Field of the Invention The present invention relates to a hot wall of a coke oven side wall of a coke oven, which has an appropriate expansion allowance when the bricks of the side wall of the coke oven are reloaded while hot, which is one of the life extension of the coke oven. It relates to a repair method for transshipment.

用いられている。2. Description of the Related Art In a coke oven, carbonization chambers for coking coal and combustion chambers for supplying heat to the carbonization chambers are alternately arranged, and heat is supplied to the carbonization chambers from the side wall of the carbonization chamber. Done by. Then, the coke after carbonization is pushed out from one of the carbonization chambers by the pusher and discharged. For this reason, silica stone bricks are often used for the side wall, since the volume change at high temperature is relatively small, and besides, the thermal conductivity is good and the mechanical strength is large.

を積み替え補修することにより延命が図られる。The furnace is always kept at a high temperature of over 1000 ° C., and once fired, the brick collapses due to contraction and ends its life when cooled again to room temperature. However, since the side wall is exposed to the harsh condition and has a large area as described above, after 20 years or more, a part or all of the side wall can be transshipped and repaired to prolong the life.

置部となり、側壁を全高にわたって積み替える場合は炉
頂部が残置部となる。The coefficient of thermal expansion of silica stone bricks varies greatly depending on the temperature range and expands rapidly up to about 300 ° C.
When it exceeds 600 ° C, it becomes gentle. For this reason, at the time of transshipment, the furnace is cooled, but the inside of the furnace is set to a temperature slightly higher than 600 ° C, and hot bricks are transshipped. When reloading this side wall, there is always a remaining part that does not
When a part of the side wall is transshipped, the remaining side wall and the furnace top become the remaining part, and when the side wall is transposed over the entire height, the furnace top becomes the remaining part.

０ｍｍの側壁では約７０ｍｍも高さが変化する。Since the remaining portion maintains the position before the transshipment, it is necessary to prevent excessive stress from being applied to the residual portion due to thermal expansion of the transshipment portion. That is, since the transshipment portion thermally expands due to the temperature rise after repairing, it is necessary to perform construction in consideration of an expansion allowance for absorbing this thermal expansion amount.
The expansion of the wall is based mainly on the thermal expansion of silica stone bricks, and although the coefficient of thermal expansion at high temperatures is relatively small, the total height is 600
The height changes about 70 mm on the 0 mm side wall.

ンモルタルを施工し膨張量を吸収する方法である。Conventionally, there have been two methods as measures against this. This is a method in which cushion mortar is used as the joint material, the joint thickness is applied to a thick joint of 4 mm to 8 mm, and the expansion amount is absorbed by utilizing the compressibility of the cushion mortar.
Another method is to use silica mortar, which is the same material as the brick material, as the joint material, and apply it to a normal thickness of 4 mm to 5.5 mm, but apply ceramic fiber or cushion mortar at the top to increase the expansion amount. It is a method of absorption.

するには耐用面で問題があった。However, since the lower part of the side wall has to support the upper brick, the joint is required to be stronger than the upper part. In the method,
Cushion mortar has a low strength, is easily deformed during construction, and has a problem in supporting the upper brick. Further, the cushion mortar is vulnerable to wear and has a problem in terms of durability when used on the entire surface including the lower portion of the side wall.

りがちである。In the method of (1), since the siliceous mortar has no contractibility, the expansion amount is absorbed in the uppermost stage, but the ceramic fiber or the cushion mortar inevitably becomes thicker than the range of the joint thickness. Similar to cushion mortar, ceramic fiber has low strength and is easily deformed. For this reason, there is a problem in supporting the upper brick, and a gap of a joint is easily formed at the boundary with the remaining portion, and a gas leak tends to occur.

A first aspect of the present invention uses a shrinkable ceramic board as a part of a wall member in addition to a silica stone brick when hot-loading and repairing a side wall of a carbonization chamber made of silica stone, and a silica stone as a joint material. This is a hot transshipment repair method for the side wall of the coke oven carbonization chamber that uses both high quality mortar and cushion mortar.

一部に限定して使用し、他の目地には強度の大きいモル
タルを使うことも可能となる。If the expansion and absorption allowance corresponding to the thermal expansion amount of the silica stone brick is applied only to the joints, the cushion mortar with low strength must be used entirely. However, there are some ceramic boards that have a large compressibility and reach several tens of percent, and the cushion mortar is limited to a part of the side wall by making the contractible ceramic board bear part of the expansion and absorption allowance. It is possible to use mortar with high strength for other joints.

