BACKGROUND
[2]
Blast furnace is charged after receiving the charge, such as iron ore and coke in the interior, hot air was blown into the melt inside the charge to produce a molten iron. Goro is because the facility that are constantly exposed to high temperature environments are vulnerable to heat damage. Accordingly, the blast furnace is provided with a cooling system. A conventional cooling system, through the stacking eve (stave) and the blast furnace cheolpi cheolpi installed on the inside of the blast furnace is composed of a cooling water pipe or the like extending into the interior of the stacking Eve.
[3]
On the other hand, Stephen Eve there is produced to facilitate the heat transfer to the copper, the copper is therefore the hardness is lower than the charged water. That is, stacking Eve is easily worn in the blast furnace charging water. Therefore, stacking Eve is the front dovetail groove (dovetail groove) is formed in the dub refractory block having a dovetail groove in the tail is attached to protect the stacking Eve.
[4]
However, still the blast furnace is charged with water repeated direct contact with the refractory material block, and thus, since the shear stress concentration and repeated in the dovetail of the refractory block, is inevitable damage.
[5]
That is, the stay while beuwa dovetail coupling structure charged with water and the refractory blocks in the refractory block is repeatedly contacted by a shear stress in the dovetail of the refractory block is concentrated and repeated, is a refractory block damage to the desired service life before being dropped prematurely there is a problem. In this case, the cooling system of the blast furnace is suffered serious damage, and thus lose their cooling capacity. After all, it is subjected to thermal damage to the body of a blast furnace. This will cause the furnace to replace the whole or part to be replaced with a cooling system, as this cost is generated, and stopped production of the molten metal during the low productivity problem.

[46]
1 to 3, a description of the container according to embodiments of the present invention.
[47]
Containers according to embodiments of the present invention (1) includes a plurality of block structure 20 is disposed on the inner surface of the cylinder 10, and a cylinder 10 having a space therein.
[48]
Cylinder 10 has a shell capable of supporting the structure forming the outer wall of the container 1, the container 1, which extends in the vertical direction and having a space therein, and the interior may be open to the upper side. Cylinder 10 to the molten iron, for example, comprises a blast furnace capable of producing molten iron in detail may include cheolpi of the blast furnace.
[49]
Block structure 20, is disposed on the inner surface of the cylinder 10, the inner side are disposed along the inner side circumference of the cylinder 10 at a plurality of locations spaced apart in the vertical direction, the whole so as to cover may come into contact with each other while, and by at least one of the block 22 and the engaging member 24 to be described later it may be bonded to each other. Block structure 20 is to protect the cylinder 10 from the internal opening of the tubular body 10 during manufacture of molten iron. In addition, the block structure 20 has a first contact with the cylinder 10 in the contents of water, for example blast furnace charged with water (iron ore and coke, and so on) that is charged to the cylinder 10 can be prevented from coming in direct contact with the water charged.
[50]
Block structure 20, one-way (e.g., right and left direction or longitudinal direction) and second direction (e.g. vertical direction or the height direction), one side of having a one surface (21a), body 21, body 21 extends in the (21a) as each coupled to a plurality of blocks (22) in contact with each other.
[51]
Body 21 may comprise a member of plate shape extending in one direction and the other direction, for example, the stacking Eve. Body 21 there is provided a support structure that supports the block 22 to a surface (21a), the support structure will be, for example, a concave-convex structure, and, more particularly, a support having a plurality of dovetail grooves (21b) structure may be, for example, a dovetail support structure. Block 22 is provided with a supporting protrusion, for example dovetail, which will be described later on the back surface, the tail groove (21b) is dovetail dub is the fitting is supported block 22 is constrained on one side of the body 21.
[52]
On the other hand, the dovetail groove (21b) and a dovetail, each may be the respective edges extending in the one-way processing chamfer (chamfer) or fillet (fillet). Referring to FIG. 2 (a), the dovetail groove (21b) and the edge of the dovetails are indicates that the curved surface shape of the fillet process, looking at FIG. 2 (b), dub each tail groove (21b) and the dovetail It indicates that the edge is an angular shape. In the structure of Figure 2 (a) it is possible to prevent the stress concentration on each corner, there is a structure in the advantage to reduce the respective manufacturing processes and cost of the (b) of Fig.
[53]
A plurality of blocks (22) body (21) one side (21a), for example so as to cover the front full dovetail groove (21b) is fitted in from the charged water and the first opening and the impact the main body 21 charged water while contacting the to protect, at this time, the stress is concentrated on the dovetail. In particular, the water contents of each block 22 receive a force when applying a concentrated force to the plurality of block 22, the block portion 22 without application of force is made uniform in a strong stress is concentrated on the dovetail.
[54]
Of the embodiments of the present invention, a plurality of blocks 22 is an engaging groove and engaging projection to be described later to the surfaces facing each other in at least one direction of the one direction and the other direction is formed or bonded to each other, or the second direction and the one-way at least a coupling member to be described later at a plurality of locations spaced in a direction to be fitted therethrough in at least one direction of the one direction and the other direction.
[55]
That is, the plurality of block 22 surface in contact facing each other are combined or in contact with the three-dimensional conformation of by the engaging projection and the engaging groove, the structure being rigidly coupled to each other by a coupling member, this structure is for example one another It is very effective in the delivery of the load to be compared with the surface opposite to the simple contact of a two-dimensional planar structure. By this structure, it is possible to distribute the load concentrated on the part block 22 in the other block 22. Therefore, it is possible to evenly distribute the load of the entire plurality of block 22. At this time, in that the load blocks 22 in the block structure 20, which neighbors may be dispersed as a matter of course.
[56]
Thus, it is possible to prevent excessive force is concentrated on each of the plurality of block 22, it is effective to suppress or prevent the stress concentration on the structural weakness of Mrs. dovetail block 22. That is, it is possible to extend the life of the block 22, in the end, it is possible to extend the life of the entire plant.
[57]
On the other hand, the block structure 20 may be provided with a refrigerant pipe, for example as the cooling member 23, the refrigerant pipe extends into the interior of the body 21 by, for example through the tubular body (10). Block structure 20 may serve as a cooling system of the blast furnace in a manner that the refrigerant, for example supplying cooling water to the refrigerant pipe and circulation.
[58]
