Description

[0001] Launder for transportation melting metal [

The present invention relates to a ladder for transferring molten metal, and more particularly, to a ladder for transferring molten metal, which prevents the metal from being solidified at the end of the ladder where molten metal is dropped compared to a conventional ladder for transferring molten metal, And more particularly, to a runner for transferring molten metal, which solves distortion of a pipe due to noise, positional fluctuation, and friction caused by the noise.

In processes requiring molten metal, such as melting molten metal for molten plating or molding molten metal into a certain mold, it is necessary to move molten metal. For example, in the hot dip galvanizing process, zinc is melted and molten zinc is transferred to a hot dip galvanizing bath, and a metal necessary for hot dip galvanizing is inserted into the hot dip galvanizing bath. The melting point of zinc is 419.5 degrees Celsius, melted and then moved through Launder, which is thermally expanded due to the high temperature of zinc. The thermal expansion means that the length, area and volume of the object increase as the temperature of the object increases. Therefore, the object placed in the high temperature working environment should be designed considering this thermal expansion. When the ladder is stretched, the rudder for transferring the molten zinc is spaced a certain height from the ground or other structure and is installed on a separate support. When the ladder is stretched, friction with the support and noise due to the position change of the support, There is a problem that twisting of the pipe and composition of anxiety due to friction occur.

In addition, there is a problem in that the molten zinc moves, because the molten zinc moves in the runner or the pipe itself because there is no constitution for heating zinc or a constitution for keeping warm, and a part of molten zinc is solidified. This phenomenon occurs frequently at the end of the runner where the molten zinc falls into the hot dip galvanizing bath, because the molten zinc is in direct contact with the air and the temperature falls below 419.5 degrees Celsius, the boiling point of zinc to be. As regards the hot dip galvanizing process which is one of the operations using the molten metal described above, Korean Patent Laid-Open No. 2011-0054490 ("hot dip galvanizing bath including a sliding lid for thermal loss reduction ", May 25, 2011) Open Publication No. 2014-0130865 ("Hot-dip galvanized steel sheet manufacturing apparatus and hot-dip galvanized steel sheet production monitoring apparatus ", Nov. 12, 2014).

1. Korean Patent Laid-Open No. 2011-0054490 ("Hot-dip galvanizing bath containing sliding-closing lid for heat loss reduction ", 2011.05.25.) 2. Korean Patent Laid-Open No. 2014-0130865 ("Hot-dip galvanized steel sheet manufacturing apparatus and hot-dip galvanized steel sheet production monitoring apparatus ", 2014.11.12.)

Accordingly, it is an object of the present invention to provide a runner for transferring molten metal, which is capable of preventing the occurrence of noise, position fluctuation and friction caused by expansion of a molten metal transferring runner during transfer of molten metal. It is possible to solve the twisting of the pipe and prevent the metal solidification phenomenon occurring at the end of the ladder for molten metal transfer so that the user can more easily adjust the inclination angle of the molten metal transfer liner to control the supply rate of the molten metal, Which is capable of supplying molten metal.

In order to solve the above-described problems, a molten metal transferring runner includes a tilted rudder (100) for flowing molten metal in an inner space, a ground or other structure and a lower portion of the rudder And a heating unit 300 disposed at an end of the lancet 100 at an inclined end thereof. The support unit 200 includes a plurality of supports 200 for supporting the lancer 100.

The heating means 300 is an edge burner 310 provided at an upper end of the runner 100 and injecting a flame toward the lower end of the end of the runner 100 where molten metal falls .

The support part 200 includes a support part 210 provided at the lower part and a roller 220 positioned between the support part 210 and the runner 100.

The lancer 100 may include a depression 110 which is recessed downward to be in contact with the roller 220 or an auxiliary plate 120 on which the depression 110 is formed.

Further, the support base 210 is adjustable in height, and the upper support base 230 and the lower support base 240 can be expanded and contracted.

In addition, the support part 200 includes a sensor for height measurement on the upper side.

According to the present invention, since the heating means for heating the molten metal is provided at the upper end of the pipe, there is an effect of preventing the solidification phenomenon of the molten metal occurring at the end of the pipe and smoothly transferring the molten metal.

In addition, according to the present invention, since the supporting portion to be in contact with the pipe is formed by the roller, noise generated when the pipe is stretched by the heat of the molten metal is not generated.

