Description

[0001] The present invention relates to an object treatment apparatus,

More particularly, the present invention relates to an object-to-be-treated apparatus capable of improving the life of a shell having an inner space through which the object can be processed.

Generally, blast furnace operation is a process of charging iron ore and coke to the upper part of a blast furnace, a process of burning coke by blowing hot wind with a tug formed in the blast furnace, a process of removing impurities and oxygen of iron ores by the heat and gas generated by burning coke, . ≪ / RTI > The molten iron in the liquid state is stored in the lower part of the blast furnace, and is discharged through the outlet after a lapse of a predetermined time.

A stave is installed on the inner side of the iron pipe forming the outer shape of the blast furnace. The stave is formed with a path through which the cooling water moves within the stator in order to protect the scraps from the heat generated in the blast furnace. Therefore, it is possible to prevent the cooling water, which moves inside the stave, from cooling the wick to be thermally deformed.

As the use time of the blast furnace increases, the stab may wear due to the thermal load or the friction due to the falling of the charge in the blast furnace. Conventionally, a refractory is installed on the front surface of the stave to protect the stave. However, since the refractories are cracked or worn out at the end of the life of the blast furnace, they all disappear and the refractory does not protect the stables for a long time.

To illustrate the invention in detail, the drawings may be exaggerated and the same reference numbers refer to the same elements in the figures.

Fig. 1 is a view showing the structure of an object to be processed according to an embodiment of the present invention. The embodiments of the present invention exemplify the blast furnace, but the present invention is not limited thereto, and the application range is not limited thereto, and can be applied to various facilities for treating the object to be treated at a high temperature.

Referring to FIG. 1, an object to be processed 100 according to an embodiment of the present invention includes a body having an inner space into which an object to be processed can be charged, a body member 110 provided inside the outer body, And a protruding member 130 formed on one side of the body member 110 so as to protrude from the surface of the body member 110. At this time, the object to be treated 100 may be a blast furnace, the object to be treated may include iron ore and coke, and the shell may be a crust 160 of blast furnace.

The blast furnace is a facility for continuously producing molten iron using iron ore and coke. The blast furnace can be formed in the form of a container having an open top and an internal space. The outer shape of the blast furnace is made of a wicker (160). That is, the iron foil 160 may be formed in a container shape. When iron ore, coke, etc. are charged together with the open top of the furnace and hot air is blown and heated to about 1500 ° C, the molten iron or slag can be stored in the lower part of the inner space of the blast furnace.

A tuyere (not shown) may be formed at the bottom of the blast furnace. The tuyere can be connected to a hot air supply line (not shown), and hot air supplied from the hot air supply line can blow hot air into the inside of the blast furnace. A plurality of tuyeres may be disposed radially along the perimeter of the blast furnace.

The hot air supply line may include a cyclic pipe surrounding the perimeter of the blast furnace so as to uniformly supply the hot air supplied from the hot air path (not shown) to the inner space of the blast furnace, and a blower tube branching to each tug in the annular pipe. Therefore, hot air supplied from the hot air path can be uniformly introduced into the blast furnace through a plurality of tongues.

An outlet (not shown) may be formed in the lower part of the blast furnace to allow the heating wire to exit. The outlet is located below the tuyere. A plurality of outlets may be provided. For example, four outlets may be provided and arranged respectively in four directions along the circumference of the blast furnace. The outlet is openable and closable. Thus, when the exit port is blocked, the charred wire can be maintained in the blast furnace, and when the outlet is opened, the charred wire stored in the blast furnace can be taken out. However, the number of the outlets and the structure of the blast furnace are not limited to this and may vary.

At this time, the body member 110, the protruding member 130, and the refractory member 120 may be installed inside the crust 160 to protect the crust 160 forming the outer shape of the blast furnace from the heat inside the blast furnace. Therefore, it is possible to prevent the convex hull 160 from being thermally deformed.

