signal to the control device of the pouring device to fully control the rotation and stopping of the ladle and to control the amount of poured metal. The lower frame 20 has a short letter M24.25 at the front end, and the bearings 13.14 of the ladle 1 are engaged to support the ladle 1 in a rotatable manner. Further, a drive shaft 26 is rotatably provided at the rear end of the lower frame 20, and the drive shaft 26 has a hook gear 27. which meshes with a rack gear 15.16 provided on the tray #41.

The ladle forward tilt stop switch SW3 is used to prevent the ladle from tilting forward excessively when, for example, draining all the bath water in the ladle. belongs to.

Next, the operation of the pouring device will be explained. The ladle 1 transfers its bearing 13.14 to the short cap 24.25 of the ladle holding device 2, and the rack gear 15.16 of the ladle 1 to the ladle holding device 1. A drive gear, B, provided on the lower frame 20.

27, 28 and held in the ladle holding device 2 in a horizontal position as shown in FIG. In this state, the molten metal is transferred from the melting furnace (induction furnace or holding furnace) or the self-propelled molten metal transfer device to the ladle 1), and the ladle, that is, the pouring device t, is ready for pouring. On the other hand, the mold 100 is transferred to the pouring section where the pouring device is located and stopped. At this time, the relationship between the mold pool and the ladle held by the pouring device 2 is set as described above. Note that the layout of casting equipment that is effective to which the pouring device described herein is applied will be described further later.

First, the ladle 1 is tilted and rotated by the driving force M and the speed control mechanism g30 at an initial inclination fIIJ and an angle vu.

The bath water in the ladle 1 begins to pass through the sprue and falls at the starting point 10"
When it starts flowing through one point X (3rd ■) of the i-way distribution line T,
7 tons were installed on the base frame 17 of the ladle holding device 2, and the molten metal outflow simulator 503 completely detected that the hot water was flowing out.
Ladle 1t - Pouring of hot water #Liu The speed is reduced to Vθ2 (ve2 (ve1).Here, the penal bath water outflow ejector 606 is for detecting the mm of hot water flowing from the spout 1o, for example, the heat emitted from the hot water. It also has the function of detecting light (visible light, unexpected light, infrared light), etc. Also, the initial tilting speed θ1 of the ladle 1 is, for example, 10 to 80 times the pouring tilting speed Vθ2. The reason for increasing the speed is to prevent the molten metal from dripping from the sprue when it begins to pass through the sprue.
By making one series, the fixed molten metal pouring tilting speed Vθ2 allows the molten metal to be located above the lower horizontal plane H in the ladle during the pouring process, and to reach the flowing bath water V more quickly, resulting in a predetermined molten metal discharge flow @ This is to get closer to T faster.

When a certain amount of hot water is poured into the mold, a signal is emitted in a manner that will be explained in detail below, and the process begins.
The control device operates and the ladle is tilted backward at a high speed V05 on the backward tilting shaft side. After a certain period of operation, the ladle stops and prepares for the next pouring. Backward tilt iI! In order to prevent the bath water from dripping from the sprue, pouring =
It is preferable that the S speed is approximately equal to or larger than the magnitude of the S speed v82. Inclination of the ladle vJ speed reaction ve in the above explanation
, 1, ve, 2 and '7. s varies depending on the capacity of the ladle, the viscosity caused by the material and temperature of the hot water, the positional relationship (1, h) between the ladle sprue and the mold pool, etc., and is appropriate! & It is set so that the amount is small.

In a pouring device, a method and device for automatically measuring molten metal for pouring a fixed amount of molten metal in a ladle into a mold will be described in detail.

First, the configuration of the automatic weighing device will be explained. The automatic weighing device is as schematically shown in Figure @6. That is, as described above, the load cells, that is, the load electrical converters 19a, 19b, 19c, and 19d provided in the ladle holding device 2
is provided, and the output of the load electrical converter is connected to an adder 20.
1, the output of the adder 201 is connected to the adder 203 through the amplifier 202, and the other input 206b of the adder 203 is connected to the total amount of molten metal to be poured into one mold. A pouring amount setting device 204 to be set is connected. Additionally, the adder 20' has an addition control input 2060, and the pouring amount is set @204 only when a signal is added to the addition control input.
It is configured to add the signals from . The output of the adder 203 is converted into an analog quantity to digital quantity converter (
(hereinafter referred to as an LD converter) 205, and its output (disitalic acid) is #! 206.

The memory circuit 206 has a control human power 206b, and is configured to store the digital value at of the human power 206a only when a signal is applied to the control human power 206b.

The output of the memory circuit 206 is rape 2a70 standard human power 2o7

The output of the H-D converter 205 is connected thereto. The comparator 207 is configured to issue an output signal when the digital force applied to the comparison force 207b is equal to or smaller than the digital force of the reference input 207a.

Next, the operation of the automatic #it device will be explained. First of all, to explain the 191 work in which the pouring device starts pouring, the load and the load are placed on the ladle 1, the lower frame 20 that supports the ladle, and the base provided on the lower frame 20. Loads of various members and the molten metal in the cutting ladle are added, which is converted into a dL multiplication signal T and appears in the output of the adder 201. However, the output of the load electrical converters 19.about.191C is increased because its electrical allowance is small and unsuitable for control! The signal is amplified by the amplifier 202.