ークス炉炭化室側壁熱間積み替え補修方法である。[0012] A second aspect of the present invention is that silica stone bricks are piled up using a siliceous mortar in a joint extending from a lower portion of the side wall to a central portion in a height direction, and a silica stone is formed using a cushion mortar in a joint extending from the central portion to an upper portion. Piled bricks,
In addition, the method of hot-reloading repair of the side wall of the coke oven carbonization chamber is characterized in that a compressible ceramic board is used between the uppermost silica stone brick and the furnace top.
【００１３】目地材として珪石質モルタルとクッション
モルタルを併用すると、強度が要求される目地に珪石質
モルタルを使用することによって、クッションモルタル
の強度不足を補うことができ、同時に、強度要求が緩和
される目地にクッションモルタルを使用することによっ
て膨張吸収代として作用させることができる。When silica mortar and cushion mortar are used together as joint material, the lack of strength of cushion mortar can be compensated by using silica mortar for joints which require strength, and at the same time, strength requirement is relaxed. By using cushion mortar for the joint, it can act as an expansion and absorption margin.

てクッションモルタル目地の可縮範囲を有効に活用する
ことができる。That is, a siliceous mortar is used for the joint on the lower side where a large load is applied, that is, the joint from the lower portion to the central portion in the height direction, and a cushion mortar is used for the joint from the central portion to the upper portion where the load is relatively reduced. To do. By doing so, the expansion amount becomes larger under a low load than under a high load for the same amount of thermal expansion, so that the contractible range of the cushion mortar joint can be effectively utilized by the above arrangement. .
【００１５】又、下部ではコークスを押し出す際に特に
強い摩擦が生じるが、下部構造は耐摩耗性のある珪石質
モルタル目地のみで構成し、耐摩耗性に劣るクッション
モルタルの下部への配置を避けることが望ましい。In the lower part, particularly strong friction occurs when pushing coke, but the lower part structure is composed of only wear-resistant silica mortar joints, and avoids disposing the cushion mortar, which has poor wear resistance, in the lower part. Is desirable.
【００１６】中央部から上部にかかけては、クッション

て使用する方が得策であり、又その高可縮性を効果的に
活かすことができる。From the central part to the upper part, it is also possible to use a shrinkable ceramic board which is more shrinkable and stronger than the cushion mortar. However, the shrinkable ceramic board is more expensive than silica bricks and mortar, and is inferior in thermal conductivity to silica bricks, so it is better to use it only in the upper part, and its high shrinkability is effective. Can be utilized effectively.

元する。このため、炉頂部の残置部レンガと側壁最上部
との境界に使用すると、残置部レンガとの間に隙間がで
きずガスリークを防止することができる。In particular, the shrinkable ceramic board has elasticity, and when the stress is removed, the contracted state is restored to the original size. For this reason, when it is used at the boundary between the remaining bricks on the top of the furnace and the uppermost part of the side wall, a gap is not formed between the remaining bricks and the gas leak can be prevented.

る。A third aspect of the present invention is 33% of the total height from the bottom of the side wall.
The above method is a hot transshipping repair method for the side wall of the coke oven carbonization chamber, in which siliceous mortar is used for joints in the range of to 55%.

りや押し出されるコークスによる目地損傷が増加する。As mentioned above, the lower part of the side wall is required to have strength and wear resistance, and silica-based mortar is preferable as the joint material. However, since silica-based mortar is poor in shrinkability, the total height is 5
If it exceeds 5%, the expansion and absorption allowance may be insufficient. If it is less than 33% of the total height, the use area of the cushion mortar used on it will be wide, and the joint damage will be increased by the fatigue of the joint and the coke pushed out.

る。BEST MODE FOR CARRYING OUT THE INVENTION In a coke oven that has been in operation for 26 years, the side wall of the carbonization chamber is being damaged, and if left as it is, there is a risk of burial, so hot repair was performed.
An embodiment of the invention will be described using an example in this case.

At the time of repair work, cool the temperature of the carbonization chamber to 700 ° C, insert a heat insulation box into the room, and raise the temperature inside the heat insulation box to 50 ~
The work was carried out while maintaining the temperature at 70 ° C. The boundary brick with the unrepaired part was hung with bolts or fixed with a jack to prevent it from collapsing. Further, in order to prevent spalling due to cooling, the boundary portion was cured with ceramic fiber.