FIG. 2 is a perspective view showing a structure in which a body member, a protruding member and a refractory member according to an embodiment of the present invention are installed in a container, FIG. 3 is an exploded perspective view showing a structure of a body member and a protruding member according to an embodiment of the present invention FIG. 4 is a view showing the shape of the protrusion according to the embodiment of the present invention, and FIG. 5 is a view showing the structure of the protrusion according to another embodiment of the present invention.

2 and 3, the object to be processed 100 according to the embodiment of the present invention includes an outer shell 160, a body member 110, and a projecting member 130, A first cooling fluid line 140 installed on the body member 110 to cool the body member 110 and a first cooling fluid line 140 installed on the body member 110 to cool the protrusion member 130 And a second cooling fluid line 150 installed in the protruding member 130 to cool the cooling fluid. The longitudinal direction L of the body member 110 is the up and down direction and the width direction W of the body member 110 is the left and right direction and the thickness direction T of the body member 110 is the front- have.

The body member 110 may be formed in a rectangular plate shape. The body member 110 has an area in the longitudinal direction and a width direction, and may have a thickness in the thickness direction. A plurality of body members 110 may be disposed to surround the ridges 160 inside the ridges 160. The body member 110 may be disposed parallel to the skin 160. That is, the plurality of body members 110 are also arranged in the transverse direction and also in the longitudinal direction. The body members 110 may be spaced apart from one another. At this time, the body members 110 may be staggered in the vertical direction.

An insertion groove 111 may be formed on one surface of the body member 110 (or a surface facing the interior of the blast-furnace) to allow the protruding member 130 to be inserted therein. The insertion groove 111 may be formed along the shape of the protruding member 130.

In addition, an installation groove 112 in which the refractory member 120 can be installed may be formed on one side of the body member 110. The mounting grooves 112 may extend in the thickness direction, and may have a plurality of mounting grooves 112 spaced apart from each other in the longitudinal direction. Accordingly, the area of contact between the body member 110 and the refractory member 120 increases, and the refractory member 120 can be stably fixed to the body member 110. However, the structure and shape of the body member 110 and the structure in which the plurality of body members 110 are disposed are not limited to the above and may vary.

The body member 110 may be spaced apart from the crumb 160 and a space between the body member 110 and the crumb 160 may be filled with a back filling material (not shown), which is a refractory material. The main component of the back filler is alumina, which is different from the castable which is mainly composed of SiC. Thus, the iron sheet 160 can be doubly protected from the heat inside the blast furnace by the body member 110 and the back filling material.

The refractory member 120 may be a refractory provided on one surface of the body member 110. The refractory member 120 can protect the body member 110 from the heat and the charge inside the blast furnace. For example, the refractory member 120 may include at least one of a first refractory 121 formed in a brick shape, and a second refractory 122 an irregular refractory.

The first refractory 121 may be a regular refractory formed into a brick shape. The first refractory 121 may be provided in a plurality of mounting recesses 112 formed in the body member 110. One side of the first refractory 121 may be inserted into the installation groove 112 and the other side of the first refractory 121 may protrude to the outside of the first refractory 121. Accordingly, a plurality of grooves formed by the first refractory 121 protruding from one surface of the body member 110 can be formed. The first refractory 121 may have a through hole 121a through which the protrusion 132 can be positioned.

The second refractory 122 may be a castellum that is installed on one surface of the body member 110 on which the first refractory 121 is formed. The second refractory 122 may cover one side of the body member 110 and the first refractory 121. The area of the second refractory 122 contacting the body member 110 and the first refractory 121 may be increased by the first refractory 121 protruding from the body member 110. [ Accordingly, the second refractory 122 can be stably fixed to one surface of the body member 110. However, the structure of the refractory member 120 is not limited thereto and may vary.

Referring to FIG. 1, the first cooling fluid line 140 forms a path through which the cooling fluid moves, and serves to cool the body member 110. The first cooling fluid line 140 may support the body member 110. The first cooling fluid line 140 includes a first supply pipe 141 forming a path through which the cooling fluid moves, a first control valve 142 installed in the first supply pipe 141, A first moving pipe 143 having one end connected to the first supply pipe 141 and a first outlet pipe 144 connected to the other end of the first moving pipe 143. At this time, the cooling fluid may be cooling water. However, the type of cooling fluid is not limited to this and may vary.