At this time, the addition control input 203C of the adder 203 is configured in such a way that no signal is applied, and the output of the amplifier 202 appears as it is in the output of the adder 203.

After initial value W is fully memorized, pouring amount # is pouring operation t''
First, the ladle is tilted. At this time, a signal is added to the addition control human power 206C of the adder 203, which is added to the molten metal pouring amount setting device (setting 1 straight 7 W3) of the molten metal pouring amount setting device 204 and the power bow calculator 203. 1'D converter 205

becomes. That is, the values of the comparator 2070-based Hayabusa power 207a and the comparison power 207b become the same, and the comparator 207 operates,
Generates a quantitative signal at the output. As a result, the ladle stops recessing forward and tilts back, completing pouring into the mold.

, Since the pouring bath water amount automatic meter device f is constructed and works as described above, it can be used for stacking ladle, stacking frame, and when attached to the frame, stacking next piece of wood, etc. It is possible to accurately pour a set number of molten metals without being affected at all.

Also, as per the above explanation, #imin11! Since @# is performed based on the relative value of L, the absolute accuracy of each component of the measuring thread, such as the load voltage converter, multiplier, adder, k-reverse converter, etc., does not affect the operation of the metal.

becomes simpler and the stability is the same as above.

In addition, if there is a large error in the observed value of the vibration caused by the operation of the pouring device, etc., the output value of the &-D converter 205 is averaged several times to avoid confusion. It is stored in the memory circuit, and the comparator 2
07 operates several times, that is, when the comparative human power matches or becomes smaller than the reference input several times, it is configured to issue a stationary signal to reduce errors caused by vibration.

One embodiment of the equipment layout will be described with reference to 17eW.

The casting equipment line is a molding line that continuously makes molds and transports the molds to a predetermined pouring position.

, the holding furnace 51) to the molten metal pouring device at the molten pouring position. In this example, there are two molding lines L (MLl, 1tL2).
provided. A pouring line is provided parallel to the molding line ML1, and therefore runs parallel to the molding line in Note'c# fPa. For the molding line/MI+2, two lines of pouring lines (PL2, PI, 5) are provided in parallel between the molding line ML2 and the squares. Of course, the number and arrangement of molding lines and pouring lines are C.
The present invention is not limited to this, and various other embodiments may be adopted.

First, to explain the pouring aS by the molding line MLi and the pouring line PL1, all of the bath water is transferred from the holding furnace 51, the nine bath water conveying device 1t52 runs on the molten metal conveying line,
The bath water is transferred to the ladle of the pouring device Pa at one point. At the same time as the transfer is completed, the molten metal transfer device 52 returns to the standby point S3. After the transfer is completed, the molding line ML1 moves, and when the unfilled mold reaches the 21st point, the unfilled mold frame detector 302 installed in the pouring device issues a signal indicating that molten metal should be poured, and the pouring device [ starts automatic pouring operation. The ladle is tilted forward at a high speed Vθ1, and when the hot water in the ladle starts to fall, the molten metal outflow detection a'503 is activated and generates a signal, and the ladle 1 is rapidly decelerated to the tilting speed Vθ2. Then pour the metal into the mold. When the automatic pouring bath molten metal meter is poured for a set number of minutes, the ladle starts tilting backwards at high speed Vθ, and stops after tilting at a certain angle. , ends the first note IIf with 21 points. In response to the molten metal pouring completion signal, the mold is moved by arrow X million times in 1 takt, and the unpoured mold is moved from the 22nd point to the 21st point. The mold stops and pouring is performed at 21 points as before, and the second pouring at point PI is completed. note*? P: After finishing, this time there will be 2 spas
Move from point 1 to point 22 in the direction of arrow Y and stop. While the pouring device Pa is moving, the mold remains stopped. After the pouring device Pa stops, it pours the unfilled mold in the same manner as the previous time, and the pouring device # performs the first pouring at 22 points.

The above cycle is continued one after another, and when the remaining hot water in the ladle becomes less than the specified value, the remaining hot water is activated by the operation of the remaining hot water drain switch SW.
k is intentionally stopped, and the pouring device at point Pn returns to running on its own axis at point 21.

Then, the molten metal is supplied again from the bath water conveying device It, 52. Note #h@f11. Repeat. Stopping the molding line,
Or, when disposing of the remaining hot water in the pouring device after the pouring f'F-chestnut ends, set the pouring device 1P11' to PO position! The molten metal is moved to point t, and the molten metal is transferred from the molten metal pouring device al to the molten metal transfer device 521 by calling in the molten metal transfer device [52' of the bank] to point 20. After this work, bath water gi feeding tray 52m waiting point S

The molding line [112 is 1% continuous, and the pouring lines are arranged at fixed points on the molding line in the direction perpendicular to the molding line, in this example two rows, and the pouring lines (PL2, FL
Y) is provided with pouring devices Pb and Pc, respectively. The ladle of the pouring device fJiPb is transported to the bath water ftglI from the molten metal transfer device 52 at point Q. The molten metal transfer device 52 automatically returns to the standby point S3 at the same time as the transfer is completed.

