Description

Exit Control Center Control Unit {CONTROL DEVICE FOR CENTER OF FURNACE HOLE}

The present invention relates to an outlet center management apparatus, and more specifically, an outlet center management apparatus for guiding a hole to form a hole in the center of the outlet when opening the outlet to discharge the melt from the inside of the furnace. It is about.

Generally, iron ore and coke are charged in the blast furnace, and hot hot air sent from the hot blast furnace equipment is introduced into the blast furnace to produce iron water by melting iron ore.

The molten water dissolved in the blast furnace is discharged to the outside of the open exit port because the exit port is opened by the air hole.

When the exit opening is opened while the center of the opening is not aligned, the expansion of the exit opening occurs due to one-sided wear and the like during discharge of the water, and a poor discharge of the water occurs.

In addition, when the mud gun nozzle tip for blocking the exit port is moved to the exit port, the exit hole that is not centered is not blocked by the mud supplied through the mud gun nozzle tip, which causes the exit port defect. .

In order to guide the open hole to the center of the exit port, two workers install the round bar in an X shape at the time of the exit port penetration operation, and the excavation bit of the open hole is supported by the round bar provided in the X shape.

The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

When opening the center of the exit port, two workers directly hold the round bar and guide the work of the opening machine, thus the workforce is wasted.The open bar is shaken during the opening work, so the hole is formed in the part separated from the center of the exit port. It may cause a defect. In addition, since the worker is standing next to the large hot water flowing water, the risk of a safety accident increases due to high heat and a large amount of dust. Therefore, there is a need for improvement.

The present invention has been created by the necessity as described above, because the two workers holding the round bar to stand next to Daetangdo to guide the opening of the open air, the workforce is wasted and the risk of safety accidents increased and the central processing of To prevent deterioration of accuracy The purpose is to provide a port-oriented management system.

The outlet center center management apparatus according to the present invention includes: a frame member disposed in the blast furnace outlet center and a centering hole member which is provided in the frame member to which an opening is formed to center the blast furnace outlet center.

In addition, the centering hole member may include a first centering hole member having a first centering hole part into which openings are inserted, and a second centering hole member having a second centering hole part disposed to be spaced apart from the first centering hole part to insert openings therein. It is preferable to include.

In addition, the centering hole member is preferably formed to extend in the advancing direction of the opening machine to include a support for supporting the opening machine.

In addition, the present invention, it is preferable to further include a rotating member which is provided rotatably and the frame member is installed.

In the opening center opening management device according to the present invention, since the central management of the opening machine is made through the centering hole member provided in the frame member when opening the opening port, a separate work force is not required, thereby preventing waste of working manpower. The risk of a safety accident can be reduced, and the center processing of the opening machine is guided through the fixed centering hole member, so that the accuracy of the center processing can be improved.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the outlet center management apparatus according to the present invention. For convenience of explanation, a description will be given using an exit center management device used at the exit of the blast furnace as an example.

As shown in Figures 1 to 4, the outlet center management apparatus 1 according to an embodiment of the present invention, the frame member 20 and the frame member is disposed spaced apart from the center of the blast furnace outlet 10 ( The centering hole member 30 is inserted into the opening hole 14 for centering the center of the blast furnace outlet 10 is provided in 20).

On the lower side of the blast furnace where the molten water is produced, a tap hole 10 for pulling the molten water outward is provided on the blast furnace wall 12.

The lower side of the tap opening 10 is provided with a large hot water guide to guide the molten water from the tap opening 10 to the outside.

The opening machine 14 used to open the exit port 10 includes a motor member 18 for supplying rotational power, and an excavation bit 16 that is axially connected to the motor member 18 to rotate. One end of the excavation bit 16 is provided with a cutter for opening the tap opening 10.

The frame member 20 may be installed in a fixed state on the blast furnace wall 12 or may be installed in a rotatable state.

The frame member 20 may be formed in various shapes within a technical concept for separating the centering hole member 30 from the blast furnace wall surface 12 in a state in which the frame member 20 is spaced apart from the center of the blast furnace outlet 10.

Frame member 20 according to an embodiment of the support bar 22 is formed extending outwardly from the blast furnace wall 12, the extension bar 24 and the frame member 20 extending downward from the support bar 22 It comprises a handle member 26 that can be gripped by the worker to move the).

The centering hole member 30 provided below the frame member 20 may include a first centering hole member 32 and a first centering hole part 32 having a first centering hole part 33 into which the opening 14 is inserted. 33 and a second centering hole member 35 having a second centering hole part 36 into which the opening 14 is inserted.

The first centering hole member 32 and the first centering hole member 32 and the excavation bit 16 passing through the second centering hole member 35 can be moved toward the center of the outlet 10. 2 The installation angle and the position of the centering hole member 35 is manufactured in a set state.

As shown in FIG. 4, according to another embodiment of the present invention, the centering hole member 30 is formed to extend in the advancing direction of the opening 14 to support the support 39 for supporting the opening 14. Include.

The support 39 is formed in a cylindrical shape, and the support 39 is manufactured with the installation angle and position set such that the excavation bit 16 passing through the support 39 is moved toward the center of the outlet 10. .

When the frame member 20 is installed in a rotatable state with respect to the blast furnace wall 12, the rotator wall 12 is provided with a rotating member 40.

The rotating member 40 may be formed in various shapes within the technical concept in which the frame member 20 is rotatably installed.

Rotating member 40 according to an embodiment includes a connecting portion 48 fixed to the blast furnace wall 12, and a receiving bar 44 hinged to the connecting portion 48.