The first supply pipe 141 is formed in the shape of a circular pipe to form a path through which the cooling fluid moves inside. The first supply pipe 141 is disposed outside the blast furnace and is connected to a tank (not shown) in which the cooling fluid is stored, and supplies the cooling fluid supplied from the tank to the first moving pipe 143. At this time, the first supply pipe 141 may be connected to the first moving pipe 143 installed inside the body member 110 through the pipe 160 and the body member 110.

The first control valve 142 is provided in the first supply pipe 141 and serves to open and close the path of the cooling fluid formed by the first supply pipe 141. When the first control valve 142 is opened, the cooling fluid stored in the tank can be supplied to the first moving pipe 143 through the first supply pipe 141. When the first control valve 142 is closed, The fluid may not be supplied to the first moving pipe 143.

The first moving pipe 143 is installed inside the body member 110, and forms a flow path through which the cooling fluid moves. The first moving pipe 143 may be a circular pipe, and one end thereof is connected to the first supply pipe 141. Since the first moving pipe 143 can move the cooling fluid supplied from the first supply pipe 141 inside the body member 110, the cooling fluid, which moves inside the first moving pipe 143, (110) can be cooled. Therefore, the cooling body member 110 can protect the ridges 160 from heat inside the blast furnace, and the temperature of the ridges 160 can also be lowered.

The first discharge pipe 144 may be formed in a circular pipe shape to form a path through which the cooling fluid moves. The first discharge pipe 144 may be connected to the other end of the first moving pipe 143 through the pipe 160 and the body member 110. Accordingly, the cooling fluid moving inside the first moving pipe 143 can be discharged to the outside of the first moving pipe 143 through the first discharge pipe 144. However, the structure and shape of the first supply pipe 141, the first moving pipe 143, and the first discharge pipe 144 are not limited to these, and may vary.

However, in order to protect the body member 110, the refractory member 120 installed on one surface of the body member 110 may be extinguished at the end of the blast furnace life. That is, the refractory member 120 may be destroyed by collision with the charge in the blast furnace, or by the occurrence of a crack in the first refractory 121. Thus, there is a problem that the refractory member 120 can not protect the body member 110 for a long time. Accordingly, the protruding member 130 is provided to protect the body member 110 even after the refractory member 120 is destroyed.

2 and 3, the protruding members 130 are provided as many as the number of the body members 110, and are connected to the body members 110 to protect the body members 110. Referring to FIGS. The protruding member 130 may be formed of a material having a high wear resistance, and may have better abrasion resistance than the body member 110 or the refractory member 120. Therefore, it is possible to suppress or prevent the abrasion or breakage of the projecting member 130 even when colliding with the blast furnace charge. For example, the protruding member 130 may be made of steel or ceramic. However, the material of the protruding member 130 is not limited to this and may be various.

The protruding member 130 has a connecting portion 131 that can be fitted into the insertion groove 111 and a connecting portion 131 having one side connected to the connecting portion 131 and the other side projecting toward the inside of the blast furnace of the body member 110 And includes a protrusion 132. The protruding member 130 may extend in the width direction of the body member 110 and may have a length in the width direction even if at least a portion thereof is bent or curved. Thus, the charge or deposit may be deposited on the protruding member 130.

The connection portion 131 is inserted into the insertion groove 111 and can be detachably connected to the body member 110. The connection portion 131 may be supported by the body member 110 and may support the protrusion 132.

The protrusion 132 may be formed in a plate shape and connected to the connection portion 131 and may protrude toward the inside of the blind hole of the body member 110. The protrusion 132 may extend in a direction intersecting the extending direction of the body member 110. The projecting portion 132 may be integrally formed with the connection portion 131.

