Description
Technical field
The present invention relates to the furnace body protection sidings protected for the furnace wall to the blast furnace for being exposed to high temperature etc..
Background technique
All the time, use furnace body cooling device (following to protect blast furnace from the damage of thermic load in furnace
It is recorded as siding).The siding of furnace body protection has cooling use using production such as cast iron, rolling copper, cast coppers in web proper
Water route.In recent years, in order to cope with the high heat load of blast furnace, it is desirable that the higher siding of cooling capacity, as a result, more and more
The ground made of copper siding high using thermal conductivity.
In such furnace body protection siding, be formed in the cooling water road of web proper according to design philosophy, what is used
The difference of kind of material and it is different.That is, according to material, it is however generally that, cylinder iron steel piping is wrapped in the case where cast iron
Heart casting is formed water route (drilling) by machining in the case where rolling copper, forms water route by casting in the case where cast copper.
Hereinafter, to because by machining production thus the dimensional accuracy in water route is good, also almost without pouring in terms of material
The worry of the defects of " hole " that is generated when note, therefore using a fairly large number of furnace body protection siding being made of rolling copper into
Row explanation.
Fig. 7 (a), (b) are respectively constituting for an example for the furnace body protection siding formed by rolling copper for indicating previous
Main view and its cross-sectional view along line A-A.In example shown in Fig. 7 (a), (b), in the web proper 51 formed by rolling copper
On be provided with a plurality of water route 52 (being herein 3).Each water route 52 is formed in web proper by being machined (drilling processing)
51.Water route 52 is by the water route main body 52a that penetrates through on the length direction of web proper 51 and orthogonal with the water route main body 52a
Plumbing is constituted with access 52b-1,52b-2, and the plumbing is used for and plumbing piping 53- with access 52b-1,52b-2
1,53-2 is connected to.The both ends of water route main body 52a are sealed by welded seal component 54-1,54-2.In plumbing access
On 52b-1,52b-2, the plumbing formed by steel pipe or copper pipe piping 53-1,53-2 are fixed with by welding respectively.?
More (being herein 4) bolts 55 are provided in web proper 51.
An example as shown in Figure 8 is such, the furnace body protection siding of above-mentioned composition using bolt 55 and nut 56, pass through
Screw threads for fastening and the iron sheet 61 for being fixed on blast furnace.The plumbing of web proper 51 is penetrated through with piping 53-1,53-2 in blast furnace
The hole opened up on the iron sheet 61 of furnace body is supplied water, draining from furnace body outside.
In the case that repetition thermic load in blast furnace causes copper siding damaged, reason is mostly the leakage from cooling system
Water.In recent years, the increase that micro mist carbon is blown into causes the thermic load applied to furnace body significantly to increase, and siding ratio is set by the design phase
Breakage occurs earlier for the service life for thinking of expectation.It soaks in the furnace as caused by above-mentioned siding breakage and hinders the steady of blast furnace significantly
Fixed operation.Therefore, in the case where confirming leak in operation, implement to stop at arranging for the cooling water recycled in the water route of siding
It applies.Stopped by the cooling water, the high temperature that copper siding is exposed in furnace and the environment worn by raw material bring, therefore, wall
Plate main body itself disappears in a short time.Due to the disappearance (disappearance of refrigerating function) of copper siding, cause high furnace main body iron sheet will
It is directly exposed to high temperature, causes iron sheet crackle, thermal deformation, blast furnace operating itself becomes difficult to continue.
The leak of copper siding can be mixed into cooling water by the gas in State of Blast Furnace and is found, can by investigation result
Supposition causes the position of leak as follows.
(1) because deforming caused by high heat load, and to be piped in the plumbing water route of web proper and plumbing
Welded joint at crack, so as to cause leak；
(2) because being deformed caused by high heat load, and make for water route will be formed by the machining of web proper
When extra opening block used in seal member weld part at crack, so as to cause leak；
(3) since mechanical strength and hardness are low, to open on cooling water channel because wearing caused by raw material in furnace
Hole, so as to cause leak.
Therefore, it for the operation steady in a long-term of blast furnace, needs to solve the leak of copper siding, realizes that the service life extends.
It rolls in copper siding, cooling water channel is formed in web proper itself, therefore, compared in cast iron siding etc.
For the casting piping of use carries out water flowing cooling, cooling capacity is higher.But in rolling copper siding, in most cases, by
In web proper damage and cause the breakage of cooling water channel, lead to the disappearance in advance of web proper.Therefore, copper siding is rolled
Eventually become short life.On the other hand, the cooling channel of cast iron siding is made of casting piping, with web proper independence.Cause
This, web proper damage influence caused by cooling channel is few, but in casting piping, is formed between piping and web proper
Boundary layer thermal conductivity is reduced, therefore cooling capacity is not high.
As the technology for the long lifetime for solving the problem above-mentioned, realizing copper siding, by machining etc. in copper
Slot is opened up, the piping of steel is fitted into the slot on the outside of the furnace of siding, the use of the structure of the plate of the fixed steel of bolt is known
(patent document 1).
