Apparatus for maintaining in coking chamber of coke oven}

The present invention relates to a repair gas for preventing the door gas leakage of the coke oven, and more particularly to a repair gas for preventing the door gas leakage of the coke oven for maintenance and repair of the door for preventing the door gas leakage of the coke oven.

In general, coke ovens installed in steel mills are composed of many types of fire-retardant and large and small steel structures and concrete structures. It is a high-temperature industrial furnace that uses high heat obtained by burning fuel gas as a heat source and produces coal by coke. .

The coke oven is a device for coking the coal charged in the carbonization chamber for a certain period of time, after which the coke is extracted from the carbonization chamber to extinguish the cold coke, the cold coke is transferred to the blast furnace to melt the water It is used as a breathable and heat source.

Such a coke oven is equipped with a plurality of carbonization chambers, the coke production operation is carried out with the coal contained inside the carbonization chamber, each carbonization chamber is temporarily opened during the production operation to extract the coke coal, that is, coke. . The opening of the carbonization chamber is made by attaching and detaching the coke oven door disposed on the side of the carbonization chamber.

However, the coke oven door may also cause gas leakage. To prevent this, a movable bogie for repairing the door is installed at the bottom of the rail.

 In addition, the trolley is provided with a device capable of raising and lowering, so that the operator can perform work while moving up and down, left and right.

Conventionally, a fire frame repair means installed in a moving frame provided to be movable on one side of a carbonization chamber of a coke oven and a driving member provided in the moving frame, and inserted into the carbonization chamber to repair the carbonization chamber, and the And a lift-type maintenance unit arranged to prevent interference with the fire wall repairing means and having a fire wall cleaning means for cleaning the inner wall of the carbonization chamber, wherein the driving member is installed on the movable frame to be movable. A first horizontal member entering into the inside, a second horizontal member installed in the moving frame in parallel with the first horizontal member and moving to enter into the carbonization chamber, and coupled to one end of the first and second horizontal members And a vertical member for providing a movement path between the fireproof wall repair means and the fireproof wall cleaning means, and the fireproof wall repair water And a refractory sprayer rotatably mounted on the first elevating base, the refractory injector spraying refractory to repair the refractory wall, and the refractory wall cleaning means is vertical. A second elevating base having a through hole formed to prevent interference with the fireproof wall repairing means provided in the member, the second elevating base rotatably installed on the vertical member, and a rotatable member rotatably installed on the second elevating base; The carbonization chamber maintenance apparatus of the coke oven has been filed in the Republic of Korea Patent Registration No. 10-0910483, characterized in that it is rotatably installed on the rotating member and provided with a cleaning member contacting the fireproof wall to remove carbon.

However, such equipment has a drawback that the equipment is not properly moved due to the high temperature due to the nature of the coke oven, which maintains a high temperature of about 1250 ° C.