The projecting portion 132 can be formed such that the positions of the both end portions A are higher than the position of the center portion B with respect to the bottom of the blast furnace. That is, the extending direction of the protruding portion 132 may be formed by connecting a plurality of plates extending in the oblique direction to the width direction. Thus, deposits may build up or form on the upper surface of the protrusions 132 to form an adhesive layer. Therefore, even if the refractory member 120 is destroyed, the adhesion layer on the protrusion 132 covers the body member 110 to protect the body member 110.

As shown in Fig. 4, at least a portion of the protrusion 132 may have curvature or be refracted. For example, the protrusion 132 may be formed in various shapes such as a V shape, a U shape, and a W shape. Thus, the deposit deposited on the upper surface of the protrusion 132 or the generated deposit can be stably received in the protrusion 132, and it is possible to suppress or prevent the deposit from falling out of the protrusion 132.

5, at least one of the protrusions 132a and the protrusions 132b may be formed on at least one surface of the protrusion 132. In addition, For example, the protrusion 132a and the protrusion 132b may be formed on the upper surface of the protrusion 132. [ Accordingly, the area of contact between the protrusion 132 and the deposit deposited or formed on the upper surface of the protrusion 132 is increased, so that the deposit can be stably accumulated or generated on the protrusion 132. Thus, the amount of deposit accumulation on the protrusion 132 increases, and the deposit can cover and protect the wider region of the body member 110. [

At this time, the deposit may be a skull generated in the blast furnace as the blast furnace charge is melted or solidified. The now formed adherent layer can protect the body member 110 from heat and charge inside the blast furnace to improve the life of the body member 110.

FIG. 6 is a view showing a combined structure of a body member, a protruding member and a refractory member according to an embodiment of the present invention, and FIG. 7 is a view showing the shape of a protruding end according to an embodiment of the present invention.

Referring to FIG. 6 (a), at least a portion of the protrusion 132 may be located in the refractory member 120. That is, after the protruding member 130 is coupled to one surface of the body member 110, the refractory member 120 may be installed on one surface of the body member 110 and the protruding member 130. Thus, the projecting portion 132 may be covered with the refractory member 120 and positioned within the refractory member 120.

One surface (or a surface facing the interior of the blast furnace) of the protruding portion 132 may be located on the same line in the vertical direction with one surface of the refractory member 120 (or the surface facing the interior of the blast furnace). Thus, the protruding length of the protruding portion 132 becomes relatively long, and the amount of adherent that can accumulate on the protruding portion 132 or can be generated can be increased.

6 (b), one surface of the protrusion 132 may be covered with the refractory member 120 to be located in the refractory member 120. [ That is, the protrusion 132 may be formed inside the refractory member 120. Thus, the refractory member 120 can also cover one surface (or the projecting surface) of the protruding portion 132. Thus, the protruding length of the protrusion 132 is relatively shortened, so that the protrusion 132 can be protected in the refractory member 120 until the refractory member 120 is destroyed. Therefore, the life of the protrusion 132 can be improved.

The protruding portion 132 and the refractory member 120 may be formed by at least one surface of the protruding portion 132 contacting the refractory member 120 to improve the coupling force with the refractory member 120, An engaging groove 132c that can increase the contact area of the engaging portion 132c can be formed. For example, when one surface of the protrusion 132 is covered by the refractory member 120, one or a plurality of coupling grooves 132c may be formed on one surface of the protrusion 132. [ As a result, the area of contact between the protruding portion 132 and the refractory member 120 increases, and the refractory member 120 can be stably fixed to the protruding portion 132.

At this time, the defect grooves 132c may be formed on the same plane as the protrusions 132a and the protrusions 132b, or may be formed on different surfaces. However, the number of the surfaces on which the coupling grooves 132c are formed and the surfaces of the refractory member 120 are not limited to these, and may vary.

Also, a plurality of body members 110 may be provided and spaced apart from each other. The protrusion 132 may extend to both ends of the end body member 110. That is, the protruding member 130 may be extended to a length within the width direction of the body member 110. Accordingly, the blast furnace charge can be caught between the protrusions 132, and it is possible to suppress or prevent the charging object from stagnating and colliding with the body member 110 located on the lower side. Such a charge may serve to protect the body member 110 by covering the body member 110.