According to the present invention, since the height of the support portion provided at the lower portion of the pipe can be adjusted, the slope of the pipe can be adjusted, so that the feeding speed of the molten zinc can be adjusted.

Further, according to the present invention, a user can easily adjust the inclination of the molten metal transferring runner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

The molten metal transferring runner 100 according to the present invention includes a runner 100, a support 200, and a heating means 300 as shown in FIG. The lancer 100 is a passage through which the molten metal moves. The support part 200 supports the lancer 100 and is configured for the convenience of the user. The heating device 300 is a structure in which the molten metal is solidified The configuration for blocking the shape will be described including a detailed configuration.

As shown in FIGS. 1 and 2, the lancer 100 is formed to incline to one side so that molten metal provided in the inner space can flow, and includes a depression 110 at a lower portion thereof. The lancer 100 may be a cylindrical loudspeaker 100, but may have a V-shape or a U-shape with an open upper portion so that the heat of the molten metal flowing into the inside may escape to the upper portion in consideration of durability. When the runner 100 has a V-shape, the flow velocity of the fluid flowing therein is increased, so that the molten metal can be transported more effectively. The position and shape of the depression 110 will be described later. A separate flow rate sensor may be provided on the inner side of the runner 100 to measure the velocity of the molten metal flowing through the inside of the runner 100 to provide the flow rate and velocity information of the molten metal to the operator.

The support portion 200 is formed between a plurality of wafers or other structures and a lower portion of the runner 100 to support the runner 100. As shown in FIGS. 1 and 2, the support unit 200 includes a support 210 and a roller 220.

The support base 210 is provided at a lower portion of the support unit 200 and can be adjusted to a separate structure or a ground, and the height of the support base 210 can be adjusted. The height of the supporter 210 is adjustable by controlling the inclination of the lancer 100 to adjust the speed of the molten metal flowing inside the lancer 100. To this end, a motor (not shown) and an upper support 230, which are connected to the motor and move up and down, are provided so that the height of the support 210 is adjustable. A lower lifting structure such as a lower lifting base 240 to which the lifting frame 230 is inserted is additionally provided to allow the user to control the height adjustment. Of course, the support table 210 is not limited to the above configuration, but may alternatively be configured to use a flexible linear motion by a hydraulic cylinder structure. When three or more supporting portions 200 are formed, the degree of the upward and downward movements of the respective supporting portions 200 is changed for adjusting the inclination. When the height of the support part 200 is adjusted, the support parts 200 need to be driven simultaneously. The degree of the flow of the support part 200 varies depending on the position and the inclination to be adjusted.

A height measuring sensor is included in the support part 200 to measure the height of each support part 200 and calculate the inclination. The sensor for height measurement may be a sensor for scanning the bottom surface of the lower portion supported by the support portion 200 by using radio waves or ultrasonic waves and measuring the time of reflection, It is also possible to have a sensor for measuring the degree to which the ascending / descending structure connected to the lifting mechanism is moved. Preferably, the upper and lower supports 230 and 240 are positioned at the uppermost position of the upper support 230 to scan the reflected wave or the ultrasonic wave from the height measurement sensor, A sensor using radio waves or ultrasonic waves should be provided on the inner upper surface of the upper supporter 230 so as to be scanned with radio waves or ultrasonic waves toward the lower side.

The controller 200 is provided with a control unit for separately receiving related information from the sensor for the height measurement, the adjustment and the inclination calculation of the support unit 200, and the control unit can be remotely adjusted by the user using the wireless communication structure.

As shown in FIGS. 1 and 2, the roller 220 is positioned between the support 210 and the loudspeaker 100. As shown in FIGS. 1 and 2, the roller 220 is in contact with the depression 110 formed at a position where the roller 220 is in contact with the lower portion of the runner 100. The roller 220 is in contact with a support plate of a conventional plate shape when the liner 100 is thermally expanded to generate noise, thereby causing stress to the workers. In addition, the roller 220 has a problem in durability against the connected piping equipment, A roller 220 which can be flowed to prevent the rotation of the roller, and a bracket and a wheel hinged to the bracket. In the prior art, a ladder is placed on an upper portion of a T-shaped support having a slightly inclined upper portion, so that the T-shaped support and the lidar rub against each other to generate noise. When the roller 220 is provided, Noise and torsion can be prevented. Since the thermal expansion expands not only in the longitudinal direction in which the runner 100 is extended but also in the other direction such as the direction perpendicular to the longitudinal direction but the most thermal expansion occurs in the longitudinal direction of the runner 100, The rollers 220 are provided in consideration of the thermal expansion in the longitudinal direction.