After the transfer is completed, the molding line ML2 moves, and when the unfilled mold reaches point Q, the unfilled mold is activated and the pouring device automatically pours the molten metal. Start creating Ih1it+. The tray is tilted forward at high speed VO2, and when the molten metal starts to fall from the sprue of the tray, the molten metal outflow detector 303 moves t'll-.
The ladle is rapidly decelerated to the initial velocity Vθ2 of pouring #i, and when the automatic bath water filter device is dispensed at the setting of 9 in the previous morning, it starts high-speed tilting, stops after tilting at a certain angle, and pours the ladle. End the cycle. Upon receiving the pouring completion signal, the mold moves ri1 tact,
Hechutouyu reaches point Q. After stopping the mold, I poured the metal at point Q, which was the same as before. While the pouring device mpb is sequentially pouring, V molten metal is supplied to the pouring device PC'' at point R by the molten metal conveying device 52. The pouring progresses in the pouring device Pb. The remaining hot water in the ladle is below the specified amount (see Figure 7).
In the case of the embodiment shown in FIG. 2, when the molten metal can be poured twice (Fi), the molten metal pouring device Pc starts pouring the molten metal. After the pouring device fire starts pouring and finishes pouring twice, the pouring device 1jPb

Next, move the molten metal conveying device to point R, and # Transfer the remaining hot water of Pc. The automatic return button automatically returns the bath water transfer device to the standby point.

゛ An example of the actual specifications of the casting equipment described above can be as follows. 1
1. Mold frame transfer for molding line MI+1: 60 sec Tact mold frame movement time: 10 sec Molten pouring device movement time: 12 sec 1. Mold flask movement for molding line ML2: 24 sec Tact mold movement time: 7 sec Maximum Pouring II near 0ky/required pouring time for mold + 15 sec (70ky/molded layer) In the description of the casting equipment, the pouring frame detector 302 and the molten metal overflow ejector 301 will also be briefly described. As clearly shown in FIG. 4, both of these detectors are installed on the side of the upper frame 18 of the pouring device, and the unfilled molten metal frame detector 302 detects a 100 cK bath in the mold pool. Detects whether or not there is hot water Note 1i! This is to fully control the start of operation of the device, and molten metal overflow detection number 70 - detection number 301 is to make the operation of the pouring device safer. This is greater than the drawing safety ri of the dynamic pouring device.

The molten metal overflow detector 301 will be explained in more detail with reference to FIGS. 8 and 9. The mold 100 has a molten metal 100e that communicates with the upper end of the hot water pool 100c.
is further provided. The molten metal is 100 times hotter than the ladle 1.
The injected melt #j is temporarily stored in a molten metal pool and is injected into the mold through the sprue 100d4. At this time, when the bath water is poured from the ladle 1 (@include 1i), the surface s1 of the bath water in the hot water pool 100c is 0-0@, that is, the melt that communicates with the hot water pool 100c? #Bottom D of taxiway 1ooe
I]+3. It is injected so that it is located below the area.

In other words, the molten metal is adjusted to prevent the molten metal from overflowing from the pool 100c and flowing into the guiding path 100e during normal casting. When the mold volume is sufficiently filled with the bath, the flow of bath water from the pool 100c through the sprue 100d is stopped, the bath is rolled up into the pool, and finally crosses the a-a line t- to the guideway 100e. No. 10,000 handed over
The Rukoto.

A molten metal overflow detector 301 is provided above the guideway 100e to fit a part of the guideway 100e, which detects when the molten metal flows out into the guideway 100e. When 301 is activated, pouring of molten metal from ladle 1 into tundish pool 100d- is stopped. In the water embodiment, the molten metal overflow detector 301
is provided diagonally above the molten metal pool 100C of the molten metal guiding path 100e (see FIG. 4), but is not limited to this and may be provided at other locations.

When pouring hot water into the mold from the ladle 1, the bath water should be placed in the sun or at the hot water level 8. However, in order to prevent this scattered bath water from leaking into the bath water overflow detector 301,
The molten metal guiding path can be made slightly longer, and the cutout wall Ii [1200a I
It can also be used to prevent IC chips from scattering. In addition, when using a bath water overflow detector to detect overflow from the bath pool, and then tilting the drawer at full speed backwards to stop pouring, the molten metal flow from the ladle pouring spout to the mold Pools and guideways must be designed to accommodate hot water.

If you use the above tap pouring amount control method, if a defect occurs inside the mold, the molten metal will immediately overflow into the molten metal guide path, so it will be detected immediately and the pouring will be stopped. It has the advantage of obtaining

In the above explanation, the pouring device was configured to run on rails 4 laid on the ground, but of course, as shown in FIG. #I may be made.

In that case, there is no need for the stile, the rails 4 on the ground, the wheels of the pouring device, and their driving strings, and instead there are rails installed on the ceiling, wheels and other devices for running on the ceiling side so that the rails can run at a constant rate. A friend traveling device (kawamizuzu) will be installed to cover the snow.