Alternatively, at least a portion of the protrusion 132 may be extended to expose the space between the body members 110. That is, the protrusion 132 may extend beyond the length of the body member 110 in the width direction. Thus, the gap between the protrusions 132 can be made small, and the protrusions 132 can stagnate the charge of a smaller size. In particular, charges that move along the space between the body members 110 may also be caught between the protrusions 132. Therefore, it is possible to more effectively suppress or prevent the charge from colliding with the lower body member 110.

At this time, as shown in FIG. 7, a portion (or an end) exposed to the space between the body members 110 of the protrusion 132 may be formed in at least one of taper and round. Therefore, it is possible to suppress or prevent abrasion of the projecting portion 132 by the charge when the charge is sandwiched between the projecting portions 132.

For example, the end of the protrusion 132 may be convexly formed. Thus, it is possible to suppress or prevent the end of the projecting portion 132 from colliding with the load to be worn. Alternatively, the end of the protrusion 132 may be concave. Therefore, it can be stably held in the concave portion of the end of the protrusion 132 of the charge.

Alternatively, the projecting portion 132 may be formed into a tapered shape by machining a sharp end thereof. Accordingly, the end of the protrusion 132 may be formed in a flat shape to suppress or prevent wear from colliding with the charge M. However, the structure and shape of the projecting portion 132 are not limited to this, and may vary.

Referring to FIG. 6, the second cooling fluid line 150 forms a path through which the cooling fluid moves and cools the protruding member 130. The second cooling fluid line 150 may be provided separately from the first cooling fluid line 140 to cool the protruding member 130. The second cooling fluid line 150 includes a second supply pipe 151 capable of supplying a cooling fluid, a second control valve 152 installed in the second supply pipe 151, one end connected to the second supply pipe 151, And may include a second moving pipe 153 installed in at least one of the connecting part 131 and the protruding part 132 and a second discharging pipe 154 connected to the other end of the second moving pipe 153 .

The second supply pipe 151 is formed in the shape of a circular pipe to form a path through which the cooling fluid moves inside. The second supply pipe 151 is disposed outside the blast furnace and is connected to a tank (not shown) in which the cooling fluid is stored, and supplies the cooling fluid supplied from the tank to the second transfer pipe 153. At this time, the second supply pipe 151 may be connected to the second moving pipe 153 installed in the body member 110 through the pipe 160, the body member 110, and the protrusion member 130.

The second control valve 152 is provided in the second supply pipe 151 and functions to open and close the path of the cooling fluid formed by the second supply pipe 151. When the second control valve 152 is opened, the cooling fluid stored in the tank can be supplied to the second moving pipe 153 through the second supply pipe 151. When the second control valve 152 is closed, The fluid may not be supplied to the second moving pipe 153.

The second moving pipe 153 is installed in at least one of the connecting portion 131 and the protruding portion 132 to form a flow path through which the cooling fluid moves. The second moving pipe 153 may be a circular pipe, and one end thereof is connected to the second supply pipe 151. Since the second moving pipe 153 can move the cooling fluid supplied from the second supply pipe 151 inside the protruding member 130, the cooling fluid, which moves inside the second moving pipe 153, (130) can be cooled. Therefore, the temperature of the protruding member 130 protruded and exposed to the inside of the blast furnace rises can be suppressed or prevented by the cooling fluid moving inside the second moving pipe 153.

The second discharge pipe 154 is formed in a circular pipe shape to form a path through which the cooling fluid moves. The second discharge pipe 154 may be connected to the other end of the second moving pipe 153 through the pipe 160, the body member 110, and the protrusion member 130. Accordingly, the cooling fluid moving inside the first moving pipe 143 can be discharged to the outside of the second moving pipe 153 through the second discharge pipe 154.