The depression 110 is formed to restrict the range of movement of the roller 220 and to fix the runner 100. The depression 110 is formed in an area corresponding to the size of the roller 220 before expansion And is formed to be depressed upward from the lower portion of the runner 100. That is, when viewed from the inside of the runner 100, a portion of the inner side lower portion of the runner 100 protrudes. The degree of protrusion of the depression 100 from the inner side to the upper side is such that it is not disturbed by the flow of the molten zinc. In order to ensure the stability of the runner 100, not only the longitudinal direction in which the runner 100 is extended, A plurality may be formed in parallel with the anode 220, but the most preferable maximum number for the diameter of the runner 100 and the smooth flow of molten zinc is two. The depression 110 may be formed directly on the runner 100, but may be formed on the auxiliary plate 120, which is separately padded below the runner 100, as shown in FIGS. When the auxiliary plate 120 is additionally provided, the depressions 110 do not interfere with the flow of molten zinc, so that the roller 220 may be provided in two or more parallel directions. The auxiliary plate 120 is made of the same material as that of the runner 100 so that it expands to the same degree as the thermal expansion of the runner 100. If the auxiliary plate 120 is provided below the runner 100 and the depression 110 is separately formed in the plate, the molten metal flowing inside the runner 100 is not affected and is efficient. 1 to 3 illustrate an auxiliary plate 120 in a state that the auxiliary plate 120 is thermally expanded, that is, a state where molten metal flows in the runner 100. The depression 110 formed in the auxiliary plate 120, The roller 220 is thermally expanded and formed into an arc shape larger than that of the roller 220.

As shown in FIG. 2, since the runner 100 is mounted on the roller 220, when the inclination is adjusted, the roller 220 flows within the range of the depression 110 .

3 is an enlarged view of a position where the depression 110 and the roller 220 are in contact with each other. It can be confirmed that the roller 220 is placed on the left side of the depression 110.

The heating means 300 is provided at an end of the tilted end of the runner 100. 1 and 2, the heating means 300 is provided at an upper end of the lancer 100 and includes an edge burner 300 for spraying a flame toward the lower end of the end of the runner 100, (310). As described above, the edge burner 310 is a method of directly spraying a flame to prevent molten metal from being smoothly transferred due to a metal solidification phenomenon occurring at an inclined end of the runner 100 . As shown in FIGS. 1 and 2, a mounting frame 320, which is a structure for mounting the edge burner 310 to the edge burner 310, is provided. The mounting frame 320 is provided in such a manner that a part of the frame is bent so that the portion where the flame is sprayed by the edge burner 310 can be adjusted and the angle is adjustable. Generally, the temperature of the flame varies depending on the location of the color or flame. However, the melting point of the metal used in industry is more than 1000 degrees Celsius and the zinc of the embodiment is 419.5 degrees Celsius, The edge burner 310 is industrially useful because it is lower in temperature than the flame being ejected. The edge burner 310 does not continuously operate during the transfer of the molten metal, and the molten metal is visually confirmed to be solidified, or the molten metal is melted away from the molten metal through the monitoring device or the flow rate sensor The edge burner 310 can be selectively operated when the amount of metal is different. When the edge burner 310 is continuously operated, there is a possibility that the edge burner 310 may be damaged by the heat of the spark to be sprayed. Therefore, during the operation of the edge burner 310, the mounting frame 320 is rotated, And use it again.

As described above, the molten metal transferring runner 100 according to the present invention having all the above-mentioned configurations prevents the molten metal from solidifying at the end portion of the runner 100 due to the operation of the edge burner 310, And the inclination of the runner 100 is adjusted by adjusting the height of the support table 210 so that the feed rate of the molten metal flowing in the runner 100 can be controlled, The supporting part 200 is formed of the support table 210 and the roller 220 to solve the noise due to the thermal expansion of the louder 100 and the distortion of the pipe due to the positional change and friction, The worker who has the effect is not stressed.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