In addition, the second discharge pipe 154 may be connected to the second moving pipe 153 at a position lower than the second supply pipe 151. In other words, the other end of the second moving pipe 153 may be located at a lower height than the first end. Thus, the cooling fluid can be supplied to the upper side of the second moving pipe 153 and discharged downward. Therefore, the cooling fluid can quickly move inside the second moving pipe 153 by the gravity, and the new cooling fluid can be rapidly supplied into the second moving pipe 153 to quickly lower the temperature of the protruding member 130 have. However, the structure and shape of the second supply pipe 151, the second moving pipe 153, and the second discharge pipe 154 are not limited to these, and may vary.

As described above, the plurality of protruding members 130 are connected to the plurality of body members 110, so that the charge can be caught between the protruding members 130, the charge is stagnated and rubbed against the body member 110 Can be suppressed or prevented. Therefore, the life of the body member 110 can be improved, and the cooling fluid moving inside the body member 110 can stably protect the blast furnace 160 from blast furnace.

Also, the protrusions 130 may be formed or deposited. Thus, an adhesive layer may be formed on the protruding member 130 to cover the body member 110. Therefore, the attachment layer protects the body member 110 from the blast furnace charge, so that the durability and life of the body member 110 can be improved.

FIG. 8 is a view showing that charges and deposits are formed on protrusions according to an embodiment of the present invention. FIG. Hereinafter, an operation method of a feature-material processing apparatus according to an embodiment of the present invention will be described.

1 to 8, iron ores and coke are charged into the upper part of the blast furnace, and hot air is blown into the blast furnace by burning the coke. Molten iron can be produced in the blast furnace by removing impurities and oxygen from the iron ore with the heat and gas generated by burning the coke. A body member 110, a protruding member 130, and a refractory member 120 may be provided on the inner side of the blast furnace in order to protect the crust 160, which is an outer shell of the blast furnace, when the blast furnace operation is performed.

When the cooling fluid is supplied into the body member 110 during the blast furnace operation, the body member 110 may lose heat energy to the cooling fluid, thereby lowering the temperature. Accordingly, the body member 110 can protect the iron sheet 160 from the internal heat of the blast furnace, and the temperature of the iron sheet 160 can be lowered. Therefore, it is possible to suppress or prevent the thermal deformation of the iron foil 160 when performing the work of manufacturing the iron wire in the blast furnace.

However, in order to protect the body member 110, the refractory member 120 installed on one surface of the body member 110 may be extinguished at the end of the blast furnace life. That is, the refractory member 120 may collide with the charge in the blast furnace, and the refractory member 120 may be destroyed. When the refractory member 120 disappears, the protruding member 130 connected to the body member 110 can be exposed to the inside of the blast furnace.

The protruding member 130 may protect the body member 110 in place of the extinguished refractory member 120. At this time, the cooling fluid may be supplied into the protruding member 130 separately from the body member 110. The cooling fluid can suppress or prevent the temperature of the projecting member 130 from rising due to the heat inside the blast furnace by lowering the temperature of the projecting member 130. [

Further, the cooling fluid supplied to the protruding member 130 can cool the air around the protruding member 130. The attachment S can be easily generated or piled up by the cooled air on the upper surface of the protruding member 130 and the attachment S covers the one surface of the body member 110, You can protect it.

In addition, the blast furnace water charge M can be caught and inserted between the projecting members 130. Thus, collision of the charge M with the lower body member 110 can be suppressed or prevented. Therefore, the protruding member 130 can protect the body member 110 using the charge M and the attachment S, and the body member 110 protects the skin 160, The manufacturing process can be performed stably.

As described above, the plurality of protruding members 130 are connected to the plurality of body members 110, so that the charge can be caught between the protruding members 130, the charge is stagnated and rubbed against the body member 110 Can be suppressed or prevented. Therefore, the life of the body member 110 can be improved, and the cooling fluid moving inside the body member 110 can easily cool the blast furnace skin 160.

Also, the protrusions 130 may be formed or deposited. Thus, an adhesive layer may be formed on the protruding member 130 to cover the body member 110. Therefore, the attachment layer protects the body member 110 from the blast furnace charge, so that the durability and life of the body member 110 can be improved.
